Wet thoroughly enough perlite to cover the bottom
of the propagator approximately 2cm deep. Plug the propagator, or heat pad, into the thermostat controller, plug the controller into the power and set for 23 C. Place the heat-sensing probe into the wet perlite just beneath where the seedlings roots will be. If using a heating pad lay it out beneath the propagator tray.
With a thin pointed object such as a pencil, make a small hole in the center of each jiffy-pot about twice the depth that the seed is long (This varies with strain, but 5-8mm deep should be sufficient. Often the mistake is made of planting seeds too deeply, and they rot before they see the light of day. To ensure this doesn’t happen, never sow seeds deeper than 1cm). If sowing more than one variety remember to prepare identification labels in advance and label them as you go to prevent mix-ups.
Some people advise keeping young seedlings under fluorescent lighting for a while but this doesn’t provide them with the correct spectrum for photosynthesis. It is best in our opinion to place seedlings directly under low wattage H.P.S lamps, 150/250/ or 400 watts, at a good distance away.
Once the plants are a few days growing they need to be moved closer to the lamps in order to prevent stretching. Move them as close to the lamp as the tops of many plants would be comfortable. (30-60cm depending on the lamp size.)
Seeds need to be damp, not wet for germination. Excess water prevents oxygen from getting to the seed. Poorly drained soils may also cause soil fungus diseases. The condition of wet soils may be improved by adding perlite, which will aerate your soil. Make sure any trays or pots you use have holes in the bottom to let the excess water drain.
(This can also be done with the help of a coarse sieve if you like.)
The ideal temperature marijuana seed germination is 70°-78°, so try to keep the jiffy pellets in an environment that can accommodate that.
It is very important to only put one marijuana seed per jiffy pellet.
You should NOT soak the jiffy pellets. They will become too wet and if you squeeze them out they can become unstable.
They come dry and compressed. We will need to add water to them so they expand and become usable for planting.
My favorite way to germinate marijuana seeds is with jiffy pellets. I currently have a 100% germination rate using jiffy pellets!
It will take the seeds a few days to germinate. It is very important to make sure that they jiffy pellets do not dry out during this time.
Anywhere from 2-8 days later, you will see your marijuana seeds begin to pop their heads out of the jiffy pellets. This will not happen to all your seeds at one time, so be patient and do not mess with the ones that need a little extra time.
After one week under the LED grow lights the plants are looking bigger than ever !
Once planted you need to leave them inside the container at room temperature for up to eight days. The germination process takes anywhere from 2 – 8 days to get the seedlings to sprout. After the first 24 hours, the pellets seemed very dry. I then proceeded to add a little water to each to keep them moist.
I bought a pack of 36 jiffy pellets as the 12 pack was out of stock. When starting this you need to choose how many plants you want. I wanted to grow 4 plants.
Step 5: Transplant the pellets into your pots
After discovering jiffy pellets I quickly decided this was the route I’d take in starting my first indoor cannabis grow.
The first problem I faced was how to germinate the seeds.. what does germinate even mean?
Furthermore, I cut around the mesh so it was just the jiffy pellet by itself. I dug a small hold in the middle of my Vivosun 3 gallon fabric woven pots These pots allow oxygen to flow through the walls and allow the plant to grow to the maximum potential. I then transported the pellets into the holes I dug in the middle of the pots.
In conclusion, for the first time ever growing indoors, I couldn’t have thought of a more easy process.
