What The Press Say
Amateur GardeningMay 2013
Tried & Tested Greenhouse Vents
Best Buy - scored 19 out of 20. "A very well designed and constructed vent opener, which had the best micro-adjustment temperature controller. You could leave it alone in confidence that it would do its job well over a long period of time. Bayliss say that the vent will work on a vertical side window. Worth the money because of its quality and versatility."

"Don't let your plants suffer in the coming summer heat. This automatic vent opener for the greenhouse allows air to circulate and, as the temperature changes during the day, it automatically opens and closes. This model is suitable for both aluminium and wooden framed greenhouses."
