From the advice in this thread I decided to use one big (about 5 gallon) planter per plant.

I'm planning on starting them out in standard 12 ounce plastic cups, inside, for about 2 weeks. The seeds I ordered are feminized so I'm hoping there won't be any males (or hermies). AFAIK I need to start them out with 18 hours of light per day, but since I have year round 12/12 , I'll need at least 6 hours of artificial lite. I'm still trying to figure out if normal incandescent house lites would work - maybe 100 watt bulbs?

During the vegetation stage on my balcony, I'm thinking I'll also need to add some artificial lite so I can control when they start to flower. I do have a lite built into the roof of the balcony that's right over where the plants will be - nothing special so I wonder if that will be enough.
