However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.

This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.

Climate considerations

Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.

For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.

Step 4

Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.

When planning a vegetable bed, you may decide to start from seeds directly in the garden. There are benefits to this, and it eliminates the step of moving transplants from indoors. One issue comes up though – how can you identify seedlings from little veggie sprouts?

Knowing how to tell seedlings from weeds is a great skill to have as a gardener. You’ll find plenty of resources online to help you make this identification. These include pictures of vegetable seedlings as well as those of common weeds, allowing you to simply check what you have and only pull weed seedlings. Until you get to know your seedlings better, here are some tricks and tips that will help make the task easier:

Importance of Sprout Identification

Make the wrong identification and you’ll pluck what you think is a weed only to find you pulled out your vegetable seedlings. When plants are at the seedling stage, they look quite different from their mature stage. To avoid ruining your beds before you have barely started, you need to get good at identifying seedlings.

How can you identify seedlings and not mistake them for weeds? This is tricky, even for the most seasoned gardeners. If you don’t know the difference between a weed and a radish sprout, you could destroy your vegetable bed before you have a chance at a harvest. You can learn to identify veggie seedlings, but there are some other tricks that can help as well.

Is it a Seedling or a Weed?

Sow your seeds in a very straight row and use markers at the beginning and end of the row so you know where seedlings should be when they start to grow.

Watching a cannabis seed germinate can be a lot like waiting for water to boil — it takes time (typically a couple of weeks). The seeds will eventually crack open and a white root will shoot out of the cracked cannabis seed shell. The white root is often referred to as the taproot. Once your sprouting seed has a strong taproot (an inch or so) it is ready to be transplanted.

Viable cannabis seeds tend to have a darker color with shades of grey, black, and/or brown. A really good cannabis seed will typically have a ‘tiger stripe’ across it. Another way to tell if a cannabis seed is viable is by touching it (make sure to wear gloves when handling cannabis seeds). A quality seed should withstand a bit of a pinch. If the seed collapses under a little pressure, then it wasn’t viable.

Various products such as “rapid rooters” can be incorporated into germination strategies, however, they are not as cost-effective as the paper towel method.

If you consume cannabis long enough, chances are you will come across a seed in your cannabis flower. Whether you want to try to germinate the seed immediately, or save it for down the road, it is important that you know if the cannabis seed is viable to be germinated or not.

When Is The Seed Ready To Be Transplanted?

If the temperature of the room is too cold (below 55 degrees Fahrenheit), consider using a heating mat, which can be found at most department stores in the gardening section. The success rate of the paper towel method is high as long as the cultivator keeps a close eye on the process until the germinated seed is ready to be transplanted into potting soil, peat pellets, or a different growing medium.

Some cannabis cultivators prefer to start with cannabis clones versus marijuana seeds. Each route has its own advantages, however, seeds are typically easier to acquire than clones. While clones and seeds will both do the trick, seeds also seem to be a more popular route in many areas.

Arguably the easiest and most cost-effective way to germinate a cannabis seed is to place it between wet paper towels (often referred to as “the paper towel germination method”). Add a bit of water to the paper towels and squeeze out the excess water.

How Do You Know If A Cannabis Seed Is Viable?

Cultivating cannabis from a seed is not as easy as many beginner growers might think. Various factors are involved which will ultimately determine if the cultivator is successful and has a large harvest, or if they fail and have to go back to the drawing board. Learning how to germinate cannabis seeds is the first step to becoming a cultivator.

Germinating marijuana seeds is not difficult, although it does take attention to detail and the right environment. Successful germination takes the right amount of moisture, the right temperature, and a decent amount of light (sunlight or artificial light from low-intensity grow lights).
