how to use shallow plastic containers?

[antipodes]

At my work, we had a big clearout of teh kitchen, there are about 20 unclaimed plastic boxes of various sizes, I mean lunchbox sized ones. Many have no lids etc. I was wondering if I could put these to any use in the allotment? I was wondering if I could use them for some sowings, like lettuce, or flowers? Or as cloches (a bit small?)
I don't have a greenhouse and OH will go mad if more "junk" comes in the flat  ;D
Any ideas?

If they are clear, those you could use and covers over seedlings and cuttings..otherwise you could make holes into bottom (heated nail or something) and use them as seed/plant trays..perharps making cardboad divided as you would have yourself nice and deep 'modules'.. ;) You could grow some cut and come again salad leaves or herbs..coriander? But not being that big..you might want to keep them closer to home for watering for 'cut and come again' crops as they would need daily attention.
Or perhaps keeping them as 'picking berries' containers? Or deep 'saucers' under plant pots?

Could cut up for plant labels too.

Stick some wet kitchen roll in a few and pre-germinate peas and beans in them. It's worked a treat for me this year!

Yes you are right, I might just keep them for transporting things! It's amazing what people throw away! I thiink they are too shallow for cloches and too hard to cut up  ;D
