or will they just blow away with the first strong wind?

[too many girls]

i had one similar to that, it blew away and all the metal buckled

I grew my first toms. with a plastic greenhouse like this. The base of the frame was pinned down with long metal tent pegs that went through the bottom of the frame. I've got a similar one that I may use as a back up if needed this year. The original lasted two years before holes appeared due to the suns rays. I think that you get what you pay for.

I think that if it's for starting/hardening off seedlings then you are better off making a cold frame. Few bits of polycarb type plastic, or old windows and a few planks of wood and you are away.

plastic greenhouses are very flimsy, but some people do manage with them. It depends on how sheltered your garden is.

coldframe it is then!

Theres one on our site and its been there all winter   it must be well strapped down.  I got a small one :Pand as long as its sheltered in the garden its great for helping get by.

Just bought one, strapped it ownand seems to be doing ok, finger crossed

I bought A cheap plastic greenhouse of off ebay for £50 (5ft x 6ft )
Its on my allotment, i anchored it down with treated wooden stakes. 2 per side.
to make it more stable in winds, it was a bit flimsy. i attached garden wire from corner to opposite corner on the diagonal. Hope that makes sense.

It stayed up throu the winter with no damage

I bought one last yr to go in my back garden. I put my seedlings in it and it did a ok job.

Have found over winter the plastic has gone hard and brittle so it has ripped very easy around the seams.  Wilkos do sell a new cover for £5 which i have bought. so be prepared to buy one of these next yr. I suspose this is why they sell new covers.

Hi, all , i bought one of the wilko greenhouses last august....thing blew over in october with the strong winds destroying around 20 trays of herbs   however due to cost of new glass houses now i decided to persist this year and have ensured the poly tails are tucked under the frame and added around 20 extra 9" u clips to pin it down. big issue i find with them is lack of a ventilation flap (or window) which means very difficult to control temp and or humidity

[BostonInbred]

I wieghed my down with two 25kg bags of gravel.

I also found that the plastic went brittle over winter. Ive patched mine up with the remains of a clear plastic raincoat and a tube of pvc pipe adhesive

[richie370]

i find its hard to weigh down to many bits of push in pipes  etc ....the other thing i forgot to mention is that since rebuilding i have used string to create a netting structure all round reducing the risk of the pipes lifting out of the brackets ...... took a while but after last years cost definatley worth the extra hour and ball of string 

[digalotty]

i have just got a 6x4 reinforced green type for £33 from homebase 
will do for the plot

NNNNNNNNNNNOOOOOOOOOOOOOO The silly shelves inside fell down today due to the wieght from all the seeds, some plants have broke and died but most look ok, it wasnt the best thing that I wanted to be greeted with returning from school after finishing for a two week break. I was real happy but then really annoed. Oh well, live and learn

[Lardman]

Oh well, live and learn

We've all done it - This was mine 2 years ago.
