Okay, people have tried innovative ways of germinating seeds and propogating leaf cuttings. I have been using plastic pipette containers, with hinged covers, as "grow chambers". I have had good success with it. Others do essentially the same thing by placing media in a baggie and sprinkling seeds or emplacing leaf cuttings. Others still just use a container with water.
I have another twist on these methods, a hybrid, if you will, from my experience with drowning aphids. What about getting a container and filling it with one's favorite rinsed soil media and then overfilling it by a couple inches of water? Then place seeds or leaf cuttings on top - WITHOUT covering the container. How about letting the water level recede, naturally, and allowing seeds to germinate and distribute themselves in perhaps a more uniform manner, taking root in the media when the water level recedes to the surface. Does that happen in nature?
