Biogreen CO2 Tablets

Feed Every Root Zone a Direct Hit of CO2

Biogreen CO2 Tablets are effervescent tablets designed to dissolve directly in the reservoir or feed water, releasing a concentrated burst of carbon dioxide right where the root zone can use it. Rather than relying on a bottled gas system or a burner to raise CO2 levels in the air, this is a simple drop-in approach that works alongside your existing feed regime in any medium — soil, coco, rockwool or clay pebbles.

Each tablet is formulated with an additional 1.2% magnesium sulphate, so it tops up a commonly overlooked micronutrient at the same time as delivering CO2, without disturbing the EC of your nutrient solution. Growers running sealed or semi-sealed rooms often find aerial CO2 enrichment alone doesn't reach the root zone quickly enough — this tackles that gap directly, working through every stage from rooting through to the final weeks of flower.

• Effervescent delivery dissolves in around 90 seconds and stays active for up to 48 hours
• Dosed at one tablet per 200 litres of reservoir water for straightforward mixing
• Contains 1.2% magnesium sulphate to help prevent Mg deficiency alongside CO2 delivery
• EC-neutral — will not skew your existing feed strength
• Works in any medium — soil, coco, rockwool and clay pebbles
• Usable through the whole cycle, from rooting and vegetative growth into flowering

How to Use

• Reservoir dosing: add 1 tablet per 200L of nutrient solution
• Timing: drop in at each reservoir change or top-up for continuous effect
• Duration: each tablet remains active in solution for up to 48 hours
