Personally, and this is just IMO

You're on track with the 400w HPS. In my first one or two grows i went the 400w HPS and loved it.
A 400 doesnt generate THAT much heat that it's a worry, but it's a good amount of watts for a closet.

Thats just my 2cents

Good luck! kick ass hobby you've chosen :dance:

fingers Reviewed by fingers on . Lighting Suggestions??? Hey all! I'm setting up my first grow room now. I have a nice sized closet that I'm workin with....3 x 3.5 x 5.5 (effective grow height since there is a big shelf). I've decided on two plants max since these will be strictly for personal use. I've lined the closet with emergency blankets (mylar baby!). So, here's the question: what kind of lighting should I be going for? Will one 400W HPS be sufficient for veg and flower? Should I be using CFLs for veg and switch to the HPS for flower? What Rating: 5
