I may be exaggerating but progress on the polyhouse has been painfully slow...

Never mind, Bladdy, you can't be good at everything.

[Chestnut]

Now I know why my ambitions don’t go beyond coldframe..
:-D

[MyWifesBrassicas]

It's quite a build, I'd love to build one when I get some time free

[Snoop Puss]

I presume it isn't meant to look like that...

What happened? Storm? Four-legged creature (if it were here, I'd say a wild boar) running amok?

[muck lover]

Looks like you’ve been eating Jerusalem artichokes

[Greenleaves]

I think Steptoe had one like that

[Baldy]

Getting there...







It's a build in progress people...

[veggiechicken]

Bladders, didn't you say its a marathon not a sprint. I think you've passed the first mile marker/

[Baldy]

Need to push the center up a bit looking at pic 2

[Snoop Puss]

Looking Bladdy brilliant.

[Baldy]

Getting there. Still need to do something about the dips in the roof. But, getting there
...

[Snoop Puss]

Looking really good, Baldy.

Is your corrugated material a single sheet across the whole length? Or several? Mr Snoop made me a similar structure once but with several sheets. Was very effective and even survived considerable snowfall until it all started to thaw, at which point all the snow slid towards dips between the sheets and then the whole thing collapsed. Looks like you've got a single sheet spanning the whole length, in which case this won't be a problem for you. But just thought I'd mention it.

I'm green with envy, by the way.

[Baldy]

Thnaks Snoop.
Its 1.5 sheets across the length (3 metres / 9ft)
I'll probably need to pad out the central supporting arches a bit more and (somehow) get up and release the fixings, add some silicone at the joints, then refix. Will probably end up with a little bit of sitting water whatever I do as the polytunnel frame is a bit warped.
Its survived some fairly heavy winds already so I'm somewhat confident it will be ok. You can never use enough pallet wood on a structure I think

[Snoop Puss]

OK. I guess if it snows a lot, you could just sweep as much of it off as you can, rather than letting it all glide to a low point as it thaws underneath due to the heat of the greenhouse.
