i will tell you all the nutes i've used and my experience with them...
i used technaflora's BC line for a grow.. just had a sample pack.. which was enough to get me through... had good results.. the grow itself was a little flaky... but i could tell a huge difference using the nutes over prior grows were i didnt use them (i used nutes.. just mainly teas tho)... i probably wouldnt buy the line again... not because of preformance.. just because i personally liked what i moved onto better...
after the technaflora i went with GH and have used it for a while.. its a good line... good results.. easy to use... has all the additives you may want to use.. but works good as a stand alone system as well... 2 and 3 parts for whatever you want...
i am now making the gradual switch to advanced nutes... i am either sticking with GH or AN.. but i need to get to the AN line to see the difference.. i am hoping it will be good.. i've heard NOTHING but praises and good things about the line.. plus its tailor made to grow "our kind of plants".. its posted all over their site.. they cant say what "our kind of plants" are on the site to keep it legal.. but i think we all know...
its been kind of unfair comparisons also.. everytime i used a new nute i added a bunch of extra shit to my grow.. new lights.. new hydro system.. new exhaust.. even new location.. so i cant be 100% sure that my findings with technaflora vs GH are right.. or even in the end what those two verse the AN does.. but something tells me, that with the experience i have, i should get a good idea of how they worked comparitvely tho..
