Hey guys got a small girl in my cab from nirvana strain is blackjack. Everything has been going good. But it has been getting hot in my room. I know my Rez temps are high. Starting to notice alot of brown clinging roots. I have read a decent amount of different info from alot of different ppl. The thing I am hearing the most is when using 3% h202 you should use 10ml of h202 to each gallon of water in your Rez. Has any one done this before and if you have could you fill me in on the dilution ratio. And how often I should re apply h202. Thanks for any help!! Rep to all conrtibuters.

If you have algea on your roots, then you have to have light hitting your roots. Algae can not grow with out light. Make sure the roots are not getting hit by any Light and the algae will die. The only thing the algae does is eats some of the nutrients you are feeding your plants, so fixing the problem will turn your troubles around quickly.

yes the info you need will be in the al b. fuct stickys in the hydrosection... 3% is no good. you need 29% or stonger. 3-10 mls a gallon depending on what your doing with it. 3% has a stabilizer added that interfers with the chemicals or something?? Al is the man all the information is in there. al b. fact thread

Plain and simple, make sure there's no light leak inside res, and then head to walmart and go to the fish section, look for a product called algea eater, best stuff I've ever used controling and avoiding algea problems,, I always use algea eater jusyt to play it safe.

If you are going to be useing H2O2, remember it also reacts with certain types of nutrients and additives. So make sure to do a lot of research before just dumping it into your rez.

What kind of system are you running? If it is Algae it will be green not brown. At least the Algae I know of. When I used to grow in a Hydro System I had algae growing. I just made sure that no light was getting to where the algae was growing and it all died off.

Also, you said you rez temps were high. What are they?

Al would say organics and hydro are pointless, but none the less good info ldb.. fix the light leak its the cause of your algea.. barley staw filters or uv sanitzers also will kill the algae.

Hey guys thanks For all the fast replies. Just to let you know I have no light getting into the rez. I am just doing a DWC bubbleponixs setup. My problem is my Rez is getting to hot. Algea can thrive any where that is low on oxygen. When your Rez temps get higher oxygen depletes. There is no light getting in for sure tho unless light can go through hydroton all the sudden. It is just so fucking hot where I live right now. Sooo will the 3% help me. The plant is only about 2 weeks old maybe a lil older. I will do just straight water while I am using any h202 that way I am carefull not to block out anythig my plnt needs. And again if any one has a ratio that would be great thanks. O and where do I find ALS facts?

no 3% does nothing for hydroponics.. maybe freeze ice bottles and pitch them in the res.. keep one in res and one in freezer and alternate them once a day???

I guess I could do that. But that was going to be my last resort. If 35% peroxide is not available where I am what would you recommend using? Thanks for all your help. What I might end up doing is going soil for all of my summer indoor grows. And go Hydro in all of my winter grows. I have been growing for about a year now. This is just the first time it has gotten this hot. Even if I use the frozen bottles this isnt going to kill the algae that is already living in there will it? Thanks for all you help to every one!!! rep to all

Dont take this post the wrong way because I am not trying to come off as a dick. But there are 181pages of ALS thread there. I cant sit there and read them all. Do you have any idea what page it could be close to cause I will be happy to read 20 pages but there is no way I could go through 181 with out dying.

Greetings and hallucinations. Got a bit of a break from the usual grind, so I thought I'd check in.

Have taken a bit of a stroll around the hydro forum. While there's some brilliant people doing brilliant things, a few folks have been drinking FarkingClueless™ by the megalitre.

While I DO have a little bit of free time at this moment, I don't have time to visit every thread and comment. I'll proffer these general observations, though:

* Laundry bleach (sodium hypochlorite, NaOCl) in hydroponics: Just Don't Do It. PLEASE. Use H2O2, 50% grade at 1ml/L of nute soln, applied every 3-4 days. Controls all pathogens and oxygenates roots when H2O2 breaks down. NaOCl is toxic to cannabis plants, as are its breakdown components, inclusive of NaCl (sodium chloride eg table salt).

* Molasses/sugar in hydroponics: LAST TIME- plants can't eat complex carbohydrates, but many pathogens CAN. You're growing cannabis in your hydroponic system- not anything else.

