what i do, when i want to keep a plant for later but have no room for clones, is take a few cuts, wrap the end of the stem in moist paper towel, put it in a big zip lock bag and store it in the fridge in the crisper drawer for a later date. they usually sit in there about 2 months before i clone them, ive heard they can stay good for around a year in the fridge. works great. i have some plushberry, br x dpd and wifi cuts in the fridge right now.
