I've been using the same line in liquid formula for about a year and I couldn't be more pleased but of course they've change the name to cultivation nation. Same stuff, I just haven't tried the powder formula. My last harvest with Gringo Rhasta line, using the whole feeding schedule.
Gorilla Bomb, Jack Herer, white widow. I've used the rhasta line 3 times. Using the full schedule and added epsom salt and humbolts secret flower stacker. I think a lot of people missed the boat with Fox Farms because they don't use the full schedule and they just use 3 bottle schedule. I want to try some nectar for the gods. They'll send you their beginner line which is 6 or 7 quart bottles and all you have to do is pay shipping. I've got a couple emails from them I'm gonna send the money and try it out.
