ACTIVATING SEEDS IN WATER
Put your seeds in a glass of spring water at room temperature for 24 hours in a dark, warm place like a cupboard.
One reason people experience germination problems is insufficient heat. Remember that in nature cannabis seeds are shed in fall and wait all winter before germinating in the Spring. Warm temperatures activate germination.
To improve germination rates, place the glass on a heat mat with a towel between the glass and the heat mat, and a towel over the glass.
After 24 hours, proceed to the paper towel technique.
TIP: Soaking seeds in a kelp extract solution improves both speed of germination and germination success rates due to the gibberellins hormones in kelp which regulate seed germination.
PAPER TOWEL TECHNIQUE
Wet a paper towel with a garden sprayer. The paper towel should be very evenly moist but not drenched.
Pluck your seeds out of the cup of water using your fingers or a strainer. If you use your fingers be careful not to damage the taproot if one has already started to emerge.
Put the seeds on one side of the paper towel and then fold the damp paper towel over the seeds.
Place the paper towel in a baggie and leave the mouth of the bag open. This step helps prevent paper towels from drying out.
Place the baggies on a towel with a heat mat under the towel.
Check on the seeds every 24 hours. On average it takes 48-72 hours before the taproots emerge from the seeds. Ensure the paper towel remains evenly moist. Do not let the paper towels dry out.
When the taproot emerges a few centimetres it is ready for planting and can be moved to the growing media. We recommend not letting the taproots get too long before transplanting to soil because the taproots are delicate and it is easier to damage a long taproot than a stubby one.
TRANSPLANTING SPROUTED SEEDS TO GROW MEDIA
Get any type of small container that will allow drainage. A cheap solution is beer cups with holes drilled in the bottom.
Fill container with grow media. Do not use soil that has been infused with nutrients. Soil intended for adult plants contains fertilizer that can harm small seeds.
Water the media so it is evenly moist. If you overwater and turn the soil into wet mud the seeds might become too water logged and rot.
Poke a hole in the grow media for the seed to go into. The seed should not be buried more than 1 cm deep.
Place the seed in the hole with your fingers. Cover it with grow media and add more water using a garden sprayer pointed directly at the spot where the seed is buried.
Seeds don’t need fertilizer because they already contain enough nutrients to fuel germination. Once the seed sprouts and its first 2 baby leaves start to turn yellow it signals the internal resources of the seed are exhausted and it’s time to start fertilizing. At that point, you should start using water with 300 ppm nutrients.
Ramp nutrients up to 350-500 ppm as the seedling gets bigger.
pH balance water to 5.8.
The ideal temperature for seedlings is approximately room temperature (around 70-80ºF, 21-36º celsius).
A 50% or less ambient humidity is ideal. We do not suggest a humidity dome for seeds.
