Tired of wiping fuzz from your silver electrodes? How come we have to do that anyway? I wanted to know. Turns out the fuzz is called, "burning" of the electrode by the electroplate people, and is an indication of a voltage that's too high. I tested various voltages to see if I could make that stop. I wanted to just let the machine sit there unattended, and make colloidal all the time, without electrode loss from fuzz. That loss can wear out a wire in 20 uses or so if you run high voltage. Here's the bottom line: 1. Higher voltages (up to 30V!) are only needed because people want to make colloidal in 1 day, and tend to make a giant mason jar of it. 2. If you reduce the amount of water to what you really need, like 150ml, it gets made much faster. So you can lower the voltage. 3. Voltages below 1.0V either don't work, or take too long. Voltages above 1.0V will make fuzz on the positive terminal. Not sure where the precise sweet spot it, but 1.0V works well. Unfortunately, you can't use a single AA cell, that produces about 1.6V when new. You need a resistor network to make 1.0V. 4. There's 2 types of silver loss. Fuzz, and crystals. Fuzz forms on the positive terminal. Crystals are from electroplating, and form on the negative terminal. That's ok, you can switch terminals and transfer the electroplate back and forth from one electrode to the other. But some crystals float, so even with no fuzz, there's still a very tiny loss of little crystals. Nothing to worry about, it's extremely small (see pic). 5. AC also stops fuzz, although there's still a tiny amount of electroplate crystal formation. But in a 150ml beaker using 24VAC, it takes more than a week to make strong colloidal! 6. With no silver loses, you can use thinner gauge wire. If you use thinner gauge, you can afford to buy twice as much. In the pic shown, there's 24 inches of silver wire in the AC version. It was cut in half, and spirled to fit in the beaker, using pieces of circuit board to keep the wires from touching. 7. You can't use 1V on the double spiral electrodes because it's 1 directional, and the tiny circuit board pieces needed to keep the wires apart will bridge, and you'll end up running 300mA though the wires. But fortunately, AC doesn't bridge the gap. So you can make colloidal all the time, without having to tend the machine. Use 1V with your straight electrodes, or 24V with the spiral. 1V takes 3 days, 24V with spiral electrodes takes 12 hours. (To make 150ml). 8. There's a really good sprayer at CVS drug store. It's for hydrogen peroxide to spray on your cuts, but it's the ideal size for 150ml, and a VERY good sprayer. Better than the ones I purchased separately. Spray away and make seeds! Easier to spray the whole plant than a branch, so just grow 2. Soon you won't be paying $10 a seed.
