Some great venting ideas in this greenhouse! posted on november 10, 2010 | categories: greenhouses for sale this custom greenhouse incorporated a large continuous side vent with a refurbished chain driven pulley system and cast aluminum wheel.. The vents are hinged and attached to a rope with a knot in the rope to stop the vent from opening all the way and breaking the hinge, just in case the rope slips out of your hand
