400 watt HPS for cab?

[keeko]

Hey, I am thinking about putting a 250w HID into a grow cab where ventilation may be an issue. The cab will only be big enough for 4-6 plants. Is this going to cook my plants or is it a low enough wattage? I might be able to get my hands on a 150 watt HID. Should I use that instead?

any light will cook your plants if you dont have the right ventilation.......weather it be 250hps, 150 hps or some clfs. cool air in, hot air out.
