Frankly, I think most flavor and terp supplements are money wasted. Never used terpinator, seen great reviews..
For me, spending money on premium genetics is better spent cash.. honing in my skills every grow has been the single biggest factor to put my terps and flavors on a whole nother level..
I use basic nutes, good lighting, keep environment in check..
I don’t believe these additives are a magic bullet by any means..
