Tomatoes – actually to be more precise – Heirloom Tomatoes
Let me tell you that I am just crazy about eating tomatoes – I mean real good quality tomatoes that actually have taste and flavor. I cannot usually find these in most supermarkets and if I do, they are quite pricey but still leave something lacking in flavor and taste, usually because they have been picked before they have had a chance to ripen and usually have sat in storage and coolers, probably shipped in from some far away place. There really is nothing better than local grown and vine ripened heirloom tomatoes so they have had time for the full flavor to develop. Growing tomatoes in Aquaponics is easy and ever one who has an Aquaponics System can certainly enjoy them fresh. However, to increase the taste and flavor of tomatoes grown in Aquaponics, I have concluded the following during my research over the last three years or so.
First and foremost, try to only grow “Heirloom” tomatoes. So what is “Heirloom”? Seeds of plants that have passed down by families over the years (usually over 50 years), and those that have preserved the unique taste, flavor and character are usually referred to as “Heirloom”, sometimes also called “open pollinated” or “Heritage” (in UK). The fruits may not all look uniform and be of different size and shapes. To those who are interested in actually tasting their food, these are sought after and command a higher market price. As awareness is growing of the associated additional health benefits of eating such food, their demand is on the rise. You as a grower can certainly benefit from this “Niche” section of the food market. Yes it will take time and patience to locate the consumers who will appreciate your unique “heirloom” produce grown locally and naturally. Let me assure you that once they have tasted the produce, they will not be going elsewhere and will become loyal customers so long as you continue to grow such wonderful tomatoes.
Growing heirloom tomatoes in Aquaponics to attain the full flavor and taste, I have found that the best results are obtained when I grow them in pots filled with my own “soil mix” and place them either in rafts or recirculating media wicking beds. This allows the tomato plants to always have the effluent rich re-circulating fish water that is high in Nitrogen as well as allow “top-side dressing” by adding very small amounts of natural and organic material such as vermicompost, high phosphorus bat guano, bone meal and rock salts such as Azomite. As there is not “top” watering other that the occasional spray of Vermicompost Tea, there is very little chance of any significant leaks of such into the Aquaponics System water so as to harm the fish. I have found that we have a significant increase in the fruit yield of each tomato plant as well as enhanced taste and flavor. Yes there is one major disadvantage than growing regular tomatoes. These heirloom tomatoes require very careful handling. Many of them have thin skins and a short shelf life once picked. They are thus ideally suited to the small urban farmer serving the local customer – that would be you.
“Is it profitable?”
So what is the average selling price of a pound of Heirloom Tomatoes? I “goggled” this and came across a range from $1.00 to a high of $5.50, the average being $3.50. I was recently informed of a nearby Hydroponic grower getting $7.50 per lb! Well it is early in the tomato season. You can command a higher price at either end of the season as other local growers may not have the produce available for market – here a controlled environment such as a greenhouse /hoop house will certainly make economic sense. Growing them in Aquaponics can help you command 50c to $1.00 lb more especially if you can allow ”u-pick” as well as “mix & match” the varieties. The yield per plant varies depending upon the heirloom tomato plant variety and growing environment. In independent studies the range that has been seen is a low of 9lbs to a high of 19lbs. For our example we will use a low yield of only 14lbs per plant. You should space your heirloom tomato plants at least 15 to 18 inches apart if using a staggered raft formation and vertical trellising – ideally 2 feet if you have the space. If they are to be placed in re-circulating media beds I recommend a minimum of 2 ft distance in each direction and vertical trellising. You will have to keep ahead of the heavy leaf growth and may occasionally have to prune (be careful not to over do this), and ensure proper support of the vertical trellising. I try to mix and match the heirloom tomato varieties as some plants are more prolific than others. I must confess I also enjoy seeing the different colors of the various heirloom tomatoes. You also need to ensure that there is plenty of air circulation.
