Can I use hydroguard and great white together?
I don't see why not? I found I get super results from botanicare rhizo blast when I use it with it's GH counterpart Rapidstart. Ran out of one once and had enough of the other to make up the difference. Plants loved it.
ok thanks Mark
remember less is more
Great White doesn't dissolve in water but its great for Coco Coir. Orica is the sister brand for water grows, it works well but Tribus kicks its ass in water and coco.
