They should be ok, but starting a plant out door mid summer is hard, u got to water a seedling 1-2 times a day tell shes big or she will burn (around here). Mid summer the only place i plant is a cornfield. they water em an the other corn gives you shade.
In july they wont be very big at a month old an start to flower, they will grow in early flowering a bit also so I would guess shell be 2ft tall. Like a clone in 12/12.
