I find everyone worries about nutrients. Your room temperature/humidity and lighting should be your main concern. Its funny I use to have to feed my plants nutrients every watering. I have switched to organic and seem only to have to feed my plants once or twice a week now and they look better than ever
Nice to see people with basic reading comprehension skills.
How's he going to control temperature/humidity and lighting in an outdoor grow, genius?
Like the guy suggesting Peters or Flora series. Apples to frikkin' oranges. Heavy Harvest is a time-release fertilizer specifically developed for the cultivation of cannabis in situations where you can't fawn over your plants every day (guerrilla growing). It works nice for growing in soil even if you can tend your plants every day, as that's one less thing to worry about.
Jaycal - check out BrownDirtGrower. That guy knows his shit and he uses HH so it's a good way to see how it's done. If you decide that's the way you'd like to go, go for it and don't let any haters tell you different. Come harvest time you'll be the one with the last laugh.
