Optic Foliar Transport — Foliar Spray Wetting Agent for Lights-On Application
Best for: Growers who want to spray nutrients, fungicides, or pesticides during lights on without leaf burn, and need their foliar solutions to actually work
Our thoughts
Transport does something most foliar additives can't: it lets you spray while the lights are on. That alone saves hassle. But what actually matters is that it works. Opens the leaf, lets the active ingredients in fast, and means you can use quarter-strength fungicides and still get results. One that pays for itself quickly if you're doing regular foliar work.
Optic Foliar Transport is a foliar spray delivery agent that opens the stomata of your plant leaves and drives active ingredients deep into the mesophyll layer. Unlike traditional wetting agents that just coat the surface, Transport allows nutrients, fungicides, and pesticides to penetrate and work properly — which means you can use them at a fraction of the strength and still get full effect. And here's the kicker: you can spray with the lights on. No more special dark-cycle visits. No leaf burn. Just proper delivery when it suits you.
How it compares
Transport sits at the premium end of the foliar additive market for good reason.
-
RAW Yucca, Aqua Burst, Coco Wet: Budget alternatives, but require dark-cycle spraying and don't penetrate as effectively
-
DIY solutions (Dr. Bronner's, saponin extracts): Cheaper upfront, inconsistent results, risky with beneficial microbes
-
Transport: Lights-on capability, mesophyll penetration, allows quarter-to-half strength actives, no pH adjustment needed
The efficiency gain — using less pesticide and fungicide per treatment — means you're not overpaying for convenience. You're actually saving money on chemical inputs over time.
Usage guidance
Standard mixing
Add 7.5ml (1.5 teaspoons) of Transport per litre of water. For seedlings and cuttings, drop to 5ml per litre. During main grow and bloom cycles, stick to the full 7.5ml per litre.
With lights on
This is the whole point. Spray during your normal lights-on period. No risk of leaf burn. No need to time visits around dark cycles. Just mix, spray, move on.
With fungicides and pesticides
Transport lets you use actives at quarter to half strength and maintain full efficacy. On first application, use the other product at quarter strength and Transport at full strength. Test on a few plants before the full spray. Once you're confident, dial it in and watch your input costs drop.
Tank mixing
Works with any nutrient, fungicide, or growth enhancer. Mix with distilled water where possible. Don't adjust pH — Transport handles that. Store mixed solution in a cool, dark place away from lights.

Who this is for
- Indoor growers managing pests, mildew, or disease — want to reduce chemical load without losing effectiveness
- Time-constrained growers who can't schedule dark-cycle spraying visits
- Anyone running multiple rooms or high-maintenance crops where foliar input costs add up fast
- Growers correcting nutrient deficiencies and needing rapid uptake without waiting on root absorption
- Hydroponic and commercial indoor operations looking to improve spray efficiency
Particularly suited to setups where operational convenience meets chemical efficiency.
Our take
Transport does exactly what it claims. It opens the leaf, drives the active ingredients in, and lets you spray when it suits your schedule — not the other way around. Factor in the efficiency gain (using quarter-strength actives with full results) and the cost of this bottle pays for itself within a few applications.
Good time to buy while stock lasts. One of those products that sounds like a gimmick until you actually use it, then you wonder how you managed without it.
