Heating Mats.
I've bought two seedling heating mats but I'm not sure how to use them. I've planted the seeds, put the seedling trays on the mats and plugged them in. Do I now leave them switched on 24/7 or do I turn them off during the day. I know this might seem like a stupid question to all you hardy gardeners out there but I'm still a novice. Thanks for any replies.
