I took a plant and flipped it as soon as it had it's first set of leaves (3 prong) because I really wanted to try the strain and I already had a plant that I was getting ready to flower. It went surprisingly well and I got a lot more weed than I thought I would get. I am not sure exactly how long it was above ground but don't the first set of leaves kinda start the clock on veg time? If so then it went straight into flowering after being a seedling.
