not sure if this is the case with you but i had the same thing happen, germ good, planted and nothing happen for a while, turned out for me that it was to cold were i had them cause thats what i thought and when i raised the temp in the room they sprouted within 2 days
im not sure about the difference of how the smoke is goin to be yet but ill let yall no, but i started a soil and hydro of the same seed at the same time and the dro is about twice as big as the soil
i have one auto on 18/6 and one 12/12 so ill let yall no how much of a difference in yield there is, cause i been hearing how much 12/12 will decrease the yield in autos, so i thought i would just see how much difference there really is
