I got a bottle of Bloom Phat half off to try. I used on one clone of jack herer and did not use it one the other. The plants are next to each other under a light mover. Visibly, 20-30% more on Phar plant. I have not cut and dried so have only visual cues to tell me so. Incidentaly, the phat plant finished yesterday, while non phat plant is still going with a week left. Pistilate formation schedule were entirely different though being from the same mom, in identical soil and environment. I was told by a reliable source in new zealand the ooze plants in a side-by-side had trichomes down the stems and they got 25% more bubble hash. I wouldve tried Ooze but my shop got it in ten days late for this crop.
I personaly feel no nute lineup is needed in entirety to grow world class pot. That said, I always feel there is room for improvement in all things man intervenes in. There is something to be said for paying eccesively to support advertising. Some of a products costs are associated with r & d and my kiwi pal says the yellow bottle people did tons. Of both.
Proof is in replecable results so next crop I'm trying out a couple lineups in same room with same clones. I just like to see the difference between hyperbole and holy cow myself.
