Why Choose Optic Foliar REV

Optic Foliar REV addresses a specific nutritional gap: when plants are pushed into accelerated growth by a stimulant like WATTS, their foliar nutrient demand increases beyond what a standard root-zone feeding program delivers. REV fills that gap through direct leaf absorption.

• Micronutrient and vitamin supply during high-demand phases. REV delivers micronutrients, organic vitamins, amino acids, carbohydrate sugars, and vitamin B1 directly to plant tissue — nutrients that are critical building blocks for flower development, quality, taste, and flavor.
• Maintains vigorous growth rates. Plants treated with WATTS grow markedly faster. REV is formulated to sustain that growth rate by keeping pace with increased nutritional demand, resulting in greener and more lush foliage.
• Designed for the Optic Foliar system. REV works as part of the broader Optic Foliar product line. It is best applied with TRANSPORT, which acts as a carrier to improve foliar absorption and reduce the risk of leaf damage from direct concentrate application.
• Supports flowering and crop quality. In addition to vegetative support, REV provides key building blocks specifically mentioned for flower development and final crop quality, including taste and flavor profiles.
• Simple foliar delivery. As a foliar-applied solution, REV supplements the root-zone feeding program without requiring changes to reservoir chemistry, pH, or EC targets.

Best Uses for Optic Foliar REV

Optic Foliar REV is targeted at growers already using foliar programs or working with strains and techniques that produce rapid vegetative expansion and heavy flowering loads.

• Post-WATTS application cycles. REV is specifically designed for use after applying Optic Foliar WATTS. Once WATTS accelerates growth, REV steps in to provide the additional foliar nutrition needed to sustain that pace without the plant becoming nutrient-stressed.
• Vegetative stage supplementation. Growers pushing heavy vegetative growth — whether through high light intensity, CO2 supplementation, or dense canopy training — can use REV to supply the micronutrients and amino acids that rapid tissue development demands.
• Transition to flowering. During the transition from vegetative to bloom, REV helps plants maintain the nutritional reserves needed to initiate and sustain flower sites, contributing to higher-quality yields and improved crop flavor profiles.
• Indoor and greenhouse crops where foliar feeding is part of the program. REV integrates cleanly into existing foliar schedules. Growers who already apply foliar sprays for calcium, magnesium, or silica can add REV as part of a structured foliar rotation with WATTS and TRANSPORT.
• Situations where root-zone uptake is limited. When roots are stressed, recovering, or operating at reduced efficiency, foliar feeding with REV provides a direct pathway to deliver nutrients to plant tissue without relying on root uptake. If you are working with a root-zone stimulant like Advanced Nutrients Tarantula, REV can complement that program by addressing foliar nutrition simultaneously.

Optic Foliar REV vs Similar Foliar Nutrient Products

Optic Foliar REV occupies a specific niche: it is a foliar-delivered micronutrient and amino acid supplement rather than a standalone base nutrient or bloom booster. Most foliar sprays on the market are either pH adjustment aids, calcium-magnesium supplements, or broad-spectrum foliar feeds not tied to a system. REV is different in that it is formulated as a complement to the WATTS growth stimulator, meaning its ingredient profile is calibrated to support the elevated nutritional demand that WATTS-treated plants exhibit.

General-purpose foliar additives such as kelp extracts or standalone amino acid products can provide some overlap in benefit — organic vitamins, amino acids — but they are not designed with WATTS-accelerated growth rates in mind. If you are not using WATTS, REV can still function as a micronutrient and vitamin foliar supplement, but its primary design intent is as part of the Optic Foliar system. Growers evaluating stand-alone micronutrient or humic and fulvic options should consider whether foliar delivery fits their program; products like Earth Juice Hi-Brix Molasses serve a different function (root-zone carbohydrate delivery) rather than direct foliar micronutrient supply.

Compatibility

Optic Foliar REV is designed for use within the Optic Foliar product system and is compatible with most indoor and greenhouse growing environments.

• Growing systems: Compatible with hydroponic, coco coir, soil, and soilless growing media. REV is applied as a foliar spray, so it does not interact directly with reservoir chemistry, pH levels, or EC targets in the root zone.
• Optic Foliar WATTS: REV is formulated as a direct companion to WATTS. The intended workflow is to apply WATTS first to stimulate growth, then follow with REV to supply the nutritional demand that faster growth creates.
• Optic Foliar TRANSPORT: REV should be used with TRANSPORT, which serves as a carrier and penetrant that improves foliar uptake while reducing the potential for leaf surface damage when applying concentrates directly. Do not apply REV as a concentrate directly to leaves without dilution or a carrier product.
• Other base nutrients and additives: Because REV is applied as a foliar spray rather than added to the reservoir, it can generally be run alongside most hydroponic base nutrients without altering reservoir formulation. Growers using diverse additive programs — including root inoculants such as Heavy 16 Roots — can integrate REV into their foliar schedule without conflict.
• Growth stage: REV is applicable during both vegetative and flowering stages, as it provides building blocks for both foliar health and flower development.

Usage Guidelines

Optic Foliar REV is a foliar spray additive. The following guidelines are based on its role in the Optic Foliar system and general best practice for foliar nutrient application.

• Always use with TRANSPORT. Optic Foliar recommends applying REV together with TRANSPORT. TRANSPORT improves foliar absorption and helps the spray solution penetrate the leaf surface more effectively. Do not apply REV concentrate directly to leaves without a carrier.
• Apply during lights-off or low-light periods. For indoor growing, foliar sprays are typically applied when lights are off or during low-intensity periods to prevent leaf burn from the combination of moisture and intense light. Follow the application timing guidance on the Optic Foliar label.
• Spray to coverage, not saturation. Apply the solution evenly across the leaf surface, including the undersides where stomata are concentrated. Aim for thorough coverage without dripping runoff.
• Follow the Optic Foliar dosing schedule for REV. Dose rates and application frequency are specified on the product label and on the Optic Foliar feed chart. Because this is a foliar additive with a low NPK ratio (0.5-0.6-0.021), dose accuracy matters more for timing and frequency than for reservoir volume calculations.
• Monitor plant response. After applying REV following WATTS treatments, observe growth rates and leaf color over the following days. Healthy green coloration and continued vigorous growth indicate the foliar program is working as intended.

How to Apply Optic Foliar REV

1. Prepare your spray solution. Measure the recommended dose of REV per the Optic Foliar feed chart. Combine with Optic Foliar TRANSPORT in the proportion specified on the product label. Mix in clean, pH-adjusted water.
2. Check timing. Schedule the application for lights-off or a low-light period. Avoid applying when grow lights are at full intensity to reduce the risk of light-related leaf stress.
3. Fill a clean sprayer. Use a dedicated foliar sprayer that has been cleaned and is free of residues from other products, particularly anything that could react with the nutrient solution.
4. Apply evenly to foliage. Spray the solution evenly across all leaf surfaces, including the underside of leaves. Stomata on the lower leaf surface are a primary site of foliar absorption.
5. Allow to dry before lights come on. Do not interrupt the drying process by turning lights on prematurely. Allow the spray to dry on the leaf surface before resuming the normal light cycle.
6. Follow the Optic Foliar system schedule. REV is most effective when used as part of the structured WATTS + TRANSPORT + REV program. Refer to the Optic Foliar feed schedule for timing and frequency guidance specific to your growth stage.