If you had a fifty foot long by 4 foot wide grow bed area (raft or media), so 200 sq. ft. space, and the heirloom plants were spaced at 2ft staggered, you should be able to plant at least 50 plants per growing season. Assuming that we receive an average of 14lbs heirloom tomatoes per plant and just the average price of $3.50 per lb, each growing season should provide you with a gross return of around $2,500. Now if you have a controlled growing environment, you may be able to command much higher prices at the start and out of the normal growing season. Here in Central Florida we experience at least two growing seasons, so could earn around $5,000 from the 200 sq foot of growing area allocated to heirloom tomatoes. In a controlled growing environment you may be able to stagger the planting so as to have virtually continuous growing thus substantially increase your revenue form the sale of heirloom tomatoes. Remember that you should grow multi crops to the niche market that you identify for your area and climate so as to maximize your revenues. There are other products you can grow in Aquaponics other than leafy greens and still make a profit – remember Okra, Eggplant, Hot Peppers, culinary herbs and so on.
I will request my daughter to include some Heirloom Tomato recipes on her Blog www.lovelaughmirch.com
As to whether it is “profitable” from a health point of you, this is going to be your decision. Let me help you a little. Growing them by aquaponics means ensures that you are assured the best natural taste. As I was quoted in the recent article in Cornell University Small farm Program Newsletter – the Urban Gardening section “This was a far superior way to grow it locally, grow it naturally, without having to resort to harmful pesticides and fertilizers and such, because if I did, my fish would die.”
I have listed just some of the health benefits of eating heirloom tomatoes in the following link: http://jenubouka.hubpages.com/hub/Heirloom-Tomato-Beginners-Guide
In future “What shall we grow today?” article’s I will write about some of the vegetables and culinary herbs that you can grow in Aquaponics. Please let me know if there are any vegetables you would like to grow in Aquaponics and know more about them.
Okra – aka “Ladies Fingers”, “Kingombo”, “Gumbo” and “Bhindi”
During the last two years or so, I have found that you can grow almost any vegetable and plants that you choose to in Aquaponics. You may need to adapt the grow beds and practice hybrid aquaponics as I do to increase your range of products. I have successfully grown broccoli, carrots, eggplants, daikon and radishes, fennel, fruit trees, kohlrabi, herbs, okra, onions, pumpkins, marrows, gourds, tomatoes, strawberries, peppers – hot & sweet just to name some. I have also seen others grow corn and some even sweet potatoes via wicking beds. One really needs to expand their horizon and realize that there are really very few items that will not grow well in Aquaponics systems. Yes there are a few items that are just not cost effective at present such as grains and rice. There is research being done on these products and I am sure that very soon these too will become economic to grow via Aquaponics means.
Today I am going to write about one of my wife’s favorite items that we grow at Sahib Aquaponics, Okra. We call it by the Hindi/Urdu Name Bhindi. This much loved vegetable is a favorite of many and is usually grown in hot weather, one of the few that does not wilt and die as the temperatures rise. The green pods when cooked release a “goo” or slime which is considered by many to be beneficial to health. Okra can be eaten raw, boiled, fried, sautéed, stir fried, stuffed, and included in stews. The leaves can also be eaten, usually in salads.
Okra plants can grow up to 9 feet tall and with uncut Okra fruit, can weigh a lot hence they are not good candidates for “raft” Aquaponics. They are better suited to deep media beds preferably containing 3/4inch rocks. Grow them direct from seed and avoid the transplant shock. Although I have grown a hybrid variety from saved seeds, I do prefer to grow the “Clemson Spineless”. Each plant may only have one or two Okra pods maturing at any one time and you should pick these often. Try to pick the pods when they are 3 to 5 inches, although I must confess that in Aquaponics, they tend to grow that almost every day! If I forget to pick them for a couple of days, they have grown to 10 to 11 inches tall and fat as a cucumber. Hat is not always a good idea as letting them grow to a larger size tends to make them woody and lose their taste. My Aquaponically grown Okra are honestly the very best tasting “Bhindi” that I have ever eaten. When planting Okra you do need a lot of room as you should plant a number of plants if you would like to be able to harvest enough pods for a meal once or twice a week.
