I use it, I foliar with it 2-3 times during flower. Not economical to use in the tank IMHO, at 2-3 ml per gallon foliar a bottle lasts forever. i also use Gravity and purpleMaxx, and on rare occasions bushmaster, all foliar.
I've used Gravity in my DWCs during my last grow and felt pretty "meh" about it. Of course I've only had one grow with it and I plan to use it again in my next grow but overall I'm not sure if it's worth the hype or money.
Ive heard good thing on yeild increase making buds harder but also that the smoke was harsher and inturn messed up the taste... never used it though... own a bottle of bushmasters, purple maxx, and gravity... shoudl give them to someone....
Use at 1ml a gallon from 28 days
2ml 42-50 days
Use with your normal nutes and if you allready dont use it add 5ml per gallon of Blackstrap Mollasses when using Gravity
This shit seriously works but do not OD on it, and yes even when used properly it will take away some from the finished product but only slightly in terms of flavor it takes nothing away in potency. Now it will pack on serious weight to your buds, Gravity is one of the few products out that I give the Wow factor and I am a pessimist. This product will take weak yielding sativas and make them decent yielders it will make indicas donkey dick yielders. What it takes away in terms of flavor it makes up for with weight.
Purple Maxx is a dud never saw anything out of this product and I grow a few purple strains.
bushmaster is my fav. one. gravity is cool, it does what its supposed to, but I feel it def. degraded the look/smell/taste...but boy were they fat and hard. take the advise and dont use on a heavy indica...rot/mold for sure.
I basically tell everyone that these humboldts own products are good, but they have to be used EASY, and its all about finding that sweet spot. man, you should see what some of these knuckle heads are doin...gravity with phosphoload, big up powder...all at once! = super shitty bud. unless u really know ur ratios and ur flush and u really know ur shit.
I foliar fed a few times w the snow storm ultra...semmed to all some trichs for sure.
