Cyclonite Reviewed by Cyclonite on . ph - cant get it right whatup guys, this is my first real grow and i went dwc. i got 2 lowryders with 2 gallons of water. they sprouted and everything but i cant get the ph stabilized. i got some powdered ph down but i dont know what kind it is cuz it came second hand ina kit. im experimenting in empty gallon jugs with tap water for now but the problem is the ph goes down exponentially instead of just a little after following exact directions. does it even out eventually or should i just get some new liquid ph down Rating: 5
