400W vs. 1000W HPS lighting

**lakshyt** · 10-12-2006, 03:22 PM

hello

i am planning on growing in one of my apartments closets

i am going to use a drip hydroponic system

the closets dimensions are 2' x 4' x' 5'

now, i wanted to get a 400W HPS ballast and bulb... but i found a great deal with a 1000W ballast that works and comes with an HPS and MH bulbs...

so i was wondering if it would be okay to run that 1000W light system for this small closet that will have a maximum of 10 trees...

thanks alot for any help

Hi LAK.. like the gents are saying...

If you can pull the heat away then YES get a 1000 watt bulb..

It is no use to get a 1000 watt bulb if you will have to keep it 3 feet away because it is so darn hot.. then you should just go with the 400.. BUT if you can pull the heat from your light/hood out of the room.. and get the bulb 10-20 inches from your plants.. then you will be one HAPPY camper.. your BUDS/colas will be the size of forearms..

I would stay away from the 1000 w system! To much lighting for such a little area. Go with 400 w. You will most likely need at least 765 cfm or better exhaust for such a small area. I tried to grow a plant in an area about that size (my shower). 1000w was to much light and killed the plant due to over lighting. But the 400w was perfect, but still dealt with heat issues. Now I have dedicated half my basement to grow my stuff! Don't know why I didn't do that in the first place (to big a joint ~ lol). Can't you use a bedroom?
