I’d go with phosphoric acid bro… it will hold the pH much longer

Hey!
Speaking of acid, I've heard sulferic acid is good to use in flowering instead of phosphoric. Is this accurate?
I have some sulferic acid otw, and was wondering last night if it's ok to use this to lower pH after silicate or to still use phosphoric acid for that and sulferic acid for normal lowering

Yeah it can be. I wouldn’t say one is a must over the other. It can make a small difference in nutrient ratios where in flower P demand is lower and sulphur is a bit higher.

Both work well for Ph adjustment and you can even use some of one and some the other

@Observer I like the high pressure setup, should be a few steps up over low pressure for sure.

I have a little insight into this:

Mycos have worked for me in hydro, in DWC, aero, and RDWC. The catch, I had to start with "clean" water to be able to go live without any baddies growing and without killing the good ones. The easiest way for me is to just start with RODI water, no dechlorination needed.

I'd like to think that's why I have the biggest and healthiest roots and plants I've ever had this go.

I think this was a week or two before switching to flower. I'm scared to even look how big they are now. This is all live with beneficial bacteria, tricha, and mycrohorzie.
Gets fuzzy and all that good shit lol

I’ll take meatballs and parmigiana with mine please.

Looks good, testing pending.

 

[Zen_seeker]

To me, so far, right now, this is the most complicated part.

This irrigation needs to come on as soon/right after the water is evaporating off the root system, just before the roots "dry"


Imo, in my thoughts, this is the most optimal timing.

I just gotta Observe and Map that Pattern, correlate to the Timer/Cycles.

No sensor you can make/buy to put in with the root zone?

 

[Zen_seeker]

Sauce is thick tonight.

This is as close as I budgetly can get to Moe's giga efficient systems.

You find it?

 

[Zen_seeker]

Hehe

Sitting here with it, Observing.

Just amended the distilled water to the "correct" variable ranges.

Grafting weed to bamboo next?

Glad to have you confirm this.
I just bought my second bottle of pH down and made sure to get phosphoric over citric.

I think it was the cheaper choice also.

 

[Observer]

Yea citric acid is just weaker

But supposedly citric acid acts as a chelator too, so that sounds good

and it was cheaper for me to buy from Walmart.

I still need phosphoric acid to make MSA with pot sillicate....and then I need KoH or another base to create a pH buffer for my solution with phosphoric acid.


I wanted to get a bottle of 85% phosphoric acid but more than what I wanted to spend atm.

No just weaker it reacts with bicarbonate and off gasses very quickly so the effectiveness is not good. Its only good for mixing nutrients to keep them in a ph range where they don’t precipitate out. Say for like soil where once you pour the nutrients in the soil will buffer the ph.

Definitely not good for hydro

Ahhhhhhhh


I have to keep checking it

Not very stable at all



Thanks aqua

It has both phosphoric and citric acid. Cleans soft pots nicely in 5g pale.

@Aqua Man this is what I was wondering about, will another acid react the same with P. Silicate, like sulferic acid? Do I have to use phosphoric acid when lowering the ph from p. silicate before adding nutes, or any acid will work?

I believe I got the bulk pure acid idea from you aqua, def way more cost effective. and then dilute to your liking.

just came in today:



and then pure phosphoric acid (I think this will last me a lifetime, only used a few mL so far to make a huge bottle of diluted mix, that i've barely used)

There are products that contain citric, phosphorus and sulphuric acod.

Any acid will work to lower ph and a combination of sulphuric and phosphoric would be great

Always add acid to water when its concentrated… never add water to acid.

Dilute it atleast 10x before adding to res

Only have baking soda to bring it up .1

Needs another filter, you think?

I could put a little sponge or something in that plastic filter it came with, it has 2 steel balls for weight

niiiiiice!!

niiiiiice!!

At 15 minutes, 5s on

i got up to 25 minutes off last night and that seemed 2 long though. (Too dry)

And I think 15 minutes is too frequent...
(Too wet)

Might just go up to 20 and let it sit there and observe for a bit before adjusting anymore.

I think the cubes are 2 wet.

Only if anything is getting plugged brother

Ok cool

Thx

Only at 50ppm right now.

Trying to keep the salts precise for what the plant needs to help prevent buildup and clogging

 

[ninjadip]

you thinking of filling up the cup with something? guess it's too late to put something under the cubes.
maybe that could help wick the water from the cube

I got some pure coco, I could maybe wet and stuff in the cup.

But trying to keep things as clean as possible and minimal media for anything negative to grow

I do wanna try it with one of the netcups, oh and I'll have to no more cubes lol

 

[Observer]

Need to get all the other holes drilled so I have more plants to watch lol
