In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.
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.
Is the seed viable?
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”
WATER: Like all living things cannabis needs water to grow, thrive and carry out its biological functions. If you live somewhere with regular rainfall your outdoor crop may get all it needs from nature alone. Large cannabis plants are notoriously thirsty. If you are going big then you will certainly need to supplement water between rains.
Growing your own cannabis is a fun and inexpensive way to put high-quality buds in your jar. Marijuana is a hardy plant that can grow in a wide range of climates, in greenhouses or indoors all year round.
Step 2: Cannabis Fundamentals
Outdoors you need to pick your time. Know your particular climate well. Have a sun cycle app or chart to make sure you get your timing right. Too early and you risk your plants going into flower immediately, then re-vegging when the daylight increases. This is unwanted. Your flowers will not form properly when blooming begins. Too late and you will have small plants with fewer flower sites.
Growing cannabis is an organic process without strict sets of rules. It is not a linear system to learn, but an art to be mastered. There are a number of equally effective methods for germinating cannabis. Over time you will find the one that works best for you.
JIFFIES, PLUGS AND ROCK WOOL STARTERS: Easy to maintain as you can have fifty seeds germinating in a very small space. Once the seedlings are established they can be put in their final position without damaging roots.
