Rick, I've wrestled the idea of using gravel for years. I think it's 'the cats meow' as far as the benifits, but the problem I have is I that I dump/spread my pot soil back into the garden when I'm done pricking out the seedlings and I try to keep the gravel to a minimun. I use gravel on the bottom of my pots but thats separated by a cloth barrier tucked downward with a putty knife, so when I tip the dry pots I can quite easily make two piles on a tarp without too much intermixing. But, gosh, it's great anyway, even if one has to end up with a mix pile sometimes.
Yes, I've got quite a few started this year. Aside from the ones here, I've got six more pots at my daughters place (she wanted to get involved--a great flower gardener). Three of those are from some older dwarf white seed I got from Buggy that I thought I better do something with. Now I'm glad I did since she's back on line and I'll have as many as she wants.
Those seedlings in the margerine tubs will have to be set out next spring. Assuming there's 50 between the four tubs at 6" spacing, that's a 25 foot row. Figure a good foot break in between batches and end borders, its probably end up about 30' of row space.
