Organic Fertilizer for Your Cannabis Plants-Compost Tea

I pretty much stick to using organic fertilizers when growing my cannabis plants. And, my favorite is compost teas.

Compost tea is very simple to make, and your plants will love it!

Here is some I have for my outdoor plants, both cannabis…my volunteer cannabis plant…and the plants I have destined for my permaculture food forest.

This is a very simple mixture of a couple gallons of high quality, finished compost I had.

Dump it in, add water and let it sit. It gets better with age, although I will use it all in a week or so, as I am feeding quite a few plants with it.

Any additional activity going on within it would be considered anaerobic. Although, if you have alot of surface area exposed to the air, there is some uptake of oxygen going on.

I do not feed this every time I water, but for sure ever other time. It would be hard to burn plants feeding this mixture, and some of my plants can be a bit root bound so the extra nutrition is very beneficial.

I am feeding that volunteer cannabis plant copious amounts of this tea and she (yes, it is a she, as I found some preflowers) is loving it!

You could substitute about any kind of fertilizer in the mix you wanted, worm castings, manures, guanos, ect. You would just want to error on the side of too little, rather then too much, especially if what you add is considered to be ‘hot’. If you are unsure, feed only a small amount, see how the plant responds (give it 3 or 4 days) and adjust the amount you feed. It is not rocket science, but if you give your plant way too much of a good thing (fertilizer) the result can be catastrophic.

I have another batch of compost tea for my indoor seed grow.

I use an aerator for this compost tea. I do this for several reasons.

First off, the aeration keeps everything mixed, I can simply add things to it and there is no need to stir it.

Second, the aeration supplies oxygen in the water, which makes the process aerobic. This ensures many beneficial creatures (microbes, bacteria, fungi, protozoa, nematodes, ect) living in the tea, can continue to do so.

These organisms are very beneficial to your plants, and can actually help prevent disease, helps create, and maintain healthy soil, and helps immensely in your plants ability to uptake nutrients.

This tea I will use nearly every watering, as I tend to grow my indoor seed plants in small pots, as I do not need huge plants to produce an abundance of seed.

I like to use a variety of different nutrients in this tea. I do this to ensure my plants have a complete and balanced diet. I will usually add several types of fertilizers when I mix up a batch…pretty much what I have around, which right now is cliff swallow guano, compost, a package of organic fertilizer I bought at Home depot, worm castings, ect.

One of the ways I get the microbial life in high gear it to simply go out somewhere natural, (forest, wildlife area, ect) go, under a tree that has been there for years. You then scrap off the surface leaves, and what will you find underneath? Some of the best natural compost you can find anywhere, and again it is free!

I need to add here, I would choose deciduous trees (but not! heaven forbid a Black Walnut) to get your compost from under, if it were an evergreen tree the compost will likely be to acetic.

As a matter of fact allelopathic plants are more common then I thought, here is an article listing them.

Just scrap up a pile of it, take it home, and add a couple cups of it to your aerated tea. Your plants will love you for it.
