That's fucking awesome! Pricing out/ learning to build solar panels is on my list bro, I'd love to see pictures. I want to use/build wind turbines too. Have you looked into geothermal cooling? Growing in the basement is basically doing it already but if you dig down a few feet and snake an air duct through the ground, then bury it, all you need is a powerful fan going in and one coming out. Once you get a few feet down the ground stays cool all year long, no need for AC. I want to build a 100% sustainable model for indoor growing and that's how I'm planning on managing temps:smoking:
Yeah man LED's are the only way to go if you want to save power, and you'll be able to cut way back on the HVAC bills too. For your seedlings & clone area The Cannon would be overkill, I'd recommend some mid-power samsung strips or even Cree XP-G3's. They're extra efficient and you don't need lots of power so you can cut back on watts there too...
