kind of a complex question if you want it to be. safe to say that inferior greenhouses produce inferior buds. cheap, plastic- covered hoop rows that are covered up for 12 hours a night make ideal environments for powdery mildew and botrytis. at the other end of the spectrum, there are super pimp greenhouses that would outperform any comparably sized indoor grow room that just run lights. admittedly these are often "hybrid" affairs that utilize 1000 watt lamps to supplement the sun, but they are the supplement, not the staple. in theory at least the greenhouse should create the ultimate nugget, one whose life remains free of the abuses (wind, rain, low temps, high humidity are just a few)of the outdoor world. in practice, it takes smoking a ton of ganja to get to the point where you'll appreciate the difference and even then... I wouldn't turn my nose up at a strain that I had never tried but wanted to because it was grown hydro with chemicals, even though I'd prefer outdoor organic. Haha here's one for you guys that have ever sold to a club: when you show it to them, they go, "is it indoor or outdoor?" shit if you have to ask, then it's indoor! (its what everybody wants, right)?
