Soil Temperature Question

is there any way to lower the soil/root temp of a soil grow on a hot day?

Paint your pots white, or do something simliar to reflect that heat (and light). edit: was just my first thought, I have never tried that as I don't have that problem.

what are they on/in? put your pots on a raised bed, especially if theyre on concrete or anything that holds alot of heat. otherwise-just make sure your grow room's temp is down and you shouldnt have any problems with soil overheating....what makes you think thats your problem? whats the temperature?

Warm soil is good, promotes healthy root growth. Just keep your grow area temp right, and you will be good.
