I am here in the wonderful state of Colorado! In response to your questions here goes. First of all I prefer to take a cutting from a plant in the vegetative cycle. In my cloner they root within 7 to 10 days. Mothers keep growing and growing and so yes space is a factor. Most people I know usually purchase a grow tent and keep their mothers in those however they can be pricey. Mothers are kept between 5-7ft and this seems to work well for me and other growers here that we network with in our co-op. Hope this helps. I have an e-mail address you are welcome to use also [email protected] GOD BLESS and good luck.
