installed fan last night and temps are way down. This morning i got a reading of 69 after a fairly cool night outside. This afternoon temp was a nice 74 with a nice 77 outside. This will be but to the test when summer temps arise.

I am concerned about over/underwatering. I am fighting the urge to water every time I check on them, which my wife says is way too often.
The top layer of soil gets dry fairly quickly but I can see the discoloration in the bottom of the peat pots and know there is moisture there. I am also handling pots in order to get a good feel for the weight which has been noticeable the one time I think they were overly dry.

I moved the lights back up to about 4" away from tallest seedlings. Half of them are 2 days older and about three times taller. Will post new pix tonight.
