Looking good dude!!!! So I normally use Great White, as it was always readily available at all of the local stores, but my favorite store finally started stocking both Mammoth P and Recharge.. I went to buy some Recharge and he gave me a decent-sized sample of Mammoth P for free (probably because I feel like I keep him in business sometimes).. Anyway, these are my before and after pics.. The bigger plants are all DP (AutoUltimate, CindyJack, TD), smaller ones are all Dinafem Auto WWXXLs.. I hit them with a dose of Recharge last week.. Watered them yesterday with Mammoth P.. They literally ALL grew at least 2"+ overnight..

Keep in mind; this is considered a "water-only" grow, in the sense that I built the soil, and don't even really need anything else, just tap water.. I'm gonna use the Mammoth P for the rest of this grow and see if it's worth it versus the Recharge.. Maybe, maybe not.. Regardless, I think it definitely does help!!!
EDIT: So you know, those pictures are a week apart.. But still, explosive growth, for sure!!!
