Works out just fine that way. You can also do teas or some flower boosters just fine if thats your thing. It came from pureknowledge, if i recall he added a few floral boosters is all but water base. I started running it just water only and never had issues once with fresh mix. It was designed to tease out maximum growth from slow vegging sour bubble, the texture is really nice and shit explodes in it.
U let that compost for a few weeks or mix and throw um right in? mixing my own soil works great for me outside but indoor seems like a pain, coco seems so much easier and cleaner.
