I was thinking about my green house. What can I use for a green house. Then I thought about bubble wrap. Has anyone ever used bubble wrap for green houses? So I did a web search. And people do use it. Mostly for insulation in glass houses. People also build green houses with plastic bottles. So maybe we could also think about doing that? But plastic bottles have a high deposit in Germany, so cost is a factor. Here are some photos. Maybe I can use straw bale for the bottom of the green house and plastic bottles for the top of the green house. Just an idea.
