Marijuana Sexing
After four or five weeks you will start to have a chance at sexing the plants. Although generally considered one of the trickiest parts of growing your own marijuana. Marijuana sexing is quite straightforward and will become easier as you gain more experience. The reason for sexing your plants is so that you can remove male plants before they have a chance to pollinate the females. If this occurs the females will start to develop seeds and this will divert their energy from THC production.
Left to their own devices plants will develop pre-flowers after around 4 – 6 weeks. This is the right time to remove the males and commence the flowering stage.
Marijuana is a dioecious plant which simply means that the males will produce pollen and the females will produce seeds. Although, as in other forms of life, hermaphrodites do occur.
Flowering is the only true way to sex your plants, although you may get a clue from their growth patterns. Male cannabis plants tend to be leggier than female plants with a longer internodal length. Female plants are squatter with more leaves and a bushier aspect.
Male pre-flowers should be clearly visible to the eye, although a magnifying glass will make your job easier. Male flowers form at the junctions of the branches and stem and the pollen sacs form little balls.

Female pre-flowers will also form at the junction of branches and stem but will normally start to form at the fourth or fifth branches up from the base. They are easily distinguished by the appearance of pairs of tiny white hairs, known as pistils.

Some growers force flowering by changing the light cycle before the appearance of pre-flowers. They then watch their plants closely for the appearance of flowers and remove the males. However, others believe that this can stress the plants and is not a proven way of speeding up the process as plants forced in this way may spend longer in the flowering phase, cancelling out the advantage.






and how long will the female plant pre-flower for for 2 months of what
IMHO you’ve got the right aneswr!
Very true! Makes a cahgne to see someone spell it out like that.
Can a plant have both sex growing from the one
Stock? First timer had some with the seeding buds,
So had the things called pistons aswell.little confused.
Please someone help
do you grow both sexes or if its a male you kill it .. i only have one plant …can i still grow it and enjoy it …
You can grow a male marijuanna plant but the seed development takes most
of the THC production and of course crystal production, if u are only growing one and its male, save your money on nutrients and lights and toss it in the garbage. Sorry
Thanks guys for helping me getting my plant to grow right in my room and. All the information was exactly on point and every thing on my end result I had 15 pounds of marijuana grown right in my room but the odor was a problem but I used link lots, lots, and lots of baby powder when any body click me down.
after smoking some weed that i bought i saved the seeds that i pullout from the buds and i’m trying to plant them , so my question is will i be able to grow a plant out of them and have buds and smoke it someday ?
or i have to buy female seeds ? ( honestly i cant buy any seeds coz in my country no one sell seeds :S so if there were a way to have my own plant and buds just by growing seeds that i pulled out from buds i will be very thankful if someone would help me do that)
Hi Creepy Mind.
You can certainly grow the seeds from your weed. The only problem you might face is that you will not be able to be sure of the sex of them. If you end up growing males and females together, then the flowers will set seed. But this has obvioulsy happened to your weed in the first place being as it has seeds in it!
Plant them and see what comes up.
some 1 help me i stated 3 weed plants and 1 of the stems broke and i took the step and put the stem that was still on it back in the dirt and its still growing and im just germanated the seeds about 2 weeks ago and i just water it and try to keep it under light and 1 of the plants that grew about 1 inch up from the 2 leaves the plants stem is abot 3 inchs long and it keeps slumpin over and i put a pencle next to it to keep it up but it acts like its dieing please help i cant get mericle gro or plant food what els can i do to help it grow
i have planted seeds i got from my stash n the are flourishing, 4 weeks from seed now, I have no idea what type of plant or length of growth cycle. I was planning to have atleast a 8 week vegetative stage, then reduce lighting to 12 n 12 to begin the flowering stage, does this sound right and about how long is the flowering stage.
Where do i get the seeds to start up? and how do you know the diference of male and female seeds?????
Hi First timer
Sounds about right. 8 weeks might be quite long in the veg stage, depends on the strain, a lot of plants really stretch during flowering so if space is an issue at all I would think about switching to 12/12 sooner. If you’ve got lots of room then let them go the 8 weeks and count on somewhere around 7-10 weeks for the flowering stage to finish.
Don’t forget to change your feed to a bloom formula.
