  • Moldy Greenhouse

    Evening all,

    This is my first post after casually browsing for a few months now.
    Last summer we purchased a small timber framed greenhouse (6.8x4.3). I would imagine the timber is pressure treated but it's not painted.

    Over the past few weeks as the winter weather is upon us I've noticed a significant amount of condensation forming on the interior glass. I've also noticed water droplets running down into the corners now causing blue/black mold. I had few cuttings taken earlier in the year with white mold forming around the base the of plants. I've since removed these to prevent further infection.

    Since these findings I tend to leave the door and vent ajarred to ensure good airflow and close it in the evenings. Despite these efforts this has not really helped.

    This may be something I have to live with and in my case an aluminium GH may have been a better purchase.
    I don't at present heat the GH, im not sure this would help with the condensation and mold (please correct me if I'm wrong). Treating the timber may be another option, is anyone aware of interior mold prevention treatments? (Ive read bleach can be used).
    I should add I don't have any mains power in the GH so a dehumidifier may not be an option. I have however, installed a small SVC powered fan to help with circulation.

    I'd really like to hear from anyone with similar mold issues and how they resolved/overcome the problem. I have to admit I don't like the idea of culturing mold where I grow crops, it may be something I have to accept whilst I wait for the warmer weather.

    Thanks in advance
    Tom

    Are you sure the timber has mould? timber changes colour when it gets wet, I believe it's called foxing. Got any pictures?

      Is water soaking through the outside wood or does it bead like it's got a protective coat? You can use some water repelling paint like this on wood-

      It's good to clean the inside wood with bleach to kill mould spores. Do you leave the vent open all the time? If there's enough ventilation at the top/bottom of the greenhouse night & day would it stop? I don't have a greenhouse but I've got a wooden shed with windows so it's kind of similar

        I get green algae in my greenhouse but not black mould - even my pressure treated benches are fine - posible ventilation issue IMHO

          Thanks for the comments, as soon as I get a drier weekend I'll take everything out and give it a good scrub. I meant to say I had a large tank of water in the GH which may be adding to the humidity.

            Try something like this to treat the mouldy areas.

            No Nonsense Mould & Mildew Cleaner 1Ltr | Cleaning Fluids | Screwfix.com

            or

            Barrettine Mould & Mildew Cleaner 4L - Toolstation

            Once rid of the stuff - keep things a bit more ventilated
