@Stephen or anyone that knows…Just out of curiosity how long will that bottle last? What ppm level does the unit maintain with this in the unit? I do understand that different factors like plant size will play a role in ppm level I’m just looking for a rough idea

Hey @Mpower11,
Each bottle and refill pack will last about 2 weeks. Stay tuned for our CO2 Digital Meter video for more info on levels. It should be out in the next month!
Cheers,
Stephen
