Males will usually start dropping pollen around week 4, so I would move that male out of there right away. I just move mine to a window sill. They won't get real big but even a 12 - 15" male will produce plenty of pollen. Capture the pollen and then use a small brush or a Q-tip and dab the pollen on the female sometime around week 5 or 6. A fully pollinated female can produce upwards of 1,000 seeds or more. Instead of doing a full plant you might consider just pollinating a single branch on several females. That way if you get varying phenotypes, you'll have several to choose from. A single branch can easily produce 50 - 100 seeds.