You can eat Okra right off the plants or cook them in numerous ways. They can also be frozen or pickled. You can cut them in ¼” to ½” pieces and stir fry then with onions and spices, or coat them with seasoned corn meal and deep fry them. They can be stuffed with spices, other stuffing or even cooked ground meat and then stir fried. Gumbo is another way to eat Okra. In order to get the maximum health benefits of Okra, try to avoid over cooking it and avoid deep frying. Okra is an excellent source of many nutrients such as Vitamin A, Vitamin B6, Vitamin C, Calcium, Copper, Iron, Potassium, Magnesium, Niacin, Zinc as well as containing Folic Acid. It is considered a weight loss food with optimum health benefits. The fibers found in Okra are supposed to help stabilize bold sugar, improve the functioning of the intestinal tract and help provide the body with good bacteria for the digestive system.
I have found the following web article on Okra to be helpful and am sharing it with you http://www.neurophys.wisc.edu/ravi/okra/ It also contains some recipes. I will request my daughter to include some Indian Bhindi recipes on her Blog www.lovelaughmirch.com
Okra!
“Is it profitable?”
In Pure Economics 101 terms, it all depends! If you live in very hot climates like Central Florida, your choice of produce to grow for market is limited during the hot summer. If you have the space and the appropriate Aquaponics set-up, growing Okra during the hot season and provide you with a stream of income that was non-existent during this hot period of the year. If you had a fifty foot long by 4 foot wide media filled grow bed area, so 200 sq. ft. space, you should be able to plant at least 120 plants – spacing them 12” to 15” apart. Once they start to produce fruit, you should be able to harvest approx. 30lbs to 40lbs weekly. Organic Okra, if available (and you know as you will hopefully educate your customer that Aquaponically grown is much superior), was selling for $2.99-$3.50/lb at the local farmer’s market. Say if you have a 20 week production harvest that could result in $3,000.00 plus additional income. Not as much as one could earn if growing tomatoes or green leafy veggies. However you could not grow them in this hot climate without some serious climate control environment! By the way, you can still grow basil, mint, hot peppers and gourds / melons in the open space of the media grow beds thus further add to you farm income.
As to whether it is “profitable” from a health point of you, this is going to be your decision. Let me help you a little. Growing them by aquaponics means ensures that you are assured the best natural taste. As I was quoted in the recent article in Cornell University Small farm Program Newsletter – the Urban Gardening section “This was a far superior way to grow it locally, grow it naturally, without having to resort to harmful pesticides and fertilizers and such, because if I did, my fish would die.” I have listed just some of the health benefits of Okra. Do you know, this is one vegetable that is so valued in Indian cuisine that had resulted in India becoming the largest grower of Okra. Ayurvedic medicine states numerous health benefits of eating Okra. Here is another link detailing information on Okra as a “Body Cleanser” http://www.ehow.com/about_5471466_information-okra-body-cleanser.html
In future “What shall we grow today?” article’s I will write about some of the vegetables mentioned above as well some other less known such as Bitter Melon (Kerela), Fenugreek (Methi), Malabar Spinach and Moringa (Drumsticks). Please let me know if there are any vegetables you would like to grow in Aquaponics and know more about them.
A question that I am often asked is “Other than the lettuces and leafy greens, what else can you grow in Aquaponics?” That is then followed by, “Is it profitable?”
