Oxygenating hydro

What's the deal with water temperature, then? My bucket is sitting among coco bags. Why would the temperature of my bucket be different than my bags, which I have never worried about the temperature of the coco?
 
Speaking form experience, I run my air pump 24/7 and swap out my nutrient solution once a week. I start my seedling in a rapid rooter in a slotted cup which allows root growth into the nutrient solution. The cup is surrounded by activated clay pellets. I run 1 plant with 3.5 gallons of nutrient solution in a 5 gallon container.

I think the difference is that a bag of coco has some natural aeration vs water which has very little with out it being prodded.
 
I was thinking more about evaporation.
My bags and coco are 68°-70°. My bucket is 74° outside and the water is 76°, prodded. Plenty of fan action throughout. The bags evaporate from every square inch, but the bucket is pretty well closed save a few errant holes.
A commonality between all the hydro-type, lidded bucket setups is that it is all light absorbing black plastic. I wonder... what are thoughts on white plastic? Maybe even a double chamber?
Allenpro's Kratky method might be the answer to my original question about how long to keep a pump on: It doesn't need to be 24/7. It might even be a thing when it comes to temperature. ​
Today's experiment will be checking water temperature when the lights are off. Tomorrow's experiment will be temperature when lights are off and the bubbles are turned off.
 
If someone can work out how to put an aeroponics system in a solo cup you will win the challenge hands down. It cannot be beaten for growth and yield.
 
Misting in a Solo cup full of roots, probably not. I think your leprechauns would even have a hard time working that out.
How about ebb and flow?
 
Ebb & flow is just so yesteryear, it's a hangover from the 70's. Misting a root mass and then pumping air through between misting sessions is high tech stuff of legends, leaders forged in the fog of aeroponics mist for the betterment of all mankind!
 
Riiiight... you do aeroponics, B-doobie.
I'm too poor to be hi-tech. I did hi-tech when I worked. These days it's all about ghetto.
 
It is DWC, I think. Aeroponic, DWC, hydro, ebb and flow. It's a bucket of nutrient juice with an air stone. I was only talking about coco as a 'why this but not that' example.
