DWC question

First question in years. I’ve always been a grow in dirt guy but was curious about DWC that I haven’t found anywhere else.
Is water temperature that important? I have my space with temps around 73 lights on and around 66-67 lights off. With that much water in a bucket would water temps fluctuate that much and under those conditions, and be harmful for the plant?

Thanks!

Set a bucket up with a air stone in it and monitor the temperature.

I have 5 rdwc systems and I use chiller on all of them. Dwc is all about everything being easily accessible and abundant to the plant, thats including oxygen. The colder the water the more oxygen it can hold.

I have ran sterile and with beneficial bacteria, I prefer the beneficials because I can use kelp and humic

Yes, I get that but I rather not get too much into this. I was given a basic set up but I don’t want to acquire anymore cost trying to figure out how to keep the water under 65 degrees. If I’m wasting my time I’ll just continue growing in soil.

It's a gamble. Worse case scenario, take a few empty drinking water bottles, throw them in the freezer. When frozen, throw one in the res. When thawed, switch it with another. Repeat.

Because of my work schedule I can’t really monitor it like that. I did see that suggestion on another thread. But it’s why I do soil grows since there is more wiggle room if there is an error. Water temp is literally the only factor I can see that keeps me in soil.

Really curious if any other users grow/grew under similar conditions and what their experiences are/were.

I've done it. Like I said, it's a gamble. I've been lucky. I've had my res hit 73. I keep a lot of airstones, and I use bleach. It's not ideal or suggested, unless you're willing to take the risk.

I will say this, the growth rate is fucking awesome. You can grow bigger, faster, if you know what you're doing.

I’ve been growing since I was a teenager, and I’ve come along way since then. Haha.
I have literally everything I need to get going but a answer to the water temp *potential* problem.

there was a guy here that grew veggies outdoors in AZ in DWC and used southern ag bacteria (he turned me on to it).

there is more DO in colder water but plants like warmer water. kinda a catch 22

No, I understand that from everything I’ve ever read.

My point in my post is I don’t want to waste my time trying to figure out how to keep the water temperature below 65 degrees in a 5 gallon bucket. In my conditions I wouldn’t think that should be an issue (+8 degrees tops) but what do I know since I’ve never tried it.

Does anyone actually have real world experience of this?

also, purely subjective. I had a buddy that ran a ebb and flow system. We would compare our dirt vs hydro and we always thought mine had a better taste to it (when comparing clones) Also, not proof of anything just two random guys opinions. Also, to add, absolutely nothing wrong with the hydro.

I would consider that method except he grew multiple plants whereas I just grow one or two for my wife and I.

73 degrees.... like I said. It can be done.
