I use two layers of poly on my green house - the inner is Tufflite IV IR
and the outer is Tufflite IV Plus (8 mil UV coated).

I inflate with air between the 2. I tried just the IR in 2 layers when I
first got started and had to replace the outer layer in 2 years...it
just died.

I go 3 to 4 years between replacements depending on the damage that
falling Ice does off the barn and other damage to the inner and outer
layers.

I get by on about 1/2 the fuel I used with one layer the first year -
and I now run a higher night temperature then I did then.

I too am in Michigan.

Isn't that what Al just did? Add on to his GH with an inflatable poly?

Does anybody have a recommendation for polyethylene film for covering a
greenhouse? So far I've been tempted by Tufflite IV infrared, which is
supposed to last 4 years and bounce IR back into the greenhouse so that
the plants stay warmer in the winter. I'm pretty sure it is cheaper to
buy expensive plastic because of the fuel savings. Michigan becomes
more tropical every year, but it still has a ways to go.

It all seems expensive (and heavy to ship), but there is at least one
local dealer for this stuff (in Westland, MI). I can't seem to find any
others.

Thanks for any tips or recommendations

Rob
