@ThreeLittleBirdsCC, thanks dude! I mix the BioGrow and BioBloom directly in the substrate. GHF recommend 3-5g/ltr substrate of each - since I only grew autos until now, I've always used 1/4 dose. I also throw in some other organic nutrients like worm castings and bat guano. During the grow, I feed BioEnhancer (media drench) once every 2 weeks, starting on the 7th day after seed sprouts. Again I use 1/4 dose of the recommended 0.5-1 g/ltr water. Other than that I only water like every 2-3 days.
