I'm hoping to raise all my plants from seed this year. I've already sown a
couple of trays in heated propogators on the windowsill and I've got a
greenhouse on order. Got a couple of questions though

1. When the greenhouse arrives how warm will I need to keep it so that I can
safely put my seedlings in it once I've potted them up.

2. The greenhouse is only 6 x 6, any ideas how much wattage I will need to
keep this at the suggested temp

3. What the cheapest method of heating, presumably electric, but what sort
of heater fan, tube etc

Thanks

Jim