During the last two years or so, I have found that you can grow almost any vegetable and plants that you choose to in Aquaponics. You may need to adapt the grow beds and practice hybrid aquaponics as I do to increase your range of products. I have successfully grown broccoli, carrots, eggplants, daikon and radishes, fennel, fruit trees, kohlrabi, herbs, okra, onions, pumpkins, marrows, gourds, tomatoes, strawberries, peppers – hot & sweet just to name some. I have also seen others grow corn and some even sweet potatoes via wicking beds. One really needs to expand their horizon and realize that there are really very few items that will not grow well in Aquaponics systems. Yes there are a few items that are just not cost effective at present such as grains and rice. There is research being done on these products and I am sure that very soon these too will become economic to grow via Aquaponics means.
Today I am going to write about one of my favorite items that we grow at Sahib Aquaponics, part of the hot pepper family – Cayenne Peppers. In future posts I will write about other items that we successfully grow in our hybrid aquaponics systems and provide some information as to the benefits of consuming such and recipes of how we cook with them.
As to whether it is “profitable” from a health point of you, this is going to be your decision. Let me help you a little. I am sure that you are aware of the toxic effects of eating food that has been grown by using harmful pesticides and chemical fertilizers. Growing Chili peppers in Aquaponics, whether Cayenne or one of the other 400 varieties, eliminates the harmful pesticides or chemical fertilizers so prevents this source of toxins to your body. There is considerable research available to you as to the health benefits of eating chili peppers. Cayenne peppers are being used to cleanse and detoxify the digestion system, stimulate blood circulation as well as reduce & naturalize acidity in the body. They are considered to be anti-inflammatory and have “been used for a variety of diseases and ailments including heartburn, delirium, tremors, gout, paralysis, fever, dyspepsia, flatulence, sore throat, atonic dyspepsia, hemorrhoids, menorrhagia in women, nausea, tonsillitis, scarlet fever and diphtheria.” Dr. Edward Group -17 Health Benefits of Cayenne Pepper. They also have excellent nutritional value. “Red chilies contain high amounts of vitamin C and carotene (provitamin A). Yellow and especially green chilies (which are essentially unripe fruit) contain a considerably lower amount of both substances. In addition, peppers are a good source of most B vitamins, and vitamin B6 in particular. They are very high in potassium, magnesium, and iron. Their high vitamin C content can also substantially increase the uptake of non-heme iron from other ingredients in a meal, such as beans and grains.” Now you can see why chili peppers are considered as being an essential item in good health, part of the “Spice of Life” club.
I like the taste of Cayenne peppers so have a preference to using them often. We eat them fresh in salads or add them to my food (green or red), as well as dry them for use later, either as whole or powdered. Indian food just would not taste as good without adding chili peppers (mirch). My daughter has even named her food blog “Love Laugh Mirch”. Now I realize that eating chili’s can be difficult for many who have never had any hot spice added to their food. All I can suggest is, try to add a little hot sauce or fresh chili pepper (remove the seeds at first), to your food. You will soon really start to enjoy the sensation and crave for more. Pretty soon, you too will be advocating their use and growing as many of them as possible. Welcome on board

I was surprised to discover that chili peppers did not originate in India as Black Pepper (also known as “Black Gold”), but in the Americas. Christopher Columbus is credited as being one of the first Europeans to encounter them and called them “peppers” as they tasted spicy and hot, unlike any other food. He thought that he had reached India by sailing west in order to prove that earth was round. How the Chili Peppers travelled to India is still being debated, whether by Portuguese traders, Muslim merchants or Chinese silk merchants. Once they arrived in India, they were welcomed and became part of everyday food and being used in Ayurveda medicines.

Sahib introduces an AquaVermiponics system in order to have a quality supply of ‘casting tea”, also known as “compost tea” always available for foliar spray for his Aquaponically grown plants and produce. So what is Aquavermiponics?
Aquavermiponics is the combination of Aquaculture, Hydroponics and Vermicomposting. How Vermicomposting is added to Aquaponics can vary to some extent as to the need for the particular application. Why add Vermicomposting to the better than organic method of growing food using Aquaponics? To answer this one has to know a little about both Aquaponics as well as Vermicomposting. In Aquaponics, there can be no harmful pesticides or chemical fertilizers added to the system. Even products that are approved for use in organic gardening can result in disastrous consequences if added to an Aquaponics system. Take Neem Oil as an example.
