Try using those clear plastic covers from pots of dairy cream etc. over the top of plant pots which have seeds germinating in them. Look much better than plastic bags and they work.

Ha ha budgie ;D.... It wazna me...... but still it is a good idea. I use the plastic tops of Pringles myself. ;)
I use the big ones (big yoghurt containers) for drip trays for little pots too :)
