Thanks for the tips and the heads up on SUBSCRIBE HGA-L .... I just

One hint for small greenhouses in winter, if you can: Water with room temp
water rather than freshly pumped. A simple way is to fill a bucket or
carboy
near the GH roof, and then let that warm in thehouse, and water with the
warmed water by gravity.


I am curious about this one. Is it a happy plant issure or are you
saying one can save energy this way?

The latter seems unlikely.

If you don't want to chill the ground with water from the tap (you know
the pipes are in the ground and the water will be the same temperature)
place a 5 gallon carboy (demijohn, whatever) high in the green house
where the warmest air will collect and warm the water you are going to
use on your plants. This will keep the ground temperatures up. Capice?