Being from Indian Ancestry, naturally I am familiar with the many beneficial qualities that Neem Oil offers such as being a natural insect repellent and a safe pesticide that is organically approved. It has been found to be effective in controlling such pests as white flies, aphids, scales, mealy bugs, spider mites, locusts, thrips, and Japanese beetles. Neem Oil is also biodegradable, breaking down quickly and it is also considered to be non-toxic to mammals, birds, bees or earthworms. Neem Oil is certainly a wonderful product in organic gardening if used correctly.
Severe caution: Do Not Use Neem Oil in Aquaponics! Foliar spraying Neem Oil, while helping you control the pests mentioned above could result in the death of all your fish. Why risk such?
So I was looking for an alternative foliar spray product that would not only help in controlling the pest issues but also help in providing additional nutrients and trace elements to the plants growing in our Aquaponics systems. We have been spraying Maxicorp with iron on occasions as well as Vermicompost tea with excellent results. We do not always add the worm castings directly to our media beds (we may if they are wicking beds), but prefer to use foliar spray. Why? We had read and do believe that plants absorb the beneficial aspects far quicker as a result of foliar spraying. As every sustainable urban farmer knows, Vermicompost is a wonder product in the world of agriculture. It use is increasing rapidly as the numerous benefits are being shared with each other. Here is some information as well as the source:
Castings contain: 5 times the available nitrogen, 7 times the available potash and 1 1/2 times more calcium than that found in 15 cm of good top soil. Therefore, castings are supplied with available nutrients. The nutrients are also water soluble and immediately available to plant life. You will find that most potting soils have nutrient life of 2-5 days, where worm castings will last up to 6 times as long as other types of potting soils. You will need 5 times as much potting soil to do the same job as the worm castings. So, in the long run, worm castings are much cheaper and do a much better job. Also, castings hold 2-3 times their weight in water. That means you water less and the pot will stay damper for a longer period. Worm castings will not burn your plants; unlike using any fresh raw manures (cow, horse, etc.) which can burn root systems if it is not applied properly. The advantage of using castings is the manure passes through the worms' digestive system producing rich organic plant food and a slow releasing fertilizer that allows for better growth. Kids for Landcare: Wormwatch, Education Department of South Australia, 1992, p. 35.
A worm casting (also known as worm cast or vermicast) is a biologically active mound containing thousands of bacteria, enzymes, and remnants of plant materials and animal manures that were not digested by the earthworm. The composting process continues after a worm casting has been deposited. In fact, the bacterial population of a cast is much greater than the bacterial population of either ingested soil, or the earthworm's gut. An important component of this dark mass if humus. Humus is a complicated material formed during the breakdown of organic matter. One of its components, humic acid, provides many binding sites for plant nutrients, such as calcium, iron, potassium, sulfur and phosphorus. These nutrients are stored in the humic acid molecule in a form readily available to plants, and are released when the plants require them. Mary Appelhof, Worms Eat My Garbage, 1982, p.68.
Worm Castings also contain trace minerals, such as small amounts of Phosphorus and Potassium, Iron, Calcium, Magnesium, Sulfur, Boron, Copper, Zinc and Manganese. There are two ways to obtain the solution, what we call “compost tea”, for the foliar spray. One is to brew the compost tea by merely soaking a bag of worm castings in water for some time and using this spray solution, a weak “compost tea” – the extracted method. The other, and one that I prefer, is known as the “aerobically” method.
