I built our “plant room” about 2 years ago – just a small well insulated room with a lot of windows and shop lights – and since then I’ve tried starting my own seeds with varying degrees of success. The problem that I’ve had is that over night temperatures in the room routinely fall into the 50s which is fine for maintaining tender plants over the Winter, but makes seed germination spotty at best. I knew that what I needed was bottom heat.
The thing is that retail bottom heat is expensive – I saw one “kit” at a local garden center that was big enough for 2 flats and was $79 – wow! You can buy a lot of tomato plants for eighty bucks! A low cost alternative had to be possible for a dedicated scrounger like myself.
Whatever I decided upon had to be:
- Safe – neither an electrical shock nor a fire hazard!
- Big enough to start all of our early Spring seeds.
