## Questions & Answers

**Q: How should I install the CO2Bag?**
A: In a dry place higher than plants but not directly above them. If you have a ventilation, hang the CO2Bag on opposite corner of a green room.

**Q: How does it work?**
A: Make a few holes through the top of the bag. The powder inside starts to release carbon dioxide for your plants.

**Q: At what temperatures does the CO2Bag work?**
A: Recommended temperature is +25 ºC (77 ºF) ->

**Q: How do I store the CO2Bag before using?**
A: Store in a cool, dry place below 20 ºC (68 ºF). Keep away from heat and moisture, as they trigger the organic activation process inside. If activated prematurely while still sealed, the generated CO2 cannot escape, causing the bag to swell.

**Q: Why does my CO2Bag smell like ammonia?**
A: A slight ammonia scent is completely normal! It is a direct signal that the reaction inside the bag has activated and is generating CO2.
