harvesting and drying cannabis seeds

It can be bittersweet saying goodbye to old genetics, but sometimes it’s unavoidable. You can take clones or keep a mother plant, but those aren’t ideal because they require a lot of care and maintenance, especially if they aren’t producing flower.

Male cannabis plants will produce pollen several weeks into their flowering cycle. Once their pollen sacs have opened up and released, the plant will begin to senesce and eventually die. It is important to collect pollen right as the sacs are beginning to open up, as this is the time pollen is most viable.

The Benefits of Long-Term Storage

Fresh seeds should have a germination rate close to a 100%, whereas older seeds will see a significant drop off over time in their ability to germinate.

Out in the open, pollen may be viable for one or two weeks under normal conditions. However, when frozen and sealed, it can last up to a year and even longer. Pollen is more unstable than seed and even under the most optimal conditions, it isn’t expected to have as long of a shelf life.

Long-term storage requirements for seeds and pollen are similar. Both require cool, dark, dry, and oxygen-deprived environments for optimal preservation.

There are different opinions and methods about storing your seeds for a long term – in frizzer, refrigerator or room temperature.

When RH is about 63-65% inside the humidor and buds are ready for jarring, mature seeds start falling off. At this point start pulling out the seeds gently and chopping the buds on small bits. When all seeds are out, DRY THE HUMIDOR BOX VERY WELL AFTER BUDS ARE JARRED AND PUT THE SEEDS BACK. The point is seeds to dry on lower RH.

So about a month after harvest usually have 99.99% germination rate and store seeds properly tagged in plastic vials with some rice in the frizzer in air-tight containers. Make sure to remove all small bits vegetable matter and grade your seed before storing them.

After harvest, seeds continue to develop during drying and curing and if you pull them out fresh and quickly dried without some more dry and cure they don’t germinate very well. After harvest trim slightly and dump the buds in a humidor box for 12-14 hours for initial cure to even their humidity and prepare for slow dry. Then put them in brown bags for 2-3 days to dry a bit (usually moisture decreases significantly for that time) and then move them back to the humidor box to continue slow dry and cure for about 7-10 days.

SHORTLY: DON’T DRY CANNABIS SEEDS QUICKLY and don’t store them immediately after harvest.

The process of growing cannabis does not stop at harvest time. Properly drying and curing your fresh cannabis stash is paramount to prevent mould contamination from taking place. These procedures will also result in buds that taste better and offer a superior high.

Drying, as the name suggests, involves drying fresh buds so they contain less moisture and can be smoked or vaporized properly. Curing, on the other hand, involves storing your buds in closed containers over a period of at least two weeks. This helps develop the flavour and aroma of your buds as they mature.

WHAT’S THE DIFFERENCE BETWEEN DRYING AND CURING?

By placing individual buds on a drying rack—or hanging entire branches in a drying room—you’ll reduce the water content of your buds by 10–15%. This process removes water from the outer layers of each flower, but you’ll need to cure your stash to rid moisture from deeper within the buds.

Freshly harvested cannabis buds contain a significant amount of moisture, which needs to be dealt with before smoking. Why? First, smoking fresh buds serves up harsh hits with little flavour—if the buds are able to ignite at all. Removing moisture helps to tone down the harshness and let the terpene profile shine. Second, fungi thrive in dark and moist conditions. By drying your flowers correctly, you’ll dramatically reduce the chances of mould striking your stash.

Ahhh, harvest time. After watching your ladies grow and flower, it’s finally time to collect your hard-earned buds. But before you can enjoy a toke of some homegrown Kush, you’ll need to dry and cure your freshly harvested weed. Below, we’ll share our answers to some frequently asked questions on the drying and curing process, so you can maximise the flavour and potency of your stash.
