So last year after killing off the first set of seeds, I made a seed starting box, with lights, air flow, and heat (from the lights). The plants thrived.
Here is how its made...
Step 1: Materials
3 temporary bulb holders (home depot rubber coated) UPC # 0 78477 83939 1
3 CFL 13w light bulbs (do not use other types the heat would create a dangerous situation)
2 wire nuts
1 cord end (I got this one off a dead microwave) a short extension cord work well also
3 band ties
double sided tape
piece of bubble wrap the size of the bottom of the container
hole saw (the size of the bulb holders) 1 1/2"
