I'm going to be doing some growing over the winter in my garage and at this point I have this light picked out. http://www.amazon.com/iPower-GLSETX600DHMWING20-600-Watt-Digital-Dimmable/dp/B005DOS0R8 Will I be able to get away without any cooling for the light? I live in Florida, so it does not get too terribly cold. If there are any better options (price-wise) out there for lights feel free to recommend one.
