DWC Water Temp

[Baker783]

So, i recently switched my whole setup from soil to dwc. Nothing major just got some 6 in net pot lids for 5 gal buckets, picked up gh flora trio, and air pump etc.. Biggest concern im having right now is i keep seeing i need to keep my water temp below 68 to avoid algae,root rot etc. Ive done all i can and ive managed to lower my ambient temp to an average of 72 which causes my water tem to fluctuate between about 69-73 if all else fails i may just use frozen bottles as i simply dont have the money for a chiller. If anyone has tips on possibly lowering the ambient temperature in my tent by about 4 degrees,im all ears. Thanks in advance!

There's stuff to add to your res when you can't keep temps down.
Hydroguard is one the products I do believe, and some use hydrogen peroxide.

Good luck

Thanks m8, i dont actually think its as big of an issue as i think it is, its jusst my first run with hydroponics at all and i prefer to be over-prepared.

Sure can be when you get root rot halfway through flower.

Good
You can get 30% H2O2 at a Hair Dresser supply place.

And, I think that air in the roots is like light on the leaves, it's kinda hard to have too much.
When you have $100 to spend on your grow, add air. I highly recommend something like this

I bought one of those, and it was really loud and ran hot. I still have it, but I replaced it with a whisper 150 which is nearly silent, and just around $30-35. It supports 11 air stones.

baker, if you're in the US, see if you can source some Garden Friendly Fungicide by Southern Ag. I've run DWC and RDWC systems for the past 3 years, always had rez temps in the mid 70's and never have any issues with pythium. I believe there's a thread in the hydro forum that goes into depth on how to use it.

Air pumps compress air, thus heat the air. Blowing hot air into your nutes will obviously warm them up much more than a small water pump and a waterfall setup for aeration.

Obviously a chiller is the best way to go and the return from the chiller can be made into a waterfall.

Hydroguard is a good way to run when nutes are hotter than it should be.

The reason cool water is needed is that cold water holds more oxygen
The best way to prevent root rot is to bubble the shit out of the water, which provides all the oxygen the roots need to thrive.
I've grown in water as high as 78 degrees and never had a rot problem, but I had an air stone in each bucket.
Just aerate the shit out of the water, and all will be good

Sorry for the late reply,thanks for the tips guys, im new to dwc so just being cautious. I dont have the money for a chiller unfortunately,plus im running a 4 bucket setup with just classic dwc, 4 air stones, 4 buckets,1 air pump,and buying a chiller for each bucket will cost a fortune. Ive been using the hard ice packs for lunch boxes placed inside of plastic bags as a leakage precaution (which ive never had happen and ive been using the packs normally for years)
So far its worked wonders to keep the water temp down,plus i picked up a cheap window ac unit that i use to keep my ambient temperatures around 68-71, which also helps keep the water in check. Even when im being lazy with the ice it stays around 68-70 in the res. No smelly water,and have my first set of true leaves. Once the roots poke their heads out of the net pot ill drop the water level an inch or 2 at a time until im at my final resting point then i think my worries are over.

That helps ease my worries alot. Next paycheck ill pick up some big boy air stones and maybe upgrade my pump as well. Everything i see says 63-68 is nearly perfect res temp. As long as i can keep it there ill be rocking. Thanks my friend!

Wassup bro !!!! My res temps in my rdwc run between 77-82 will be adding hydroguard in case I run into any future problems!!! Hope this make you feel a lil better lol

I actually managed to cool my ambient temps enough to bring my res temp down to about 64-67 so i think all is good. Hope all goes well for you bro.

Would Hydroguard screw around with nutrients like beneficial microbes etc..?

Hydroguard is beneficial bacteria. It doesn't mess with your nutrients. Southern Agriculture Garden Friendly Fungicide is the same stuff but cheaper for most.
