If it makes you feel better, ive had 2 friends use 1000W+ in 1 bedroom apartments with E bills around 400 a month. It's not the actual temp of room the IR picks up but basically right in middle of bulb b/c the HPS/MH burn around 2000F. I would use some IR blocker that you can get from a local indoor garden supply. If you do use it, you will need to line full room to about 1ft off of the floor. Kinda pricy but it's "supposed" to work.

1. Don't have party's or even be stupid at all.
2. Don't tell ANYONE!!!!!! Really cant express that one enough.
3. Stay as far away from trouble as possible, this would include- NO FIGHTS, NO SMOKN N DRIVIN. I mean its really common sense.
4. STAY PARANOID- It's actually good if you are aware of your surroundings and scared basically.

Im to the point where i dont even hang out with people b/c ive had experiences over the last 4 years, and learned to not TRUST NO ONE. And if you do harvest, say "IT CAME FROM A FRIEND" otherwise you defeat the whole purpose.

That's all i feel like typn on that subject, Good Growing and stay smart!

EDIT: One of my friends was HORRIBLE with security, their was 10+ people that knew about it who were sketchy, Girls, Friends friends. OMG he didnt pay his E bill for 3 months. THIS IS WORST CASE SCENARIO HERE. got cut off. Was getting a E bill for $900.00. HAHA Bottom line- i stopped hanging out with him and got him to delete my name,MSG;s and phone number from his phone. IT WAS STUPID, and hopefully he can be succesfull with it.
