yep - 2" !
OK - I'll leave them where they are now, and hopefully they'll start
behaving. The Basil seeds which came up first are now leggy, the later
ones are not so - hopefully this move will stop them going that way.
The same should be the case now for the toms.
I'll keep the lid on the propagator to try and keep humidity and temp
up. I've been lightly spraying them every day so are moist but not wet.

Again - thanks for the help Sacha !
