I've used it several times, and its the one product from that manufacturer that you can tell its doing what it said it would. If you've vegged your babes to the height and profile you want then you want to flower right away, instead of spend the next two weeks of transition vegging/flowering at the same time, it will help them bush out and make bud sites. They will stretch a little bit any ways, but you can tell its dramatically reduced if youve worked with the strain before without bushmaster. Apply it during the first week of transition, maybe even before, I've been playing around with it, just make sure you veg plenty. I've sprayed and watered, I've seen the best results when watered, each strain reacts differently, sativa's seem to be more affected by it from what I've seen.
