The little greenhouse I set up back in January now has 3 sets of Christmas lights in it, and its maintaining about 10 degrees above air temp, despite having little to no sun to warm it.
The lack of sun on the greenhouse worries me a bit. Shoulda remembered that this is upstate NY and we get, like, no sun here. *sigh* I’m now researching grow lights to go inside them.
One tray’s worth of seeds have sprouted and are going strong.
The other tray sprouted one seed.
I’m not sure what the difference is, BUT, the “good” tray IS 2ft higher than the other, and apon wielding a thermometer I discovered that the water in the bottom of the higher tray is 5degrees warmer than the bottom tray. So, I re-did the insulation under that heat mat (the bottom one was looking sketchy), and swapped the trays, to see if that makes a difference. Oh, and replanted those pots…..I also picked up two more heat mats, we’ll see, but this way I have backups, just in case.
