I was so impressed with bloombastic I switched all my nutrients over to B'cuzz the same company that makes Bloombastic. It's the first time I've seen a grow product do what it say's it's going to do. If you google Ask Erwin with Atami they might just give you a sample of Bloombastic. That's how I started using it. You can't complain about prices when the stuff works that good. More weight, More resin. It's really good stuff.
