Hi guys!
I’m building this greenhouse with my grandpa and the plans for the one I chose has corrugated polycarbonate but after reading I’ve found that maybe twin wall would be better for where we are?
I’m in zone 5.
The greenhouse has full sun (south facing)
But snowy/cold winters none the less.
I plan on running electric heaters out there since that’s what I did with my first greenhouse (twin wall but only 4mm) and it worked great.
Just here asking does twin wall really make a huge difference on keeping heat in vs corrugated? If I’m running a heater?
Thank you!
