how to choose seeds for growing weed

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.

Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.

If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.

As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.

Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.

Think about the effects that you would like your cannabis to have when consumed. There are two main categories of cannabis – indica and sativa. Sativas produce an energetic, creative feeling in users. Indicas reduce anxiety and inflammation but often leaves users feeling tired.

Cannabis sativa plants will grow tall and thin. They take longer to mature than indica plants. Sativa plants tend to have bigger yields than indica plants. Indica plants are shorter and more bush-shaped and tend to produce fewer buds than sativa plants.

Male vs. Female: Does it Matter?

Seeds are only produced by female cannabis plants after a male plant pollinates them. To grow your own seeds you will need the female plants that produce the seeds, as well as a male plant to fertilize the female plants. It’s as simple as placing the male plant near the female plant you want to fertilize. Seeds will appear in about 4-6 weeks. This can be a complicated process, with a lot of uncertainty, so many people choose to purchase feminized seeds instead.

Don’t get overwhelmed. There are a lot of options when it comes how to choose cannabis seeds! The best way to learn is just to get started.

Another thing to consider, especially if you are a novice grower, is that indicas take less time to mature than sativas. Indicas are considered a hardier plant that can withstand more stress so they are more forgiving to novice growers who tend to make a few mistakes on their trial run.

Not all cannabis strains are equally suited to all climate zones. If you live in Northern Europe and you’re growing outdoors, you will want cannabis strains that are resilient to cold and rain, and those that finish their grow cycle quickly. Luckily, many of the strains bred to thrive in colder climates are naturally fast-growing and flower quickly. This way, you can harvest primo bud before mould and rot have the chance to spoil your harvest.

When growing cannabis, the type of seed you choose is also of great importance. There are three types of seeds to select from: regular seeds, feminized photoperiod seeds, and autoflowering seeds.

Cannabis strains can be easier or more difficult to grow depending on several factors. We already mentioned the photoperiod/autoflowering divide, but there are other variables too. Some strains are bred to be more robust, with better natural resistance against common pests, mould, and diseases. They can be less picky when it comes to nutrients and watering, and can tolerate grower error better than others. So if you’re new to growing cannabis, it can be best to choose a strain known for being fairly low-maintenance.


The first thing you will likely want to look at when choosing a strain is what effect it has. For this, it helps to have a grasp on the three main types of cannabis seeds: indicas, sativas, and hybrids. Here is a quick rundown on their different effects and growth profiles. Keep in mind that most modern cultivars are some sort of hybrid, combining the effects of various strains in different ratios.

Indicas are primarily enjoyed at night; they induce a pleasant, physically relaxing effect that is best described in one word: stoned. Strong indicas can be so relaxing indeed that they catalyse what’s known as “couch-lock”, a state of near-immobility as a result of the aforementioned physical sedation.

Feminized cannabis seeds do away with the hassles of male plants as they sprout only females. Since females are the ones that produce resin-rich buds, this is the choice most growers opt for. If you grow indoors, you control the growing stages of feminized photoperiod cannabis plants with a timer for your grow light.

When it comes to selecting the right seeds for you, there are various factors to keep in mind to help set you up for success. It’s all about what you need, what you want, and what you have (space, energy, etc.).
