New to this site and must say it's great.I am in the process of buying
a greenhouse and wondering whats the difference between horticulture
glass and toughened glass

Are any of you using the various double/triple wall polycarbonate glazing
options? Mind you, I'm in the northeastern American colonies, and winters
are a bit colder, assuming I want to at least grow hardy greens year round.
I'm currently using a cheapo tubing frame/plastic cover house, perhaps 8 by
6 feet, and the R-factor is, if anything, negative! There's a bok choi
hanging on somehow, but not growing at this point.
