They are really good, but I strongly suggest using the flower additives to get fatter buds. The two part basic isn't enough to make the buds fat but it makes them glisten, sweet and delicious.
I've never used them but after all the good i have heard about them ill be using them this season. Deff get the 3 part with the bloom boost, you can get 3 bottles for under 40 bucks and its well worth it! peace.
