I joined MP about a month ago,and am getting ready for my first grow. I planned everything out, but did nothing until this week because I was worried about getting my seeds, they arrived last week and now its full steam ahead. I have a a closet that is 48wx21dx72 tall, i have linned it with mylar and have a 100 cfm fan in the top vented to the outside. (cutting a hole into my house was freaky) I will be using a 400W MH bulb for veg. and a 400W HPS for flowering(Light arriving wednesday) I have a couple of questions.. in such a small area, do I need another fan to move the air inside? or is the exhaust fan enough. Putting up the mylar was harder than I thought... does it need to be absoultley smooth? this whole nute thing is freaking me out. How Many plants can I grow in this area? I have 12 fem seeds, should I try to germinate them all, or just half. I am sure all of these questions have been answered in this forum, but I have done so much reading in the last month my brain hurts.
