So here's what I have learned using males, just use and take cuttings in the same fashion as a fem. A dude can be smoked to help determine potency...if you care. Honestly you have NO idea until progeny has been grown out. And there needs to be a number of varieties to hybridize. Reason for this is simply to determine what/if anything valuable, will be passed on to progeny.
NOT very helpful I know but it is a very individual evaluation that is required for a solid male.
haha all of this is only relevant when you plan to use him again.
Peace
