I give up. No - one more attempt.

I put two patio slabs on the bottom shelf. Holds it down a treat and still allows me to use the shelf.

I use a bag of gravel to weigh mine down; but does mean you lose a bit of space (although if you're careful in arranging the bag you can probably put things on top of it).

I realised this weekend that I might as well not have bothered with the "growbag greenhouse" i got from wilkos; have a growbag with 3 tomato plants in it but realised I haven't zipped up the front since the nights were consistently 10C... so they can't be getting any benefit from it... oh well!

The other problem to watch out for with this plastic greenhouses, especially in this heat is that the plastic can start to semi-melt at the top of the structure and stick onto the hot metal roof rods. Then it will tear a hole in it when you try to pull it off to remove the cover. This recently happened to me. Or condensation can form on the top metal rods and cause rust patches, which will also stick to the plastic at the contact points and tear it. I've wrapped some bent empty loo rolls over the top contact points as a temporary cure but really must get round to removing the cover and putting some waterproof Duct tape around the top metal poles where it comes into contact with the plastic cover to act as a barrier between metal and plastic cover, as hopefully this will prolong the life of my cover.

Yes, I had that problem as well :mad:

At the moment I think I will have to replace the present one anyway - cover ripped/melted - plastic bits broken beyond re-patching - metal bits rusting.

New one will be positioned and anchored following all the advice from this thread :T

Plus it looks as if they are now being sold with better quality covers.

Well yesterday was a weird day weather wise indeed! There was a heavy downpour at about 10.30am and when I looked at my polycarb greenhouse there was a pond inside - the drain in the patio had blocked and there was water everywhere.

That was quickly sorted with a poke of a stick and the water cleared and dried up in the sun which was very warm. The greenhouse door and vent had to be left open. Moving swiftly on to 1.30 and the wind picked up incredibly to the extent that it blew inside the door and ping 2 of the polycarb sheets out completely with the silver clips all over the place. Got them sorted and tried closing the door over but the temperature was over 40 so I had to open it up and the same thing happened again - 2 more panels flew out, but thankfully only 1 casualty it seems with a decapitated tomato plant.

Decided to leave the panels out until the wind died down and got bungee cords to hold down other panels. Just at that point one massive gust shifted the greenhouse over a few centimetres so then had to fill a tesco bag for life (available due to lifting a crop of very tasty potatoes which were had for Sunday lunch) with bricks and stones and put it on the end of the bungees to weigh the greenhouse down. That seemed to work!

Never known a day like that before, trees down, debris all over the place, and it was really warm. Not a good day for owning a greenhouse!

Well I have cleared a bit of ground (dug out two old shrubs:eek:) ready for a mini walk-in

However I decided to peg it out just to see how much space I needed to level - checked the height as well - and realised that the top will be about a foot above the wall dividing me from new and very nice neighbours.:(
Think I will have to speak to them before I order it. I know it's my garden but feel I should let them know.

Sorry to everyone who has also had problems - still it is a bit of a comfort to know I'm not alone.

It looks as if tying to a fence and sinking feet into ground with weight in the bottom is the way to go (so much for 'being ideal on a patio'!)

I do have a potential spot if I move something into front garden - after I make a space there :rotfl:

Mine is on a patio, it has six slate slabs leftover from my kitchen floor in the bottom after several blowovers

Hi, my greenhouse actually came with guy ropes and pegs to tie it down, was only a cheap one but obv one of the better ones. It wintered ok but has got a few rips in it, have used plasgtering tape to fix these and patched up the zip at the front. Really want to get a conservastory, so hoping to use this as a bit of storage too.

Ours came with guy ropes too!

It came from B&M and was 19.99.

We're really pleased with it!

So far I have not had these problems but I am glad I have now read this tread. It's a warning to me.
When I got my first one my partner said it would probably blow away in the wind. So before I put it outside he was thinking what to do to prevent it happening. I have it at the side of our garage, held down with a very large stone at the back of the bottom shelf. Still have some room to put things there. Then I got another and have put it next the the first again with a very large stone on bottom shelf. So far so good. But then I have only had them this year, they have not seen a winter yet. They can be left out over the winter can't they?
Partner suggested that they may need a bit of heat in the winter but being plastic I wasn't sure what to use. Then I thought of a couple of night lights on the bottom shelf, what do you think?
I am such a beginner with these things I know nothing
I hope you can get yours sorted as I am really please with mine up to now.

I left mine out in winter but without the plastic, I just used it as a shelving unit really.
