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.\u003c\/p\u003e\u003cp\u003eEach 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffervescent delivery\u003c\/strong\u003e dissolves in around 90 seconds and stays active for up to 48 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDosed at one tablet per 200 litres\u003c\/strong\u003e of reservoir water for straightforward mixing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContains 1.2% magnesium sulphate\u003c\/strong\u003e to help prevent Mg deficiency alongside CO2 delivery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEC-neutral\u003c\/strong\u003e — will not skew your existing feed strength\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks in any medium\u003c\/strong\u003e — soil, coco, rockwool and clay pebbles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsable through the whole cycle\u003c\/strong\u003e, from rooting and vegetative growth into flowering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReservoir dosing:\u003c\/strong\u003e add 1 tablet per 200L of nutrient solution\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTiming:\u003c\/strong\u003e drop in at each reservoir change or top-up for continuous effect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuration:\u003c\/strong\u003e each tablet remains active in solution for up to 48 hours\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFormat: effervescent tablet\u003c\/li\u003e\n\u003cli\u003eDose rate: 1 tablet per 200 litres\u003c\/li\u003e\n\u003cli\u003eDissolve time: approximately 90 seconds\u003c\/li\u003e\n\u003cli\u003eActive duration: up to 48 hours\u003c\/li\u003e\n\u003cli\u003eContains: 1.2% Magnesium Sulphate\u003c\/li\u003e\n\u003cli\u003eSuitable media: soil, coco, rockwool, clay pebbles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"BioGreen","offers":[{"title":"Tub of 100","offer_id":53500727001354,"sku":"NUT-BIOG-010-01","price":41.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/LondonGrow_Nutrients_Biogreen_CO2Tabs.png?v=1786377717","url":"https:\/\/hydrocropshop.co.uk\/products\/biogreen-co2-tablets","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
