I've read that online colloidal contains additives to keep it stable. Also, some say it tends to burn leaves, giving the impression colloidal always does that. If you make your own, it won't burn leaves. After a couple of weeks of spraying some might look a little unhappy, but it'll be the...

I tested 2.0V DC for a day. At 2V you do indeed get positive electrode burning, although it's slight. And of course you get the electroplate formation on the negative terminal. So with DC, you can avoid the electrode burning if you are below 1.5V, but you can't avoid electroplate fuzz losses...

I must admit, the 1.5V was 3 times faster than the 1V and both still had annoying electroplate fuzz on the negative electrode. I thought the 1.0V was better because it was the lowest voltage that would make colloidal in 3 days. But the electroplate fuzz isn't significantly better. Maybe...

Just be sure not to be lazy if you spray only one branch. For starters, it's hard to do. If you're trying to protect the pot so you can smoke it, you'll need to isolate that branch, and it's enough work that you'll likely not spray as many times a day as if you could spray the whole plant...

I go for anything above 14ppm. That density has only a hint of yellow color in it. I've used 50ppm too, but it's unnecessary. Rather than PPM however, I believe the dollar store laser pointer is the best indicator. If you can only see the beam in the dark, it's still too weak. If you can...

I tested 1.0V again, thinking I'd get no electroplate growth, as there was for 1.5V (see pic). It was still there. Less, but still too much. Perhaps when I tested 1.0V at first, I kept examining the results, measuring the PPM several times a day on my desk at work. Perhaps that produced...

Wow, that's a nice strain. The bud I just saw looks like the "give me the strongest you have" pot I got at a legal store here in California, last week. One problem with autoflowers is, even the best (like amnesia haze) are still not as covered in trichomes as that 303.

Yes, I see that now. There's a good article on the web about it. I made the mistake of following several other articles, which had you mix the STS first, then dilute the mix when you use it for spraying. According to the article, once mixed the solutions are only good for a month. Unmixed...

Just a choice. Maybe if I'd had better results with it, I'd say it was the only way to go. But I discovered, it starts to wear out once you mix it. Not sure how long it lasts, but not years. I stored my batch in the fridge and in a plastic sprayer (possibly 2 mistakes). Worked great the...

Followup: An experienced member of this forum said he uses 1.5V with a bubble stone, and gets very good results. I retested 1.5V. I had forgotten why I decided a lower voltage was better. Although it doesn't produce electrode burning on the positive terminal, the losses due to silver...

Mine's 9999 silver wire. I tested this again over the weekend, and didn't get electrode burning at 1.5-1.6V (a single AA cell). But left completely unattended with no vibrations and no bubble stone, it produced electroplate crystals on the negative terminal. A lot more than I expected...

You don't get any fuzz at 1.5V? I'm going to retest that voltage then. My 1.0V method still takes 3 days. I'd like to speed that up.

Yea, I read that too in multiple places. But I've grown about 54 autoflowers now, nearly all from cloning seeds using colloidal. I never saw a single one go hermie, except when I kept it for weekks past it's normal ending. But that's a bad thing! I'd rather have a few pods grow and make...

Here's the results of my testing for making colloidal without fuzz and electrode loss. I'll just put the pic here, but I started a new thread with a full explanation. You can make trouble free colloidal that never needs attending until you are satisfied with the strength.

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...

I have a hard time believing that little amount of silver could cause harm when smoked. There's silver in dust we breath all day. But, no one's likely to study this scientifically. If you try BHO for 20 years or so, be sure to report back what happened.

Tip if you don't like wiping grey fuzz from your electrodes while making colloidal: The fuzz is called, "burning" by the electroplating people, and is a sign the voltage is too high. It forms on the positive terminal only. They use something closer to 1.5V. I can't remember precisely what...

Yes, I've done it a few times. However, if the colloidal is weak and you don't spray long enough, or wait too late to start spraying, you'll only get a few piddly pollen pods. And maybe too late. So make sure the colloidal is fresh, has enough color to know it's strong, and spray the heck...

AK47 will do that. But it's a long time till it does. And colloidal is so easy to make. Did anyone else know you only need the silver wire on the positive terminal? So if you have 2, you could double it up on the +. Not sure what you'd use for the other terminal, but as long as it's metal...

Nice Ruderalis! I love those fat leaves. They're perfect for floodlamp style bulbs. I just checked my distances. I have 6 plants (the limit here). Most are 9 inches away when the plant is that size. But if it's a baby, I keep it a lot further till it gets some real leaves. . There's a...
