    Default Propagators and their proper use?

    i don't use heated ones, cos i am always worried i will fry my seedlings.
    However i would like to ask how long you leave the lids on yours .
    up until this year i have always left them on as long as possible, until the seedlings are touching the lid, however i am wondering if i am doing it wrong, should i be taking the lid off as soon as the seedlings are up?

    I use a heated propagator, as soon as the seedlings appear i take them out and put the next batch of seed in.
    I found if they are left in the propagator they get too leggy

    I would be hardening off the seedlings a bit by removing the cover in the day, depending on the surrounding temperatures. Also the light levels are often better with the lid off than on. Night time I would put the lids on if it gets a bit cold. It would depend where you had them I think.
    As far as frying, I did this to my busy lizzies seedlings last year in an unheated propagator. They were in the greenhouse, in April. It was a dull day, I didn't open the greenhouse, or think to take off the lid of the propagator. The sun came out, and when I got home from work the soil in the propagator had that horrible baked smell, and the seedlings were totally cooked!

    I could not live without a garden, it is my place to unwind and recover, to marvel at the power of all growing things, even weeds!

    I'm using bean pots from wasabi. They each hold around 8 seeds. I take off the plastic lid as soon as must of them look like they're growing. I have them on a chest of drawers next to a sunny windowsill and radiator and so far every single seed has grown, even aubergines.

    they are indoors so warmth is not really a problem, hence not having heated ones, ambient temp is always 68+ as for light once they are up i rotate them on sunny windowsills so that they don't get too leggy.

    I always kept the lid on for moisture reasons, but I figure after being on here a while this could be more of a problem than a solution.

    i have just raided my stock of plastic takeaway ( chinese) trays, i have hundreds, and figure these will make nice little mini propagators, two inside each other, one with holes punched so as to act as a resevoir, and one upside down on top as a lid

    I sow my seeds into 3" pots and just cover with a small poly bag. I whip this off as soon as I see the first signs of germination. I think a bigger worry than the cold is getting mould or damping off so I make sure they have plenty of fresh air.

    I don't sow much this early though

    this 'damping off' thing is why i asked, i never really knew what it was till i came here, no it seems it has been my problem all along.
