reservoir temperature

So from research I have ran into keeping the res temp around 68 degrees is optimal temp. For a few reasons

One is for optimal root growth the other is for algae and bacteria.I have also ran into keeping the grow deck around 78 degrees.

Before I tried to control the temp in the res my deck was about 81 and my res fluctuated between about 78 to 85.

When I drop it to 68 my leafs droop down and touch my grow deck.

I know a lot are gonna say 'listen to your plant.' But I really don't want to cause problems with bacteria.

Am I putting my plant into shock dropping it that low and I should give it a few days to get used to it?*

Or should I just continue with what I was doing??

Any input would be awesome.

Give them a dy or so to adjust to the cooler temps, or maybe bring the res temp down gradually over cpl dys to allow them to adjust.
Either way i would def go with the cooler res temp

I used ice bottles for years and it created rapid temp drops, with never an issue. How are you cooling the res?

At first I was using PhD ice cubes but I was diluting my nutes so I went and got some tiny rubbermaid storage containers. I have 10 of them Anson interchange them out 2-3 at a time

Dude, 2 liter coke bottles or any size soda bottle filled with water.

Ya that is were my problem is I am using an aerogarden and to actually fit my reservoir I have to use the small guys

However I took nick88's advice and my little girl is doing great. My res is a steady 67 deg. And my grow deck is 78.

I started mine out in my UC system with a water temp of ~50 at most! It has taken a good week to raise the temps up to 60! The fact that I overfed them didn't help much! I just wanted to share to all that low water temps are not the end of the world! High ones usually are!

66-68 for me and using a chiller to regulate temp

When I do a rez change I use water directly from a well (i know should let it sit !!) and it is in the low 50's. The plants dont seem to mind and have never had an issue with droppy leaves. It usaually takes a day to get up to 68ish in 100L res.

Im going to get flamed for this, but understand my climate is ridiculously hot, i have ambients between 25 - 30 celcius. My res temps are always around the same as my cabinet temps, around 30-35 celcius,
I have read that using h2o2 and other minor additives is my best protection against root issues. If you can control your climate then yes, your harvest times are shorter and your yields are larger. It is definently better to control your temps if you can.
I have 2 air lines directly under my root ball, plant started thriving when i moved the airlines directly under it.

I saw first hand that oxygen levels are terrible in warm water, and when you get the oxygen levels up the plant just explodes.

In summary, if your in a hot climate, do the best you can with what you got, if your in a reasonable climate, maximise your great position, im envious of people who live in 20 celcius climates.

Come down under, and burn baby burn!

You do what you gotta do diablos! I shut the grow down in summer due to excessive heat in shed lol.
