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.

Our little self built greenhouse has a twin walled polycarbonate roof.
Doesn't seem to bother the plants, some do grow a bit leggy but that's
more
likely because it's on the N. side of our garage, overshadowed by a good
sized Camellia tree, and very crowded in there.

Our greenhouse has double wall polycarbonate sheets from Screwfix. It
isn't cheap but is very effective and unbreakable.

Wow, we have a Screwfix on a trading estate in our town. *I'll go and have a
look, although it depends if it fits our elderly greenhouse. *Thanks for the
tip.

We order from Screwfix and have it delivered to our daughter. Is
Screwfix B & Q?
