grow out as many seeds as possible to avoid wasting your time in the future. even if you do get a female it doesn't mean that she is a good representation of the strain. to really get the best quality bud you must grow out 10-20(or more) females. take clones from each plant and label them. flower them all and pic the best 10-15 plants. flower the clones of these 10-15 plants and pic the best 5-10 plants. keep doing this until you have it down to 1-2 of the best phenos. this is time consuming and requires a good deal of space but imo the only way to continually grow "top shelf" buds.
