Using CO₂ tabs (carbon dioxide tablets) is one method growers sometimes use to supplement carbon dioxide for cannabis plants, especially in small grow setups. Here’s a quick breakdown of how they work and whether they’re effective:
How to Use CO₂ Tabs:
Dissolve in Water: Drop the tab into water (usually 1 tab per 5 liters).
Apply to the Soil or Reservoir: The CO₂ is released and absorbed by the surrounding air or water.
Ventilation Consideration: Use them during the light cycle when your grow tent or room is closed, as CO₂ escapes quickly with ventilation on.
