Organic Fertilizers in an Aeroponics System

by Mack

Is it possible to use an aeroponic system with organic fertilizers?

Answer: Yes, it is possible to use organic fertilizers in an aeroponic system, especially one that does not use the spray heads with the very tiny holes. Organic fertilizers tend to have more particulate matter in them, and they usually end up clogging the tiny holes in the spray heads of high pressure aeroponic systems.

Using an in-line filter made just for hydroponic/aeroponic systems, you can greatly reduce the problem with clogged spray nozzles if you decide to go with a high pressure system. Alternative Garden Supply has one, I believe they call it an israeli filter. Just make sure the filter you use is appropriate for they type of system you choose to use (high pressure or low pressure). Also, you will want to clean your filter often so you do not burn out your pump, which will happen if it is fighting to get water through a filter clogged with gunk.

Most of the aeroponic systems I write about on my website are low pressure systems, which makes the whole problem of clogged spray heads a non-issue. In fact, with most of the low pressure systems you probably won't even need to have a filter! Check some of them out here: aeroponic systems.

I don't know if you have your fertilizer plans all figured out, but the commercial hydroponic industry has come up with a couple of good organic hydroponic fertilizer programs.... below are the products and the recipes....

For vegetative growth:
126 ml Cal-Mag Plus
180 ml Liquid Karma
540 ml Pure Blend Pro Vegetative Formula

For flowering:
126 ml Cal-Mag Plus
150 ml Sweet
180 ml Liquid Karma
540 ml Pure Blend Pro Bloom Formula

The guy I know who uses this formula mixes all of the ingredients together, than adds them to his nutrient reservoir a little at a time until he gets the nutrient strength where he wants it. For the record, DO NOT mix normal hydroponic nutrients together in this way....they will chemically combine to each other and lock out all of the nutrients (that's why they come in two separate bottles).

Another organic fertilizer to consider would be the Canna Bio line. There is a Veg formula (Bio Vega) and a Flower formula (Bio Flores), and they are both one-part fertilizer systems! To make matters even more convenient, these nutrients are just the right pH, so you won't have to check the pH every time you check the nutrient strength (and you won't have to buy any products to adjust the pH either). Also, the fertilizers contain NO animal products, which will make you very happy if you are a vegan, lol.

And just in case you are not very familiar with how you should be maintaining your nutrient reservoir, be sure to read my hydroponic nutrients page. Good Luck!

Do you mean don't put them in at the same time? I am a dumb when it comes to this kind of thing. Do I just wait a few hours then add the rest?

Added Response: You can add the hydroponic nutrients to your reservoir (full of water) at the same time, but you should NEVER mix full strength nutrients with each other before putting them in the water. At full strength, they will tend to chemically combine to one another, locking the nutrients out and doing your plants no good.

We use only Organic Liquid Fertilizer in our Aeroponic System
by: Gardens on Air

We firmly agree. We are currently using a low pressure tower aeroponic system for our crops, and other than the initial cleaning out of the jets when the system first became operational, I have had no other issues with clogging.

Find out the cheapest and easiest ways to garden productively in this article.

Hi everyone, Jason from Jason's Indoor Guide here. When I got started with hydroponic gardening more than 24 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...

Epic Nutrient Change

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 24 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)...

Homemade Cloner

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 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.

Unfortunately, I have been gardening for over 24 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! If you can master the technique, 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...

High Efficiency

The ultimate 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! Plus, at the end of the gardening cycle you harvest all of your garden vegetables, PLUS YOU HARVEST FISH from the system--->

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 24 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!
