the only thing i can tell you is you must check them everyday (late mornings is best) and remove ALL male flowers....this will help keep them from filling the buds with seeds...also, i would recommend tossing any seeds that you do get from this crop as they all have an increased potential to "turn" on you if you do grow them, thus ruining another year's harvest. good luck, you've got some really nice plants there-can't wait to hear how they smoke!
