Germination

The process in which a cannabis seed sprouts, which will eventually turn into a full plant.

How to germinate a cannabis seed

Cannabis seeds need three things to germinate: water, heat, and air. A great way to ensure successful germination is the paper towel method, which requires:

  • Two clean plates
  • Four paper towels
  • Cannabis seeds
  • Distilled water

To germinate seeds:

  • Soak four paper towels with distilled water; they should be soaked but not dripping
  • Place two of the paper towels on a plate
  • Place the marijuana seeds on the wet paper towel at least an inch apart from each other
  • Cover seeds with remaining two water-soaked paper towels
  • Cover with a second plate, upside down, like a dome, to create a dark, protected space
  • Keep seeds in a warm place, between 70-85°F

Seeds should germinate in 3-10 days. Check paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water.

If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud, and it won’t sprout.

A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.

It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.

I made sure to buy paper towells that had no chemicals or inks.
Any advice will be appreciated, thanks.

i use water from my faucet for every aspect of my plants. but i am on a flow well. no chlorine or bleach in my water. just minerals, and lots of sulpher (smells like eggs). good, natural, groundwater

I don’t soak or use paper towels and I have a nearly 100% germ rate within 3 or 4 days.

16 oz plastic cup, poke holes in bottom for drainage
Pro Mix (B’Cuzz, anything PH adjusted without nutes)
Distilled water
Glad Cling Wrap
Pen

1. Mix your medium with distilled water until it’s ready for planting – squeeze some lightly in your hand, it should retain its shape and the contours of your hand but not drip any water.

2. Fill the cup, covering the top and shaking up and down to get the medium compacted evenly. Fill to 1″ below top, pat down GENTLY.

3. Using the pen tip make a small hole in the center of the cup about 3/16″ deep.

4. Take the seed to good light and determine which end is scalloped (will open) and which end has the little dimple where it was attached to the plant (the hing). Place the seed gently in the top of the hole with the scallop side down, remove the refill from the pen and use the open end to fit over the seed and push down so it’s dimpled end is 1 millimeter below the surface. Use the tip of the pen to gently rough up the medium top and lightly cover the seed with 1 mm of medium.

5. Sprinkle 3 – 5 tablespoons of distilled water on top of the medium, soaking the entire surface.

6. Tear off a strip of cling wrap wide enough to cover the cup, tear the strip in two and use one half strip per cup. The good cling wrap will hug the lip of the cup and give you a great seal.

7. Put the cup in your flower room, if possible high enough to get direct light. This will give you a steaming effect, the inside of the cling wrap will become opaque with water vapor. The 12/12 cycle seems to help the seed split, I’ve found much better luck with this than 24 hours constant heat – perhaps because the heating and cooling in 12/12 closer mimics a natural enviroment.

8. Check the cup atleast 3 times a day – lights on/off/in middle – if the seed pops the surface and you don’t remove the cling wrap the stem stays bent for a few days. Filling the cup with medium to 1″ below the surface gives you some playing room, and space to add more medium if the stem needs support.

9. If the plant pops the surface and you have a white stem without the leaves you planted the seed upside down and you are looking at the root tip. If you catch it early enough you may be able to replant before the root dies.

10. Remember to label your cups.

Long winded and unasked for, but if anyone is having trouble with germinating this is a near idiot proof method.

Tips to Germinate Marijuana Seeds

We offer many decades of valuable information. Make sure you read all our tips and tricks, they will save you money and get you more female marijuana plants in your medical grow room.

Here are some basic rules many of you with common sense, may not know:

  • Do Not handle Seeds/Sprouts with bare hands, use gloves.
  • Use distilled water only. NEVER USE TAP WATER OR WELL WATER. Even if you boil your water, DO NOT USE IT. USE DISTILLED WATER ONLY OR Bottled Water will work fine.
  • DO NOT TRY TO GERMINATE YOUR SEEDS AT ROOM TEMPERATURE. YOU WILL HAVE A MUCH LOWER GERMINATION RATE.
  • ****** RAISE THE TEMPERATURE ONLY A FEW DEGREES ABOVE ROOM TEMPERATURE (78 DEGREES FAHRENHEIT, 25 CELSIUS, AND WATCH THEM ALL SPROUT. *********
    NOTE: SATIVA STRAINS LIKE IT WARMER.
  • ******* DO NOT TRY TO GERMINATE AT ROOM TEMPERATURE, LET THEM DRY OUT, THEN TRY AGAIN A FEW DEGREES HIGHERS. DO IT RIGHT THE FIRST TIME AND AVOID COSTLY MISTAKES. ********
  • DO NOT USE HUMIDITY DOMES, They PREVENT VITAL AIR EXCHANGE AND CAUSE MOLD TO GROW AND KILL YOUR SEEDLINGS. They only have one use, for CLONING.

