Buying or building a greenhouse?

Sorry but I think this veering into the dangers of aluminum is really a bunch of stuff and nonsense!

Who is soaking their greenhouses in acid??? And is who is using their greenhouse as a vessel to cook food? What does this have to do with using aluminum channels to form a greenhouse. They are physically a very small percentage of the structure and I don't know anyone who uses acids to clean them.

My brain is hearing the loud blare of BS detectors going off in regards to how aluminum is not safe in a greenhouse!!!

 

Why worry about the small stuff when Fukushima's going to poison the planet anyway ? Sad but true
