PhotoBoost — more yield, powered by light

PhotoBoost is a concentrated foliar spray that helps your crop photosynthesise more fully. Its carbon quantum dots (CQDs) help the leaf capture more light, and its key minerals run the photosynthesis engine — turning the sunlight your crop already receives into more energy and sugar.

It's used on jasmine rice (KDML105), commodity/RD-series rice, corn, sugarcane, durian, cassava, fruiting vegetables (chili, tomato, eggplant, cucumber) and leafy greens (lettuce, kale, cabbage). It works best where light is the limit on yield — not where water or major nutrients are badly short.

One 100 mL bottle covers about 5 rai of C3 crops across the season. C4 crops like corn and sugarcane run at half dose, so one bottle stretches to about 10 rai. Use the calculator on this site to get the bottle count for your area.

It's a foliar spray — mix it into water and spray to wet the leaves on both sides. The calculator shows the mL per rai per spray (a knapsack tank is roughly 20 L/rai). Spray in the early morning or evening for the best uptake.

Spray at your crop's key growth stages — for example panicle initiation in rice, ear-shoot in corn, sucrose loading in cane, and flowering/fruit-set in tree crops. That's usually about 4–6 sprays per cycle. Pick your crop in the calculator to see the recommended schedule and the critical sprays.

PhotoBoost is classed as a biostimulant (not a pesticide). It is water-based with low acute toxicity, biodegradable, and has no residue or soil-persistence concerns. Wear normal gloves and eye protection when spraying.

It works alongside your fertiliser — it doesn't replace it. PhotoBoost is a photosynthesis amplifier, not an NPK fertiliser; there's no NPK in the bottle, so keep your normal soil fertiliser programme. What it does replace is your foliar micronutrients (zinc, magnesium, iron, manganese, copper) and a generic amino-acid biostimulant.

PhotoBoost acts on photosynthesis after spraying, and a single spray gives roughly 2–3 weeks of effect — so re-apply at your crop’s high-demand stages.

A 100 mL bottle is 420 THB retail. Order or ask questions via LINE @livingroots. On top of the product cost, one bottle replaces foliar inputs and biostimulants worth about 550–1,050 THB/rai.

It contains carbon quantum dots (CQDs) that convert UV-blue light into red light chlorophyll can use, plus the minerals that run the photosynthesis chain: manganese (splits water at PSII), iron (runs the Cyt b6f electron chain), magnesium (chlorophyll core + RuBisCO), copper and zinc (electron carrier + CO₂-fixing enzyme), and potassium + silica (move sugar into grain/fruit).
