I took my first clippings to clone for sex 11 days ago. The first thing I did was label each plant with a letter. Then I put labels with letters on the side of the rows of the clone tray I am using. I cleaned a shiny Swiss army and Leatherman scissors with alcohol. Based on everything I am reading here and Jorge's info I took clippings from the best looking lower branches, they were about 12 to 18 inches long and the stems were about 1/8" to about 3/16" thick.
I took two clippings from each plant in case one clipping fails you still have one that you can sex from. These branches were not fan leaves, they had 6 or 7 nodes on them if you include the new leafs that were just beginning. I clipped them at the stem then cut the clipping in half at 45 degrees. This left me with about 4 nodes at 6 to 8 inches long. I then clipped the leafs of the bottom two nodes off , cut the top leaves in half to reduce transpiration, and placed the remainder of the clipping into a glass cup of prepared Willow Water.
With two clippings in the cup I then moved to the area I prepared with the clone tray. The 10"x20" holding tray had about 1/4" of rock pebbles that were bathing in water, the insert clone tray sits on this such that no water can reach the cone shaped clone plug receptacles and this has a clear dome top that stands about 8" high with two ventilation holes that you can open or close. All of this sits on top of an old heat pad, for medical purposes, set on low heat. I turned the heat pad on about two hours prior to starting and it was already fogged up. Since this was my first time I was trying to be sure that I was giving the clipping every chance to survive and grow roots. With this in mind I also had a cloning gel and some rooting powder. I took the clippings from the Willow Water and then dipped them in the cloning gel using a shot glass. This works well and allows you to roll the clipping around while tilting the glass using a small amount of gel. I then rolled the clipping in a rooting powder and stuck the stem into the prepared hole of a rapid rooter plug that had been soaking in Willow Water. I did this procedure for each plant that needed to be sexed. After all the clippings were in the cloning tray I used a very good mister and sprayed the clippings from about 2 feet away just enough to get them moist, not soaked, and then covered them again with the dome.
I took the leftover leaf clippings and put them in my shake using my Vita Mix blender for a very nutritious breakfast.
Every day I check them about 3 times and I exhale into the vent holes about 4 breaths each time.
I have misted the clippings about once every three days, I have not directly watered the rapid rooter plugs other than the initial soaking as I described.
It has been 11 days now and I see roots forming just above the rapid root plugs on several of my clippings. They are all still green, no yellowing, though a couple seem to be browning at the stem but, besides these I would say I am on my way to a 90% to 95% success.
I will follow up later once they are in soil and vegging.
I hope this helps. I don't use photos or numbers so the NSA can't provide any info to the DEA - Believe that!
