First timer needs setup help!

I'm a first time grower, and I'm working with a space aprox. 3.5 x3.5 and just under 7' ceiling.

I understand I'll need intake and exhaust ventilation and I'm working that out now. I'm getting ready to order a hps light and need to know how much light I can get away with in this space, without causing excessive heat. I would like to try and avoid using cooltube reflectors if possible to keep costs down. Can I get away with using a 600 watt light? Or would a 400 watt be more appropriate?

Really appreciate you helping a new grower out, I'll be watching for your advice.

Thanks

Anyone have any ideas?

Should this post be in the newbie forum instead?

What's it take to get a little help here? C'mon help a brother out!

Being new at this makes it tough for me to know how much heat these hps lamps will produce.

Well that depends on how good your intake and exhaust is

Chill out bro, people will help, just be patient. A 600 with a curved aluminum reflector should be fine in that sized space with proper ventilation. I personally like the Osram Plantastar bulbs, they put out 90,000 lm and have 20% blue spectrum. Just my $0.02

if your hood is sealed off and seperatly exusted you could get away with a 600, but im working in close conditions to you and i have a 400w M.H and i am thinking this will still produce too much heat because the hood isnt sealed off but im planing on hooking up seperate ventenlation , do have any ideas on how to do that without having two carbon filters
