Heres what i do step by step and always get 100%
First go to lowes/home depot/ace/walmart and pick up some peat pellets.
Cut your clone at an angle, make sure its around 4-6in. You want 2 nodes(where the branches come out) in the peat. Instead of cutting them off pull them in a downward motion so they take a little strip of outer skin with them(more rooting area) If your cut isnt right below the last node then re cut it there. Dip the clone in the schultz, put it in the peat pellet(of course after you have soaked them, and poke a small hole for the clone) Put the clone in all the way and sqeeze the pellets around the clone so its in good contact. I prefer individual humidity domes, get a gatorade bottle(or any clear bottle , gatorade are usually bigger. Cut the top off so you are left with a dome, put the clone on a saucer(you can get them for like 50cents at lowes or depot) or in a cup, then put the dome you made on top. Spray the inside of the dome with water, so can spary the clone if you want but it isnt required. I remove the dome once a day for freash air and i dont fuly remove my dome on until i see roots, just check the dome each day, if thee is no condensation on it then spray, if there is then leave it alone. you shouldnt have to worry about the pellet drying out for the first week but check anyways. If the puck feels light then just spray it down with your spray bottle. I normally see the first root a week later. Good luck let me know if you need any thing else.
