I want to know if their is another way to figure out your plant is female or malebesides putting it into flowering ( 12-12). will putting it into 18/6 reaveal pistills or a sac??? any answers would be great...thx

there are two ways to sex a plant. the first way is to let it grow in the vegetative growth phase until it reaches sexual maturity, i.e. forms preflowers. the second way is to force flowering before the plant is sexually mature by moving to 12/12.

Do u know how tall or how long on average before it reaches maturity??

I grow with the dutch method using seeds and 4"pots (12/12 as soon as they break soil) and can sex them usually after 2 weeks. For the first two weeks I nute them with a home made brew of iron (for the stems) and rooting hormone to accelerate root formation....this way the plant is "mature" enough for flowering right away.
I have a brother in law entimologist with a phd who swears he can sex seed by looking at them...

Here's some info....not sure who wrote it so I can't give credit.

From literature it appears that the growth of a male or female plant from seed, except for the predisposition in the gender chromosomes, also depends on various environmental factors. For growers who are well experienced, percentage of female plants is 60% - 90% female, but less experienced growers can end up with 100% male plants. The environmental factors that, according to literature, influence gender are:

- a higher nitrogen concentration will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a higher potassium concentration will give more males (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a higher humidity will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- a lower temperature will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- more blue light will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- Fewer hours of light will give more females (at the three-pairs-of-leaves stage and continue for two or three weeks).
- In later stage, as you increase the light, the plants grow faster and show more females/less males. Sixteen hours of light per day seems to be the best combination, beyond this makes little or no appreciable difference in the plant quality.
- Another idea is to interrupt the night cycle with about one hour of light. This gives you more females.
- Spray dilute Fish Emulsion ( 1 tablespoon per gallon ). When the plants have three sets of true leaves, plus the top sprout, give them a wetting spray of Fish Emulsion. Do it once a day for three of four days. Top and bottom of the leaves.
- To achieve 100% female plants is to expose young seedlings for several hours to an atmosphere of Carbon Monoxide. It doesn't hurt the plants, but it could kill you.
- Treatment of hempseed with ethylene gas will increase the resulting number of female plants by about 50%. Ethylene is produced by certain plants (i.e., bananas, cucumbers and melons), and these can be used to treat hempseed in a simple manner. About two weeks before you plan to sprout the seeds, place them in a paper bag or envelope and put that in a plastic bag with the peels of a ripening banana or cucumber. Replace the peels after a couple of days, and change the bags to prevent mold

Males are taller and most times stink more than females. Don't quote me on this. If you grow the same strain more than a few times you will get better at picking out the males. If you have a plant that is suspect male. Let it go for a while. By the time you definitely know that it's male it will be showing balls and will not have pollinated any female plants.
