Protekt is a great thing, but its also bullshit, its a simple salt, thats it, silica is the only additive I would suggest people use with every hydro line, its not that its cheaper to mix your own its the fact that all it is is potassium silicate and water with a Dynagro label so if you call ANs Rhino skin bull shit then you have to call Protekt bullshit also, Protekt is stronger than Rhino skin but not by much and they are the exact same thing, magpro and KLN are a complete joke. My point was that all manufacturers make bullshit products, AN doesnt own the market on bullshit, they simply give the sheep what they want. Sensi grow is hands down my favorite nute AN makes, I have yet to use Foliage pro but I have been meaning to, I honestly didnt expect the 2 1 ltr bottles of sensi grow to last so damn long but they did. Do you think Foliage pro as a 1 part in a perlite drain to waste scenario would be a good choice or would you stick with mixing grow/bloom? I used the grow/bloom a few years back, but not FP
