Hi! from Montana

Searching for information on starting a GH in zone 3B......starting dates,heating,cooling etc.

Stevensville, MT(Zone 4b)

Plan on using G/H for doing my vegetable starts, hot house tomatoes, peppers..
My temporary greenhouse is 6x10 plastic. Have purchased a self contained gas heater for cold nights in March. Plan too have fan blowing too circulate the warm air.

bought a gas heater for my temporary green house 6x10(plastic). Just read that it may cause ethylene poisoning to your plants without adequate ventilation. If I need to turn on the heater then I can't very well open the window.....now what to do????
