I started a number of bulbs 6 weeks ago, mostly ~1" deep in pots indoors, under lights. Now I'm wondering if they should have been planted a little deeper? I'm using a very fast-draining medium, and the environment is cool. Several of the plants look like they should have been planted at 2-3" depth, since the top growth showed quickly and seems a little floppy. I've added additional material to some of these for support. This is my first time growing these-- I'd appreciate comments and suggestions. Thanks! --Rick Buell
