I bought my first mini sinningia this summer, SRG Blue Pearl, as all as my first micros, speckles, freckles, conccina, etc, from several vendors. I am experienced with speciosas and had a feel that the micros and the minis were very different. So I asked for tips and OMG, the micros and the minis are different! I have being harvesting tip cuttings from my micros from the many crowns they produce, some of these cuttings were the size of a lemon seed! And root them and now have a trillion micros growing, how long will it take for tubers to form from tip cuttings? I did the same for my mini and now have tons. Sinningias don't go dormant in my weather, soon I will saturate the market. I am having a hard time killing them, too much water or too little water or too much light or too little light, no luck!
