This is great thanks Spurr. I too am a jean us I have a triple digit IQ as well. It's zero zero nine.
This is a lot to take in lol I have homework to do.
There's a gold star waiting for you once you get an A!
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
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.
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.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'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).
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 silate unless you wished to do so. If you do wish to use potasasium sialte 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.
I knew potassium silicate wasn't used for ph buffer. We are talking about pro-tekt right? sorry I didn't realize silica and silicate wasn't the same
... 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 was just talking about giving plain water in sunshine mix.. Would I still add protekt and citric acid.
This is how I have been mixing, I know I can do better but what do you think about this until i get a combo meter:
50/50 ro/tap water
ascorbic acid
2.5ml protekt
2.5ml of lemon juice from the produce section of a grocery store
4.5 ml of ph down
8ml of gh micro
14ml of gh bloom
that makes me ph between 5.5 and 6
I am just trying to find a decent method until i can afford better stuff to work with like a tds meter.
How do you think your new PH adjusted water would work with your 5/5/5/5 recipe no need for pro tek now of course.
Also when using the preph water with stuff like pond enyzes, sweet, flora nector and so on. any guesstamated effects?
DAP is higher purity and has less contamination than MAP, there are industry standards for DAP and not so for MAP. That is why I choose DAP and not MAP.oh yeah why DAP vs MAP? dap is more solubable but cannot find online haifa map is easy to get at landscape supply
nevermind 11-62 vs 18-46 hard to get 25%nh4 and keep p low
Hey there Spurr, just a few questions , i see your new formulation incorporates quite a bit more Si (80-100) ppm than the previous 28.85ppm in your previous formulation.
Can you please elaborate a bit more on why you chose these specific amounts ( why not less or more ) of each element especially P, since i see it is now up from previous 52ppm to 87ppm.
I understand you have separate veg and flower formulas now but i thought you were researching that less P is necessary (-+50ppm). So yeah please explain more about this please ! really interested
[ please also explain the reasoning behind the higher N (NH4+) to NO3 ration ... ]
