Males DO produce TCH. They just don't produce as much as the more desirable females. IMO growing a male for anything other then breeding is a complete waste. Yes you can make hash out of some good males but I would ask why someone would waste the space and electricity to grow it when they could chop it and start over and hope for a female. Not to mention the risk. (the law doesn't make any distinction between the sexes). So I would say that if you're only growing one plant and want it for smoking then yes you should chop it down and start again.

Yes a clone from a female will be female.
