Inspired by the germination chambers AJ and others have built, I decided to trick out my shelf. A trip to home depot provided all the supplies I needed for about $70. I decided to go with foam walls and floor, and add two 100 watt incandescent lights on a dimmer for heat and temperature control.
The first step was to cut and install a plywood doubler on the bottom side of the shelf so I could install the lights.
Here is the shelf back in its place:
Next step was to cut and place the foam back and walls.
I wired up the lights and installed the front.
Finally, the seeds go in and the door goes on. I don't have a picture of the door in place - but it just looks like a big white box.
It took a little tweaking with the dimmer, but the thing appears to be rocking steady at 86 degrees F. The 100 watters may be a bit much. I had to crank them way down to keep the temperature down. Sixtys or Fortys might be better. I won't use the chamber for growouts - just for germination. Pretty simple project, but it hopefully provides the micro-climate I need to get those hooks popping.
