This is an upright freezer that died yrs ago and never got trashed. Thanks pup for ur thread to copy and great help. Also thanks to bwanabud for his 3/4 inch pvc frame, 1/4 inch pvc coated galv. screen idea and help also. I got an analog timer that will repeat dn to 15 seconds, on and off. Also an 8 channel indoor/ outdoor thermo-hygrometer with 3 remotes. it might be overkill but will keep close track of temp/ rh at top 25%, bottom 25% and air as its entering intake of cabinet. As well as an led motion light. Am excited to see how well this will work.. THANKS!
