yep...horticultural heat mat set around 82-84. Tray, Humidome, medium of your choice, floro, spray bottle, clonex or olivias or something you like, thats about all you need for cloning....ya know-clean scalpels and other bits too but you get the jist of it. those humidomes always keep it reading 99%RH on my humidistat/thermometer that is on the tray with my clones. But the read out only has 2 digits for RH. I believe it probably 100%.
