Heating Green House

[Armchair Expert]

Does anyone here heat their greenhouse?

If so what heater do you use, how much does it cost. Looked at paraffin heaters today, guess they do not have any form of thermostat?

I ewas thinking of trying to grow tomatoes over winter, but the cost seems to be to high

Do tomatoes ripen with heat and no sun?


Anything else?

Tomatoes ripen by producing ethylene gas. Once the tomato starts going red you can remove it off the plant and store by putting it into a box and adding an apple or banana to it quicken the process, so does wrapping it in paper.

Although I believe that below certain and above certain temperatures the tomato will stop producing the gas I think it is something like above 85f
