A better alternative to AN?! Oh that's easy. Maple syrup, battery acid, bleach, xenon gas, liquid mercury, ricin, engine oil, a chainsaw, a two-stroke weed eater. All those things are better for your plants than AN nutes. GH makes some really good stuff, but I was disappointed when, a few years ago, they diluted their formula making people buy more to get the same nutes as before. Just for that reason alone I switched to TechnaFlora, and I'm so glad I did. I'm sure everyone has their preference, but if you contact Technaflora and ask for a sample, they will give you a few small bottles to test and you can see for yourself. The best stuff I found by them to replace necessary nutes is their B.C boost, B.C bloom, B.C grow and awesome blossoms. Stuff like lime, cal-mag, ph up and down, equalizer, neutralizers, all those are pretty much the same formula no matter who you go with. But fox farms has some good stuff too. In my honest opinion, not that my opinion matters where facts are being sought, I would much prefer organic with tons of boosters. Technaflora line and fox farm soil would make for a decent grow
