How about putting ice cubes on the perlite to cool the temperature? What about adding the occasional hot steamy water glass to sgfc to increase humidity? Lastly, I wasn’t having luck with my sgfc so I put the perlite in a monotub. Put the cakes on perlite with foil of course. Are these good or bad ideas?
