Hi SpanishFly ...i would like to add some more info ..if you dont mind ...that will boost your experience up even more
& everyone else that doesnt already know these things
first of all the sex of a cannabis plants is determined on the point of fertilization , by XY chromosones inherited by the male
then upon early examination of premordia flowers...that dreaded cats claw ...is a male ...magnify glass is recommended ....buttttt if growing conditions have been perfect for that variety ....& the male is male from genetics & not an environmental sex alteration
the male stretches just prior to showing flowers & always has further nodes then the female .....& i better add something else important here .....a sativa pheno is always determined by its leaf & flower (bud) style
for the unexperienced that may confuse the signs for a sativa pheno
also a female will always have thicker , stronger & most of the time longer branches at a faster growth rate than the male ...they got to support all the weight of the buds !
the female usually shows her premordia pistils from the 3rd calyx that developes ....so from the first sign of calyx development....which sometimes is extra leaf growth (shoot actually) ...dont start freaking ..."what sex is it" ! ....be patient
sooo if all these things have been examined...then you can start pulling ..start breeding seeds or smoke /make hash from male leaves
peace John
