ROBERT JOHNSON Posted October 11, 2017 Report Share Posted October 11, 2017 Small pause whilst you insert your own jokes!! Now my question. I've just built my first greenhouse an Elite High Eave with toughened glass and bar capping. Having had a few windy days I would like to know what wind speeds are considered too high to leave vents open. I am concerned that if I close all the vents because of wind that I am putting my plants, mostly Sarracenia, at risk of mold growth. Are winds gusting to 30 40 mph ok? Or what speeds would you suggest? All advice for a new greenhouse owner would be gratefully received. Quote Link to comment Share on other sites More sharing options...
Steve Werzal Miller Posted October 12, 2017 Report Share Posted October 12, 2017 That’s something I’ve been trying to figure out too. I’ve been closing the vents and door if winds are about 30. Mine hasn’t got toughened glass though. I have installed a fan to help with air movement if the door is closed but I leave it running 24/7. I’d be interested to see what others say though.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
ROBERT JOHNSON Posted October 12, 2017 Author Report Share Posted October 12, 2017 I have also been using 30mph as a cut off point. I have been looking at an app on my phone which gives me forecasted windspeeds hour by hour. If the app shows gusts of more than 30mph for more than an hour at a time I batten down the hatches. But am I being over cautious!! Quote Link to comment Share on other sites More sharing options...
Alexis Posted October 13, 2017 Report Share Posted October 13, 2017 You should be fine I would have thought in any weather that isn’t very windy. I’d just close them when the Met Office gives out a yellow warning for wind Quote Link to comment Share on other sites More sharing options...
ROBERT JOHNSON Posted October 13, 2017 Author Report Share Posted October 13, 2017 Hi Alexis Thanks for the advice. There appears to loads of information on what to do when it's windy. But nothing to guide you as to what is considered windy! Quote Link to comment Share on other sites More sharing options...
