Won a sample and loved it!

Never heard of this before but I won it in my grow group last November and been a customer since. Works great but I wish they had a bigger three pack cuz I'm buying the 5 gallons. Still, loving it.

Directions for Use

  • 💧 Shake Well: Ensure Holland Secret Grow is well mixed before measuring.
