Organic Hydroponics Feeding Tips

My number one organic hydroponic tip is this- pick a hydroponic system that does NOT use drip heads or spray nozzles. If you need to know, in general, how to mix up your nutrients and how to maintain your nutrient solution properly, that information is found over here-> hydroponics feeding tips.

A Good Place to Begin

A cheap alternative to expensive 3 part hydroponic nutrients. It is seaweed based, so it has all necessary trace (micro) nutrients, as well as some plant hormones! This is the bloom formula

One organic hydroponics feeding plan I found is simple, works very well, and is less expensive than professional hydroponics fertilizers (which are usually not organic, anyway). The plan is to use Maxsea, a seaweed based fertilizer that is affordable and relatively complete. For the first 7 days the plants have roots, I usually give them 400-500 ppm Maxsea 3-20-20, which is about one rounded teaspoon in a gallon of water. The extra Phosphorus is what really young plants are looking for to feed new root growth.

I first heard about Maxsea fertilizer from a High Times article back in 1994. It talked about Emily's garden, a closet DWC system, where she used Maxsea and Epsom salts instead of hydroponic nutrients

After this point, the higher nitrogen levels will no longer damage the young plants, so I make the solution about 700-800 ppm Maxsea 16-16-16. This is about two level teaspoons in one gallon of water. When the plants are switched to flowering, I use a 50/50 mix of Maxsea 16-16-16 and Maxsea 3-20-20 for the first two weeks (it takes about two weeks for the plants to adjust and fully transition into flowering).

I used to use only the Maxsea 3-20-20, but the plants usually ended up a little nitrogen deficient before the end of flowering. The 50/50 mix at transition helps to keep a little more Nitrogen in the game till the very end of flowering. I try to keep the solution around 800 to 900 ppm during the transition period into flowering.

It is extremely important to know how strong or how weak your nutrient solution is before feeding it to your plants. A cheap TDS meter (or EC meter) really is your best friend!

Finally, I switch to plain Maxsea 3-20-20 to finish (except for the flush, of course). I keep the solution around 1000 ppm, which is about 3 level teaspoons in a gallon of water. It is always best to us a TDS meter or EC meter to check your nutrient strength! I have very detailed information on how to maintain your nutrient solution properly from day to day over here.

Flushing a crop with plain water before harvest will improve the aroma and flavor of your produce. In a hydroponic system, this can be done with 7 days of plain water. It is helpful if you change the plain water with fresh water every day for these last days, but it is not absolutely necessary (and I don't). I DO, however, like to add a little Thrive Alive B1 and Liquid Karma to my "plain" water while flushing. They are a little different than nutrients-> They continue to drive cell division in the plant and help a great deal with the flavor of the plant, and especially in the resin production of the plant.

These Epsom salts have no perfumes, no dyes, and are very affordable - over at Amazon

The only thing about Maxsea is that it is missing magnesium. Add 1/4 teaspoon Epsom salts to every gallon of nutrient solution and you will never have a problem with this.


The Benefits of Maxsea

Cheap and effective - and you really can't do without it unless you want to screw things up!

Using Maxsea for organic hydroponics is great. It dissolves almost completely, with very little particulate matter, so there is less stress on your pumps. When you mix it up, it is nearly the perfect pH. This eliminates the need to purchase an expensive pH meter in the beginning (I still recommend getting a pH drop test kit- it's cheap).

Aside from being easier to check and correct for pH, Maxsea is a complete fertilizer (except for Magnesium). This also makes your feeding much more simple than it could be. Just be sure to include 1/4 tsp Epsom salts to every gallon of nutrient solution you mix up to include your Magnesium, and your good!

Because it is a seaweed based fertilizer, you do not need to supplement with liquid seaweed for trace nutrients. Seaweed is also high in plant hormones, eliminating the need to supplement for plant hormones in any way.

I have seen very few other systems this simple that produce top notch results like Maxsea does. Did I mention that it costs you less than professional hydroponic fertilizers? One of the only places I have been able to find the Maxsea fertilizers is Charley's Greenhouse and Garden. 2016 Update: they have it on Amazon too : )


Other Organic Feeding Options

3 part hydroponic nutrients are usually chemical based. They probably have all the necessary trace nutrients, but they DON'T have any plant hormones, making the addition of liquid seaweed a great idea

Another popular feeding method when using organic hydroponics is to make a nutrient tea from worm castings and bat guano. You may want to add Maxicrop liquid seaweed and Thrive Alive B1 at 10 ml/gallon to add hormones and vitamins to the mix. These are two of the very best nutrient additives you can you can include, no matter what base nutrients you decide to go with.

