i am tryin to grow under my house but am not sure about the temperature because its going to start dropping does anyone think there is a possibility of this working maybe if i put a stand up heater down there? I am using a 400w hps so i figured i would grow about six plants...i have white widow seeds, just waiting on the ballast to arrive at my house.

I don't see why a heater wouldn't work. What kind of temps are you talkin?

what exactly do you mean by under your house? like in a basement?

IF its out of the wind, it doesn't matter, you can set it up to control heat. You'll probably have to make, in basic terms, a grow box if you're talking being in the ground. If you're in a trailer home, mod home, pre fab and you're just doing it on ground level, you'll def need a grow box and a way to keep it warm when the lights go out, so a themostat will surely be needed.

I always have thought about it but never tried. good luck

If you use a gas heater it also release co2, its easier to keep somewhere warm than it is trying to keep it cool. You by a electric heater on a thermostat for the night and during the day the light will keep it warm.

yes it is on ground level and i live in a modular home it has a wooden door about 3ft tall to go under my house its the only place i can grow and not get caught, i will put some pics up to give you guys a better idea...

Get a grow box that wil fit down there and just grow out of there.

thats the problem i only have 5ft of clearance and worried that i wont be able to grow the plants to full strength

you can def train plants to keep a low growing profile...LST'ing, FIM, SCROG, Topping, Super Cropping, etc,.
But just keep the plants at ideal distance from your 400 watt'r.
