Roof Vents vs Exhaust Fan

Good idea, @CanadianLori,l but I just put weed blocker.

This is kind of back to the beginning of this thread where you were talking about your solar powered roof vent openers. There is no need to "seal off" this part of the greenhouse. You can remove the wax cylinders for the winter. I would also come up with some kind of plan to secure the roof vents so that they don't blow open with the wind. To remove the cylinders you usually just unscrew them using the thumbscrew, but check on the specific brand that you have.

All of the greenhouse vents come with manual openers which I place directly beside the automatic heat activated openers. The cylinders are not pv powered. You can simply disconnect the bottom arm and leave it hanging unless you are in a harsh environment.

I have three greenhouses. All hobby size which build up heat pretty quick under a clear sky and nothing has been more effective than using louvers in combination with vents. The air flow on a hot day will impress you.

I have to say. Reading posts from our cousins across the pond, I find so interesting.

Hello all, new to this forum. Have to say I really enjoyed reading this thread. Moon your GH is awesome! Looks like you are well on your way to a successfull thumb of green. Nice pics and very informative posts. Thanks. I'm a GH beginner and will need lots of advice. Assembled a Palram unit (6 by 10) the deck is firmed to posts at the corners concreted in the ground. Steel cable over the peak in two places to anchor it to the deck. It gets quite windy here in Nazareth. So far so good. The polycarbonate panels flop in the wind so I plan to clear silicone caulk each panel in its track. Already have light and outlet in there. The roof vent is a joke. Will have to figure on how to cool it down over the summer. I'll have plenty of questions as time goes by. Seedlings are coming up in the house. Looking forward to transplant time.
