Master CO2 1000 ml Cannaboom – CO2 Bioactivator for LED
Master CO2 1000 ml Cannaboom is a next-generation bioactivator designed to improve photosynthetic efficiency and accelerate nutrient assimilation, helping to convert the same light and watering into more useful biomass and a more uniform flowering. At Hydroponics Blanes, an online store specialized in fertilizers for cannabis, it is a very interesting tool for indoor crops with LED where the goal is to make better use of PAR without nutritional imbalances.

Its base of organic carbon with 18% fulvic acids acts as a chelating vehicle: it promotes the transport of nutrients such as N, K, Ca, Mg and chelated iron (Fe-EDDHA), helping to maintain more consistent absorption and a more stable nutrient solution in terms of pH and EC.
This product does not provide gaseous CO₂. Its approach is bioactive: it enhances internal processes related to the use of carbon and photosynthesis to improve the overall performance of the crop, especially in high-density and LED environments.
Helps stabilize the rhizosphere and reduces the risk of lockout due to salt buildup. It can be integrated with fertilization irrigation while maintaining proper pH control.
In coco, where Ca/Mg management is critical (especially under LED), it helps improve the mobility and stability of the nutritional plan, monitoring drainage and return EC.
In hydro/aero systems it integrates easily into the reservoir, promoting a homogeneous solution and rapid absorption. It is recommended to monitor pH and renew the solution according to routine.
Standard dose: 0.2 ml/L of water.
Schedule: from week 3 of growth to week 5 of flowering.
Frequency: in each light watering or 1–2 times per week according to nutritional plan.
Dosage: 1 ml/L.
Frequency: 1 time/week, from the start of cultivation until week 6 of flowering.
Best practices: apply with dimmed light or at the end of the photoperiod, avoid wetting advanced flowers and maintain gentle ventilation.
Master CO2 easily integrates into Cannaboom charts and can be combined with products aimed at each phase:
At Hydroponics Blanes you can buy Master CO2 1000 ml Cannaboom to boost photosynthetic efficiency and assimilation in crops with LED, soil, coco or hydro. A versatile tool for demanding nutrition programs, with use by irrigation and foliar.
