Worm Casting Tea Supplement

by Mary
(Redmond, OR)

I have a worm factory. It has been in use for about 3 months. Can I use these composted castings for fresh worm tea for my plants? A local dealer told me it was not a good idea because of all the bacteria, as I have an aeroponic system, and says it would kill the roots and introduce "bad" bacteria into my system.

I would like to stay with organic feeding for both the veg stage and flower stage. Also, with worm tea and sea kelp, would you need to add any other additives to enhance the flowering and fruiting stage? Thank you, Mary.



Answer: Mary- my personal opinion is that this dealer doesn't know what he is talking about. One of the main sources of nutrients found in soil is from worm castings. The micro-flora in the gut of worms adds a whole host of beneficial micro-organisms and amino acids to the soil as worms produce castings.

Plants have evolved over millions of years to flourish (in a symbiotic relationship) by using the waste products of worms and millions of beneficial micro-organisms found in the soil. Later, when the plant dies, the worms and micro-organisms consume and decompose the plant material turning it back into Nitrogen, Carbon, humic acids, and amino acids (which other plants will again use).

Beneficial micro-organisms and worms are key to producing nutrient rich compost....the living soil that is the keystone of organic gardening. Before the 1950's, every farmer was an organic farmer....it was only after WW2 that large corporations took massive chemical stockpiles used to produce munitions and began packaging and selling them as chemical fertilizers and pesticides (giving birth to "modern" agriculture).

Unfortunately, the huge profits made from the war were poured into advertising and marketing campaigns to advance this new money making venture. Fast-forward to today, many people are brainwashed and believe that you cannot grow a successful garden without chemical fertilizers and/or toxic pesticides. The truth has become so mangled and twisted that some will even claim (out of ignorance) that worm castings and compost are dangerous to use because of bacteria!

One of the biggest problems with using organic fertilizers, such as worm casting tea and compost tea, is that they are more likely to clog the spray nozzles in your aeroponic system. This can be reduced by using an in-line filter and/or pre-filter with your system. You will still need to check the system often for clogged nozzles.

While worm castings do have many beneficial qualities, they are not a complete fertilizer. Mainly, they provide Nitrogen in a form readily available to your plants (that will not burn your plants). Other items will have to be added to your tea recipe to give it acceptable levels of Phosphorus, Potassium, and all of the necessary micro-nutrients. In addition, your formula will have to change when you switch the plants from veg to flowering.

A good place to start would be to try to duplicate the recipes found in two organic products called Super Tea (pictured above) and Budswel. They are both made by the same company....Super Tea is the veg formula recipe and is made of 1 part sifted compost, 1 part high Nitrogen bat guano, 2 parts worm castings, and some soluble seaweed. It has an N-P-K of 5-5-1.

Budswel is a supplement added to the Super Tea during flowering to increase Phosphorus levels. It has an N-P-K rating of 0-7-0, which leads me to believe it is made entirely of high Phosphorus bat guano, or possibly a mix of bat and seabird guano. Using equal parts of Budswel and Super Tea make a nutritionally complete tea with adequate Phosphorus to promote flowering.

Knowing what nutritional value each ingredient "brings to the table" is important if you are tying to customize or make your own recipe. Seaweed adds a relatively complete mix of necessary micro-nutrients. As an extra benefit, it also provides some plant growth hormones. Some tea recipes are brewed for a day or two (to grow populations of beneficial micro-organisms)....in these recipes seaweed provides a source of carbohydrate upon which micro-organisms feed and multiply.

Properly made compost has a well balanced N-P-K ratio, making it a good starting point for any tea. In addition, it is loaded with the very beneficial micro-organisms you want to promote. Adding it to your tea recipe inoculates the tea with these beneficials. Plus, the micro-organisms that created the compost have loaded it with humic acids and amino acids (which is a big reason why they are beneficial).

Bat guano is loaded with minerals and is in a form immediately available to your plants, but the main reason it is used is to increase Nitrogen (with high N guano) or Phosphorus (with high P guano), making any recipe very customizable. Well composted horse or cow manure can be used in place of guano to bump up Nitrogen levels.

It is a little more difficult finding organic additives to bump up Phosphorus levels. Clean wood ash has a lot of P, but it will also change the pH of the mix quite a bit (probably too much). Bone meal has a lot of P, but in using it you risk mad cow disease (your call). Perfectly good results can be had using just compost and seaweed, but most experienced gardeners like to shoot for bigger yields by adding extra Phosphorus during flowering in some way.

So you see, mixing your own tea is both an art and a science. If you decide to try a longer brewing method (one or two days), make sure to place an air bubbler in the bucket of water (with the nutrient). Beneficials need an aerobic environment to multiply, and an anaerobic environment will only promote pathogens.

Your next big challenge will be adjusting the strength of the nutrient tea once it is made. Using a TDS meter (or EC meter) is always a good idea, but with organic nutrients it can only be used as a general guide....organic nutrients read differently than standard chemical hydroponic nutrients. In addition to a TDS meter, use a visual test....most recipes need to be diluted with plain water until a glass full looks like weak tea (the kind you drink).

Lastly, you may read all of the above advice and decide it is too much work, too complicated, or beyond your current ability. If this is the case and you still want to go organic, check out
this post, written to another visitor who had a question about using organic fertilizers in his aeroponic system. Hope this helps, and Happy Growing!

Great artical. Here's some more tips NEW
by: Jason

I enjoyed reading your artical.

I hoped you would of gone Over the right amount of power your air pump should be. My suggestion is that you can't have too much air from a strong pump like the commercial one air pump. But you can go too cheap & it end up being that it's not enough to get all the benefits that are readly availible with a stronger pump.

Most importantly. You should always have an air pump no matter what and the brewing temp should be 65 f.
The cold water allows for more oxygen to be available.

That dealer does not know what he is talking about
he could not be farther from the truth.
He must have some other product to sell.

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!
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!
