Good Job Joe Fresh!
I have been using this mix for a few years and it has been doing well for me, dont know the exact breakdown in Parts or percentages but here she goes pretty simple.
1 Bale Pro-Mix BX
1 4.0 Cu Mother Earth Size 4 Extra Chunky Perlite
1 30lb Wiggle Worm EWC
Thats it if someone could breakdown the math on that I would appreciate it. Here goes a pic minus the the wiggle worm, I was trying a new cheaper EWC company at the time of this pic. Lets just say I am back to wiggle worm.
