I have some of this left . Can I use it In my organic grow? First organic grow and it's going great! After all it does say organic
Big Bloom is a wonderful Organic supplement. I've used for a while now, not too expensive either. I don't think you'll get any immediate noticeable results just directly using it in flower. It is not what it is meant for.
If you already have it on hand it is a great organic additive. I use it on most of my house plants as well. When you run out, instead of restocking, consider investing in a small worm composting bin to produce worm castings. Worm castings are a key component of Big Bloom, and you'll find that red wigglers will produce a ton of organic castings that can easily be mixed in with most soil-based grows. For use in a hydro setup, it would be necessary to either collect the "tea" runoff or encase the castings in cheesecloth and dunk.
