Preventing Plants from Sitting in the Hydroponic System Water

by Bob
(Bristol)

I have a NFT hydroponic system. I can't seem to find away to stop the plug (in which I started the seed off in) from sitting in the flow of water. Please can you help? Bob.




Answer: Bob- Some moisture in the transplant plug is usually desirable to prevent the roots in the plug from dying. However, some plants do not like to be fully submerged in standing water. Depending on how deep the nutrient solution is in the channels of your hydroponic system, you have a few different possible solutions.

One idea is to use very small netted pots. The strategy here is to place a seed (or clone) into the transplant plug, then to place the plug directly into a netted pot just big enough to hold the transplant plug. You want to do all of this before your seed (or clone) grows any roots. Once you see the first sign of roots, you want to place the netted pots into your hydroponic system. Ideally, the very bottom of the plug come into contact with the nutrient solution just a little bit. This allows the plug to "wick up" the moisture it needs until it can grow roots down into the bottom of your channels.

Another strategy is similar to above, except the plugs are suspended an inch or more above the nutrient solution (usually because of the design of the system). In this case, you may want to consider adding a drip system. This will provide enough moisture to each transplant plug until your plants have the opportunity to grow roots down into your system.

If the nutrient solution is shallow (about 1/2- 1 inch deep) you may want to consider anchoring your transplant plugs into 3" netted pots with a few clay pellets, then sitting the netted pots down into the channels of your hydroponic system. In this strategy, the netted pots sit right down on the bottom, but the re-circulating water is very shallow and therefore stays well oxygenated. The pots also can wick up the moisture they need until they can grow roots down into the system. With a little modification to your system, the netted pots can even be lifted out of the standing water and suspended above the nutrient solution once there is significant root growth.

Lastly, many plants will tolerate being grown straight in standing water. Even plants that prefer fast draining soil will grow well in these conditions, as long as an effort is made to keep the nutrient solution well oxygenated and to keep the temperature of the nutrient solution between 68 and 72 degrees. This is true with
my most successful hydroponic system. The whole strategy can be found at the link above, and the system works very well with tomatoes, peppers, lettuce, herbs, spinach, and many other plants. I hope this helps you out Bob, and Happy Growing!

Hi everyone, Jason from Jason's Indoor Guide here. When I got started with hydroponic gardening more than 22 years ago, my first garden used rockwool cubes and B.C. Nutrients....and I remember thinking to myself yeah, sure, there may be a lot of advantages to gardening with hydroponics, for example there are very few pest problems, therefore very little pest control, no weeding, no plowing or tilling the soil, no soil testing or having to add things into the garden soil, no watering the garden....but for someone who just wants to grow their own vegetables and have more control over their food supply and the quality of the food that they eat, the cost of constantly having to buy grow media and hydroponic nutrients makes this an expensive hobby for most people.

I suppose when you take into consideration how much money you save NOT having to buy food at the grocery store, it is surely cheaper to grow your own food hydroponically even with the cost of high quality nutrients. Nevertheless, I didn't have a whole lot of money to work with and I needed to make my efforts as affordable and effective as possible....and in the last 20 years I HAVE learned a thing or two!

As you browse through Jason's Indoor Guide, you will notice all of the systems that I use personally are homemade systems. As I got 3 or 4 years of experience under my belt, I quickly adopted a preference to standing water systems and systems that use expanded clay pellets or lava rock, because the media is re-usable and it eliminates a huge operating expense. So once a hydroponic system is built, garden maintenance is minimal- check and adjust the nutrient solution daily, and to change it completely every 2 weeks....and the biggest operating cost is the hydroponic nutrients. (and the electric bill, lol).

And, regarding the cost of the nutrients....I experimented for about 3 years with making different compost teas and nutrient teas, but there is still a lot of expense $$$ associated with making high quality nutrient teas....like kelp meal, liquid seaweed, rock dust, bat guano, un-sulfured molasses, worm castings. You can eliminate a lot of this expense by becoming an expert at making high-quality colloidal humus compost, and use your properly made compost as the basis of your hydroponic nutrient solution.



Make a year's worth of compost in one week!

Make the world's best compost


Unfortunately, I have been gardening for over 20 years and I have only just recently mastered this difficult skill....and even then, only because I happened to find a very easy to follow, high quality technique and decided to follow the instructions to the letter. I produced more high quality compost in just one week than I was able to use in a whole year! I highly recommend it. It is one of the top 3 things you can do to increase the productivity of your food production efforts, while at the same time decreasing the amount of effort required to grow all of your own food, and decreasing the total cost of operating your food production system.

And when I say decrease operating costs, I mean decrease them to almost ZERO, especially if you are producing your own nutrients.

Hydroponics

One final solution to eliminate the cost of your hydroponic nutrients: Imagine a hydroponic system that does not require you to buy any nutrients, does not require you to make your own compost, and does not require you to brew your own nutrient tea. Seriously! No cost and no effort as far as providing nutrients to your plants is concerned. Plus, at the end of the gardening cycle, you harvest all of your garden vegetables, PLUS YOU HARVEST FISH from the system!


Aquaponics

This solution is aquaponics. If you are serious about producing all of your own food and being self-sufficient, this is the ultimate solution for reducing expenses (as much as possible), reducing the total amount of work required, and maximizing the productivity of your gardening efforts. I have been gardening for over 20 years, and it is the perfect food production solution in my opinion.


Produce garnden vegetables AND fish together. Eliminate fertilizer costs!

Besides mastering how to make high quality compost, learning aquaponics is one of the top 3 things you can do to increase your garden productivity, reduce your total costs, and reduce your total work. The product that I learned from is called Aquaponics4you. With all of my hydroponic gardening experience, the first time I came across the Aquaponics4you product I knew immediately that it was something very special! Place an aquaponics system outdoors and use the sun instead of grow lights, and you have reduced every garden expense to nearly ZERO!


High Efficiency
Soil Gardening

This is where my advice ends for people growing in water. But some of you out there are in love with soil gardening and organic gardening, and rightly so! It's a pro-human activity. It is pro-conservation. It is pro-life. It nurtures and promotes life at all levels, from the micro-organisms to beneficial insects, to healthy humans. It's natural. it's spiritual. Gardening is written deeply into our DNA, like how you feel watching a bonfire or sitting by the ocean or next to a river.

My friend John at Food4Wealth has more than 20 years experience organic gardening, so he reminds me a lot of myself. He knows organic gardening like I know hydroponic gardening, and over the years he has learned just about every trick there is to organic gardening. He knows what makes the plants grow, and he knows how to do it with as little effort as humanly possible. His garden never needs digging, naturally repels pests, has no weeds, always produces more than his family is able to eat, produces vegetables everyday all year round, and....only requires 8 HOURS of light, easy effort PER YEAR!


Low effort organic gardening!

Years and years of experience and results can't be argued with....the Food4Wealth gardening strategy is one of the top 3 things you can do to increase your productivity, reduce your total costs, and reduce your total work....specifically for organic gardeners who love soil gardening. THIS is the most efficient and productive way to do organic gardening, period! And combined with the ability to make a years' worth of colloidal humus compost in just one week (see World's Best Compost), this overall organic soil gardening strategy is just unstoppable- foolproof, low cost, and low effort!
