What do other orchid growers do ?Do you shut up the greenhouse and use fans internally 24/7.This is what i do ,but i am thinking of installing (adding to this) two 100cm round core vents at low level at each end of the greenhouse grilled on each side so they will be permanently open to introduce fresh are.Now i am thinking will this be beneficial and will it effect heating costs/heat loss . Thanks Keith
