Not trusting my math, I measured in mls last night-
1ml Gravity/1qt H2O (7.00 pH, 0.00 ec)
ec- minus 0.004 (almost nil)
pH- minus 0.70 (7.00 ->6.30)
No doubt, kelp is acidic- I use liquified kelp to lower pH in solutions that have enough room for the ec/ppm bump. Although the numbers will vary somewhat from brand to brand, 7ml liq kelp/qt H2O will lower the pH 0.70 (7->6.3) and raise the ec by 1.2 (0.04->1.20 If my figures are right, that would mean that Gravity provides 7x the acidic strength of liquid kelp and does so w/ only a minimal amount of DS's in solution. In other words, Gravity packs a lot of acidic punch in a small container. The other ingredients-phosphoric acid and the B's are complementary nute/addies w/ any kelp product and while they will help to enhance the effect of the active agent/s, they wouldn't be the major player.
This has led me to *hypothesize* that the source of the active ingredient in Gravity is exactly what the label says it is- kelp. (Truth in advertising? Now that would be a novel concept.) While I'm certain that the company has experimented w/ kelp strains and come up w/ some favorites, my thought is that the secret is in the processing- the "proprietary" extraction method- what gets separated out and what's done w/ what's left behind.
I have no ambition to uncover anyone's secret formula. I say congrats to the enterprising spirit who came up w/ a little gem that does what it says it does- makes buds denser and harder. Denser, harder = bag appeal. That being said, Gravity is not an integral part of my nute/addie program but it's good to have on hand to firm up buds that are wispier than I'd like them to be, particularly during the final couple of weeks before harvest because of the low ec.
Nice post! I agree that honesty is the best advertising, but it IS a novel concept. I just look at so much hype in ferts and addies and wonder if they are worth the price. Thanks for this info. I want to try it on my SSSDH, SLH, Chocolope, and other Sativa dom strains to see what it does for me! I'm excited to try it as it sounds like a great product. Good thread though, informative about the products potential and real world results. That's the only downside to organic products IMHO, the inability to get a ppm/EC reading.
Cheers,
