1st of all thanks to all.
the peg board is actually drilled to the wood, due to no holes in the sterilites i decided to go with peg board instead of particle for ventilation purposes. i kinda get the temps i want. my females that are cooling are ok with no heat at all due to the texas heat. but twhen the heat is on i can get 80-92 easily. i have lutron dimmers controlling the pads.
thanks again! felipe
