Greenhouse heating question

[jeff]

Depending on your needs, I think you will be hard pressed to heat only with solar or steaming compost.

Solar requires thermal mass and added insulation.

I've got a string of nights here in the 20's, so I'll see. I've been adding both thermal mass and insulation. I do have a heat lamp on a timer... It's my first winter with the "solar cabana", so much remains to be done.

With that said day time temps have been a delight inside with outside temps in the the 30's.

No objection to any form of heating, but insulation is often overlooked.

I've done similar with 3-4 gallon container plants with homemade heating jackets, simple 1/4" plywood boxes that house the container and a heat source. A single 7.5 watt light bulb on a dimmer is all that I need to keep a pot at an optimal 75 - 80 degrees F even if room temperature drops into the 50s. Plants given such a cozy set of overshoes thrive, even at 60F air temperature.

Thank you Ingrid!

Even though it was an old posting. I knew the answer to my own question. What I found was, some posters felt the oxygen factor was insignificant in the propane heating question.
