Greenhouses and footings

[veggiechicken]

Have you checked the diagonals to make sure that they are the same measurements? If they are its a problem with the window/framework and not with the base.
(I think that's right!!)

If you measure corner to corner you should have the same measurement which would tell you if it was square or not. I would of and have secured my frame to 4" x 2" treated timber and then secured that down to the base (concrete flags) once it all lined up. That way it's easier to move take up if required in the future.

So still undecided

I have taken the paving up. I have been looking at Rhino greenhouses. Thinking 8x8 foot now. However still undecided about the footing. Rhino apparently don't need concrete footing. However what is meant by firm flat ground. I was going to dig some hourse manure into border and place greenhouse will be and then flatten the greenhouse base area by walking on it a lot. Is this sufficient for a Rhino greenhouse? Has anyone had experieince of this? Does the ground settle and damage the greenhouse?

Or shall I just lay a 8x8 concrete base for greenhouse? Otherwise my friend recommended concreting a base just under the greenhouse edge. This sounds god, but like a lot of work??

Well it`s end of year one for me, the greenhouse(s) was successfull, I managed to get me another 8x6 glasshouse for FREE! my favourite price of course, this was fixed to some heafty pieces of wood, not quite sleepers which I wood of preferred...pun intended..t`was cheap I know. But it worked, I fixed an auto vent to this one and it worked very well, the only thing was the Tomatoes, I had mixed and strange results, the greenhouse produced bigger fruit earlier but the plants eneded up scortched, whereas the poly greenhouse the plants grew very high and quickly but the fruits where later and not so many, hmmm yes toms need sunlight I know , but how much? I suppose I should have white washed the glass, but I did leave it all a bit late. Next year I will be trying a greater variety of toms and Strawberrys, I also intend to build a bigger 8x8 poly greenhouse...free of course.

If you can get hold of some (free) debris netting, it makes effective shade for a GH.

If you can't get debris netting then try your local charity shop for net curtains.
