When it comes to gardening in colder climates, a greenhouse is almost a must have. It extends the growing season and gives the plants a lot more heat. With a greenhouse, we can actually pick ripe tomatoes here and grow some plants that we would not be able to without one. A greenhouse can also be a great place to hang out on those cool spring days and summer nights. When we started to look out for one to build, our expectations were very high. In a northern garden we have to deal with frost, nasty winds and hail, and also loads of snow in the winter. Our days in spring and fall don't have much direct sunlight so we need to catch every sunbeam we can. Plus, we live in town and the greenhouse in our small back yard needed to be somehow catchy.

This is fantastic information. Thank you Anna for posting so we can benefit from your experience!
ReplyDeleteYou're welcome, Fiona.
DeleteWow! This looks amazing! We aren't very handy around our house, unfortunately, but I still dream of putting together some kind of greenhouse someday. I never thought of making a dome-shaped structure for one!
ReplyDeleteTo have a greenhouse is a blessing, for sure. Hope you can have one soon, too.
DeleteYou know, I can not thank you enough for sharing this information. This is literally a gift to me; since you posted this on the exact same day as my birth day! I believe I know of the "pricey" e-book you mentioned and my gut had told me to wait and keep looking for the info. I needed to make this "bio-dome". Again, thank you. I would like to share this with others if you do not mind.
ReplyDeleteSo glad we can be of some help. Sure you can share it as long as you link it back to here.
Deletehi i cant figure out how to use the acidome web site i got all my lengths for my struts all ready cut but i need to find what degree angles i cut them at. and i cant seem to see it on acidome? please help i have been researching the internet for two weeks and i keep finding different answers and on your pictures i cant see what the numbers where.
ReplyDeleteI will ask my husband to answer you, hopefully today or tomorrow. So stay tuned, do not give up it was not as difficult.
DeleteHi Felicia, please have a close look @ the forth section of the post, particularly below the graphic 'How to use the Acidome.ru calculator'. This graphic shows an example of strut on Acidome.ru. The various numbers on the pic have an explanation below it. What you need to pay attention to are the #4 and #5:
Delete4. The value of a flat angle to the plane of the outer edge.
5. The value of the dihedral angle between the outer plane of the edge and the plane of the cut.
The key word is 'the dihedral angle'. Maybe this link to a sample pic will be helpful to see what it means: http://www.geo-dome.co.uk/cumbria/Photos/7m_scale_strutangle.jpg
In that graphic are shown dihedral angles between the planes with one common edge.
how warm does this thing stay in the winter?
ReplyDeleteIt totally depends what you cover it with. A single layer of greenhouse plastic poly keeps it 4 degrees warmer at night than the outside temperature. You also can cover the dome with double layer plastic poly filled with air or double walled polycarbonate panels which would increase the protection.
