Ok,, I do not think I made myself clear here.. People have been known to keep the same mother alive for 5 years with out ever taking it to flowering stage,, hence, never knowing the sex of that plant. The only way I can see this to work is kind of like throwing dice,, pick your mother plant, take clones, let clones mature, if male, then you know mother is really father.... hahaha.. so they all must all die. Not everyone clones then flowers that plant, some people keep the same plant to clone from for years.
