## Description

BAYLISS GREENHOUSE AUTOVENT XL

Review: Works good so far - I built a custom greenhouse with a wood frame, and needed a way to automatically open a window for ventilation. I bought the $20 one from Harbor Freight, but it didn't appear to ever work, so I returned it. Decided to pay up for this one. So far, it works perfectly and reliably for about a week now. Installation was easy. I made an adjustment this morning so the closure is now flush. I love having a greenhouse that doesn't need constant monitoring. It's a bit expensive, but all the good ones are. So, until Wal-Mart starts selling these, I will have to live with the price. But, it was worth it to me, to have automatic ventilation. I also like that the hardware never extends more than an inch or two into the greenhouse, which will allow me to build a screen frame that will keep rodents out.
Review: Perfect for my DIY cold frame! - I build a cold frame using some 2x's and an old window, but needed something to handle venting it as I work full time. This thing has been fantastic, allowing me to easily and without any effort acclimatize my plants as I transition them outside. Once I get the real tender plants out I'll be removing the window and the venter to grow lettuce until things get chilly enough again to need it. Highly recommend, great quality!
