Greenhouse Condensation

My Cedar framed Greenhouse is now stuffed full of cuttings and overwintering plants and Iam concerned about the tremendous amount of condensation inside. Any advice or tips on how to reduce this would be welcome.

    Increase the ventilation during the day - even leaving the door open on fine days until the ventilation has cleared.

    paraffin heaters produce a lot of condensation. I think that electric fan heeaters are best at reducing it, and ventilate on warm days.

    It's not a mess, it's a nature reserve.

    Mine are condensating without any heating, I just open doors etc. on dry days, regardless of o/s temperature, I think better cold than damp. Don't think there is any answer as plants will give off moisture, as well as GH  condensating. So it's back and forth to GH. image

    Iam going to give it try keeping the door open on dry days. I hope I don't lose any plants to the cold weather. By the way some insects or catopillers are eating some of my Pelegonium cuttings leaves but can never find the blighters, they must only come out at night.

    If it's caterpillars they will be on the plants all the time.  What does the damage look like?

    And they will leave little poo pellets that are a give away...maybe it is Vine Weevil.

    I have found that opening the vents and doors during the day helps condensation. Insulation (bubble wrap) does help - at least it stops it dropping on the plants. Since I put tin foil on the floor of the GH that has also helped reduce condensation in my GH.

    I have tried to upload photos of my greenhouse to illustrate some of my problems but can't seem to add the relevant pictures when trying to insert from the photo icon.

    Megga, there are people on this forum who can help you;(sadly I am not one of them); start a new thread about your probs with photos.

    Megga, what device are you using to browse the forum?  Photo's also need to be less than 1MB in file size.

    A trowel in the hand is worth a thousand lost under a bush.

    Hi All

    I'am currently using my iPad to upload photos is this the problem.

    I've got a good sequence of pictures installing my dwarf wall Greenhouse which I wouldlove to share with everyone. Plus easy, strong, durable shelvinconstructed from CLS timber.

    Also I have put guttering all round the Greenhouse with a down pipe connected to an unwanted wheely bin behind the GH  place on top of 4 layers of bricks, left over from the dwaf wall, behind the GH so not seen. I've placed a scouring pad down the outflow pipe to collect fallen leaves, which is working perfectly.

    I've always thought rain water is best for plants and seedlings but I read in one off my Gardening Books this is not so. Can anyone explain.
