Apologies if i am posting this in the wrong place. My grow house is quite small and gets a lot of direct sun for almost the whole day and i don't want the pots to overheat. [Un]fortunately, they are all black plastic. Is there a way i can keep the pots and the substrate cool over the summer? Would putting the pot inside and empty pot of the same type (so the outer one heats up and the inner one is a bit cooler) be any help?
Any thoughts or advise would be much appreciated.
