I hate our throwaway society, so was considering collecting the see-through plastic cups from the water cooler at work to use for rasing seeds.  Has anyone tried this, and does the transparancy, help, hinder, or have no effect on the roots?

[WG.]

Should work just fine.  I use soft drinks bottles and they are clear.  The roots will avoid the light so technically will become potbound earlier.

Keeping the pots in an opaque tray / box of some kind will negate this.

coffee cups from mc donalds are ideal we use the lids for little propergators.

A neighbour works as a gardener at some local major national gardens obtained about 3,000 3" pots for me many years ago and as only a few have disintrgated, I keep re-using these every year, but all the plastic cups from the school discos, etc. that my wife helps out at go in our recycling rather than landfill.

Thet will be fine, just remember to chop a hole in the bottom

we use the clear strawberry containers for little propagators. and they are fine.

[SkipRat]

I,ve sown leeks, cabbage, cauli,s and beans in plastic cups and they work great. Just remember to provide drain holes.
