Well, to be honest they always do what they have to but i have not used any others before so, for me in specific they do what they have and i think they are pretty much unique because they have a perfect mix of what they need, they last long and if you use it correctly you get great result plus no need to make a mess with tons of nutes, its simple and easy! Im thinking yeah you might want to add some other stuff to your plant but if you want to run the basic, this two do the match super fine!
