I dont gavs anything to compare with but I'm pretty happy with the BioGreen line and going to use them in my next diaries. Plus points for me are ease of use and almost no salt build up. Negatives would be in my opinion the A+B doesnt have enough Nitrogen. I had to supplement it early in this grow and I'm suffering quite a lot in my current grow. Once you know what to expect then it's a simple fix.
