The ventilation in my greenhouse is really bad even with a louvres in the back panel(not in this old picture). The original window blew away in a storm which has been replaced with a sheet of polycarbonate.
Does anyone have any suggestions for a diy window to fit in the sides or top.

Can’t you just leave the door(s) open when it gets hot? Or swap them out for a screen door during the growing season? Or cut out part of a panel to make a window, and mount the cut-out piece to a wood frame so you can bolt it back on the GH in the winter?
Just get more twin wall polycarbonate sheets and cut them to size. Should be pretty easy to do with a box knife.
You also need more ventilation than just exhaust louvers. I suggest cutting out intake holes at a low point in the front and installing these [non-powered louvers](https://www.amazon.com/iPower-12-Inch-Aluminum-Automatic-Gravity/dp/B08JGBT63V?crid=2TCSHS1DK820L&dib=eyJ2IjoiMSJ9.TopYBxID97aruTg-X84ic1uuxLLx6N5bzGC5xIyin2ccZOpblX2-pVxrKq-G4MH-VIFgaNfRTDVqlmKkM6fOY9724QygcsG_qYUfkqqxf7GLrupDzjL5n3Ibjy6ui6o_wOXwnWPgYj2IMztXbjBYXsKhkjVvq_WoB2E0GJeXMWIkQBPdLMXWKxqZlQX4ho5Kcs5ytsfX_5GkNR7YUIQkl09J-FV0GDZiGdTjpd9H2TzQp8NyLlxQnuvNslBpxhXLlwJ3QiO15V6QOtIS1hcsAr-0Ty4ByF_LhFPLHtxRBEL1JCaVzloNKOn19yxNWdP724vpdidmFl7qFKgPqldv7x2X5BUUSMvw2rM8QFYhbbTdfwC2hRPfYcOo4IThTXXddm8_-_BGMhF8byK1kAN8kmGxbwShMtOrQFXv5QQKpTkqay4yHnzocrAqXrIu1roa.1EPA_SNZVbuhCstAVeZVSH8is-C7FEImpDXK5GfZjwo&dib_tag=se&keywords=greenhouse%2Bintake%2Bvents&qid=1741028961&sprefix=greenhouse%2Bintake%2Bvents%2Caps%2C171&sr=8-1&th=1).
