My uncle and his partner been growing since mid 70`s and i guess one of them crossed Bluedream, honey bee, and jesus, and i managed to get some seeds from a bag that they used collidial silver on.They are real hardy nothin fazed them during topping or anything, they stretched so fast i didnt have time to do much training, i`m still new to this.and drooling over the plants that are 4 oz each, i got 1oz a plant last time, i`ve cut my light to 10 light and 14 dark for these last two weeks is that cool to do, it sure seemed to pop out more hairs when i did.
