CO2 Fusion sprays it straight onto the leaf where it matters. No gas bottles, no ventilation losses, no worker safety concerns. Clever bit of kit.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eCO2 Fusion is a \u003cstrong\u003efoliar spray designed specifically for hydroponic growers\u003c\/strong\u003e. It delivers dissolved inorganic carbon (DIC) and plant-active amino acids directly to the leaf surface, addressing a fundamental gap in soil-less growing: at least 10% of the carbon plants need comes from the soil as dissolved carbon. Hydroponic crops get none of that, which is why relying on passive air diffusion alone leaves you short. Spray this on and you're giving your plants the carbon they'd naturally get, without the complications of CO2 gassing systems.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eCO2 Fusion sits in a niche — it's not a general foliar feed, it's a carbon-specific supplement designed for hydroponic systems.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003evs. CO2 gassing:\u003c\/strong\u003e No ventilation losses, safer for workers, works in any room setup, no gas bottles to manage\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003evs. general foliar sprays:\u003c\/strong\u003e Specifically formulated for the carbon deficiency problem in hydroponics, not just micronutrients\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003evs. doing nothing:\u003c\/strong\u003e Plants can show up to 30% improved growth rates when carbon levels are optimised — this delivers that without the hassle\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn short: if you're running hydroponics without CO2 gassing, this fills a real gap.\u003c\/p\u003e\n\u003ch3\u003eUsage guidance\u003c\/h3\u003e\n\u003cp\u003eCO2 Fusion is straightforward to use.
