I would suggest that a good place to start is to decide how you will be using the GH. A super coldframe like mine, a cool GH, a temperate GH or a hot GH for orchids and such like. Usually the desires have to be balanced against space, and money constraints (initial outlay and maintenance). SIze is easy. Just figure out what size you think you need and double it. :-) bloke@silicon-north.com (Bill & Chris Loke)[Z4/5 on a good day] The Lokeation, RR#1, Kars, Ontario K0A 2E0 Elderberries have more fun than younger berries! -----Original Message----- From: zacwinic@mail.netnitco.net <zacwinic@mail.netnitco.net> To: gardeners@globalgarden.com <gardeners@globalgarden.com> Date: Thursday, January 07, 1999 3:32 PM Subject: Re: [gardeners] green houses Hi everyone. I hope everyone is enjoying winter. So far, we have been really hit by the snow. I am hoping the kids will have a full day of school tomorrow. We have had 2 snow days this week, yesterday and today they were on a 2 hour delay, and I pulled them out of school early yesterday because the weather got bad again. Anyway, on to gardening. I don't have a greenhouse, but some day would like to have one. We have seen kits in Menards, and kits in various catalogs. Does anyone have any pointers on what makes a good greenhouse, and just general tips? thanks, Holly holly zone 5 zacwinic@mail.netnitco.net
