I have started using petri dished as seed propagation method. I use wet 100% cotton wipes as media. Here are the pros and cons that I have found: Pros: -Near sterile environnement -Easy supervision of development and disease -No weeds to make competition with the seeds -Saves space Cons: -Have to place in proper media just after germination -Manipulation of seedlings requires patience and dexterity -Roots may get tangled in the cotton Dont put too many though, I was surprised to get near 100% germination rate on D. dielsiana... From left to right, clockwise: D. dielsiana, D. spatulata 'frazer island', D. burmanii, D. cistiflora.

Interesting technique with the cotton balls. I've been using vermiculite for seeds and cuttings. Do your petri dishes come with the 4 quadrants separated or did you make plastic partitions? I've been using toothpicks to divide the dish into areas for different seeds.

The dishes come with molded divisions. I use vermiculite for bigger seeds (I. lutea, Sarracenia, etc.). I also propagate Ping leaf cuttings in vermiculite with these dishes, although I would prefer no divisions because of the size of the leafs. Where did you get yours?

My petri dishes are plastic and don't have any divisions. Active Surplus is in downtown Toronto and has an amazing range of all sorts of stuff. They have laboratory glassware, forceps, test-tubes plus everything else you can think of. The petri dishes are 50 cents each.
