Well, heres an interesting observation.
I got up this morning at 6:45. Temp in the "Seedling House" was a balmy 27 degrees, with 90% RH. This is according to a wireless Accu Rite Thermometer. I placed the transmitter on the bench where the seedlings were.
At 7:50 the temp creeped up to 31 degrees, and still holding at 90% RH.
On a whim, and I wish I had thought about it sooner, I went out and moved the transmitter to the ground.
I came back in the House and noticed on the receiver that it indicated the temp was now 32 degrees.
That could just be from touching the unit.
But then just a few minutes later, it went up a couple more degrees. And the RH went down 1%
Now, it has been 23 minutes, and the temp is 40 degrees, with an RH of 88%
A couple points to keep in mind. The sun is shining, but there is a heavy frost on the plastic, blocking the sun.
I just looked and now its 41 degrees.
I think this is going to need some repeated tests.
