Wow , awesome man , Thanks

This is great thanks Spurr. I too am a jean us I have a triple digit IQ as well. It's zero zero nine.

@ all,

Thanks for the kind words. I'm glad you find this info interesting and hopefully you have success putting it into practice. As I wrote on page 1, I know it's a lot to take it at one time, so maybe take your time and watch the video a couple of times(?). I know once people understand the underlying principles the rest is cake. It's really very easy to use my methodology, but it does require a few extra steps ... thankfully those steps are easy as pie via use of the three calculators to do the hard math for us

Ha. Well, considering 100 is the average IQ of most people, I think you're a little below average

This is a lot to take in lol I have homework to do.

Alright man by next year (January) I will finally have a tds meter and order everything I need. I will figure this out eventually. I know it will be worth it.

but should I stick with perlite or go with sunshine mix? With sunshine mix, do you water with plain water every other time? obviously I would use ro water and add all the different acids and sillica, but not add any nutrients? as long as the ppm and ph is good?


I know these questions have to be getting old man but when you look around and read, everyone has a different answer. I just have started to trust yours more than others.

Ingenious on using the Bru'n water to find out alkalinity. I always wonder if brewing and growing could be combine...now I have my answer

Thanks. However, I didn't try to find a beer brewing application (such as Bru'n Water) on purpose, I would have if it had dawned on me to do so; I just got lucky. I spent about a week searching the Internet for an easy to use citric acid alkalinity calculator on my Uni's databases, Google, Ixquick and DuckDuckGo search engines, to no avail. It wasn't until I used Bing search engine that I found Bru'n Water ... and I am so very glad I did find Bru'n Water. The main problem was my choice of search terms.

Before I found Bru'n Water I started getting pretty frustrated, and I even contacted UNH to ask one of the authors of Alk Calk if he would expand it to include citric acid (it already does the math for nitric acid, sulfuric acid and phosphoric acid). Lets just say I got a cool response (and not the good "cool"). However, once I told him I work in the field of plant physiology on medical cannabis* he really got unfriendly (and he's boarded by medical cannabis states in Main, Vermont and soon Mass!).

* When I e-mail or call academics at a University, College or corporation, I tell them I am a plant physiologist and consultant working with medical cannabis. And 99.9% of the time they are interested and end up asking me about cannabis and medical cannabis application, etc. The funny part is, more times than not I end up teaching them (about cannabis), not the other way around ... cannabis is great

I can do the math to find effects from citric acid, as is used by Bru'n Water. However, it's a major PITA (I'm not keen on lots of math) and I doubt more than a handful of people would have been able/willing to use my methodology (had i not found Bru'n Water). That is why I felt I had to find an automated calculator for citric acid, and thankfully I did find such a calculator.

I am also going to check out "EZ Water Calculator" (https://www.ezwatercalculator.com/), it too is free, however, Bru'n Water does exactly what is needed so I am satisfied at this time. However, I may hack Bru'n Water to provide only citric acid calculations. I plan to contact the Bru'n Water author and ask him if he would be willing to do so, or if he would mind if I did.

I am thinking about making a simple spreadsheet that includes math for citric acid, phosphoric acid, sulfuric acid and nitric acid. Basically, I want to merge Bru'n Water and UNH Alk Calc into one spreadsheet. Extracting from Bru'n Water should be simple; and I have the study used to create the math (from NCSU) that UNH later used to create their Alk Calc (in conjunction with NCSU). I am an acquaintance of a couple of professors at NCSU, so I can shoot them an e-mail if I need help with the math.

I'll answer you more completely soon, but for now, the potassium silicate isn't part of my methodology for pH buffering. The potassium silicate is used for plant nutrient formulations (or at least it should be), so I had to add it at the beginning because of the pH spike from potassium silicate. I had to account for the pH spike when doing the math with Bru'n Water (and hence with UNH Alk Calc).

obviously I would use ro water and add all the different acids and silica, but not add any nutrients? as long as the ppm and ph is good?

I do not understand what you are asking here. Do you mean that you wish to use fertilizer(s) other than my nutrient formulations? If so, then yup, you would add the base (K2CO3) and acids, but you wouldn't have to add potassium silicate unless you wished to do so. If you do wish to use potassium silicate I suggest AgSil 16H from Custom Hydro Nutrients; you would add it after adding K2CO3, but before using Bru'n Water and before adding citric acid.

P.S. we give our plants silicon, not silica. It seems like a minor difference in semantics, but it's really two very different forms and plants cannot use silica as a nutrient.
