First off, welcome to FragOutpost.com Coastal!
I have been wanting to set up a greenhouse for a while but my backyard does not receive enough sunlight as it is shaded by some large trees. I plan on building a greenhouse when I move in a couple of years.
Are you having trouble controlling temps at this time of year? Are you running a geothermal loop? What size are your vats?
Nice photo. Those are some nice frags.
I'd like to see some more photos of your set up if you have them.
