Some Tips From the Pros
I've searched the internet for as much information as I could find on using STS and working with pollen. I found a few pieces of information which some of you may find helpful. The first two are mine.
Trim Everything But The Top Three Nodes of Each Branch
You want the plant to focus a lot of energy on perfectly formed flowers. Trimming off all of the undergrowth (before starting flowering) will make this happen. Trust me, you will get plenty of pollen. ;)
Doing this reduces the possibility of mold and other problems. This also means, at harvest time, there's nothing to stop the fall of pollen except some branches.
Spray Every 5 Days
All over the internet you'll see people recommending spraying a plant and tossing it in flower and only a few say to spray it again after 2 weeks. The rest of the horticultural world says STS is effective for about 5 days in a plant. The rest of the horticultural world sprays every 5-7 days.
I spray every 5 days. Starting 5 days before changing the lighting to a flowering schedule, spray the nodes of the plant every 5 days until 10% of the flower pods are open and dumping pollen. (Once the last spray is dry, lay out your collection trays, parchment paper or foil)
Pods Which Won't Open Can Still Be Viable
Spraying every 5 days, the pods should open well and dump lots of pollen. Should you find a plant which grows pods and seems to quit, right before opening, you can still harvest the pollen. Clip the pods off and dry them in a low humidity area or dessicant chamber.
Over a piece of glass or parchment paper, rub the pods across a stainless steel mesh, like this small fine-mesh kitchen strainer. Pollen will drop through the screen, along with small bits of pod/plant matter. You'll also end up with plant matter which will not go through the screen. Rub until you're sure you've rubbed the majority of the pollen through the screen. A small brush comes in handy to clean the screen of pollen.
Dilute Your Pollen With Toasted Flour
When pollen is mixed with toasted (and cooled) flour, it greatly reduces waste and helps contain the pollen when using it. Using straight pollen is wasteful and adding flour greatly increases your chances of spreading the pollen thin enough for full use. Adding flour also helps keep pollen from floating around the grow area, pulling it to the floor.
Toast 50 to 100 times as much flour as you have pollen in a dry pan over medium heat. Let it cool. Thoroughly mix your pollen into the cooled flour. I like using a stainless steel pan, becuse pollen and flour slide effortlessly across the bottom. Once it's completely mixed you can pollinate your flowers
