I'm not exactly sure what direction I plan to go with this thread, but there is info I have been looking into for a few days now, and would love to hear other people's input. If I start going into items that are common knowledge, I'd love to hear more details about them. I wasn't sure what catagory to use, I figure general is as good as anything. Recently I ran into a small Spider Mite problem, and ran across the idea of using Mighty Wash. If you spend a day like I did doing research on it, you will find a range of reviews on it from absolutely rave, to it being a total scam. If you look at the bottle, it basically says nothing. It doesn't really tell you what it does, but it does say something like 99.85% water, plus inert ingredients. It's a foliar spray that is supposed to be 100% safe I think even to drink, and people have claimed it eliminates mites. I personally used a bit of a pesticide on the mites, but decided to also use Mightly wash to give those bastards an extra kick in the ass and out the door. I know people use Mighty wash and PM wash on a regular basis, and I was thinking that is probably not a bad idea. It seems like the stuff works, and is a 100% safe preventative. The one serious issue to me was the cost effectiveness however. $75 is the price on 2.5 gallons, which was not enough to cover the entire grow I was working in. Say it would cost me $100 a spray, bi weekly or weekly sprayings would definitely not be cost effective. However I like the idea of being able to hose down my plants with something healthy and not have to worry about poisons around the room. This lead me to my search of trying to find out, what is in the stuff, and how can I just make it myself. It's 99.9% water, why not just find what the .1% is. Through a few hours of curious searching, this is what I think Mighty Wash is. I am also going to guess at PM wash, based on info from what I will link to a Youtube video I ran across. I am by no means a scientist, just an enthusiast who loves researching about this hobby, and also loves a deal. The following infomation is not fact, just my best guesses, and I will continue to research more. If people have more accurate infomation regarding the infomation I provide, please comment and let us all know. I don't know any of the science or chemistry behind this, I'm sure some smart guy will chime in with more details, but if you apply electrical current to regular water, you can seperate it into 2 parts, 1 being Alkaline, and 1 being acidic. This seperation has been done for years. People buy expensive machines to create the alkaline water for drinking for various health reasons. I did a PH test on Mighty Wash, and it was approx 9.1. It also has kind of a soapy texture, which initially led me to beleive that maybe it had a soap in as an emulsifier or something along those lines, like soaps that kill mites. I now beleive this is incorrect. When you seperate the water, 1 side would be clear acidic water, and the other a colored soapy feeling water. The soapiness is natural occurance of this process. The video below gives hints at all of the details I've mentioned, and basically also leads me to beleive Mighty Wash is packaged Alkaline water, and PM Wash is the acid half of it. I've personally never used PM wash, or been able to test it personally, so this is pure assumption. I do think I remember seeing a post about PM wash stating it was like PH 2.5, though I'm not sure. If all of my assumptions are partly or completely false, I'll still continue researching, and still attempt a DIY on creating these items. The first link is a complicated DIY that I would not be attempting, but provides details about the water seperation process, and the use of said water for plant benefit. http://www.youtube.com/watch?v=yap9cZIIjyA The second link is another DIY I found. This video was not for plant use, but provided the same type of seperation idea, and was a much simpler design. The video was unfortunately incomplete, however it had enough details to be able to create the device. http://www.youtube.com/watch?v=XiGB-JaRqF4&feature=related If my information pans out, then maybe we can easily make PM Wash/Mighty wash at home easily and cheap. I was also thinking of ideas of creating your own mixtures. Like what would happen if you add 5% neem oil. Or possibly mix other foliar sprays with this water. The possibilities are endless.
