Optic Foliar Overgrow, 4 L RTU

Ready-to-Use Full-Spectrum Foliar Spray for Daylight Application, 4L

Most foliar sprays carry a warning against applying them in direct sun, which limits when a grower can actually get a foliar feed onto the crop during a normal workday. Optic Foliar Overgrow is a ready-to-use, multi-purpose foliar spray formulated to be applied in full sunlight without burning leaves, supplying a full spectrum of NPK, micronutrients, vitamins, sugars, amino acids, and B1 in one pass.

This 4L ready-to-use size is sized for growers running a regular foliar spray program across a moderate number of plants.

Frequently Asked Questions

Can I really spray this in direct sunlight?

Yes, Overgrow is formulated to be applied in full sunlight without burning leaves, unlike many foliar sprays that carry a low-light-only warning. That flexibility lets growers fit foliar feeding into a normal daytime work schedule.

What does Overgrow supply?

It supplies a full spectrum of NPK, micronutrients, vitamins, sugars, amino acids, and B1 in a single ready-to-use spray, rather than targeting one nutrient category. That breadth is what makes it a general-purpose foliar feed rather than a stage-specific one.

Do I need to dilute this before use?

No, it's sold ready-to-use, so it doesn't require mixing or dilution before spraying. Just shake and apply per the label directions.

How often should I apply it?

Follow the label's application schedule for your crop and growth stage; as a full-spectrum foliar supplement, it's meant to complement a base root-zone nutrient program rather than replace it. Overapplying a foliar feed will not substitute for a properly managed root-zone program.

Is this a complete replacement for root feeding?

No, it's a foliar supplement meant to work alongside root-zone nutrition rather than replace it entirely. Skipping root feeding in favor of foliar spray alone is not recommended.
