That's the same line that I just used on my last grow, and my next grow! Love BMO Products. I am using BMO line, Molasses, & Alaska MorBloom as a flower booster. The shit stinks (the cats love it) but the plants seem to love it!
I only veg for about 16 days (from seed) until I throw into flower, because I like my plants short. I use the Grow once, then switch to a mixture of Grow & Flower about 1 1/2 weeks into flower. The plants loved it! They actually showed sex WAY before any of my other plants. Then I just let off the Grow, and went with the straight Flower for a couple weeks. Then when they were really budding like crazy, I cranked on the MorBloom. Start with small doses then work your way up, esp with the MorBloom. That shit is POTENT! I just harvest my C99 and now I'm gonna be harvesting Arjan's Haze #1 this week.
