Yes, they do. They are generally much slower in the initial weeks. So make sure to water according to plant size and not a pre-determined schedule based on your normal Cannabis plants. If you want you ABC to be the same size as your normal Cannabis plants, start them 6-8 weeks earlier, in order to reach sufficient size. From this age their growth rate significantly picks up speed.
During these initial weeks, it's best to fertilize them with only half of what you would provide for regular plants to avoid nutrient burns. Pre-fertilized soils often contain sufficient nutrients.
Also they tend to be more bushy and branched, with far smaller leaves compared to normal Cannabis.
