Well having fans pulling off of your light is good, but no ducting? I assume that is probably 150w since there is no ducting pulling that hot air anywhere? If you could arrange your plants to a square shape, it will allow for a more even distribution of light and save you the hassel of rotation in the future. Get some 2mm thick mylar up there, and I think this is a really good start. Mylar isn't the most pertinent thing this early, but later you will want it, and now is the easiest time to install it.

the fans are actually blowing onto the light.. theres no ducting because i dont wanna get all fancy and expensive.. with ducting i would need blower fans, with that i would need carbon filter ect... dont wanna do all that. so i put fans blowing onto the bulb, to keep it somewhat cool, i doubt its keeping it SUPER cool .. but its better than nothing imo. the 400 watt isnt even putting off alot of heat tbh. i can put my hand 6 inches under it and barely feel heat.. but up close, its real hot.
stays about 75-80 with the lights on (non digital thermo) and its about 7 feet tall(floor to roof) about 4 1/2 feet (side to side) about 2 feet (front to back)
