Under Current Nutrients anyone used ?

Im giving the under current nutrients solutions a go in my next round of 32 plant count, 13 gallon bucket system by cch20. My setup is 18k watts. I ran heavy 16 last round and had great results. Im wondering if anyone has tried this nutrient line out and would like an input on how the quality and yield comes out.

Thanks, Anthony

Never used the nutrients solution but I love the look of their hydro systems.
