Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.

How weed clones work

CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.

Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.

Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.

Growing cannabis at home can be a fun project and a nice way to have your own cannabis plants on hand. You may want to grow cannabis indoors due to inclement weather in your area or due to a lack of green space in your yard. Start by germinating the seeds. Then, plant the seeds in soil or in a starter cube. Once the seeds have been planted, care for them properly so they grow and thrive.

To plant cannabis seeds indoors, first soak the seeds in lukewarm tap water for 12 hours. Discard any seeds that float to the top. Then, place the seeds on a damp paper towel on a plate with 1 inch (2.5 cm) of space between each seed. Cover the seeds with another damp paper towel. Keep the seeds in a spot that remains between 70-80°F (21-27°C), and spray the paper towels with water whenever they start to dry out. The seeds will sprout in 2-3 days. When they do, fill pots or a growing tray 3/4 of the way with loose potting soil that has a pH between 5.8 and 6.3. Press the soil down lightly, leaving some air in it. Then, use a pencil to poke 1 inch (2.5 cm) holes in the soil. Place the sprouted seeds vertically in the holes and fill the holes with potting soil. Water the soil thoroughly and place the pots or tray in a spot that’s always 75°F (24°C) or warmer. Set up a grow light over the seeds and leave it on at all times. Water the seeds every day so the soil doesn’t dry out. The seedlings will emerge in 2-4 weeks. To learn how to use cool white grow lights to help your cannabis seeds grow, keep reading!

It is advised to replant earlier to avoid having a “root-bound” plant. This happens when the plant is left for too long in the starter container and the roots have grown too large for the small space. It will asphyxiate the plant and it might die. If you notice the plant absorbing water within the day, it might be time to transfer it.

During the germination state, you can use lamps to provide warmth until the first seedlings appear out of the soil. This can happen within 3-7 days after planting the seeds. These seeds have more activity at night, so keep the lamps lit for 24 hours to help the seeds grow out of the soil.

This method is a lazy grower’s technique. It is going straight-up planting the seeds directly in the soil or some soil substitute. This can be risky for amateur growers who are unaware of the importance of pH soil levels, humidity and nutrient requirements. However, some people have successfully grown healthy marijuana plants by planting the seeds jokingly.

Wait Patiently

Transferring germinated weed seeds is a process that can be challenging for newbie growers. There is the tenement rule of not touching the taproot for they are very fragile.

But before proceeding, make sure that you have older, unchecked seeds or those that are partially dried out. Newer and freshers seeds do not require sensitive germination and they can be planted directly into a growing medium.

Replanting or transferring the plants can be a stressful phase for the gardener and the plant. To make things slightly easier, here are some points to remember:

Some people who are new at planting marijuana seeds tend to be too eager or too keen to see how the seeds are doing. In their eagerness, they miss out or overdo something that can be harmful to the seedlings. So here are some of the things to avoid to ensure that your weed seeds do not die.
