Marx,

I use a bubble wand in my reservoir and it works great. Lots of tiny bubbles everywhere. If you enjoy playing with the PH, add more air A small price to pay for more oxygen.

GluteusMaximus Reviewed by GluteusMaximus on . Identifiy the problem ~800 PPM CalMag + FloraNova Grow PH @ 5.6-5.8 at all times -- Skunk #1 -- These are clones under @ a little over two weeks of vegging - I did find algae in the res, so I changed nute solutions last night -- They are under 18/6 cycle -- Plants are getting progressively worse as time goes by. This seems to mainly effect the fan leaves... Rating: 5
