I have been using Alliance Biologics for about a year, and apply it for all phases of growth. Since using Alliance, we have seen an increase of overall root mass in our plants, a shortened vegetative growth period, and a much healthier and successful bloom. With all of this being said, Alliance has allowed us to obtain consistent 3+ lb per lamp yields, and has even helped us squeeze in an extra harvest each year due to the shortened veg period. I highly recommend Alliance Biologics to any cultivator, and have permanently made it a part of my feeding schedule.
