EASY & CHEAP HOMEMADE HEATBOX SEED GERMINATOR
- Plastic cooler
- 50 count strand Christmas Indoor/Outdoor Christmas Lights or Rope Lights
- 15×10 pan (I used a jelly roll)
- Extension cord
- Put the Christmas lights in the bottom of the cooler. Make sure the electrical connection is outside the cooler. I do this because there is A LOT of condensation that forms in the cooler and I didn’t want water on the connection of the extension cord and the light strand connection. My thinking is the lights themselves can take the condensation since they are indoor/outdoor lights and they are used outside in my SNOW & RAIN weather. I used only 50 light strand and that produced enough heat to stimulate germination. 100 strand lights or larger would be TOO HOT.
- Put the pan on top of the lights. This will prevent water sitting on the lights that has maybe drained from your seedling containers.
- Put your cell packs or any other seedling containers on the 15×10 pan.
- Close the cover of your cooler.
Most of my seedlings sprouted in a few days. Of course, some seedlings take longer… like peppers. I left the lights on DAY & NIGHT. I did check them daily to see if the condensation was affecting the lights in any way. Everything was fine. Not only is this a CHEAP & EASY method of germination, my success in starting from seed was the best I have ever done. I found this method of HEAT GERMINATION better than the heat mat because the seeds seemed to stay at a more even moisture. I know this box doesn’t hold A LOT of seeds , but I don’t need a large amount all at once. After I see that the seeds have germinated, I take them out and put them under grow lights. Then you can put another set of seeds in the HEAT BOX SEED GERMINATOR.
