dubious claims on this product since environment, plant genetics and bio chemistry are the deciding factors of how much and what
terpenes are present....
sure there are substances that help this process, N-P-K Ca, Mg, S, B, Mn, Zn, Fe, Cu and Mo do alot of that by themselves!
And yet many people are seeing measurable results. Go figure.
I agree with you about the factors that ultimately determine terpene levels, but I'm not sure exactly what your overall point is. What's so dubious to you? Plant genetics would indeed determine terpene production
potential in any given individual. So? Nobody is claiming that Terpinator 'creates' a plant's potential; it just enhances the existing potential. How? Via biochemistry, as you state. The plant metabolizes whatever is in Terp and reacts by increasing resin and terpene production. A plant without existing resin and terpene traits isn't going to magically create those things if you use Terp.
As for listing basic nutrients and minerals as you did... yeah. That's just basic plant health. Proper nutrition. One would assume/hope we all already have that covered, along with proper environment. Basic/proper nutrition is not typically considered a 'terpene enhancer' - it is just the basic diet that you should provide for your plants - so I'm not sure why you are using it as a comparison. It's more of a foundation for reaching a plant's genetic potential.
I have been using Terpinator at 20 ml/gallon and definitely see enhanced resin production. I personally haven't seen any significant weight gains; just a small amount, probably due to the resin increase. As someone using the BioCanna line I have never had any lack of flavor or smell, so no real opinion on that.
The bottom line is this: this product may or may not work when used with various food regimens, and also may only be really effective with certain genotypes. I don't think generalizing is going to help. Each person would need to try it with their own regimen to determine if it is worth it.
It isn't a magic bullet. In my experience, though, it seems to at least pay for itself several times over, so there's
that.
Products like BioBiz's Top Max have a similar resin-boosting effect, and I have seen some serious weight gains with Top Max. I am going to try a side-by-side next round: Two plants of four types, one of each type getting Terp and one of each getting Top Max. I will report back here if anyone is interested.
