It is important to germinate your Black Jack seeds carefully if you want to have a healthy harvest from day one. Although there are several methods to germinate our Feminized cannabis seeds, from Marifinder we recommend our customers to follow our easy and simple technique.

Before removing our Black Jack seeds from their packaging, remember that cannabis seeds are alive and delicate. The PH of our hands full of bacteria can easily infect them and ruin our germination.

Set Up Your Germination Station: Begin by moistening two paper towels with room temperature water. Lay one paper towel on a plate and spread the seeds on it, spacing them about 2 cm apart.

Place the second paper towel on top of the seeds, and make sure to remove any excess water from the plate. Cover the setup with another opaque plate and store it in a warm, dark location.

Monitoring: Make sure paper towels are still moist by checking every 4-6 hours and spraying room temperature water. Typically, germination should occur within 24 to 120 hours.

Once the seeds have sprouted tap roots, plant them with the roots facing down and cover with about 2 cm of soil. Remember to water the soil regularly by spraying to keep it moist. It may take up to two weeks for the plants to start growing.

Ideal Conditions: Maintain a consistent temperature of 70-90ºF in the germination area. Use purified room temperature bottled water with a pH level between 5.5 and 7.

Keep the seeds away from light, allowing exposure for less than 1 minute before and during germination. Avoid touching the seeds or applying pressure to them.

Record Keeping: To qualify for the three month germination guarantee, it is necessary to follow all the steps outlined in our germination guidelines.

Please do not use alternative germination methods, such as using a water bottle or planting directly into soil. Document the germination process through photography or video, as it will be requested when assessing claims for replacement products.
