Punxsutawney Phil
Punxsutawney Phil, the official groundhog, has predicted that there will be many more weeks of freezing weather. Which means frozen ground and problem starting seeds for the garden.
I put together this quick and inexpensive precision seed starting chamber.
A digital temperature controller. ($15.00)
A 12V muffin fan to circulate air ($2.00)
An old light bulb for heat ($0.00)
Some old 1" foam board to make an insulated box. ($5.00?)
Time for construction - about two hours.
Essentially a big SV cooker using a PID controller to circulate hot air instead of hot water to keep temperature within one degree of accuracy.
I can't think of another reliable way to start seeds quickly.
This box can be used for bread proofing, yogurt making, egg incubating, hot food keeping for transportation for long distance------
The box is very strong, and can be taken apart for storage in one minute, and put together again in 5 minutes.
