Activated Carbon DIY refill set. To refill two Minigrow filter cartridges yourself.
The Activated Carbon refill set includes:
- Two bags with ca 120 grams Activated Carbon pellets
- Small funnel
- Refill instructions
Activated Carbon is the filter medium used in the Minigrow filters. Replacing the filter medium is recommended after every 2-3 grows.
Refilling your cartridge is not a complex job, but requires some time and workspace. Assume it to take an hour of work the first time.
Alternatively, if you don’t like to do the refill job yourself, buy complete filled cartridge.
