Here is the cold frame I built and I am currently using for seeds started January 14th.
The lights come on when temps drop to 37 degrees and go off when inside temps get to 45 degrees. The temp has been in high teens to low 20s the past few nights and it seems to be working great. The large pipe is a cold sink to let out the colder air when the lights come on to heat the box. Daytime temps are around mid 50s and I occasionally raise the door a few inches after the temp gets above 32 outside just for ventilation and let the breezes make the plants more stocky and sturdy.
The other picture is of my new beds which are a work in progress but will be completed with drip irrigation. cages,t-post, and mulch. Yes I did put down the tarp however there is no tarp underneath the beds, and should have no weeds between beds. I did space them the width of my mower just in case the tarp idea doesnt work out. I just wanted to post the progress but still lots to do.
