ORP Control, Lowering levels

Hello! This group is always so helpful, and I thank everyone in advance.

I’ve been googling and googling about controlling ORP… there’s a lot of good information out there, but it’s all geared towards raising ORP levels and not lowering them. One site mentioned adding organics but not really any specifics. I’m just not sure what product to buy to use in my automation for lowering the levels.

Any help is always appreciated!

Adding a simple microbe product, such as Fish Sh!t or Tribus, should help. The bacteria further breakdown the nutrients available in the soil and make them more easily consumable by the plant roots.
