All I did was to drag into the garage, an old set of shelves that my wife sometimes uses as a plant stand or to hold potting supplies in the warm weather. I set up two grow light fixtures of two bulbs each, and placed a clamp on fixture and a light that I used under cars changing oil underneath, add one power strip, cover with leftover plastic sheeting, and instant seed starting tent with heat. The square item on the seed shelf is the temp sensor for the indoor display. This was about 10min of time to construct. The temps stay in the 70's - 80's, depending on the temp in the unheated garage.
The temps are warmer than the house, so it works out better than starting in the house without a sunny window.
You can't see any life in the pictures, but about 25%-30% are up, with more every day.
Nifty. Thanks for the pics. Sounds like a great set up.
