If your reservoir is non-flammable, non-corrosive, can just pour some ethanol and light it on fire. That's how most instruments are sterilized in the lab. But my reservoirs are all some plastic, PE, PVC or rubber, and I use 35-42% H2O2. Kills most irritant microbes; algae growth has been the only real problem in my setups and H2O2 devours it. Plus, the decomposition of H2O2 releases oxygen in to the water.

H2O2 doesn't offer full sterility though. Any catalase-positive microbe is able to metabolize H2O2. Staphy's, salmonella, e.coli, enterics will survive.

Setting the res on fire huh. Well that's a first lol. There was the "burn gnats with a torch" lol

Not sure about size of the gnat but same poster swore Mountain Dew helped him grow some dank weed lol. Now what I found perplexing was the fact that the more dangerous method was to run a high current through the res :o. Tough choice lol.

wait what? mtn dew this thread?

and you mean between fightin gnat with a torch and electrolysis, that the latter is more dangerous?

yeah I'd live through either because I'm a pro operator at both, but I'd agree (with you) electrolysis is way simpler/easier/safer, hell I can run electrolysis without having to go to wal mart, and to run a good flamethrower that would take me at least 2 trips to casa de pot. and I probably got more than enough to both twice over without having to do either (trip).

I wouldn't be recommending that dosage if it had ill effects and a high fail rate ;-)

touche. fair enough, but in my defense, technically I didn't know you were actually recommending that, just thought it was a blazee "this is what I do" answer

I still really really want to know the actual math, not just a passed on formula the likes of what we have and is posted here, but rather an answer from somebody that actually knows how to calculate it from knowledge, not plug ins.

I think my stock is way hotter than yours and the math supports that guess I think.

I just need to find a happy medium to kill what I want dead and let live what I want living.

Re the Mountain Dew, no not this thread lol. I think both methods, fire and electricity are foolish lol. Go back and have a look at Jiji's older stuff, she posted some really good info on running sterile and monitoring ;).

I've been through this thread completely, haven't seen any of her other stuff.

and, NO NO NO, I don't mean anywhere near my babies, I mean out in the yard makin explosives and shit. bonfires, tater cannons, KClO3, etc. but still foolish to attempt, dangerous no matter how safe you try to be.

guy I learned how to make nitrogen triiodide from only had about two fingers and safe or not, that's the epitome of dangerous. that was kinda my point, as you said prior.

anyway, this is the only sterile/monitoring thread I've come across but I searched for this thread by name looking for this math/chlorine

Mmm bleach bud! Whats it taste like? Nothing? Jizz?

Don't worried silly hydro airbud growers, even some soil growers are stupid too and grow crappy peroxide tasting bud.

Let's say you grow a pineapple strain. How can you get ethyl butrate without clausseniito eat the butric acid? Oh that's right, if you grow pineapple strains you just use ADDITIVES to fool yourself! Just hope you bought enough Derpinator sugar water products so the plant soaks it all up! All that sugar water will make up for growing in a swimming pool! Hahaha how can anyone smoke that shit? Only because they are delusional! Fake hydro weed grown and sold to delusional placebo people. Cant even get a buzz proper with that jizzwater airbud!

Growing that fake bud with garbage out of the back of high times! You don't even know real weed is a completely different thing than that hydroponic wannabe stuff you've convinced yourself into smoking.

Lettuce in the shape of weed! Hahaha Maybe some of you will wake up and grow real weed some day, when you accidentally drop a seed in your yard and its the best shit you ever smoked!

I sure wish you would call out stinkbud by name

https://www.rollitup.org/t/harvest-a-pound-every-three-weeks.116859/page-1

even though he has gone back to soil, argue that shit with him and I know who my money is on.

I've grown it all young man, and if it can be grown, then fuckin grow it and if you wanna have an attitude and put other people down for doing something that is ultimately good, then find another thread in which to antagonize people in search of knowledge

The issue with chlorine is it may not dissipate before adding more. Pretty sure she has formula in one of her threads,

it's in this thread, but I don't want a formula, I want to understand the concept to where I can do the math all on my own and make it do anything I want it to do, 1ppm, 0.1ppm, 10,000ppm, etc etc etc

wow somebody sure got butthurt, always nice when one of the soil elitist's socks gets away from the hamper and smells up a good thread. For me personally, all of my problems ceased after i started adding beneficial organisms, so ill never go back, but there's always more than one way to catch a frog

Can you not use a meter or some kind of test strips to measure?

this thread talks about orp and its values but I don't have one yet and a good one is pricier than I can afford atm. my point is I want to be able to make a stock concentrate of known strength and then be able to measure out a known amount and add it to the res easily, like a shot glass, 30mL, rather than weigh out 0.15g of dry powder each and every bucket or every time I do a treatment.

I need to streamline the process. Plus I am ocd about these things, I cannot, repeat CANNOT just let things go, I have to learn and know and understand.

"Get busy learnin, or get busy dyin"

Or keep it simple and run hydroguard, if overdose no harm to plants, and it really did seem to help root growth, I found using bleach/chlorine it was always a guessing game.

I did just get some but haven't made the transition yet, as you know they are incompatible. Or rather, the chlorine will kill the hydroguard. I have a big res I fill my buckets from and as soon as I empty that and am ready for a refill on the big one, I will try the HG. It already has had a little chlorine in it and prior a little h2o2 which will also kill HG iirc.

I still want to know the math behind that though, you just ain't gonna talk me outta that!! Even if I don't ever use it again, I just have to wrap my noodle around the concept, or the exact calculation anyway, I get the concept, just not the calculation.

Wonder when jiji might come back??? I know there's a hundred others on this forum that can help me understand the math, trouble is finding them.

Not trying to sway you at all, just a suggestion lol. I can't get it here as it's not been approved, haven't looked in a bit though. I don't run anything at all except chiller and all good so far :). I'm actually switching to a non flooded root zone setup in the fall. Need a chiller lol.
