Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.
Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.
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.
Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.
Additionally, every long-time grower will tell you that clones degrade over time.
As the name suggests, autoflowering marijuana strains flower automatically rather than waiting for a specific light cycle. These plants produce buds when they are ready, which means there is no reason to mess with your lighting.
It is relatively easy to buy autoflowering seeds online. There is an increasing number of reputable websites that sell them. Alternatively, you can find them in a local dispensary, but purchasing the best autoflower seeds is a challenge at first.
Your Exclusive Autoflower Grow Guide
While varieties of autoflowering strains are getting bigger, you can still find versions that grow to about 40-50cm. Consequently, you can plant them in a closet, tent, or even on a balcony! You could also hide such a plant in a remote field if the grass is tall enough! Also, autos don’t require a ‘support system’ to hold up long branches that could bend or break as the buds get larger.
24-hour lighting will result in fast initial growth. However, it usually slows down after a few weeks because the plant is without adequate rest. The 18/6 schedule offers a delicate balance of plenty of light with ample rest. You also save money on your energy bill! For instance, in one month, using an 18/6 schedule against a 24/0 schedule saves you 180 hours’ worth of light!
The autoflowering phenomenon has only gained traction in recent years. Strains of this nature include Cannabis ruderalis genetics, a species of marijuana first described by D. E. Janischewsky, a Russian botanist, in 1924. When you cross ruderalis genetics with indica or sativa varieties, you get plants that grow and flower without intervention.
That said, you shouldn’t need very large pots for your autos as they won’t usually get very tall.
You should nevertheless choose a pot large enough so the plant doesn’t get root-bound, but instead has plenty of space to grow.
60–65 days from planting your seeds. Since many autoflowers won’t get taller than 50–70cm, they are ideal for growing indoors, where space is often limited.
TIP 3: USE A ROOT STIMULANT
The sea of green (SOG) method is really just a fancy term for growing a lot of smaller plants in your grow room for bigger yields. Autoflowers are ideal for growing in a SOG as they are already smaller by nature.
Then again, if you happen to be a medicinal cannabis user, or for some other reason choose not to get high, a low-THC, high-CBD strain like the excellent Solomatic CBD can be a good choice.
Autoflowers don’t have all the time in the world to grow. Right after sprouting, your plant will need to spend a good amount of time establishing a healthy root system. When you administer a root stimulant immediately after placing your seed in the pot, this will support your plant in this crucial process. But don’t go overboard as your seedling will be very sensitive to overfeeding. Use only the minimum recommended dose of root stimulant.
