Long time grower, new at cloning.
The first clone I ever took was in the mid '80s in late July when a katydid chewed through the stalk about a foot down from the top of a 6 foot plant outdoors. I finished the cut with my Buck knife, stuck the top in the soil in the hole next to an emitter and two weeks later it had doubled in size. I tied the two apart and had two in that hole.
Last year just to see if I could I took 6 cuts from a big backyard trainwreck plant, dipped them in CutnGrow, then into rockwool cubes soaked in tap water, then into a bluish/clear dime store plastic storage bin with a top, then set the bin in the shade between two large plants. A week later they had roots so I dropped them into gallon pots, after they had doubled in size I put them in soil on Sept. 1st. when I took out my earliest strain. By mid- October they were mainly one cola a little over foot long with a few side buds, about an oz. each.
This year my wife has taken over. She is cleaning up the lower branches of several strains in an indoor mmj grow, cutting with scissors, dipping in CutnGrow, into rockwool cubes soaked in tapwater, and into several of those dime store bins. The bins are set in the corners in indirect flourescent light in a room that stays at 78 degrees. She takes the tops off for a few minutes each day but doesn't add water or spray. She is getting roots in as little as four days. She is planting into 4" pots of soil mix, and virtually all of her cuts are rooting and thriving. From reading, I always imagined cloning as difficult. I am not finding that to be the case.
