Seedlings and Tray Covers

Hi all,

I'm planning on sowing some seeds soon. I was wondering if anyone had any advice on whether or not to use plastic covers for seedlings in trays (for extra warmth/humidity)? I've used them previously but had the problem of fungi before (perhaps there is a way to avoid this?)

Any advice would be great! Thanks

    I keep them on until the seeds germinate, then take them off to reduce the humidity.

    You can get plastic tray covers with a sliding ventillator so that may be your best bet.
    Alternatively, the basic tray covers do help but you have to ensure that you remove them every so often - particularly if you see signs of moisture starting to build up.  Or you could wedge the covers a few mm's to allow some air flow.  It's a fine line between keeping your seedling compost just moist and it becoming too damp and causing damping off.
    Best of luck this year :)

    Don't use them any more. Most of them eventually cracked, they did encourage more mould (even with the ventilators), and it was a faff to take them off to water everything. If you can afford to be patient, you don't really need them for most plants.
