New 400watt HPS grow!

this is a set up im looking at b/c it is pretty well priced and since im using just 26watt cfl's through my flowering i could def. use this.
Could some of yall check it out and see what yall think and maybe tell me anything i should know about these lights set ups in a small area grow( like a closet)

+reps to any help

HTG is really good IMO if you're on a budget. I've got the 150HPS which has the exact same reflector you're looking at. It's obviously what you'd expect.. it gets the job done but it's thin and I had one clip on it break off from little use. (Basically you can adjust the reflector by bending it but the clips that hold it together are really thin and will break after bending back and forth a few times. Nothing duct tape doesn't fix though.) Anyhow, the light/ballast itself is solid and HTG is a great company to buy from. Worst case you can always replace the reflector but you shouldn't need to. I'd go for it. Good luck!

anybody else out there that could give me some information on this?
Like would i have to have any ventalation for the 250watt or even the 400watt hps since i am a closet grower.

It all depends man. Best is to read up on things, install the best system you can get, turn the light on a see what your temperature/humidity is. Then you will be in a better place to ask questions about how to alter the environment of your grow.

thats what i bought but i got the Mh bulb 179 dollar complete HTG supply is really good.
