12/12 should not affect female to male ratios.

if this were the case, it would be a common occurrence in Equatorial growing areas, where photoperiod year round is 12/12.

I've not seen female to male ratio affected by 12/12 indoors from the beginning either.

if you want to avoid males at all costs, find a nice female, mother her and grow from clones. or fem seeds.

peace!

I've never understood why people post that growing conditions affect the gender of the plants. Things like: more red light -> more males, 12/12 from seed -> more males, etc.

AFAIK, and Like Dr. King said, the gender of the plant is predetermined from the moment there is pollination and the seed is created. And it's the pollen that determines the gender of the plants, similar to human sperm (XY sex determination) or with other animals.

Otherwise the methods of creating feminized seeds wouldn't produce 100% female plants from those seeds. They just wouldn't work that consistently if growing conditions were involved in determining sex.

Hi everybody I need some input from you guys who have all grown malawis in the past. I seem to have two phenotypes of Malawi as you can see from the pics, one short and bushy to the left and the other very stretchy with super thin leaves and branches in the background.
Looking at these two you would never guess they are the same strain and they are both 63 days old 12/12 from seed. My question regards the stretchy one in the background, is this normal at 63 days to still have hardly anything at showing on it or have I just lucked out and received a dud seed ?
Any input would be much appreciated.

The one in the back looks like a sativa and its normal to develope buds slowly as it is a 100% sativa the others look like sativa/indica hybrids, are u shure u didnt switch seeds by mistake?

They are both 100% pure malawi

exactly!

Did a 12/12 from seed with northern lights x blueberry did not have sufficient ventilation tho was a closet grow with a 250w HPS topped this during flowering bad mistake then mainlined ended up with two nice heads and lots of side nuggets because of insufficient ventilation and clustered buds had some bud rot in some of the middle nuggets forcing the plant into bud from seed causes hemaphrodite tendencys had one poor seed was NOT exposed to any type of pollen! 50%Perlite 50% premium soil mix. Total from Germination to harvest was 89 days.total yield was 215grams dry weight I think topping while flowering did have its problems e.g slower growth and smaller yield than what I could have got but was a good learning curve !

yes, exactly my words, a plant from seeds needs to mature and show sex BEFORE it will be flowered, its most prob going to hermie otherwise!
a good indication they are ready when shoots start alternating!

I've been very curious with this method, so I decided, why not give it a shot with some freebies I have , saludos Mexicani-ar

Nice frostiness

I grow 12/12 from seed with Sativa's.