* Chlorinated municipal tap water is fine for hydroponics. Fancy water filtration systems are completely unnecessary. Chlorine, in the amounts applied by muni water treatment plants, is completely harmless to plants and people. High TDS readings from 'hard' water are caused primarily by dissolved minerals like Ca and Mg, both of which are necessary micronutrients. Any water suitable for drinking is excellent for hydroponics. The only reason one would ever have to ever use expensive RO or filtration systems is if one is sourcing water from a local bore/well, where water may contain high levels of salinity or sulfur. In 25 years of growing dope, I've never once seen tapwater from a municipal system cause problems in a hydroponic grow op.

* Organic hydroponics: Is complete nonsense. The 'organic' buzzword is overused and largely misunderstood by the general public. 'Organic' doesn't mean 'good' or 'better.' It means that the material in question is sourced from a biological system. Organic nutrients are, in actual fact, mostly shit. Compost and manures themselves are not assimilable by plants; it's the breakdown components, N, P & K, which plants eat. There's no difference between the N, P & K obtained via organic matter breaking down and that obtained from "chemical" aka inorganic fertilisers. However, inorganic nutes allow you to precisely and CONSISTENTLY control the amount of N, P & K presented to the plants. With 'organic' nutes, you never really know what the precise amounts and ratios of N, P & K your plants will actually get. Moreover, inorganic nutes are not affected by the use of H2O2 in hydroponic nute solns. Inorganic based hydro systems are clean, tanks are clear and such systems are much easier to maintain, especially for the newbish. Now, before some holy organic evangelist upbraids me for not knowing what I'm talking about, know ye this: my veg patch out back is run on organic principles; my cannabis plant waste, lawn clips and kitchen veg cuttings are composted and incorporated into the garden soil after spending about a year breaking down in the compost bins. It works pretty well- outdoors, where I don't give a damn how many bugs & microbes are hanging about. In my indoor hydroponic grow-op, I want to have only ONE living organism: cannabis plants.

So, wut up, dawg? .. this is the forward​

ThanksYou're not hijacking at all. I'm here for a few days specifically to answer queries like this, but thanks for your politeness.


It's really hard to overuse H2O2. It's so hard to overuse it that I can't really tell you what the symptoms would be. I've never deiberately exposed a plant to straight 50% grade H2O2, but sometime when I'm thinking of it and have some excess rooted clones which would normally go to compost, I'll try it and get back to you.

Plants will happily tolerate 10x the dose I usually suggest (1ml/L of 50% grade). A system which has a big pathogen load can be hit with 10ml/L of the 50% grade as a once-off shock treatment, but a system which has been dosed regularly, every 3-4 days at 1ml/L from day 1 shouldn't have a big load.

50% grade is usually available from hydro shops but failing that, check foodservice or general chemical supply houses. I persuaded my local hydro shop to buy in a pallet of 25L jugs of 50% grade from a local chemical house. I pay $AUD90 for 25L 'carboy' jugs.

If all you can get is 29%, use 1.75ml/L or 6.7ml/gallon. Make friends with the metric system. It's an awful lot easier to use than imperial figures.

This was very helpful thanks you much I would give you more rep if I could. I would Thanks AL to if I could but i guess he is gone!

Hey guys checked out the girl yesterday. The longer roots are still brown of course. Cause I haven't got any peroxide yet. But I did notice a shit ton of new growth all very fuzzy and healthy. I am going to be using frozen water bottles cause I guess that is all I can do at the moment. Anu ways thanks again for all your help. I am pretty sure this bad biotch is going to pull through juat fine. STAY HIGH!!!!

Is there anyway to put that rez in some place just outside of your room. Somewhere cooler and not in direct light from you grow lights?

forget all that H202 stuff mane.
make sure your res is light proof
then buy another HO airpump, and another water pump - you're looking at maybe 100 bucks. probably like 50.
if the water has too much 02 in it algae cant grow, POW!
if the water flow is too rapid algae cant grow, BLAM!
and your plants will have double or triple the amount of DO in the water
ive grown in water temps over 80 deg, if they make it through the 1st 3 weeks, then its all gravy
**if you cant buy a chiller then this is the best option (IMO). ive tried H202 before and it set my plants back longer than it was worth.
unless the plants look like they are really suffering then they usually are OK even with some browning on the roots.. they will just continue to produce more root fibers to account for those that they are loosing due to high temps or algae growth. does this perhaps slow the growth rate of your plants? idk.. maybe a little.. but unless you have the dosage perfect on that H202 it can really fuk your shit up.