In the brewing method, compost/castings are placed into a container of circulated and aerated water (via an air bubbler or similar system) typically with other nutrients. The circulated water extracts the microbiology and the microbes are in an abundance of both oxygen and nutrient to feed upon. In this method, colonies of microbes are brewed in exponential numbers, a colony of bacteria for instance can double in population every 20 minutes. Aerobic brewing takes longer than basic extraction with common brewing times of 12 to 24 hours. Brewing time is very dependent on water temperature with warmer water creating faster brews. Aerobically brewed teas have much higher microbe population densities than extracted teas and for this reason are the tea of choice. The sign of a good aerobically brewed tea is a good head of foam and scum on top signifying healthy microbe action! https://www.yelmworms.com/compost-tea/page3.htm
As we have increased the growing area in our Aquaponics research farm, we require an increased quantity of the aerobically brewed compost tea. This compost tea takes at least a couple of days to make and only has a limited shelf life (try use within 12 hours if possible). We have designed an Aquavermicponics system that will ensure that we will have the aerobically brewed compost tea available on hand at all times. In our system, we can also experiment by adding such wonderful natural products as Molasses, thus adding additional nutrients for excellent and robust natural plant growth. Prior to using such this incredible powerful and magical “Sahib Compost Tea”, one could add just a few drops of “hot sauce” and/or cinnamon juice extract so as to increase the potency of the solution. Do remember that you should only spray when temperatures allow and when not harmful to beneficial insects such as honey bees and lady bugs. Here are a few pictures of our Sahib’s Aquavermiponics system. We have added a media bed with a modified Affnan bell siphon so as to increase aeration.

Additional Media Beds at Sahib Aquaponics Research Farm
Adding Additional Media Beds for Increased Growing Space and Extra filtration
Adding additional media beds for increased growing space and extra filtration presented a challenge, especially when you are working with extremely limited space. I noticed that the top of our Koi pond was at present “wasted space”, just waiting to be put to use for growing additional food. I could have just built shallow water culture (SWC), raft beds as our filtration system was already adequate for our needs. However, our Koi are growing rapidly in size and I do not really want to part with them. They feed right out of my hand and provide such stress relief that it is hard to describe. With the temperature’s increasing as we enter the hurricane season, the extra feed that the Koi are enjoying, any extra filtration during these months would be extremely beneficial in keeping our Aquaponics created Ecosystem in balance. Adding media beds should help meet this need.
David Hart, my fellow Aquapon friend and I discussed what would be appropriate to build over the Koi pond that would be both functional as well as cost effective. We decided that we would replicate the Sahib Zero Lot Hybrid Aquaponics System grow beds on both sides of the fish tank. Not only would these provide us with additional growing area and the much sought after filtration, helping us use as much of the valuable fish waste within the system as possible, we would also be able to substantially increase aeration by using the modified Affnan bell siphons. We have built the first section of the media beds and they are operational, functioning just a s planned. Here are a few photos that we are sharing and a brief video of the new media beds now in operation .
Sahib is happy to share with you the endless possibilities of how to grow your own food locally and naturally without the use of harmful pesticides and chemical fertilizers by using these Aquaponics hybrid urban growing systems. These Aquaponics hybrid urban growing systems can be scaled to size and can be replicated. They can be modified to be operated off grid as well as expanded as the need arises. Such systems can be used to have fresh food at home, work or anywhere they are set up. They are excellent tools to use as teaching aids so that we can empower the future generation with the knowledge to grow their own food locally by natural means. Sahib’s Aquaponics hybrid urban growing systems can be the basis of feeding the family, the community as well as provide income to the urban farmer. Sahib will also share how such systems can be used in urban retail economy, both by food establishments as well as food/produce retail outlets to enable the consumer to purchase food that has been grown locally and by natural means. Food that is “live” (a new twist on the label “Fresh”), and the type recommended by most medical and health professionals as what we should be eating.
Sahib is using the profits from Aquaponics training workshops by Aquaponics Urban Gurus to fund the development of Aquaponics for the poor hungry world villages. He has set up a separate group for this called “Feed Hunger Now” (see link below). Will you help join Sahib…can we work together in this venture? What ideas do you have to help towards this goal?
