The secrets of the greenhouse
January 18th, 2008 | by admin |Granduncle is an enthusiast about growing tropical plants. He took us over to see the greenhouse set up on his club premises. Explaining the secrets of the Greenhouse he suggested that we open a small window near the roof. Immediately the inside air rushed outside and the inside temperature dropped. We were no longer in the tropics! The system is based on the auto vent-automatic cooling method. Electromagnetic radiation is trapped and convection is prevented. Our heads full of knowledge and fun we decided to set up a mini-greenhouse known as cold frame in my backyard. Then an argument ensued. Granduncle wanted to grow tobacco, I liked vegetables but niece preferred flowers while nephew loved fruits. Finally we cast lots and the vegetables won.
