harvesting and drying cannabis seeds

A grower or breeder can also freeze the progress of a breeding project for months or years without losing any of the long, hard work. Endeavors such as phenotype hunting and maintaining desired mothers for breeding and cloning can all be saved for later through genetic preservation. This process is like backing up work on a hard drive.

When storing seeds, place them in an air-sealed container that doesn’t have any light leaks. Film canisters, medicine bottles (non-translucent), and any sealable storage jar will work fine. The idea is to reduce the amount of oxygen present in the storage space as much as possible. You can also add uncooked rice to the storage container, which acts as an absorbent, to reduce moisture content.

The Benefits of Long-Term Storage

Fortunately, preserving genetics for long-term storage is easy and will save time, money, and space in the long run. Through seed and pollen collection, you can hang onto those genetics that you can’t fully get rid of and safely store them for future use.

It’s important to continually practice germination testing to be sure your stored seeds haven’t lost all viability. To test this, periodically plant a seed and document its ability to germinate.

To collect seeds, it’s important to wait until they are fully mature and ready for harvest. Cannabis with seeds takes longer to mature than cannabis that only produces flower.

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.

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.

Drying your cannabis flowers serves several important functions that ultimately increase the quality and shelf-life of the end product.

WHAT’S THE DIFFERENCE BETWEEN DRYING AND CURING?

Get the answers to 9 of the most frequently asked questions about drying and curing cannabis.

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.

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.

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.

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.

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.

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.

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

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