Hi Heabow, my advise would be, go onto an internet auction site.

Decent glass greenhouses i've seen sell for £80-£100...much,much cheaper than buying new and your recycling too.

Some i've seen require the buyer to dismantle, some sellers offer to help you dismantle.

Yes I have seen those offers on ebay, but I am not able to go and dismantle a greenhouse and then have to transport it...

We have had a small plastic greenhouse this year but it is very small and wanted to consider something a little larger and being able to do more with it.

Our last greenhouse came from B&Q. The largest of their 'cheap' range of aluminium framed houses (8x10). It came boxed and complete and Mg and I assembled it ourselves in a couple of days. I have no complaints about it at all.

I bought a self assembly one from Gardman on the internet last June. I have cancer and it took me about a week to assemble. Somebody had to help me complete it. But it is the best thing I have ever done. I frequently plant seeds with the intention of making sure that I am going to outlive them. With great success so far.

Hi Heabow and welcome to GoY buy the largest greenhouse you can fit into the space as you will rapidly find you have filled it :-) As Bulba says we erected our 8 x 10 greenhouse over two days - just be ready for the odd rude word whilst your are building!

How do you find those plastic greenhouses? I was going to try one and see how I get on before I shell out on something more 'permanent' - just for tomatoes etc in the summer and over wintering some tender plants.

To be honest the tomato plants grew very well and there was a lot of warm humidity and a lot of snails and slugs, the amount of tomato crop was slow in appearing and overall I would say that there was not enough direct sunlight entering the structure even though it was facing directly south so I ended up with a lot of small green toms and very few ripe ones!.

The plastic was not clear and I am not sure if that made a difference or not. Also it was very difficult to regulate the temperature as it gets very hot during the day in direct sunlight.

I did also have cuttings and grew plants from seed and they grew very well.

I'm still trying to decide on a 6' x 8' polycarbonate greenhouse...???