Often, you acquire seeds in the mail. In this case :

  • In Hot Weather : Make sure you do not leave them sitting inside a mailbox in direct sunlight. This can raise the temperatures and actually “cook” your seeds, making your seed non-viable or drastically decreasing their germination rates.
  • In Cold Weather : Bring your seeds inside from the mailbox, and let them “defrost” for 3 days (72 Hours) before germinating. Do Not take any short cuts, wait a full 72 hours. Seeds are frozen during the winter in their native environment, and freezing during travel will not harm them.

STORAGE: How to properly store marijuana seeds

Freezing and Thawing repeatedly will lower your germ rates. Each time you bring your seeds out of the freezer, moisture from inside condensates through the shell of the seed and evaporates. Repeated multiple times, will eventually dry out the inside and kill your seeds.

Another issue is MOLD. Every time your seeds are wet on the outside from thawing condensation, you increase the risk for mold when you do decide to germinate. So do not store seeds in the freezer unless you plan on not using them for 1 or more years.

Most quality seedbanks will deliver your seeds in an airtight container with a few grains of rice, just large enough to fit the contents with no spare room. The rice is used to stabilize moisture/humidity levels and fill up the remaining space so only the smallest amount of air is part of the container. You can store them at room temperature like this for about 6 months. If you plan on storing them longer than 6 months, and less than a year, place them in the refrigerator in their sealed container.

TIP : Even if you don’t un-thaw your seeds from freezer storage, you cannot go into the freezer, open your container of seeds to take a couple seeds out, and then refreeze the rest immediately. Just by opening the container, you allow new moisture filled air into the container. This moisture and can damage your seeds and cause mold problems when germinated.

Room Temperature Storage : DO NOT store your seeds in direct sunlight, in a cabinet above your fridge, or dishwasher or a cabinet with lights built in below. Do not store near a radiator, fireplace, or heat vent. For example, a dark and cool spot in the basement works great.

Basic Germination:

You have a seed with a shell. Inside this shell is your root and food storage. The idea is to allow enough water to soak into the shell, so the seed is no longer dormant. The water will force the root inside to expand and bust out of it’s shell, at which time it will need a food source to continue growth.

PROS and CONS

Germinating marijuana seeds directly in your Growing Medium is a wonderful way to germinate most strains

POSITIVES : It will prevent any harm from touching the sprout and transfering it to it’s medium. Even professionals can kill sprouting seeds from mishandling them during transplant.

TIP: Because you hands carry billions of bacteria, you should never touch your seeds or sprouts without using sterile gloves or tweezers.

CONS: Planting directly in your Rock wool or Soil can cause problems. Soil can harbor bacteria that will kill your seeds, make sure you use a sterile soil with minimum nutrients. Big Block stores carry seedling soil which has the right amount of nutrients and is sterilized. Soil also dries out too quickly or grows mold if too wet.

I prefer to use a larger sized pot so it does not dry out too fast. And I don’t have to over water from fear of it drying out too fast.

Rock wool can have a higher than optimal PH level for seedlings, and using PH up and PH down can kill your seeds, because PH up and down are acids and bases. Seedlings cannot tolerate Acid or fertilizer (high nutrients) without dying. Seedling should only get a 5% nutrient mix.

The paper towel method is not a very good way to germinate seeds. It’s OK, and will give OK results, but it is not the best way. Paper Towels are not sterile, and can cause problems.

The Cup Method is good if you can transplant without damaging the sprouted seedling. You take a sterile plastic cup (that has never been washed, to avoid any soap residue) Take a disposable plastic beer cup, fill about 2 inches deep with distilled water. Drop in your seeds using gloves, never your bare hands (you don’t want to transfer anything to the sterile cup and water)

Now you have to wait and watch carefully. You do not want the sprouted seeds to stay in the water longer than they have too. As soon as you see that the sprout is 1/4″, carefully transplant to your medium. The seeds CAN EASILY BE DAMAGED, so be very careful, I use sterile tweezers to carry them, but you must not squeeze too hard, or you will kill your seedling. It’s safest to transplant before the seed shell falls off, using sterile gloves to pick it up using the opened shell, being very careful not to touch the root, or squeeze too much, cutting the root with it’s own sharp shell.
