Hey IDS....So to put it simply Grow More is the only 30% concentration of Up or Down in the market...It is federally regulated and we are the only company authorized to sell it at the retail level. You'll notice that botanicare has just came out with a Ph up and Down that's 29% and 28%; basically the most anyone can do without getting popped by the feds...I'm not sure of the concentration of other companies though, as all too often in the Hydro industry happen, companies won't discuss what's REALLY the concentration in the products. I swear the Hydro industry and the retail labeling is worse than in the 1920's when guys were selling 'patented' drugs out the back of Model T's 
There's also been some issues with the actual concentration of other products in the market, as most are phosphoric acid (down) and Potassium hydroxide (Up) and have to be diluted down from the 75% concentrates or the 30% we sell. So basically they are cutting for example a 75% down to 5 parts water and 1 part concentrate to reach a 15% concentration....But mostly I can't say ours is any more or less special from any other brand because it's just basic chemicals/raw materials. We don't use dyes like some others do...So yeah it will require less to the same thing; raise or lower the Ph...Let me know if you need anything else about that...
