If you leave it be, it will pollinate your girls. This is negative because once a female is pollinated, all her energy is diverted towards making healthy seeds instead of fat nasty buds with tons of THC and resin. :jointsmile:

If I were you, I would just cut it down and kill it but if you want to keep it alive for whatever reason, at least move it out of your grow room. There's really nothing positive that can come from having a male unless you are breeding.
