a plant will usually show sex(preflowers) at about 4-6 weeks from seed under 24/0 or 18/6 lighting. there is no need to switch to 12/12 to sex the plant. it will show in it's own time. be patient, this is not a hobby for those who are in a hurry. it is much better to wait til a plant has preflowers and alternating nodes before switching to 12/12. preflowers and alternating nodes show the plant is mature and will be able to produce more, better quality bud when flowered.
justaseed Reviewed by justaseed on . quick question ...i know u prolly heard this a million times but the faq section isnt working. as far as i understand a male plant has balls and females have white hairs(pistols) so my question is at what point in time of the plants growth can u tell wether its a male/female?
