I did this last year on a Snow White lady and it worked really well for me./QUOTE]
I bought all the autoflower feminized seeds one famous site has (most sprouted in 1.5 days!), and sprayed them with colloidal silver made according to this thread.
I got pollen from all, but a very tiny bit from the AK47. I made the mistake of spraying it twice a day like they recommend, only sprayed 2 branches, wanting to save the rest of use. And I kept spraying too long.
I did the same with lowryder. I started both too late, it was already showing female parts. But I didn't keep spraying the lowryder as much, so I got a little more pollen (just a pinch of it, which I mixed with rice flower to use).
But from the rest (amnesia haze, blueberry, northern lights, super skunk, and white widow) I got a huge amount of pollen! I started them earlier, and stopped spraying once I recognized that they'd gone male.
The trick is, spray the whole plant just before it's going to show flowers (when it's pretty big and the new growth is slightly different looking). Spray just the outside, you don't need to spray inside. New growth on the outside is more than enough.
Eventually it'll be covered in the unmistakable little male pods, just like they show in images on the net. If you catch it before any female parts show there will be no signs of female parts on the top. Inside where the spray doesn't reach, you'll have female parts. So what? Lowryder gave me a couple of clone seeds because of that. And there's going to be so darned much pollen as a result of this, you won't even want to collect it all from the center.
I tried the cutting off a branch. It's too much trouble. Just wait until the little pods pop open and grab them with firm tweesers. You can pick them earlier if you like, such as when they have brown stripes and seem about to open. But there will be so darned many popping open once it matures, you'll permanently forget about being impatient and grabbing them before they open. At first you'll only get a couple and worry, but eventually a day will come when you collect as much as you could ever need, in one session.
The colloidal silver made according to this pages instructions never burned or harmed any of the plants, except where I went nuts spraying 2 or 3 times a day. Then it only caused some distortion or silver coloration on the leaves.
I hear some people just let the pollen fall on something, but I was doing 6 at the same time, and had to make sure there wasn't cross mixing.
One more thing: That disolved solids meter doesn't work right with colloidal silver. I would reach 50ppm, then decide to water it down to 30ppm. I'd calculate the amount of water, add it, and it would still measure 50ppm.
Works great with water though, calcs come out perfectly (like trying to lower disolved solids in fish tank).
So I know it's not the meter. Don't believe the meter for colloidal silver, maybe just go for the yellow/brown color?
