I use a Milwaukee 600 digital pen. Been using it since last year and its never more than .1 off. A good little pen for 20 bucks. Like i said i usually only test and ph one jug at a time so that way i know the ph is right. The light warrior should work by itself as a seed starter correct? All it looks like to me is peat and perlite. T
pushit Reviewed by pushit on . Fox Farm soil questions Ok, so Im finally graduating to Fox Farm soils for my next grow. Im planning on going from Rapid Rooters to Light Warrior to Ocean Forrest. I just want to make sure I do the right ph since ill be growing in different mediums. I asked about the Rapid Rooters before and I was told 5.8 should be fine for them. Should I put 5.8 ingoing ph for the Light Warrior also since its peat based even though its phd adjusted at 6.3-6.8? Then 6.5 once its in Ocean Forrest. I would usually experiment but around Rating: 5
