Hydrogen Peroxide to Counter High Res Temps?

you could add airstones. i started in an aeroponic system with no airstones(didnt think they were needed in aero since the roots are suspended above water but i was wrong) in about 80°F had nothing but problems with root rot. i added a few airstones and even in 80°F, it lessened the root rot a shit load, if i had to guess i'd say it lessened root rot by about 70%. still wasnt good enough though. i had to move my aeroponic system to a new place. temps are about 65-70°F and no signs of root rot whatsoever, and i dont even use H2O2. i am pretty new to hydro but this solved my problem. think i will eventually start adding H2O2 cause seems like everyone does it to keep things extra clean.
thanks, I am using an airstone attached to the air pump pipe.

in an earlier experiment with a bigger res (20-30gl?) at first I just put the airstones lying on the bottom of the res. then I had root rot. So I learned that it needs to be attached to the tube, otherwise it's no use at all (am i correct? can they help by just lying around?). I also learned about h2o2 then, and used that simultaneously so I don't know what it was, but the root rot problem was def solved and the plants responded well. This was with ambient temp of 19-22c, very comfortable. I'm now experimenting with a smaller res inside the grow box, where temp is currently 26.0 (79). not moved a lot.

damn thats big. mines just a small 2.5 gal lol. its made for cloning but im gonna make a custom top to veg and maybe flower. yeah you def need to have the airstone hooked up to the air pipe or it will do nothing at all. what these do is put oxygen in the water, just like a fish tank. roots actually need oxygen to survive. it is probably one of the most important things when growing in hydro. also very important in soil too. lol i remember when i was a teen i tried sticking a plant outdoors in a thick mucky swamp then wondered why it was slowly dying. sure that tall grass has evolved to survive in low oxygenated water like mucky swamps, but not weed. anyways, for my small system, in the res i have an air pump hooked to a large air stone. then another pump hooked to a T joint that airs 2 smaller air stones.

that high temp may still give you problems though. if you cant switch locations or find a way to cool it, maybe just switch to soil.

where is all of this induced air going to go? It doesn't matter how the air is put into the tank (air pump, h2o2, etc). Remember the warmer the water temp, the less oxygen it can hold. Fix the problems, not the symptoms.

you seem to be inadvertently answering the question I opened this debate for (this rarely happens :)). (actually someone else also gave a similar answer) - that no matter how much oxygen i put in the water, if it's too hot, it just won't contain it.

the question is, where is that boundary exactly and what is the best thing I can do about it - when I can't fix the problem (at least not fully) - how well can I battle the symptoms without having the (hypothetically grown in DWC) plants suffer.

i also remind everyone that I haven't done this yet - i just want to, but so far I'm not convinced that it's plausible.

If you can't add an ac or swamp cooler, move to a new place. It's really that simple. I see charts on the dissolved oxygen all the time on here. I'll see if I can't find one for ya. But what good would that do you? Go for it add the air to the tanks. See if that helps. What else can you do? Shit or get off the pot =) good luck man

lol what's simple about that?? you make it sound like you are serious :))

anyways there are other solutions like growing in soil or coco, which is what i AM doing at the moment.

anyways man, I will move, definitely, but only if you get me a green card :)

i so missed the post where you said your medium. Still not sure why AC is a problem. SOrry if I missed that too. Been way stoned lately. If money isn't that big of a problem go ahead and go for it in dwc or other hydroponic medium you want. Why are you wanting to switch mediums for?

no worries you trying to help is cool
the fundamental problem here is in deed that I am broke, no money for AC (which is very expensive both on the purchase and electricity).
I was wanting to move to dwc cuz i figured it's the best method, and well, I haven't had much luck with my previous soil grows. but that was actually on account of genetics.

my main problem right now is water actually. it don't rain here and my tap water sucks. saving up for an RO :)

for my next cycle when I hopefully have some money I wanna get an NFT system or something of that sort, I hear it's quite forgiving in terms of oxygen and stuff.

also, the humidifier I bought isn't doing much to the temp.

man thats a bum deal Im sitting here thinking of something for ya
provide as much info as you are willing to share
might help us with some more ideas
def try it if anything else sell off your gear
outside prolly not a good option but an option no less
Get involved with a local co op of some sorts

cool. the first (and only) entry in my journal covers most info:

This is sorta my third grow, the first was very successful but with crappy genes, the second was stopped early because good genes arrived.

Me: 30, male, in a small, hot country in the Middle East, that causes a lot of trouble compared to how small it is.

My setup: grow box 130cm (4'4") high X 110 (3'8") wide X 90 (3') long.
I use a 400w HPS in side a cooltube, ducted to a centrifugal fan (that is a little bit on the weak side but seems to be doing the job); some blue fluorescents where required, and a duct fan that removes air from the box into the room. the window is covered with two thin curtains.

the plan is for 10 pots, 6.5l (~2gl) each, 7 with 50-50 coco-perlite medium, 3 with good potting soil I know nothing about but has been growing plants pretty nicely. The box is tilted a bit and covered with mylar on the floor of it that drains everything to the sewer hole next to the box.

I have 10 hindu kush seedlings popping from their capsules at the moment.

we have summer most of the year, where temps are usually around 85, but can go up past the 100. also quite dry. indoors in winter (which is now) temp is about 65-75c in the room, 60-70c in the house with no heating. right now it's 85 in the box with a fan blowing there and only 3 pots inside.

I have noticed that the more soil I have in there the less hot it gets, probably due to better ventilation.

I also run a humidifier in the box.

so you were happy with the first grow
why not duplicate that grow with better genetics?
Research strains that are more prominent in your area. Lots of indicas for sure.
They might perform better for you.
Im hoping you are running your lights at night
although I have read issues caused by higher temps at night than at day
I forget if it had something to do with internodal spacing or hermis

once the problems begin with the hifg res temps they will feed off the extra oxygen provided from the H2o2, control the res temps.

do you think plants can tell if it's day or night outside their box?

well my first grow was actually a couple of bagseeds i threw in a pot in my balcony early june, never thought something would come out of them, let alone a grow up, that wasn't really planned :) and that 2 gallon pot was my best one, 10 germinated in it and 3 were there in the end gave me about 1.5 oz. the porch had about 4-5 hours of daily sunlight, and was diminishing rapidly as autumn set, and the sativas kept going and going till november... but i was very scared throughout the summer, my neighours saw everything, not the street, wasn't seen from there, but scary.

actually, now I have a huge porch with more than half a day of sunlight summer and winter. it has a part that can't be seen by almost any neighbor. but it's still too scary, especially now that my op has gone quite larger, I can't have visitors to my house knowing about it, or that neighbor.

should I discontinue the grow op, sell all the stuff and just grow a plant or two in the balcony? it's still dangerous. and only one harvest a year.

yes, night time grow should make a good difference, especially as I will be switching to 12/12 in the near future i hope. and maybe for next veg 250 MH which should be cooler than hps i think.

my area has only one prominent strain going (or quite similar varieties of it), it's a sativa that bedouins grow in the desert.

so i'm gonna go on with what I have now, no dwc, but coco. this will give me the best of all worlds. If it gets way too hot, I'll get money somehow and try to scrap up an AC somehow.

yes they can tell. During the night time air temps are lower and they will be happier. =)
don't try every bedouin trick, we don't want you feeding the plants coffee to stay cool next
good luck ackie

lol
they use camel piss
no actually they drink it (i've seen it!)

but I did find really cheap mini-ACs on our ebay! 2nd hand
sell for like 200 nis! that's 50$.
