GrowPax are different than your average moisture regulator. Because they scavenge oxygen, they need to be handled differently than other products in this category. See how we can help.
Over 60 years of experience, deeply rooted in niche science, has brought us GrowPax
GrowPax Testing Guidance
Please read handling instructions first. GrowPax activates once it is removed from its pouch. This foil pouch is designed to give extreme protection for three years. Once removed, the packets activate within two hours.
Handling Instructions for Testing Labs
The pouches can be resealed if all packets are not used. Press air out (or vacuum seal) with heat to preserve product efficacy. If packets have been exposed for more than an hour, throw away any leftovers. Do not use packets that have been exposed to air for more than an hour.
Each packet has an oxygen capacity. A 2 gram packet has 50CC of capacity, a 4 gram packet has 100CC of capacity, and an 8 gram packet has 200CC of capacity. For sizing, please consider the volume of your container, how full it is, and the density of the product you are trying to protect. A 100cc bottle filled mostly to the top will still have oxygen, both in the headspace of the package, and in the flower – depending on density. Select a packet that you know will have the capacity to scavenge the correct amount of oxygen.
These packets are different. Treat them like an oxygen absorber, they have a finite capacity for oxygen and through technology we have established a two-hour activation window.
Testing Guidance for Labs
Ensure packaging material is suitable for environmental control. Unsealed containers cannot protect the interior of a package from the outside environment. Some types of materials are not good oxygen or moisture barriers, in this event, a larger packet should be used to handle oxygen or moisture ingress over time.
Testing should be done with homogenous mixtures of flower to ensure proper results. For accuracy of tests, best results can be achieved by mixing flower from the same plant into different packages.
Different flower can provide different results, each component may be affected by different circumstances even if it came off the same plant. Use care to ensure testing mixes are consistent throughout.
