Home made electric propagator problem...
In Feb this year I made a 1200mm x 500mm electric propagator with a Parasene thermostat and warming cable. The problem is the sand above and below. I used 50mm of horticultural sand below and 50mm above the cable and kept it moist but it went solid like concrete. I thought horticultural sand had no lime in it? Any way, I have just broken it up and thrown it away. Does anyone have any suggetions either for what I am doing wrong or what other medium I could use to keep the cable from overheating?
