Plug tray and heat mat

11 years ago

Can a plug tray be placed directly on a heat mat or does it need to be in a 1020 type tray that keeps it right above the heat mat? My plug trays don't fit properly on the 1020 tray holder and so they warp slightly in the middle, but I'm afraid maybe the heat would be too much if the plug tray is set directly on top of it since seeds don't seem to cooperate and all germinate at the same time! :)
