i am currently experiencing beginning to middle stages of root rot, as it is my first time growing soiless and going hydro i accounted and prepared for many issues id probably end up facing, one i have not been able to battle successfully is rot and the rising temps of my solution i can effectivly remove and clear all rot and within a week its back again has me dumping a lot more than id like in turn wastin more money than i like. heres my idea after reading several threads on here about how to control temps i noticed a lot of suggestions are pricey or precise if you miss even one step you could inturn actually harm your plants further, after a week of planning and brainstorming ways to avoid spending boatloads of money i came up with an idea im about to finish and test for the first time here it is let me know what you think and your personal opinions as im not an experienced hydro grower ive only ever grown clones in soil.
things im going to need: water cooler (approx 6x20x10)
bagged ice (frozen bottles or ice chunks will work)
tubing of your choice (ill be using cheap blue aquarium tubing)
a drill
air pump
airstones.
now i have yet to test this im currently setting up while i write this but my idea is to fill my insulated cooler with any kind of water so long as its clean, and lots and lots of ice, i will attatch the pump to the lid of my cooler in hopes of cooling it even if only minimally, the real goal and hope is to push my tubing through drilled and grommeted holes in the side of the cooler and have my tubing run through the icey water in an attempt of cooling the hot air my pump is pushing through my tubing at the same time this will block my lights from reaching majority of my tubing so there shouldny be any additional heat through the airs travel also allowing me (hopefully) to by cheaper tubing and save some money. now the reason i wish to drill my pump directly to the lid of my cooler is the surface should be a lot cooler with all that ice inside it wont perfectly regulate my pumps temp but it will help keep it to a more controllable level as im using a few 35watt pumps they heat up rather quickly. the goal is to reduce my maintence right now im using water bottles ive frozen directly in my dwc like many who do not wish to spend the money on a chiller suggest,the problem ive found is the bottles only last about 2-4 hours until melted and regulated to same temp of everything else im hoping with a proper insulated cooler to reduce this to maybe a once or twice day dump and refresh as it will be located just outside of my tent i also believe it shouldnt cause many issues with my humidity either as it would locsted in the tent.
sorry in advance if my post seems to ramble or just uninteresting in general ive followed many threads and people who have helped me out on here but never actually signed up and posted anything myself so im not completely in the social loop just yet.

that costs about half of my entire grow setup for 2 plants im really trying to avoid spending ridiculous amounts of money on a chiller its something im looking into for future higher quanitity crops but for 2 plants im only looking at one as a last resort for me but thank you

"
2. Water temperatures

Depending on the type of plant growing, temperatures need to be managed in the DWC. A healthy range is 62-68°F (17-20°C). Above 72°F (21°C) and dissolved oxygen (DO) dips too low. Below 60°F (16°C) and plants tend to slow their metabolism as they "think" the season is changing. Depending on what you want the outcome to be, this could be both useful or disastrous."

Not an expert but I have been there.

Hydroguard will help with the Rot as the bacteria outcompetes the cause but if your temps are high Harley’s right it won’t turn out good man. You may want to just move to soil unless you have the time to try your experiment and don’t mind if it doesn’t work. Good luck either way hope your plan is a success.

Yeah bennies is your best hope there’s a few out there I’m currently mixing and matching. First grow using bennies. It’s way easier then keeping a sterile grow. I also have 1/10 hp water cooler keep it between 68-70.

If your heart is set on DWC, your going to have to control your temperature. Save money like your life depends on and buy that chiller!
 
my original post was described very vaguelly what ive actually done is took a water cooler a peice of cardboard and some aluminum, i cut holes in the cardboard big enough to slide my buckets into and i cover the cardboard with aluminum foil for reflection, i fit it to the top of my cooler (as the original lid had a dip/groove to it that just wouldnt allow two buckets) and bam i now have a housing system for my single dwc buckets which i fill with ice once a day and the insulated walls of the cooler keep it nice and cool all day, i have lowered my water temps from 70-75F to 65-69F. i have also drilled a few small holes in the side to run my tubing through the icey water as my pump runs hot this gives the air a slight cooling before entering my buckets, i now have new white silky roots exploding and have pruned majority of my dead/rotted roots and for those talking about bennies, i run voodoo juice and tarantula they did not help rid my rott but did allow my plant to overpower it and continue to grow new and thicker roots i just ordered some Z9 (canada) in hopes of being more prepared to combat this problem in the future, appreciate all your inputs as a new member especially, its nice to not feel treated stupidly for common mistakes and misjudgements
 
just fill it with a bag or two of ice maybe a cheap tape job to keep the cardboard flat to the top unfortunatly i went to switch out my buckets and realized i dont have enough new tubing to fully attatch it again, thankfully i know im forgetful and did not dump the buckets in use so im good to go til tomorrow when i hit up the store, will update when everythings transferred and running, for now lol how you guys think it will work? keep in mind my temps arent way out there just a little out there lingering between 70-75F im just trying bring that to about 65 and keep it consistent. PS the ducttape bucket is not the one im using just the one i used to cut the cardboard to size and test all my dimensions make sure it all fits, im aware its far from lightproof
