I have been threatening to grow tomatoes for several years and have finally planted some.  Now for the funny part:  I was shopping at Home Depot and my son found a little kit to grow some.  It consisted of a metal pail, seeds, dirt and mini gardening tools.  We planted, and now we have approx. 20 little seedling in this pail!  My question is at what height do I separate them?  I really do not have a well soiled place to plant them outside so was thinking of doing a few in planters.  Any suggestions on this?
TIA
