I'm asking for others input on how long is the minimum, yet proper amount of time from pollen on-to foliar wash deactivation? I'd like to hear what others think on this one-thanks.
 
I often leave the plants overnight before spritzing them down with water to remove excess pollen...but have left it as little as 2-3 hours before and then spritzed the plants...if you do wash the pollen off this way, be sure to give the plant a bit of a shake and time to dry before putting them back under the light....if not then the droplets of water can act like little magnifying lenses and leave burn spots on the leaves...

I mix pollen anywhere from 1:1 to 1:9 ratio with cornflour ....it makes it 'go further'...only one pollen grain is needed to fertilise a flower...and the cornflower will also 'mark' the buds you have pollinated.

Well I can say that my 2 hour dwell time made many more wilted pistulas than the half hour I ran before. At 1/2 hour I say low fertilization had occurred. At 2 hours dwell time it was a near complete job. Thanks to TLBWP and corn flower also makes pollen much heaver and it drops to the floor/ground instead of floating on the air
 
you're welcome....another thing the cornflour does is mark the buds you HAVE pollinated to look at later with white smudges :D oooh...just re-read my post...I already mentioned that! muhahahhaa...

Pollination is immediate. So if your brushing on your pollen, by the time you brushed it on then you can spray... if your going airborne then sky is the limit... so your answer has variables... 1min for brush on, airborne when ever you think she has got it good...

It the same as sperm hitting the egg, once they meet game over, or should I say games begin... Once that pollen lands on the pistil your golden...
 
Ahh---runnin out of pistils--?? On the serious note I sure got a better count on 2 hours. My botany instructor did indicate that it's a few minutes until activation--then tubule penetration- after a few moments of that and then it can rain or be irrigated.

PS: when pollen absorbs water it activates and sends out a tubule that enters the pistil, then the chromosomes pass down the tube to the female ovum.

I just put the pollen in a freezer bag, tie it around the branch I want to pollinate and shake the bag to create a dust storm inside. I put another bag over the main body of the plant to protect it when I remove the first bag. Then spray it down till dripping to remove or deactivate the pollen. Usually leave it couple of hours before spray down.
