They use sulfuric acid for batteries... I think youbwere joking but honestly ppl need to stop looking at the other uses for stuff and saying it's bad because it's used in this or that. Urea is a good source of nitrogen for soil grows... not so much hydro that often lack the bacteria to break it down.If I am not mistaken, urea is a major component of DEF fluid for use in modern diesel exhaust systems. They have to regenerate something in the exhaust periodically to keep them running clean. So maybe you should confine its use to the diesel strains. LOL!
Case and point... arsenic is good for the body no?
I'm betting almost 100% of ppl say it's bad for you. Well surprise it's absolutely needed for the body and plays an important role. But in high amounts definitely not good for us.
Ppl have this need to think that if it's bad in one application it's bad period. Idk why in this day and age everything is black or white to ppl and they have lost the ability to use perspective to see that almost no answer is black or white.... the truth lies in the grey.
No need to shut up bro... you brought up a good talking point is all. I try to take them to make points and pass along information. These convos don't start without a beggining and are very beneficial to have I wasn't directly referring you in particular and wasn't sure if you were joking. Just thought it was a good opportunity to have this conversation.Yes, I was joking. Didn’t mean to miss lead anybody. Used big time in fertilizer. Seems to be a very versatile compound used in many different industrial and agricultural Applications. I didn’t mean to infer that there’s anything wrong with it. Maybe just a miss guided FYI. I’ll shut up.
Ok so what actual products do you suggest to adjust PH in hydro/DWC?Sulfuric and phosphoric will give you the most stability if you have a proper buffer (alkalinity)
Ph up can be many things. Most common is potassium bicarbonate. Silicate, hydroxides and carbonates also work.
No need to bubble what I'd like to know is the ppm or even better the local water report. Just so I can see if it has an adequate buffer and what the makeup is that may need supplemented to jeep your ratios in a good place.Unfortunately, I have to use tap water for the first rip or two, the person who's house we're using doesn't want to waste water with RO.
I will be doing a live DWC rez.
I will let the tap water bubble for a couple days to get rid of chlorine before using it for the weekly rez change
So it's likely your chlorine or more likely chloramine is around 1 ppm. This is almost negligible. Chlorine is actually a micronutrient.
Yeah just the pharmacy stuff. Potassium silicate can be used as up and yes all dry.Ok thanks for all of that info, you've been a great help in many threads!
So for chloramine, just get some pure vitamin C powder offline or from the drugstore?
Is there a PH Up product you can suggest that is just potassium bicarbonate? I can get this in a dry powder right?
For PH Down, I've found this phosphoric acid 85%:
But is phosphoric acid 85% available in a dry form?
Is this stuff easy to dose? I assume just a couple of drops per gallon/5 gallons will be enough?
I do not live by the coast, but the great lakes.
My nutrient plan for DWC is:
Grow Genius Mono-silicic acid
Cutting Edge Solutions Sour Dee
Powdered Fulvic Acid
Amino Acid powder (at the proper time)
B-vitamins (at the proper time)
Enzyme product - I haven't narrowed this one down yet as I'm still doing research. I know Hygrozyme is a good product, but others have also been suggested.
Kelpak during veg
dry kelp during flower
batswel during flower
Bloom Booster (probably Jacks)
So just use something like GH Armor Si for my PH Up?Yeah just the pharmacy stuff. Potassium silicate can be used as up and yes all dry.
Ph down is almost always liquid unless citric acid.
That seems like an awful lot of products I would have a good read here bro. The more you add the more problems.
I love fertilizer. I work with big grows down to friends that have a single 400w light. I recommend the same thing to each and every one of them. It is used start to finish, so there's no following confusing feed schedules. A buddy of mine started calling this "The Recipe" because it is cheap...www.thcfarmer.com
Yeah you can use potassium bicarbonate and only will need a tiny amount if any depending on alkalinity of tap. It's more than like good.So just use something like GH Armor Si for my PH Up?
I thought silica dropped PH hard, that's why you are supposed to add it first?
Would using Potassium Silicate as my PH up be a problem with using my Grow Genius Mono-silicic acid?
Doesn't potassium silicate give calcium lockout if used too much?
I know it seems like a lot, and may drop something like B vitamins, but a lot of those will only be used at certain times.
I've been reading that ballin on a budget thread and has been great info. But there are still a few additives I'm really wanting to use.
Why is GH PH Down so popular for hydro, but because of the citric acid isn't the best choice? You would think they would drop that out of the ingredients?
