• So I just cleaned all the waste from my fish tank and made a concentrate with it now. I know it’s really good to use for my plants, but I was wondering if I use this, do I have to use any other nutrients along with it or should I only hit it with this every so many feedings?

      • Growing with fish poo is totally possible. Different food sources for the fish will provide different minerals. Knowing what to feed the fish will provide your plants with the right ratio of minerals for the different stages of the plant’s growth cycle. If you don’t know what’s exactly in the fish food, I’d dilute the concentrate quite a bit and use a little as a supplement on a test plant during the vegetative stage to see how it responds. I wouldn’t trust the mineral ratios are correct to rely solely on it as complete nutrition.
