germinating cannabis seeds in a propagator

Unfortunately, transplanting seedlings is far from an exact science; rather than following a strict calendar or schedule, it’s all about paying attention to your plant and knowing which cues to look out for.

Whenever you start feeding your plants, we recommend giving them half the recommended dose of fertiliser during the first week of feeding. This gives the plants time to adjust to their new diet.

Finally, to minimise the chance of a Pythium, Botrytis, or Fusarium infestation even further, be sure to always use new soil or sterilise your soil by baking it in the oven until it reaches a temperature of 85°C.

KNOW WHEN AND HOW TO TRANSPLANT YOUR SEEDLINGS

Carefully place your cannabis seeds between a few moist pieces of paper towel, and place it all in a plastic container with a lid. Keep the container in a warm, dark place (temperatures between 20–25°C are ideal). Leave a slight crack in the lid to allow for some fresh air exchange.

No matter if you have a large cannabis growing operation or are an amateur just beginning your first seedlings, making use of propagators is a great way to control growing conditions and speed up your seed germination. A propagator allows you to take full control of your growing conditions, allowing you to germinate and grow your seeds and seedlings in a safe, moist and warm environment to give them an optimum chance of becoming healthy and high yielding plants.

Any propagators can be used to grow cannabis, as they come standardised with a thermometer and built in LED Lights. They can either be powered by batteries or electricity, and allow you to control the environment within the container. Seedlings can sprout up to 30% faster when you use a propagator and the environment is much safer as you can fully control the heat and moisture content, and you cannabis seeds will also be less susceptible to damage by insects or disease. Seedlings can be kept in the propagators until they sprout their first set of leaves. This ensures that they will get a good start and grow into healthy, high yielding plants.

Using a cannabis propagator

Small, fragile, and in desperate need of a helping hand, there are several ways you can germinate your cannabis seeds. All methods have varying degrees of success, with both advantages and disadvantages. It is important to note that even with advanced growing expertise and top-of-the-line equipment, you may still end up with a few failed seeds. This is a natural part of dealing with a living organism. At Royal Queen seeds, we only sell feminized cannabis seeds, so there is no need to worry about removing male plants.

Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).

WHAT TO LOOK OUT FOR IN CANNABIS SEEDS

To avoid disappointment, seeds that have a darker colouration stand a better chance of germinating, while pale green or white seeds are likely to fail. Even if dark seeds look slightly damaged, they should be planted anyway. There is a good chance they will still germinate, even if the outer shell is somewhat crushed.

Before you can be met with bountiful hauls of dank buds, there are several stages of cannabis growing that take precedence. Unless you can successfully germinate cannabis seeds, you won’t have a plant to harvest. Give your seeds the best possible start in life by reading our definitive guide to germination.

Place one sheet of damp kitchen towel on a flat surface. Space your seeds a few centimetres apart before placing the second piece of kitchen towel over the top. You need to ensure both pieces are damp, not wet. Once again, when the white root tips reach 2–3mm, move the seeds (carefully) to soil pots. Use the same guidance found above for planting techniques.
