I have always liked cloning and have done both in the past but only would clone from a vegging plant to get a mother every once and awhile. I would always keep mother plants to supply my room because I read some years back that potency and yield decrease as you keep cloning down the line of clones. Is there any truth to this? A clone is supposed to be identical to the host??? I am constructing a grow space and would like to do some what of a perpetual cycle but would like to save space and energy not housing mothers. So from those that do one or the other, or have done both I would like to hear your thoughts.
