High-output LEDs are a serious investment for your customers. But without enough CO2 in the air, plants can't use all the light those LEDs produce. In a 1.2m x 1.2m tent running a 720W Omega Black, that's about 37% of the light going to waste. Here's why it happens, how to explain it at the counter, and the simple fix from TNB Naturals.
Let's take a closer look 👇
🌱 Light and CO2 – The Two Ingredients of Photosynthesis
Plants build new growth from light, water and CO2. Light provides the energy, and CO2 provides the carbon that becomes new leaves, stems and roots. If one of them runs short, it sets the limit, and adding more of the other won't push growth any further.
Indoors, that limit is often CO2. Normal air holds around 400ppm (parts per million), and plants in a busy grow room use it up quickly.
📉 Where the 37% Comes From
At standard atmospheric CO2 (around 400ppm), photosynthesis tends to level off at roughly 1,000 µmol/m²/s of light. This is measured as PPFD, the amount of usable light landing on the canopy each second.
A 720W Omega Black in a 1.2m x 1.2m tent delivers around 1,600 µmol/m²/s. Without extra CO2, roughly 600 of those 1,600 can't be used, which is about 37% of the light.
Your customers have paid for that wattage, but they're not getting the growth back. Raise the CO2 and plants can put more of that light to work. TNB reports up to 30–40% more growth at higher, usable CO2 levels.
💬 How to Explain It at the Counter
- Light is the energy, CO2 is the building material – a bigger light needs more CO2 to match
- More light isn't always more growth – at normal CO2, light beyond roughly 1,000 µmol/m²/s goes to waste
- CO2 protects the investment – it helps customers get the full return from the LEDs they've already bought
🌬️ How TNB The Enhancer Works
The Enhancer by TNB Naturals adds CO2 to a grow space without the cost and complexity of a full CO2 system. There are no tanks, regulators or electricity. Just add lukewarm water to the canister, give it a shake, and it starts releasing a steady supply of CO2.
Key features
- No tanks, regulators or electricity
- Add lukewarm water and shake to activate, then shake daily for the best results
- One 1L canister covers up to 144 sq ft (around 13m²)
- Each canister lasts up to two weeks
- Recharged with a 240g refill pack
Each canister lasts up to two weeks and then takes a refill, so it's a steady repeat purchase for your store. It's also an easy add-on for any customer buying a high-output LED.
