how to harvest and store marijuana seeds

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.

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

A female cannabis plant that has received pollen from a male will produce many seeds over the course of its maturation cycle. Upon senescence, when the female plant is fully mature and ready for harvest, its seeds will be ready for stratification and collection.

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.

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.

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

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.

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.

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

Pollinated buds look quite different to regular sinsemilla. They usually don’t have as many rich trichomes and don’t form into large colas. Instead, they’re usually smaller and a lot more bulbous.

But it’s important to remember that male cannabis plants are just as important as their female counterparts. Male cannabis plants produce pollen like other male plant varieties which germinate female buds to create seeds.

Remember, only the bud sites that come into contact with pollen will develop cannabis seeds. You can choose to apply pollen to parts or all of your female plant. You’ll also want to make sure you directly touch the pistils/hairs on a bud site to ensure the area is well pollinated.

HOW TO USE CANNABIS POLLEN

When it comes to storing cannabis pollen, moisture is your worst enemy; if your pollen gets wet it is literally useless.

If your cannabis seeds don’t meet this description, let your plant develop a little longer. Some cannabis plants can develop mature seeds really late into their flowering cycle. If that’s the case, make sure you keep your plant alive with plenty of light and nutrients.

Some people like to store their pollen together with plain flour using a 1 part pollen to 3 part flour ratio. This helps absorb any moisture and also make pollination easier by increasing the volume of the pollen collected. Alternatively, you might want to try storing your cannabis pollen with silica gel packs

By this time, the developing buds on the female plants will have white wispy hairs. These are used to naturally collect pollen from the wind in the wild.
