I use bio bud from g.o... its an organic and allegedly veganic bloom boost with a low n-p-k and dilution rate. It also allegedly put emphasis on creation of essential oils
I thought canna was a good enough product but their nutes are expensive, high dilution rates, and I didn't like that I had to buy their special bottle opener for the 5 litre coco a+b. Not bashing canna, great product but not for the recipients of my work or me.
With the g.o. I get far less stretch, tighter nugs, and more nose. I believe I get about 15% less weight but the finished product was easier to trim and flawless. And it saves me money and is ecologically sustainable are also 2 nice perks.
The g.o. sample I had tested at 9.36% terpinoids on analytical 360 (they post every test online if your not familiar), most test in the 3-6% range from what I've browsed through on their website with a few that are 9-12%
I sat down and picked their brain for maybe 20 minutes and I got some useful information from the guy. When you go and add silica, sugar, molasses, co2, or supper phospates and ultimately thinken your cell wall, your sample will test lower because your adding weight to the leaf and not to the thrichomes. The thc, cbd, cbc, n cbd %'s reflect properties in weight in the oils in ratio to the weight of the sample given.
Hope that helps or gets some gears turning.
