I have a closet that i plan on putting a hps light in, the dimensions are 2.95ft wide, 1.57ft deep, 5.24 feet high. My ? is what size light should i get, a 250w or a 400w. From a lot of the posts i have read i think i will be safe getting a 400w, any help would be greatly appreciated.

go with the 400w unless you only plan on growing 1 plant.

400 watt should do ok in that space.

I concur, 400 should be fine, I mean you are gonna have some heat issues, put the ballast outside the closet if you can, that has helped me alot. I have roughly the same size closet. 4x2x6.

yeah heat issues like you wont believe! i remember my closet with just 250w hps, god damn it got like 90+ degrees.

i am planing on doing SOG and hopefully have about 9 small plants so i think i will go with the 400w hps, I understand i will have heat issues so what type of fan should i go with that is cheap and will last. In my cfl grow i only have 2 80mm 29cfm PC fans and the temps in that box are max 30 degrees celsius.
p.s. the grow is for personal use

How are you going to cool the room down, its one thing to say I know I am going to have heat issues its another thing to be prepared to fix it. Maybe you want to get a cool tube or put an air conditioner in the room that has the grow closet in it. I not trying to be harsh at all I just don't want you to be screwed with heat because you haven't a solid plan to reduce it. I run two 400 watters each is it own 3ft by 2ft by eight ft grow closet, I have a widow air conditioner that when set on low keeps the room about 70 degrees. I had major heat issues only running one 400 watter before putting in the a/c.

I also have a 400w HPS for closet grow. I DID NOT put my ballast in the closet, but on a board right outside. They do tend to get a little hot, (The ballast) so be careful. 400w is plenty for your grow. Worked great for me! Also, a regular roatating fan is plenty, however, moniter your heat. Very important. I actually left the closet doors open a bit for cool air.

yeah i really think you're underestimating how hot it gets. if it gets hot, stress for the plants, causing them to go male.

at the moment i plan on having an ice box connected to the passive intake. i will only be flowering through the night which gets as cold as 2 deg celsius, an aircon sounds like it would be the best bet thou. what type of air con should i be looking for.
