marijuana how long for seeds to grow

Cannabis plants will first give you an indication of their sex in the early phase of bloom. Typically within the first two weeks of flowering females will develop pistils or “hairs” to confirm their femininity.

One of the best ways to truly tell if your flowers are ready for harvest is by getting up close and personal with a magnifying device. This visual advantage will enable you to detect minor changes that wouldn’t be noticeable to the naked eye. Some growers choose to use a jeweler’s loupe, which is essentially a pocket-sized magnifying glass encased in a piece of metal. Others choose to use devices such as digital microscopes, which provide greater detail.

STAGE 1: GERMINATION — 1–7 DAYS

Now that harvesting and trimming are complete, it’s time to cure your flowers. Curing is an essential process that removes the last of the residual water from the buds, minimising the chance of mould and greatly prolonging shelf life. Curing also enhances the taste and quality of the smoke, making for a smooth and potent experience.

Vegetative growth is normally associated with a transplant at some point as plants outgrow the starter medium be it a Rockwool block or paper cup filled with soil or coco. Continued development of the root zone and robust branching are the top priorities for the grower. High RH of 50% is ideal and cooler temps 20-24°C can promote more females if growing regular seeds.

This is the stage to pot up photoperiod plants into final containers, at least a couple weeks before switching to bloom or prior to Summer outdoors.

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.

GERMINATION TEMPERATURE PLAYS A CRUCIAL ROLE

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).

Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.

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.
