how to germinate marijuans seeds in rooters

7. Watch for the seeds to sprout and surface, making sure to lightly water every 2-3 days to prevent Rapid Rooters from drying out (5) .

Cannabis seeds and humans have a long history together, with the oldest known relationship dating back many centuries. In 2007, archaeologists found cannabis seeds in a Chinese tomb that was 2,700 years old. Although the seeds were ancient, they were preserved so well that they may have germinated.

Together, we can add to this multi-millennia relationship and play a part in the beautiful history of cannabis.
When growing from seed, you have control over every aspect of the product you produce. You can pick flavors and effects that you enjoy, making your strain selections unique and personal.

How To Germinate Cannabis Seeds

The warm water washes away growth-inhibiting hormones and moistens the seed at the cellular level, thus providing the optimal conditions for growth. In nature, most plants produce large amounts of seeds. And with luck, a small number will germinate and survive to grow up and reproduce themselves. As masters of the indoor growing environment, it is up to us to germinate and pass on desired genetic traits.

3. Put the shot glass in a dark place that has a stable temperature of around 70-80 degrees.

5. Soak the Rapid Rooters in plain, room temperature water (tap, filtered, or RO water is fine) (3).

When growing from seed, it’s essential to start with large, healthy, and mature seeds. Often, growers make the mistake of buying inferior seeds. This puts them at a disadvantage right from the start. At Greenpoint Seeds, we go through multiple steps to guarantee our customers get the best seeds on the market. We begin by using an airlift that sorts the seeds by weight. The airlift raises the lighter seeds out of the batch, leaving only the heaviest, most-mature seeds. Next, we use a sieve that sorts the seeds by size, discarding the smaller seeds so that only the largest remain. Finally, we do a visual inspection and remove any discolored seeds to ensure only the best cannabis seeds go into a Greenpoint Seeds Premium Collector’s Pack.

How to Water Seedlings in the Beginning

Supplies Needed


Water immediately in a small circle around your seedling. For most grow mediums and containers above 1 gallon, you can give 2 cups (500 ml) of water immediately without overloading your seedling. If the grow medium feels moist (for example coco that was recently re-hydrated), give 1 cup (250ml) of water this first watering.

If your growing medium takes longer than 3 days for the top inch to dry, it means the soil is staying wet too long, and plant roots aren’t getting enough oxygen. It also puts your plants at risk of getting fungus gnats . Try giving less water at a time until the plant is drinking more. It’s possible you may have a problem with drainage in your medium ( what is good soil? ) or there are no drainage holes so extra water can’t come out the bottom of the container. Always remove any runoff water instead of letting the plant sit in it.

They are under 2 23w CFL’s.

Also cut off a small piece of the plug and gently placed over the holes.

I placed them in small rapid rooter plugs (dunked them in 6.0ph water then rang them out) and put a small humidity dome over the top.

Okay so I placed my seeds in water until they sank, but I also turned on a heater on the containers to get them hot (no heating pad).. the water got pretty hot for about an hour. Could that have been bad for the seed first off/killed them.

The seeds cracked so I placed them in damp paper towel in an enclosed tupperware bin. The tails haven’t showed yet (could they be dead) It has been two days.

Rooters/plant plugs are awesome for cuttings, but for Cannabis seeds it only seems like a slight step up from paper towels to me.

2-3) inches. For this reason, and to prevent the media from drying out very quickly, it is recommended to start seeds in a container at least 3.5-4 inches deep. This way the tap root has sufficient room to stretch out from the outset. The seedlings also wont have to be handled so much. You can use Rooters to germ Cannabis seeds, but you’re going to want to transplant them into a larger container relatively soon after they sprout. Right after they sprout you should see a taproot hanging out of the plug, which isn’t really a good thing.
