How much did you guys apply of the HH? I did 2 cups per 25 gallons of mix. So 2 cups per hole in my case. You know what's funny, the guy at my local hydro store says everyone loves it but me. But I don't trust "everyones" judgement. Maybe they just want to believe in it or have nothing to compare it to, I don't know. But what I do know is it doesn't cut it for me. My work speaks for itself. I owe my turn around last season to the way I used the FF product. I'm sure it could have worked with lots of different brands but I have FF so dialed in and I like the stuff, works for me.
