ive observed all the variables I can think of and here they are. 10x12 room, window unit, 3x600, 1x400 hid lights. Ambient room temp 72-73 thermostat controlled. Smart pot root temperature 65-67. This was consistent whether on the floor or elevated on a 10" web pot x 4 mature plants in soil. Compare a same size regular plastic pot right next to them. Plastic pot root zone temperature 71-73 consistent whether on the floor or elevated x 4 mature plants. The plastic was close to ambient. All temps were taken 3 days and nights in a row with a industrial thermocouple measuring 3,5,10 gal pots with growing plants. It seems counterproductive to have soil that cold. Everywhere I've now read 72 is the sweet spot. 5-7 degrees! I used a heating pad to warm it up and it did but it cooled off again. The plastic pots were spot on. maybe this correlates to a lot of my plants taking weeks too long to finish? IDK I just snapped to why some were doing better than others never looking at the pots right in my mug.
