they do make things easy but you are paying for it. GH will hang up on you because they are the industry (all horticulture and botany) standard, but thats ok if you know what you are doing, then there should really be no need to use a "canabis specific nutrient" (whatever that really means as there are thousands of different strain of canabis which all require subtle differences). if you are interested enough to make the effort and learn about the entire process then feeding your plants will seem much more simple and you will see right through the marketing used to entice new growers into buying these products. but i will say that AN does make a few products which are quite as good if not better and reasonably priced as their competitor. Bud candy for instance has been one of my favorite additives, i have tried sweet and humboldt honey and i like the results from bud candy better. i use GH as my base with the lucas formula and now i am trying out jungle juice, which is a GH knockoff made by AN which will be priced slightly cheaper. in full disclosure i got all three 1 liter bottles of jungle juice (grow, micro, and bloom) for free so why not use them. i am also tryin sensizyme instead of hygrozyme which i normally use because sensizyme is actually cheaper. some of their products i would never buy or even think of using like rhino skin (botanicare silica blast is 1/3 the price) wet betty (which i am definitely convinced most buy for the picture), tarantula or scorpion juice. the last two do not show promising enough results to be worth the huge price tag.
