Co2 Bags - Exhale
Exhale CO2 bags let your plants breath, naturally.
Plants growing indoors under artificial light often lack enough CO2 to efficiently photo-synthesise.
When plants are able to maximize the process of photosynthesis, the result is larger plants with larger yields.
The exhale CO2 bags are generating carbon dioxide right from purchase.
One way breather patch releases carbon dioxide 24 hours a day for 6 months.
