How long before i can tell the sex of a plant its been in 12/12 for 2 days

 

[TheLastJuror]

depends on plant..some show within a couple of days and others can take up to 2 weeks

 

[communistcannabis]

some sativas take even 3 weeks to show

how long if you do 12/12 from seed its been 22 days since they sprouted but they grow like their on 18/6

sorry i only have a pick form day 15 but better than nothing

 

[woolypudding69]

It all depends. Mine showed on day five, others have taken a couple weeks...sorry.

 

[northwoodsmoker]

sometimes up to two weeks but mine took a week to show the 4 males i got which sucked..

Unless it's a slower growing strain, that looks tiny for day 15.
Something might be slowing the growth?
I did have some purps that was tiny, and took forever to grow any size.

ya i agree with probo24 after 15 days you should be transplanting in to 3 or 5 gal buckets. More info like ph level, type of soil, nutes stuff like that would help. and mabey a strain if you know it. Just trying to help you not trying to be demanding. Peace, love and lots of green.

12/12 in case you didnt know from seed

 

[cbtwohundread]

depends on strain,and conditions in the growbox,ect.,.,usualy within a week or so

make sure theres no light escaping when its in the dark
after a few day after the preflowers come out that wen u should be able to determine the sex
