Let's say hypothetically you grew 4 plants, and about 5 days into flowering you find 3 males and 1 female. Hypothetically, can you use the males to make hash or anything, or is it still young? If these plants existed , I'd say they're around 6 weeks old.
You are not growing MJ are you!? Because doing so is illegal...hypothetically! PS: You can use any sex plants if there is enough resin - hypothetically!
