On my first grow of 12 seeds, 8 sprouted. After planting them 6 grew. Of the six 3 were males. I had all the rookie problems. First tried using 4 200w cfl’s, latter changed to led’s. Then I fed them to often and got some burn. I let them dry for to long before watering. After all that I managed to yield two and a half ounces. With my next grow I will try auto’s. I am 70 years old and don’t use pot, but I love to grow it. The smell is fantastic! Can’t wait.
