Default Re: DIY greenhouse - $30 maybe

I opened the door in the morning
Also vented one roof panel about 8" & I took down 1 storm window
It still went up to 85

So I put the solar heater for the hot tub on top of the greenhouse back against the house
I had to go buy some hose & clamps to connect it to the hot tub
By the time I got back from HD & hooked it up it was maybe 2:30
The 1st water coming out of it was steaming hot

By that time 1/3 of the panel was shaded & it was after 3pm
It was still raising the Temp of the water 6 degrees
But I shut it down until tomorrow

I want to see how much the 4' wide solar water heater panel shades the greenhouse
