Super Fast Delivery
Received this quickly and I appreciated that. I technically haven't started using it yet because I'm in the process of fixing my hydroponic system but directions are simple on the bag and when I'm ready to use it, I am set.

JACK'S 20-20-20
JACK'S 20-20-20 was an emergency purchase when I couldn't Order the amount of Organic Fertilizer required for my garden. I chose it because it contains live cultures/enzymes so I figured it couldn't be to bad. My annuals loved it.
