CO2 Fusion — Foliar CO2 Supplement Spray

CO2 Fusion — Foliar CO2 Spray Supplement

A unique approach to CO2 supplementation — CO2 Fusion introduces CO2 directly to plant leaves through a foliar feed, bypassing the need for CO2 burners, regulators, or sealed grow rooms. Also contains natural plant extracts delivering amino acids and sugars absorbed directly through the leaf stomata. For growers who want the photosynthesis boost of CO2 supplementation without the commercial-scale equipment.

Why growers choose CO2 Fusion:

• Foliar CO2 delivery — sprayed on leaves, absorbed through stomata, no burner or gas bottle needed
• No specialist equipment required — works with any standard pressure sprayer
• Increased photosynthetic rate — the benefit CO2 supplementation provides, without the complexity
• Amino acids and sugars included — broader plant support than pure CO2, provides a foliar nutrient boost too
• Works in any grow space — no sealed-room requirement like traditional CO2 supplementation
• Ideal for smaller home setups — where a burner or regulator doesn't make economic sense

Who it's not for:

Stop foliar feeding once flowers form — spraying buds risks mould. Spray only at lights-off or under LEDs at lower intensity; water droplets under bright HPS focus light and burn leaves. Traditional CO2 supplementation (burner + controller) is still more effective for commercial-scale grows with high lighting intensity. For small home grows, this is a genuine alternative.
