I personally had a few ph issues with my promix. I had to flush the plants every two to three weeks which was a little bit to early for what I thought. I would add some lime to the promix If i use it again. I heard Sunshine Mix 5 is almost the same as promix just has a slight advantage when it comes down to PH buffers. I had a 50/50 mixture with perlite making flushing them a breeze:hippy:
Not to mention beautiful root structures.
jtsik330 Reviewed by jtsik330 on . Pro Mix Pro Potting and Seeding Soil So I was wondering if the 2 cu. ft of Pro Mix Pro potting and seeding soil would work as soil for vegging/flowering in addition to it being used for seedlings. I have Pure Blend Pro Bloom for flowering nutes, and Pure Blend Pro Grow for vegging nutes w/ superthrive. Will this work? I'm going to add 2:1 pro mix to perilite also. Any suggestions? Rating: 5
