Easy and cheap way to a winter stealth attic grow

My cabinet got nixed after my last grow got stinky so I had to resort to the attic. I knew my only chance was a winter grow because temps are way too hot in all other seasons here in Kansas. I found that my setup is much simpler in the cold. I have a 250watt HPS for light and a heat source. My vent fan is wired to an attic fan thermostat switch that I found at Cheap Homo for $15. The exhaust fan kicks on when the temps get to my dialed in setpoint and draw I the cold air to cool it down to about 10 degrees below my target temp. I did not even have to insulate it because the lights do such a great job as heaters! Right now temps are down to the teens and my temps are holding in the 70's. This is easier than when my cabinet was in the house because it was always a battle with the heat. I am growing lowryder 2 autoflowering so I just keep the lights on 24/0. When it starts to warm up it will be changed to 18/6 with lights out during the afternoon.

Just wanted to share my setup with anyone considering a winter attic grow.

Cabinet is producing the best Lowryder results I have ever had and with this setup my fan is overkill. I could probably get by with one of those whimpy 4 inch inline fans. I Lied about the attic thermostat at Home Depot. It is $23. Keep in mind that you can only do this in winter and only with an autoflowering strain because the lights have to stay on 24/0 unless you want to throw in a little ceramic heater. With a heater you can cycle the lights I guess.

Update: i have a monster lowryder still growing. Temps are warming up during the day so I have a timer with lights off during the afternoon. I figure that it will be a good grow enviornment for another month. I can grow in the attic with this setup from late October throught late April. Six months ain't bad and my yields are the best yet. Still curing, but looks like well over an ounce per plant dried.
