closet + HPS

hello.some1 told me that if i use HPS in 400w in my wooden closet i will burn for sure my plants.this is my first grow and i inted to use HPS 400w for flowering.i need some advice to avoid this state.i will use simple refletor 4 xblak case fans 120mm and an inside big fan.my closet is 90x90x2m.any advice will be useful.thank y in advance.

If you can get rid of the heat, and provide lots of fresh moving air, I don't see a problem.

Just keep the air condtitioner in the 70's with a fan and you'll be fine. I grow in my closet with an HPS as well.

You need to really make sure you can move the air out of the tent effectively. I went with a 400w mh/hps in a 3x2x5 tent and had to move to a cooltube and 4" inline fan to finally get my temps to low 80s high 70s. Just don't get a 400w expecting computer fans to keep the area cool. Good luck.

I have a 600w in my closet thats 5x2x8 and even though I have an air cooled hood I have no exhaust fan running through it, just a few oscillating fans and my temps are staying at a steady 79 with my door open

yeah fans its not good enought.u got any suggestion with what i really need about ventilation system?any info will be helpfull
