Here is a tip:  My wife and I quite often buy tubs of fried rice from Tesco (but any supermarket will do).  When finished with, they make lovely little propagators with lids.  We have used them to start onion seeds and, more recently, cucumbers from seed.  Every little helps!  PS.  Much snow in Hampshire this morning.

I use the trays that contained mushrooms,   they are usually black or blue  holes in the base by soldering iron.  I can usually find a clear plastic lid from some other food.

Cheers,  Tony

Yes, re-purposing this sort of thing is a great idea... snow here in Berkshire too !

When I saw the title I thought you were oing to grow rice plants

Here is another one.  Once all muffins are consumed (not long in this house!) you have a nice propagator with lid, measuring 20cm (w) x 15cm (d) x 12cm (h).  Recycling - don't you just love it!
