Dear all,

I've planned to get a new greenshouse, which is the PE cover with DIY staging that sold in Wilko, also a 3ftx3ft coldframe to overwinter my newly potted plants. just a question before I can set both up--should it be gravel first then poly cover as the base to cut off weeds, or the other way round? I'm just wonder if i put poly cloth as base will the enclosed enviroment gets too condensed with trap water, also there might be slugs & snails's best hibernate places??

Thank you for all advise

Ping, I don't totally understand what you want to do but I don't think polythene is appropriate for under plants. you could use a weedproof membrane under gravel. that would let water through but not let weeds up

I'm not sure what you mean either, is it a GH or polly tunnel...

I think Ping has bought a small pe covered walk in Coldframe/green house type 

I would just weedproof membrane and gravel and keet a eye out for pests

I tried one of those soft skinned plastic greenhouses last year - due to lack of ventilation (only opening the door allows air to cirulate and disspate moisture) it was always dripping wet. I found slabs and decking helped but did not solve the issue of condensation. To answer the question then weedsuppressor then gravel and regularly opening the door is the way to go. Greenhouses are good for keeping the rain and frost off but they can get colder than the outside during freezing weather as the heat only builds up during the night and the cold air stays longer during the short daylight hours of our winters.

Hi ping, if it gets really cold again this winter, you can keep it a little warmer at night by filling a few 2 litre plastic pop bottles with hot water before you go to bed and placing them on the floor directly under the most tender plants.  Water retains a lot of heat and releases it fairly slowly.
