when you first take the cuttings put them in water until your ready to submerge and cut your 45's. I found that when you clone with plugs, rockwool, or soil you need to have your cuttings in a terarium of some sort. they wilt do to losing water as a natural process of making food. Your best bet is to buy/make a bubble cloner. when your plants are in a bubble cloner they tend not to wilt as much and in my opinion root in half of the time as the aboved mentioned. So............... here is what I do............I pick what branches I want to take off for my cuttings. I then place them in water until I am ready to cut them into lil babies. submerge under water and make your 45degree cut. Take out of water and put it in rooting hormone. put it in your plug and let the bubbler do the reast. In about a week you have lil babies to have fun with. Or you could judt take your cuttings as instructed and place them in a glass off water with the stem submerged, change the water every few days and 2 weeks or so later you'll have clones. But if your using plugs dirt or rockwool just follow the cutting procedure and place them in a humidity dome and spray them often. the key is to not have them lose their water 90% humidity was ideal for me. Keeping them warm is also one of the most important things to do. get a heating pad for your clone setup.
