This is true 100% that the warmer you can run the water the better and faster the pants will grow up to a certain temp. I think the sweet zone would probably be a water temp between 73-76 but that's also the danger zone. I've been running RDWC since 2007 and have never gone without chillers. I have never tried your water fall method, I like to stick several air stones with each plant and keep the water at 68 degrees. I do have a nice waterfall on my return line in the controller bucket though along with another larger air stone. This method has yielded 2.25 lb plants in a 13 gallon bucket!I did side by side testing and waterfalls were far more robust and resistant to root issues than air stones.
You're welcome to disagree but having grown hundreds of pounds with both over hundreds of runs I can say unequivocally that waterfalls work better. The warmer water even helped my plants metabolise faster and grow better.
Your grow, your choice.
