I have a closet about 3 feet deep and about 5 feet tall. I plan to do 3-4 plants scrogged in 5 gallon bags with organic mixture. With a part A & B organic fert. I was going to use mylar 1mil thick with mylar tape to seal it all. I plan to use 8 27 watt daylight bulbs to veg and then 8- 47 watt soft white bulbs. But this with everything is around $150. Should I just get a 250 or 400 watt Mh/HPS for the extra $50? The only problem is ducting the air, the closest window to duct out of is about 12 feet away. But I could duct the air directly into my room and then have a fan blowing air out the window. Also for the substrate since its 4 plants should i just do something like a bubble bucket or an organic mixture.
