Hobby coral farming with Hobby Greenhouse

I am considering buying something similar to this to grow coral....

Keep in mind, this isn't a commercial operation, more of just for hobby/ viability study.

My question is, is it just outlandish to think this greenhouse will be insulated enough not to cost a fortune heating? I'm only heating an 8x8 space and can cover it with an additional layer of polycarbonate, but then again it is only polycarbonate. I live in delaware and the winters don't get too bad. I think summers won't be a problem with the addition of a fans/evaporative coolers.

Has anyone tried such a thing before? Is there a better solution for a very small greenhouse "on the cheap"?

Quick general rule: build your greenhouse anticipating the hottest and coldest days of the year. Anticipate also possible electrical and/or natural gas failure. It only takes one crummy day to kill everything.

That size is not worth the trouble. Far easier to keep a few frag tanks in your basement/garage. Way too much work for temperature and light control.

I agree with both comments above - We had a -19 degree night and really appreciated the extra 25,000 btu larger heater unit we purchased.

I think bigger the better with a greenhouse. If your going to lose sleep with it, and you will believe me, its better to make some good money when/if it succeeds.
