Hi I am waiting for my greenhouse to arrive, it is only 6ft3ins x
6ft3ins x 6ft7ins and i was hoping someone could tell me which kind of
heater i would need.......g.s

Where do you live? It is based on night differential temperatures
because rarely does a greenhouse need heat during the day.

I have a 10x20x9 center ridge greenhouse. I use one space heater and
make sure the greenhouse is sealed off from wind and drafts. You may
be able to get away with one of those oil filled heaters in the center
of the greenhouse, but again I have no idea how cold it gets where you
live.
