How long does the OG #18 take to flower? How tall in flower was it? I have headband which is Sour Dieselx OG Kush and just love it but it takes sooo long in veg. Seems like I have grown out 2 plants to her 1 plant.OG 18 yields great. I have grown it probably 5 times and I easily yield 1 gram per watt with it. It is great weed too. I am smoking my last bit of it right now. I retired the strain though to make room for other strains. I also don't plan to run feminized seeds ever again if I can get away with not ever doing so. The 18 does seem to hermie a bit every time I have grown it but I never notice. There is very little seeds, I notice about 10 seeds per crop on average but there could be more that I missed.
