I also used the Tiresias Mist, just spraying the very top of one branch, the whole limb ended up being full on balls, it was loaded. I'll post a pic when I can of it. As soon as I saw the sacs start busting open I cut the whole limb off, put it in a jar of water and then periodically shake the pollen and balls sometimes, off onto a glass plate, then scraped up for use.
I'm not a professional or a scientist, but what worked for me was to spray the top once a day, right before it starts showing sex, for 10 to 12 days. Sometimes, maybe 2 or 3, I would spray it twice a day, once in am, once at pm, (when lights came on and before they went off), I did this at about a week in.
And I've done it this way 3 times and had success all 3, so it's what works for
me
