Has anyone ever built a greenhouse made out of 55 gallon polyethalenne
I was thinking of building a greenhouse with the north (and east & west
possibly) side built of 55 gallon plastic barrels. The barrels are
black and could serve as a great heat store. The problem is how to
secure them so that if I stack them (2 high = 6 feet) they are
structurally solid. I'd like them to serve as the outside wall (no
other siding necessary). But the space where the barrels meet on there
edge will need some sort of insulation that would be exposed to the
outside. Maybe I do need some kind of insulation on the outside so
that the barrels will not get cold.
I was thinking of making the greenhouse 20' wide (20' exposed to the
sun). So the north and south would be 20' (one side of barrels, one
side of glass.)
Any ideas on using barrels would be greatly appreciated.
Has anyone tried this? What problems did you encounter?

Fill the barrels with water and they act like a heat sink and at night will
slowly cool off, keeping the greenhouse warmer at night. This doesn't work
during cold spells like we had last week, but in mild winters, my barrel wall at
the north side of the greenhouse indeed was enough to keep it warm. Now, I do
have a structure with a sheath. It's an inexpensive greenhouse I bought for
about 700 dollars. It's 10x20 feet and 9' in the center.
You would have to stagger them for stability and then use appliance ties to hold
them together. You know that stuff that comes on huge boxes...it's the plastic
tie stuff. You can buy it with a special gun that tightens it. OR, you could
go to Home Depot and buy straps and buckles to hold them together. They last
forever if they are made of nylon, which most are.
Many things you can do.
