As far as growth enhancers go Nitrozene is okay but you've really got to try Nirvana on your plants.

It's got the same positives - it's 100% organic, kelp derived, etc. But it's takes things to a whole new level. I'm not sure what they do different but it, but that Nirvana stuff does exactly what you expect a flowering growth enhancer should do for your plants. More, bigger flowers, better flavor, the whole deal.

I actually like the results from Big Bud (also by Advanced Nutrients) better, but if you're going all organic with your plants Nirvana is the the growth enhancer you want to use.
