c&t--
if they have 'balls'----PULL THEM
have you ever dated a 'red head'??
look for the little ""fine-fine"" hair next to the node/stalk....
......if it looks like the fine fine hairs on a redhead below her waist then your golden!
they will sometimes be crossed....not to be confused with curly pubic hair
they should be showing if their 3-4' tall-
google plant sexing and see some pics ...i dont know how to post pics
if your friend had them inside first and then put them out they may not be acclamated to the light
....what was the cycle he had them on before he put them out??
--or they been out all season? (some folks veg inside for height and thro them out at the last few weeks for flower)
did he plant them that tall or were they small and grew that high?....if so they should be showing somthing-
sex your plants under a garbage can before you plant them.....put them under a can for 12/12 and they will show sex within 21 days from seed
i have seen cuts\clones flower/hermi many times outside from different stress induced by the enviornment ...light ...shade...clouds...
even larger plants outdoors with lots of bottom shade can spit a seed(s1)
just think fine hairs....any 'balls' terminate with extreme prejudice --
if they still seem like they are not showing ....thro a tarp over them for 12 hrs of light only....give it 7-10days (?).....they will show
if not watch them closely and dont let those pollen(balsac) open and spread their goodness
make sure to look at each one from top to bottom....
......they may have hairs on top and balls where you cant see them ....examine each node branch carefully next to the main stalk-
any half hair\half balls pull them out and put them on 6&woodward--(hermi)
