X2 with blessed! I do have a few bottles of terpinator that I have never used. I have a smidge of Bud Factor X left and I love that stuff too. I ran the Bud Factor X along side the Snow Storm and loved both results. I would suggest to find one of the 3 and get what ever is cheaper. A note on the Snow Storm, I run it with a product called Sugaree, which is an organic carbohydrate and both together, really make the plant drink when mixed together. If you run them both together, Keep a close eye on them, like daily of you run the risk of opening a droopy tent!! Uptake is phenominal with those two!!
