Frequently Asked Questions

When and where is this formula meant to be used?

It's built for maintaining plants in garden center and growing facility settings, providing fast green-up and foliar expansion for all outdoor grown plants. The balanced 20-20-20 ratio also supports excellent root and shoot growth alongside that foliage response.

Why does this formula have such a high urea content?

The high percentage of ammonium and urea nitrogen (43.6% urea) is what drives the fast green-up and foliar expansion this formula is known for. That nitrogen form works quickly on foliage, which matters for maintaining plant appearance in a retail or production setting.

Will this fertilizer affect my growing media's pH?

Yes, it's an acidic formula rated at 555 lbs. CCE, meaning it will lower growing media pH over time with repeated use. That acidifying effect can be useful when working with alkaline irrigation water, but growers should monitor pH over an extended feeding program.

Is this suited for indoor plants as well as outdoor?

The batch's own labeling specifies use on all outdoor grown plants, so it's positioned primarily for outdoor production rather than indoor use. Growers with indoor crops should confirm suitability against current label directions before applying.
