Wow. So now I can take cuttings of plants from seed just before flip and store them untill I sex the originals then only root the cuttings from select females or males I want to keep. This saves me a lot of hassle considering my limited space since I only want to clone females with danky traits. Your knowledge is boundless farmers!
...another option would be to top the unsexed seed plant and take that top and just stuff it into a moist cup of coco and stick that into the flower room, some will die this way but most will root and display sex without taking up any space in the flowering op.
...oh, and back when i ran my high-density micro-SOG i routinely kept my cuts in the fridge and had friends deliver cuts to me in baggies, much like SeaMaiden described earlier in this thread, except i just keep a small bowl of water at hand so i could soak the paper towel and then wring it out, after which i arranged it neatly in a rectangle laid over the palm of my left hand so i can then lay a bunch of cuts down, fold the rectangle up and over the cut ends afterwhich i roll that damp papertowel up, wrapping the cut ends, and stuff it into a ziploc baggie and into the chiller drawer at the bottom of my fridge.
...i've also done his for just this reason too so that i didn't lose genetics during a move in my case.
peace, bozo
