i don't keep mothers..and i do about 50 - 75 clones per month! if your are growing your plants in veg tke cuts from them before going into flower..i always trim my plants up taking cut from either tops of clones that are mature and ready to be transplanted or from plants gonig into the flower room....then ther is no need to keep a mother....i have found that it is easuier to keep unwanted pests away from the grow side by no using mother plants and doing what i call a perpetual grow! typically my clone trays will have 18 plants per 1020 tray and when they get tall enough i top them so just one tray gives me 18 cuttings and X 4 trays equals 72 new cuttings...pretty simple and no mom! :thumbsup:
