This is my first year cloning but it has been surprisingly easy. I just get clones and as soon as they have enough growth I start cloning. They just need enough to keep growing new limbs after you take your cuttings. Each time I take cuttings the plants bush out and I can get more and more clones. I just have a small 3x3x5 box with 4 double 4 foot flourescents. I am running 18/6 with 6 25W bulbs. The mothers are doing great. All are were purchased this spring from various co-ops. Between what I found and what I have traded for I have 35 varieties. I am cloning like mad and hope to keep all 35 types going until fall when I can decide which I want to go forward with. Then I will focus on keeping healthy mothers going through the year. I plan on planting all clone mothers the 2nd or 3rd week of May.
