paraffin heater

[marc555]

Wanting to start my tomatoes off in my greenhouse, problem is its been frosty last few nights but warm during the day, been down this morning and the temp in my greenhouse was 32 C.
Im back to work on Monday so if i leave my paraffin heater running during the day will it get too hot. I cant get down first thing in the morning to blow it out

Any advice?

Fit a thermally controlled vent.... it'll let the heat out, though it's expensive to keep burning the paraffin

There's been a bit of discussion on here lately about puting a cheapo plastic greenhouse or even a covered propagator inside a greenhouse to keep the frost off seeds and young plants.

Paraffin isn't cheap and to heat a greenhouse might end up costing you a lot more than you think, even if you only put enough parafin in to burn for a few hours every night.

Might be best just to start seeds off at home and move out to the GH in April.

(well, you did ask  :))
