well i have just used voodoo and pirannah and it has defo made a difference, got a bit bigger yield. but my roots are like i have never seen. they are over 1 inch thick all over the gt404 nft tray. where as without they were say 1cm thick. worthwhile to me but a also use co2 which also makes a big big big diference.
steve.442 Reviewed by steve.442 on . addatives when you add things like humic and fulvic acid, sensizym, b52, silicone, voodoo juice and pirannah. the last 2 are root enchancers. does this increase your ppm and if so should they be taken in to account or first get your nutes to say 1000ppm then add all these additives which will increase your tds but not actually of increased your nuterient strenth. if i followed the advanced nutrient programme my tds meter would show higher ppm than wat the nutrient programme actually says it will be. one Rating: 5
