Okay Frame is Plexiglas. We have an abundancy in our shop at school and can freebuild all the time so it wouldn't be hard for me. Caulk and glue airtight. I think its a good idea.
Just thought about it in school today. May be no good but at least i tried.
how would it be stealth if you need all that electricity? gonna put it on your property or something? seems like a lot of work for a low yield unless you put serious money/man-power into it...
I thought of this idea for kids who are trying to grow without any parents knowing, or Guardians. thus, the underground grow. Just an Idea, trying to share with community.
