GrowPax Sizing Tips
Don't think of it in gram weight. Think in terms of capacity. We control a volume of space, selecting a size requires understanding how much volume you need to control.
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.
