Does Harvard or any of the other schools have any greenhouses open to the public? Thanks!

Would the county agricultural agent (USDA) likely have this information ? Could this information be found out through some sort of building permit report. Who would know what was being grown in these greenhouses ? and if any, many use hydroponic systems ? Have any schools, universities become known for this practice ? If glass is no longer used, what is the material of the usual covering, or panels ? Are any of these greenhouses that might exist, producing in a commercial circumstance ?

The ones you can buy at any garden center and the leafs are plump and it says sorensen greenhouses on it, and on the rapper they show a mexican man sitting on sand with cactuses.

Are there any retail greenhouses (for tropical plants) in the greater ST. Pete Fla area that I can go to while on vacatiion?

Why would people put large containers of water in root cellars or greenhouses during the winter?

How do you make paper greenhouses or cloches? How does the plants grow? Can you use newspaper to make a cloche and put it over the plant?

I am curious as to the viability of greenhouses in colder climates producing food year round that are heated entirely by geothermal. My understanding is that geothermal can provide heat to about 54 degrees f. So, a follow-up question would be, are there food crops that will produce at those temperatures?

not like boquets of flowers but single plants and flowers like you would find at the shopko floral shop or walmart. some greenhouses must have to order them....but where?

I am researching greenhouse gases on the internet, and all it's taught me is that they are a gas. So do greenhouse gases really come from greenhouses?

I'm doing a science fair project, determining which greenhouse gas absorbs the most heat, and I need to get water vapor, methane, carbon dioxide, and nitrous oxide. I was wondering if i could buy like bottles of these types of gases, without harming myself or my family. I need to release the gases into 4 different mini-greenhouses, and i'm not sure if its possible. HELP?!! This think counts for 6 test grades!!
