Bleach instead of H2o2

Ok then, I would make an effort to save them as you can see if you look at my root rot thread, but I'm kind of stubborn lol. I also shut my indoor down in another 2-3 weeks due to heat. And it's cheaper outside.

At those temps it's only a matter of time before it hits them all IMO. It's a pain but what about ice bottles and insulation
Im at 23 celcius right now and Will keep it like that i think i woul throw some javel in m'y réservoir and wait for a week if it help i Will keep them if not i have to kill those ladys

Still high IMO but if there's nothing you can do then that's that. Again you may be able to save them by insulating the buckets and Res, also try hydroguard if you can get a small trial container (possibly email them) or buy it to see what you think. Again I'm stubborn but came real close to quitting. I now have one of my best runs ever, albeit second generation :).

Google Live or Sterile? Elevated my grow 100%!! If you can control your water temps and keep ideal environmental temps this Will help you! Seriously almost made a night and day difference for me. Google is a hell of a drug!LOL

Took a bit for me to get it. But yup environment is key to a good grow as opposed to just a grow :).

So bleach it's à no for me !!!
150ml... that's a LOT! You should be aiming for 1-4 ppm of chlorine.

Have a look at this bleach calculator:

https://www.publichealthontario.ca/en/ServicesAndTools/Tools/Pages/Dilution-Calculator.aspx

Typical bleach is like 5.25%. You should have put 2-8ml in TOTAL volume of 100L for 1-4ppm... not 150ml of bleach!!! You have like 80ppm bleach solution circulating. smh

Of course bleach is a no when you're putting insane concentrations into your nutrient solution. Chlorine gasses off at about 1ppm per day. It'll take 3 months for the bleach to dissipate from your system unless you drain it. If you want to save the plants you need to empty the system now. Run through plain water for 24 hours and then start with like 200ppm nute solution.

Edit: I was reading last night that upto 100ppm is ideal for immediate sterilisation of surfaces. Over 100ppm and the bleach starts to react with metals. 25ppm is recommended for ultra high purity water systems. 80ppm through your nutrient solution is crazy!

True i did burn them it was bubling. i Just order some hydroguard and Will buy some sweet for my next batch .i was thinking can i feed the bacteria with molases or it's better sweet in a rdwc?

Don't feed the bacteria in your system, just replace the bacteria. I Replace the Rez water every 7 days and add the beneficials. I add 100 ml hydroguard to 100 litre Res.

I fought on here about using bleach and was ran out of the village by a torch wielding crowd lol. But......I am almost to the point of grabbing a torch lol. To much guessing, wondering about the amount of off gassing. And no real benefit that I can see for the roots other than disinfecting. As for H2O2, well it did work I guess, but not great, kept it at bay. The one thing is cost, I hear that all the time, bleach is cheap. Really when your talking a couple of thousand worth of product does it matter if you save $20, actually food grade H2O2 35% is getting to be hugely expensive and hard to get here, it's almost like your buying bomb materials. I started using hydroguard last fall due to a huge root rot problem. I did hook up a chiller as well but I have had nothing but a huge white root mat. It is my opinion that if you want to kill it in hydro and maximize the grow you need a chiller first, then you choose what's, if anything is needed. I myself have stopped using any sterilizing products. I'll try to get a pic up right after harvest which is in a week or two I hope.

I don't really understand the logic behind fighting something that's clearly working out wonderfully for many people and is widely avaliable for everybody. The fact that it's being used safely on a industrial agricultural scale makes me wonder if you sell products or something? I really don't know. But for me the logic doesn't add upp. I've seen amazing result in both clear rez system and alive ones, that's not the point. For me it comes down to the amount of time I spend on a project, safety and stabililty.

PH stabilitly in hydroponics is key and I have personally never been able to keep as stable PH with alive rez as I now do with sterile system. Much lesser jobb and guessing game and as a byproduct also higher yields. I've been using sterile system for about 2 years now.

Follow directions and always do your own research, no reason to sit on the high horse... ;)

The only time I get huge swings is when there are issues with the root mass, I didnt find any difference between live and sterile to be honest as long as the roots are healthy my PH will slowly rise which I like

Need some input. I'm dealing with fungus gnats. Soil has zero nutrients or mycos (Aged bark, peat moss, coconut coir, pumice, perlite, lime, dolomite, gypsum, and yucca) + 50% perlite, I'm full synthetic. I first used H202 seemed to help, then I got bti bacteria (mosquito bits), and now I'm considering 4ppm bleach through the soil.

Will bleach "kill" the "inactive bacteria" bti and thus be counter-productive, or does "inactive" mean the bacteria is already dead?

Will bleach kill fungus and gnat larvae?

I haven't had them since switching to hydro, it was one reason I made the jump actually. I'm surprised the mosquito stuff didn't work. Not sure if I'd add bleach to soil as yes it will kill everything. Less watering, sharp sand, sticky tape, I tried everything and then went to hydro lol. They didn't seem to do any harm but just hated having them in my buds when I harvested.
