As we all know, HID lights kick out alot of heat and its a PITA to deal with high temps. and overheating. In the wintertime, that all changes. HID heat becomes your friend and is easy to manage. Not enough heat becomes the issue. My goal this winter is to heat my crib entirely from grolight heat. Here are the issues I have daydreamed about so far.

1. It will be necessary to have a dual gro setup on a flip flop schedule. What sucks about this is that both gro rooms need to be separate and lightproof from each other, yet still able to exchange air with each other freely. Each room will be about a 1000watts of light which I'm counting on to heat my whole crib which is about 600 square feet.

2. Rather than exhausting outside, the blower will redirect the heated grolight air to the other room of my crib. The air will work its way through back to the groroom1. Groroom1 is adjacent to groroom2 and the air should pass through from 1 to 2 in series without restriction. Some kind of a lightproof air baffle seems necessary. I have heard about darkroom louvres but would rather do something simpler if possible. A few pieces of plywood arranged in two 90 degree angles painted black should work but its still quite PITA.

3. The blower will have a carbon filter on it. The hope is the constant recirculating indoor smelly air can be cleansed without having to exhaust to the outside as much as is usually done in the summer. My fear is that smell wont be eliminated as easily this way.

4. Preferably, I'd wanna minimize exhausting to the outdoors so as to conserve the heat. I will need some ventilation of course to replenish co2 and lower humidity but I want to put a smaller blower, say 75-100cfm running 24/7 to the cold outdoors.

I have searched around some on this topic but its hard to get definitive, uncomplicated advice. I'm willing to experiment but I wanna ask yall fellow farmers about it first. Peace
