CO2 Pro LED 500 ml 33PRO is a liquid biostimulant designed to activate plant metabolism in cannabis cultivation under LED lighting. It promotes photosynthesis and cellular respiration, helping to maintain dynamic growth and balanced flowering in indoor cultivation.

LED lighting creates specific conditions in the substrate, where drying is slower and root activity may be limited.
CO2 Pro LED 500 ml 33PRO, within the Fertilizantes 33pro range, has been developed to stimulate transpiration, nutrient absorption, and overall metabolic activity.
Thanks to a formulation based on fulvic extracts and metabolic activators, the crop shows a greater water and nutritional demand, a clear sign of an active metabolism.
The 500 ml format is practical for small crops or controlled trials without altering already established fertilization programs.
CO2 Pro LED 500 ml 33PRO is a universal biostimulant for growth and flowering phases, formulated to optimize the use of available CO₂ in the crop environment. The action of the product improves photosynthetic efficiency and cellular respiration, promoting more homogeneous development under LED systems.
This product is part of the bio fertilizers, providing metabolic support without modifying the basic nutrition scheme. It is an interesting option for growers looking for cheap fertilizers for cannabis adapted to the current demands of indoor cultivation.
The application of CO2 Pro LED 500 ml 33PRO is done by diluting 20 ml per 100 liters of water along with the rest of the usual fertilizers. The product should be added after the silicate and the nutrient bases to ensure proper integration.
Continuous use promotes greater transpiration and more uniform substrate drying, helping to maintain root oxygenation. It is recommended to suspend application during the last two weeks of flowering. Doses can be adjusted according to genetics, environmental conditions, and crop response.
The composition of CO2 Pro LED 500 ml 33PRO is based on an NK solution enriched with fulvic acids. It includes nitrogen in nitric, ammoniacal, and urea forms, along with potassium, essential elements to support an active plant metabolism.
The high content of fulvic acids stimulates the biological activity of the substrate and promotes interaction with mycorrhizae and Trichoderma. The product has a pH between 5 and 6, an approximate density of 1.28 g/cm³, and total solubility in water, which facilitates its use in different cultivation systems.
The price of CO2 Pro LED 500 ml 33PRO makes it an accessible option for growers looking for an effective biostimulant in compact formats. It is ideal for those who value cheap fertilizers for cannabis without giving up a technical formulation adapted to LED lighting.
CO2 Pro LED 500 ml 33PRO is available at Hydroponics Blanes, a trusted Grow Shop specializing in nutrition and cultivation systems. As a Grow Shop in Spain, it offers technical advice, discreet shipping and a wide catalog to buy fertilizers online safely.
CO2 Pro LED 500 ml 33PRO is an effective tool to activate cannabis metabolism under LED. Integrated with other Fertilizantes 33pro, it promotes a constant growth rate, greater water demand, and a visible plant response throughout the cycle.