I use it in every drop of water start to finish, including the flush. B1 fuels cell division, drives fast plant growth, lessens transplant shock, and helps with resin production in the last 10 days

For the vegetative stage, put two parts worm castings to one part high nitrogen bat guano to make your tea.

For the flowering stage, use one part worm castings to two parts high phosphorus bat guano to make your tea.

Place the organics in a sock or pillow case and make your tea in 3 to 5 gallons of water. Again, a TDS or EC meter is very helpful to tell how strong the nutrient solution is. Organics mixed in this way will seem to turn out a different strength every time.

Pictured here- high Nitrogen bat guano from HydroFarm

Before you use the tea, determine how strong the nutrient solution SHOULD be, based on the stage of your plants life cycle. The tea will likely be stronger than you need. Simply add plain water until the solution is just the right strength.

Last, make sure you check and adjust nutrient solution to a pH of 6.0-6.2 before using.


Organic Hydroponics with Canna Bio

Organic and vegan in fact! The Canna-Bio line of nutrients are also one part nutrients. This makes them extremely friendly for beginners to use. Pictured here is the flowering formula

Recently, two other "professional" organic feeding options have come to my attention. The first one is the Canna Bio line of nutrients. With Canna Bio, there is one fertilizer for the vegetative stage and one for the flowering stage. Not only are these fertilizers organic, they are vegan (they contain no animal products). Plus, they are one part fertilizers, which is unusual....most hydroponic fertilizers come in two or three parts that need to be mixed into solution. This makes them convenient to use, especially for those who are a little intimidated with mixing two or three part formulas.

One part organic (hydroponic) veg formula

These fertilizers also mix up at just the right pH, which is a great benefit. This makes it easier to maintain your nutrient solution every day. Instead of checking the nutrient strength (and adjusting it) than checking the pH (and adjusting it), with Canna Bio products you only need to check and adjust the strength of the solution.

When you don't have to check the pH of the nutrient solution all the time, you save money in two ways. First, you won't need to buy an expensive pH meter for checking the nutrient solution every day. Second, you won't need to buy pH UP or pH DOWN products to adjust the pH as often. When you add up all of the benefits, Canna Bio becomes a very friendly fertilizer to use (especially for beginners).


Organic Hydroponics with Pure Blend Pro

In the grow stage, Pure Blend Pro can be used as a one part fertilizer. When flowering, I highly recommend you use it in combination with Cal-Mag (and any other supplements you prefer)

The second "professional" quality organic hydroponic fertilizer plan I have come across recently is a recipe (actually two) using Pure Blend Pro as the major nutrient. You should use this feeding plan only if you are comfortable with mixing up a three part nutrient solution, and if you are comfortable with checking and adjusting the nutrient strength AND pH every day (basic stuff, but it can be intimidating to a beginner).

For the vegetative stage use:

126 ml Cal-Mag Plus
180 ml Liquid Karma
540 ml Pure Blend Pro Vegetative Formula

For the flowering stage use:

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

Heavily flowering plants are often limited by the amounts of Calcium present. Magnesium needs to be present in order for Calcium to be used efficiently

The person I know who uses this formula mixes all of the ingredients in an empty milk jug, than adds the mixture slowly to the water in his nutrient reservoir until he reaches the desired nutrient solution strength. He than adjusts the pH to 5.8, which works very well for this formula.

Very similar to Liquid Karma- contains sugars (carbohydrates), amino acids, plant alcohols, esters, and humic acids. I use products like this throughout flowering, but especially during the flush

It's important to note, you should NEVER mix normal hydroponic nutrients together in this way before adding them to the nutrient reservoir. If you mix chemical hydroponic nutrients together, they will chemically combine and will be useless to your plants as food....that is why they are bottled separately in two or three part formulas to begin with! When mixed into a nutrient reservoir full of water one at a time, this chemical interaction is not a big problem.

Liquid Karma is one of my favorite additives. Using products like Liquid Karma during the flush helps your plants develop their resin profile. End result: tastes like it's grown organically in soil!

My friend has never noticed any problems from mixing together his nutrients in this way. The only reason for this, I guess, is that the nutrients are organic nutrients and not simply a positive(+) chemical ion and a negative(-) chemical ion that would join together as soon as they are mixed.


Picking an Organic
Hydroponics System

The only difference between hydroponics and organic hydroponics is what you choose to feed your plants. However, there are some hydroponic systems that do not work well with organic hydroponics. Even organics with very few particles floating around will still clog drip emitters and spray heads. For this reason I do not recommend hydroponic drip systems or aeroponic systems.

Hi everyone, Jason from Jason's Indoor Guide here. When I got started with hydroponic gardening more than 20 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!

What is colloidal humus?

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.


High Efficiency
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!
