GrowPax Sizing Tips


Each GrowPax has a different absorption capacity, for large containers, multiple packets can be used, and sizes can be mixed and matched.

  • 2 gram GrowPax: 50cc
  • 4 gram GrowPax: 100cc
  • 8 gram GrowPax: 200cc 

For reference, a glass jar that is 5 inches high, and a diameter of 3 inches will have a capacity of about 120cc. If you use a 4 gram GrowPax in that glass jar your product would be protected.

An HDPE (a type of plastic) jar that is 3.75 inches by 3.5 inches will need a little bit more protection because the material allows more ingress. This jar would have a capacity of about 150cc. An 8 gram GrowPax should be used to project this container.
