the number of seeds is more dependent on how many male flowers open AND how far into bloom your girls are before you pollinate-- and not really the # of days / weeks in 12/12, since each plants bloom-rate in 12/12 varies..
IMO-- best time to pollinate is when the female has a dime-sized "puff" of hairs at a bunch of nodes, and the male has a LOT of opening/open flowers.
IF you have other plants, take the "breeders" elsewhere for 3-4 days (all they need is a 100w CFL to keep em going) and shake the male onto the female every day as he releases more pollen.
Before you return the female to the 12/12 room with other plants, spray her down well with water in the shower 1st to remove any un-used viable pollen.
Every calyx has the potential to become a seed-- so the more hairs/calyxs she has, the more seeds you'll get. BUT: If you wait too long to pollinate, the seeds may not be mature at time of harvest...
Also remember-- once pollinated, MOST of the time the buds will be smaller and fluffier-- but still very smoke-able!!! We've had gals that we seeded give us a couple hundred seeds (or more) at a time, and still give a couple decent OZ's of bud.
No need for revenge, just sit back and wait.
Those who have hurt you will screw eventually themselves; and if you are lucky, God will let you watch!
Through What we create- we are immortal.
