Ive heard good things. I used bloombastic but I would like to try it again with a better veg and better setup. Great on tomatoes I got a big tasty yield
I use Bloombastic and have had good results, but two grows ago I switched to AN Big Bud since it was a little cheaper, I use less, and I am seeing similar if not the same results. They are similar in that they are used weeks 2 through 4 of flowering.
