Grow Hack: Prevent Mold During Growth, Curing and Storage

Mold afflicts cannabis to such an incredible degree that an entire subspecies of the plant had to evolve with a different anatomy to prevent mold growth. How ubiquitous is mold in cannabis? It’s roughly as common as under-cured pot, which means very common. Check out this simple trick to stop mold growth in its tracks for live buds, curing and storage.

Mold spores exist everywhere; even the highly purified of outer-space satellite factories still contains traces of dust and mold. If a growroom has filters in place in its intake ducts, the interior air should, in principle, contain less mold spores than outside air. Despite the even minor presence of spores, mold may still proliferate if conditions are too humid. In the proper humidity levels, live plants exude natural products that keep mold growth at bay in its own living tissue, but once the plant dies during harvest, the entire crop is at risk of mold colonization.

Humidity control during curing is of utmost importance. The grower must assure that the relative humidity of the air remains around 50-60 percent, a good range to prevent mold growth on the one hand, but not so low that the buds dry out so fast they attain an unfavorable consistency. Even with humidity levels in the air in the proper range, as long as the buds retain above 12.5 percent water by mass, they will still be at risk of mold formation. These humid flowers generate local pockets of humid air within the anatomy of the bud, which is why constant air circulation is a must.

So you got your hygrometer, dehumidifier and circulating fans, and you think everything is perfect, but one fateful day you take peak in the calyxes of your beautiful buds and you see the white spindly hairs of hyphae bud-rot. What could have gone wrong? Even under perfect atmospheric conditions, bud-rot can still proliferate because cannabis buds simply make the perfect environment for mold. This problem requires a little help from our good friend technology.
