I usually toss mine at the 4-5 week mark but its strain dependent. Just check out you pistils. When those white hairs are MIA and changing on you your females should be good an prego. This Blueberry Diesel seed run I’m on now had such vigorous males I’m pulling a bit after the 3rd week.
If you let the pollen stay on the plant late into the flowering period what @Foreigner is getting at is that the plant will continue to produce new seeds but these seeds will NOT develop in time to create viable seeds.
If you pull the males out at week 5 of flower, then soak the female plant down to deactivate the pollen resting on the bud sites the plant can then use the remaining weeks to pump all that work and energy into growing big viable seeds.
I usually introduce my females at 3 weeks flower and then leave them until week 5 and do the soak. 2 weeks of plant fucking makes for a lot of seeds and some but not many to deal with sorting out afterwards.
Sorting through the run I just got done with didn’t take me too long luckily. Gotta find that quick efficient way to do it without having a seed sorter
THANKS for the replies, taking them down Tuesday, my next day off. Will wash the plants, didnt think of that although i do it inside hours after laying pollen .
