alot of erroneous info here. pluck em as you find em. they will first be at the main internodes before the bud site, and later right in the crook of the node at the budsite. if u do a good job u can get 90% of em. if you dont, than you will get seeded. if you do, you will not get seeded. good idea to spray em once a week with water-not under the lights- to nuetralize any male pollen that may have shed. I spend alot of time plucking balls and rarely do I get seeds, maybe 1 out of 4-5 zips. see 'em, soak'em, pinch 'em.I started flowering about 3 wks ago. I was happy to see all the white hairs. But now there are some balls also. Should I pinch them off or just leave them? I wouldn't think it would hurt if I did. It's the only plant.
