Why does everyone dispose of the males?? Separate a male from the female(s), let them grow until they begin to flower (not bud, but actual flowers), then harvest them to make butter. I call it "boy butter" and it gives you a really nice, looonng, mellow buzz. Slather on toast and enjoy an hour or three of mellowness.
If you are going to pull it and pitch it -- which is such a waste to old timers like myself -- then you can only reuse the soil if you allow time for any of the remaining roots to dye off, etc. Let the soil bake in the sun for a week, then add new soil and nutrients to it, mix well, bake a little longer, THEN you can use it to supplement. Don't just pull the male and repot a female into the same container. Ever.
Hiramklarke, you might need to eat some of that toast just about harvest time! Given your anxiety over sexing your plants, I can't imagine how high your anxiety will be when it comes time to determine harvest date! LOL Good luck.
