How does the flowering time of a female affect seed development times?

From what I understand seeds take 6 weeks to fully mature from pollination.

Does this mean if pollinating an 8 week Afghan you would pollinate on week 2?

Or would you pollinate at say week 4 and flower the plant 2 weeks longer than you would for bud?

If you were pollinating a 16 week Sativa would you pollinate at week 10 or could you pollinate at say week 4 and just chop the plant at 10 weeks to extract the seeds?

The main reason I ask is because I’m thinking about doing a repro of a long flowering sativa and I’m wondering if I would have to actually finish the plants or if i could just wait for the seeds to mature and chop at say week 10.

You dont have to wait. There are a couple fully formed seeds on mine at week 4 on the stem bracts. As long as there are enough pistils/ anthers.

Nothing says you can’t let an 8 week strain go 10 weeks before chopping.

As for the sat, just pollinate on week 4 and let it go its full 16 weeks, or whatever the flowering time is.

Someone on here said wait 4ish weeks into flower to pollenate. From my research, to get the most amount of seeds, the pistols should be white and sticky. You want to pollenate just before the pistols start to brown.

If your just making seed for fun, my plan is to pollenate a couple lower braches as soon as the pistols are developed. That way the seeds finish in time with the rest of the bud.

If you wait for max seeds, you’ve got to wait for the seeds to finish. But you’re probably not using a max seed plant for smoke anyways so what’s a few extra weeks for another 1000 seeds

Soo, its a 16 week Sativa , what will be the timing right before the pistils brown? Please reread the Op and attempt to address the question properly. Try to form a proper answer to the Ops question about timing the pollination of a long flowering Sativa that he does not want to run full term. Please strive to keep quality of advice on the highest possible level due to novices and other members looking for good advice.

That i don’t know. I would think each plant is different. But I’d imagine if you start to see pistols turning brown that time to pollenate is asap.

Yeah I basically want to reproduce a long-flowering sativa without having to wait for the bud to finish.

It’s a fairly rare genetic I wanna reproduce and make maybe a few hundred seeds. My plan would be to also include a fast-flowering female plant (probably Lebanese) so that I could make F1s that would be faster flowering but also reproduce the long-flowering sativa itself so that I could run those genetics pure when I regain the patience.

I probably should have been more specific in my intentions upfront instead of posing the question without context.

Basically what I’m asking is if I can make seeds from a long-flowering sativa without having to finish the buds and it seems from the responses that that is possible.

Could probably try making some hash with the immature bud anyways.

With the utmost respect, if you dont have considerable experience with the question at hand there is no reason to answer . Answers placed here are forever and looked at years from now by people seeking advice. Thats should be looked at as a privilege and responsibility, not as a chance for an offhand comment.

Pollinate as soon as you see enough pistils / stamen. Wait 6 weeks and get your seeds. Good luck!

I second with Hashy on this one it happens to me a couple times out if the year.Ive found lone seed pods at around week 4 from stuff that got hit that had pistils you could barely see.If it can produce a pistils hair it can get knocked up

From my research you are correct on it taking 6 weeks to fully develop seeds and same with your analogy on an 8 week afghan. As far as the 16 week sativa it really depends on if you’re looking to harvest buds or seeds and either one of your scenarios would work. If you pollinated the 16 week at week 2 of flower, around week 8-10 the mature seeds would just start falling to the ground from my understanding.

I’m on my first attempt at a breeding project so this is only from personal research and I’ve attached supporting litterateur from a trusted source that has helped me along my entire grow journey thus far. There’s a lot of false information floating around on all the cannabis related forums and you used to have to weed thru a lot of bullshit to find some truth back in the days. We all make mistakes and are all here to learn and further develop our skills and craft of cultivating this magical plant so I really wish we could all just get along and correct each other when needed in private instead of just being dicks about it. Just my two cents on the matter.

Peace everyone!

Theres your answer right in the Original post. Good luck !

That doesn’t answer anything lol it’s missing the proper punctuation, so I’ll fix it. “ I’m wondering if I would have to actually finish the plants or if i could just wait for the seeds to mature and chop at say week 10(?)*” have the day you deserve my dude @Hashpants

I disagree, its very clear in the Original post he is running for seeds.

I like to let the plant go past when you would normally harvest so the seeds are starting to fall out on there own, that’s how nature would do it and the longer they are in there the more energy reserves they have for storage and strong germination.
