Watts Optic Foliar 60ml – Boost Light Efficiency & Plant Growth

Watts Optic Foliar 60ml is a concentrated foliar spray that transforms how your plants use light, turning every photon into faster growth, bushier foliage, and bigger harvests—safely and without leaf damage.

Ever feel like your grow lights aren’t delivering their full potential? You’ve invested in top-tier LED or HID lighting kits, but your plants still grow slower than expected, with pale leaves and weak structure. You’re not doing anything wrong—you’re just missing the key that unlocks your light’s true power.

Without a light-optimizing foliar like Watts, your plants waste precious energy. They struggle to convert light into growth, leading to stretched stems, delayed flowering, and underwhelming yields. You end up wondering if your setup is flawed—or if you’re just unlucky.

Watts changes everything. It’s scientifically formulated to amplify the Calvin Cycle and ATP production in leaves, so your plants absorb and use light far more efficiently. The result? Lush, dark green foliage, explosive vegetative growth, and earlier, heavier flowering—all while staying safe under direct light during application.

Why Watts Is a Game-Changer for Indoor Growers

Watts isn’t just another foliar—it’s a photosynthesis accelerator. While most growers rely solely on root feeding, Watts works directly on the leaf surface to maximize the energy your lights provide. It’s especially powerful when paired with high-output 1000W LED grow lights or HID systems, where light intensity is high but often underutilized by the plant. Watts ensures none of that energy goes to waste.

Whether you’re running a small closet grow or a full indoor tent, Watts delivers visible results within days: tighter node spacing, thicker stems, and vibrant green leaves that signal peak metabolic activity. It’s the secret weapon for growers who want professional-level performance without complicated routines.

Key Features and Real-World Benefits

• Boosts chlorophyll and chloroplast production – Your leaves turn deep green and capture more light, driving faster photosynthesis.
• Enhances ATP energy cycle in leaves – Plants convert light into usable energy more efficiently, fueling rapid growth.
• Safe to spray with lights ON – No more midnight foliar sessions; apply during your normal light cycle without risk of burn.
• Increases nutrient uptake from roots – Better light use means stronger demand and absorption of nutrients, amplifying your feeding program.
• Promotes early flowering and denser buds – Plants shift into bloom faster and pack on more weight during flowering.
• Clear light-blue liquid, no residue – Leaves stay clean, stomata stay open, and no post-spray rinsing is needed.
• Long-term mix stability – Combine with other foliars or nutrients and store for future use without degradation.
• Works with any light type – Optimizes output from LEDs, HPS, CMH, and fluorescents alike.

Common Concerns—Clearly Addressed

Growers often hesitate to use foliars due to past bad experiences. Here’s how Watts solves those worries:

• You think that foliar sprays burn leaves under lights. In reality, Watts is uniquely formulated to be photostable—spraying during your light cycle is not just safe, it’s recommended.
• You think that foliars are messy and leave residue. In reality, Watts dries clear with zero film, so stomata stay open and transpiration flows normally.
• You think that it’s too complicated to mix or store. In reality, Watts blends easily with other foliars and stays stable in solution for weeks when stored cool and dark.
• You think that it’s only for advanced growers. In reality, Watts simplifies growth—just add 7.5ml per liter and spray 2–3 times weekly for dramatic results.

How to Use Watts Safely and Effectively

Using Watts is straightforward, but following best practices ensures maximum benefit and plant safety.

1. Prepare your spray mix: Add 7.5 ml (1.5 tsp) of Watts per liter of water. For gallons, use 30 ml (1 oz) per gallon.
2. Apply during lights-on period: Early in the photoperiod is ideal—just after lights turn on. Never spray near electrical components.
3. Spray only the top leaf surface: Focus on upper foliage until lightly coated; no need to drench undersides.
4. Use 2–3 times per week: During veg and up to week 4 of flower. Reduce or stop during late bloom to avoid excess moisture.
5. Store properly: Keep the bottle sealed in a cool, dark place. Refrigeration extends shelf life significantly.
6. Pair with Transport for best results: While Watts works alone, combining it with Optic Foliar Transport enhances penetration and efficacy.

Frequently Asked Questions

Can I use Watts with other foliar sprays like pest control?

Yes! Watts is compatible with most IPM sprays, including organic insecticides and fungicides. Just add it to your mix at the standard rate—it won’t interfere and may even boost absorption of other actives.

Do I need to adjust the pH of my foliar spray when using Watts?

No. One of Watts’ advantages is that it works without pH adjustment. Keep your spray at natural pH for optimal performance and leaf safety.

Will Watts work under LED lights, or is it only for HID?

Watts works exceptionally well under all light types, including full-spectrum LEDs. It enhances the plant’s ability to use whatever light you provide—making it perfect for modern indoor grow tents with efficient lighting.

Can I use Watts during flowering?

Yes, but only up to week 4 of bloom. After that, humidity and moisture on buds can increase mold risk. Stop foliar applications by mid-flower to ensure clean, dry harvests.

Personal Experience of Pevgrow’s CEO (Alan)

I’ll admit—I was skeptical at first. Foliar feeding always felt like a hassle: timing sprays at lights-out, worrying about burns, dealing with sticky residues. But Watts changed my mind completely. I started using it on a test run of Strawberry XXL Auto under a 600W LED, spraying every other day during lights-on. Within 5 days, the difference was undeniable: darker green leaves, tighter internodes, and stems that felt like rubber. By week 3, they were 30% bushier than my control group. Now, I don’t run a single veg cycle without it. My tip? Always pair it with distilled water and store your mix in the fridge—it stays potent for weeks. And don’t overdo it; 2–3 sprays a week is plenty. Less is more, and Watts proves it.
