Yep, I've read that article before...very good!
I have no doubt about the benefits of molasses, even in hydro. I wouldn't use organic nutrients in higher water temps for the same reason I wouldn't use molasses - organic nutrients are meant to attract/grow beneficial bacteria/fungi, which like lower temp/higher DO in water. But they will also attract the anaerobic pathogens that like higher temp/lower DO conditions if those conditions are present.
Chemical nutrients can be used in any conditions, but are REQUIRED in high temp/low DO conditions IN MY OPINION. Your chance of failure goes up, but you CAN grow successfully in these conditions...100% successfully if you grow in a STERILE environment. This is why I recommend chemical nutes and H2O2 in high water temp grow conditions...so you can maintain a sterile environment without the NEED for beneficials OR the danger of pathogens.
Of course, somebody will probably come and say how they've grown in high-temperature organic nutes for years without problem. To which I would say: smoking cigarettes doesn't always mean you'll get cancer...but it sure does increase the risk!
