Here is my opinion on gh nutes, I switched to hydro for the first time, using the lucas formula I have had success I have never eperienced before with gh nutes, (wich I bought after I had already spent lots of money on all the pure blend pro nutes and add ons wich I stopped using...) and everything has been super easy, if I ever get the nuts up to post a picture or 2 I will. But I have done far better in hydro with gh nutes than ever in dirt (obviously this is for me personally)... and I will never switch back to dirt again.
