I've got a few Drosphyllum seeds and am planning to germinate them soon. I understnd that the Slck method (double pot) is one of the popular approaches for them. So I am turning it around in my mind to use a 32 oz plastic beverage container and cutt out the bottom. And then I'd put a smaller pot in there so it rests partway down, providing drainage and a couple inches or so above the tray. This way I could keep it "open tray" in the sense that the larger container would be in the tray and the bottom of the smaller pot would be above the water line. Whaddya think?
