I had a great time with AN products especially the pH perfect line and it saved me a lot of time by locking pH at 6.3-6.5 so I would highly recommend it.
I was using an Amazon LED light before this Wich are really bad so I can't really tell the efficiency of this one but when I switched to EasyGrow, my flowers started fattening by the days so I'm very happy about it.
Overall a good high for the day or night, I feel lightened and thoughtful. It's also the best flavor I've tasted so I'm not disappointed at all.
