  • 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.

    That's cool...My seed starting rig is simply a wood box with a thin pressboard top...A 25 watt light bulb suspended on each side...Will hold two flats of seeds on top easily...Heats the seeds from the bottom...Holds a constant temp of 70 degrees...But It wont proof bread... It only warms up seeds...

            I got it on eBay.

            I made this because I saw this chart that each different seed has a different ideal germinating temperature;

            Also, 99.5F is considered to be ideal for egg incubation, 110°F to 115°F for yogurt, and 80F and 90F degrees for dough proofing.
