I made a DIY Heat mat last weekend. I used some small christmas lights placed inside of a plastic rubermaid type tub with cat sand poured over the lights. I have them on a timer that is on for 15 min and off for 15 min. I then placed my jiffy pot plastic tray with the transparent lid on top of the cat sand. I put a thermometer inside and it is maintaining 85 degrees. So far my germinated seeds from coffee filters in plastic bags are placed into 1.5 oz plastic catfood cups with MG seed starting mix have been loving it.
This whole DIY seed starting kit cost less than $20 including the tub, lights,cat sand and jiffy pot seed starting kit.
