Does anyone know the ph of promix potting mixes. I was just curious as I may try a grow in some. It has the basics ( sphagnum,perlite,lime).

Before any wiseguy answers, I do have a ph meter!! I just want to see if anyone knows off hand?

How have your grows gone? When do you start feeding?

The dolomite lime gives it a neutral ph..I've used it since I started growing...great stuff...

I'm not a manure or compost fan...if you do use these watch your N levels as they can get too high...

"BM1 All Purpose Professional Growing Mix" PH= 6.5. Just measured it. Pretty close to neutral.
