i've completed grows and thrown the soil into a heap in the yard and had beans that had failed pop up the following year...It may even take up to 1 week for sprout.
I used 24 7 myself but you might want to go to the growfaq or start your own thread so as not to highjack someone elses.once sprouted, how much light should be given? I just have one plant, and I have a fluorescent bulb on it right now. My one seed just poked its head above ground, and I was wondering if I should have my light on 24/7 or should I run a 12/12. Any advice?
