Thank you, that is the answer to my question.yes you can use the tops of your plants for clones
you can flower her anytime depending on what size you wanna end up with. personally i put mine into 12/12 when they reach 9-12". Usually end up with a 3 foot plant depending on strain. I also don;t take my cuttings until they've been in 12/12 for a week or so. The stems are thicker and root faster than the weak, flimsy cuttings from a plant in full veg. Did I mention I use hps from start to finish ???? Yuuup. Gotta MH but HPS makes for a fuller, stronger plant.I'm growing from seed, meaning, i have to wait 6 weeks before i can cut clones. Does this mean i have to wait 8 weeks in veg before i can flower?
