Frequently Asked Questions

What crops does this formula work best for?

Crops that are sensitive to excess micronutrients thrive with this classic formula, thanks to its acidifying action that corrects an overload of growing media pH. That combination makes it a targeted choice rather than a generic feed.

What water types can this fertilizer be used with?

It's effective for all Water Types. Its acidifying action still applies consistently regardless of which water class you're feeding with.

Does this product have any special shipping requirements?

Yes, this 20-10-20 General Purpose formulation ships hazardous, so confirm your shipping method can accommodate that classification before ordering. This acidifying formulation's concentrated micronutrient package is what drives the hazardous classification, so plan shipping lead time accordingly.

How does the acidifying action actually work?

This formulation carries a rating of acidic 404 lbs. CCE with no urea, meaning it steadily lowers growing media pH over repeated applications rather than a single sharp correction. That gradual acidifying effect is what prevents the micronutrient overload sensitive crops react to.

What size and packaging is this listing?

It ships as a 25lb bag, supplied 80 per pallet, matching its acidic rating of 404 lbs. CCE. That volume suits commercial greenhouse feeding programs correcting pH drift on micronutrient-sensitive crops.
