How to continue a strain through seed
So you bought some seeds and you want to make more seeds without any interference from another strain? That is easy. Just make sure that the male plants and the female plants are together from only the same strain batch. Do not introduce another strain into the pack. If you only have Silver Haze in your grow room, then all you need are some males and females. By letting the males pollinate the females you will get Silver Haze seeds. But you will loose some of the features that the original parent plants had in the selection of offspring, unless the strain you got was an IBL.
