I grow from seed... say I drop the bean day one, see the neck day 4, eager sprouts by day 6 and then the first real set after the cotyledons maybe the size of half a penny by day by day 10 or 11. So it's almost two weeks since I dropped the seed, how old are they? ooooor when does week 1 start? with first veg nutes? with dropped bean? at sprout?
