Calcium Sulfate | CaSO4 | 1lb

DIY GH Booster

Posted by Anderson P. on Sep 9th 2016

Order arrived packaged well and in great condition. Ferts come prepackaged in a resealable baggie. Would definitely order again.

Had 5lbs of K2SO4 and some MgSO4 already, so I bought some of this to make my own GH Booster per the 1:3:3 ratio on the site. Ferts I ordered appear very pure and mixed right in when added to water.
