Bleach in DWC

Hello, I have resorted to adding 8 drops per gallon of bleach to my 5 gallon bubble bucket after battling the slime. After researching, it seems to have no ill effect to the plant. Just curious if anyone else has used bleach and if so at what strength? How was your results?

I have tried H2O2 30ml/gal at 17.5% NO HELP

I have tried Sub B, voodoo juice, and orca NO HELP

I have clean setup with optimal res temps NO HELP

None of these have done a thing an so I have decided to run a sterile solution. Please don't waste your time advising me to try any of these techniques I have already mentioned or to brew a tea. My question is strictly about the use of bleach in a sterile environment, nothing else. Thank you all for your time and advice.

dutchmaster zone. it's chlorine and copper. cheap and easy to use (not quite as cheap as regular bleach). i use at 2mL/gallon.

You ever figured up how much chlorine your are adding at that rate?

nope. it's enough to never get root rot. you could look at the label online and maybe figure it out.

Yeah, I just emailed them. I just am trying to validate the use of chlorine as being a safe tool to us in hydroponics. So many jump on the teas, bennies, and h202 bandwagon that if you even attempt to mention using bleach they rip your guts out. I however see no problem using it as a cheap and effective preventive against pathogens. And the more I think about it, it seems the plant will have that much more oxygen without the bennies there to consume it. Added some this morning and have been monitoring, so far so good.

been using it for 4 years now in hydro.

Do you use start to finish?

if you are on muni water, you drink bleach everyday

of course!

I use deep well water from a spigot out at my moms house. Best water I found so far, my town water is 650ppm, barley potable, hers however is in the low 200's. I may have to get me some of that zone. Looks cheap enough and seems like it would last a while.

i mix RO and well water. no need for cal/mg that way.

a liter was like 13 bucks on ebay. i use 20mL a week. so yeah, it lasts a long time.

Thanks for the info. I will have to give it a shot.

hey budley, you surprised we haven't seen a post about oxygen concentrators and 180% oxygen saturation from our buddy in Minnesota?

Well, been bubbling it for about ten hours now and the water is kinda cloudy with little pieces of root floating around. U think that is just dead material? Should I change results again tomorrow with fresh?

i would get the roots out for sure. maybe just like a kitchen strainer if the pieces are big enough? if not, dump and change would not hurt at all.

Probably just change tomorrow morning. I'm guessing with each change the dead materials and cloudiness will abate?

i'm guessing you maybe had a bit of root rot that the bleach killed and the dead roots are sloughing off

LOL, now that you mention it lol. Hoping aero gets his free one in the mail soon .

I fought rot for my entire first time and at the end began using pool shock to use in the root zone. The last 2 weeks i cleared almost 80% of it up (I used bennies and h202 with no success) . Second run and i havnt seen a single sign of any root problems and the plants are nearly double what they were my first run. All you need is like a gram a gallon and then like 21ml every 3 days per 5 gal. Also a huge plus is i took a clone (first time ever) and i couldnt get it to root no matter what i did, used pool shock and bam 100% success rate and 3/3 cloned! If you do clone tho and use a spray bottle make sure not to use any shock in it
