you still have 4-6 weeks for vegging and it'll take the same amount of time to ripen the flowers as it would if you had planted months ago...iow, expect harvest anywhere from mid-sept to end of nov, depending on your strain. they'll just be smaller...so plant more seed to make up for it. i planted up the free space in my garden on july 1st after waiting too long for some promised cuttings that never happened and they're coming along well. i don't normally plant this late but had no choice this year...i did learn tho to never again rely on anyone other than myself for stocking my garden! i had to plant direct in the soil tho to minimize the germinating and seedling time as much as possible but i still expect them to be around 18" by flower time.

might as well go for it and see what ya get...i am!

good luck
