If growing outdoors, till the soil well and amend it with organic nutrients to produce a happy, healthy plant. But, no matter what you do while growing indoors, stay away from old used soil or sterilize it before you plant seeds to prevent diseases.
The appropriate pot size can also help you control the height of your cannabis plants, usually, a 12L pot will allow your plant to develop to its maximum, an auto in a 7L pot will grow up to 70cm and in a 3L pot will grow around 40cm.
4. Choose the right medium
A way to check if the soil is dry is to use your index finger and stick it in the soil, if it comes out moist then the soil is still humid, although by doing this you won’t be able to know if the bottom is still wet so in order to get the timing right, lift the pots and check the weight.
Can you grow autoflowering cannabis in a greenhouse?
Depending on your experience, you can also germinate your seeds directly in the medium, just make sure you’re not overwatering it because you can end up drowning your seeds. As you can see in the video, germinating in the soil is easy and doesn’t require anything extra, just be careful and you’ll see a seedling coming out of the ground in a couple of days.
Growers rarely cultivate pure ruderalis strains outside of breeding operations as these varieties produce very little in regards to yield. However, by breeding successful photoperiod strains with ruderalis genetics, breeders can create autoflowers, and therefore faster, versions of legendary varieties.
Regardless of the schedule, the lighting demands of autoflower strains are easier to meet than those of their photoperiod counterparts.
FASTER LIFE CYCLE
A schedule of 12 hours on and 12 hours off occupies the other end of the spectrum. It’s the best option for growers looking to save money, but yields won’t be as impressive.
You can easily grow autos on balconies and in hidden locations in your garden. They’re also popular among guerrilla growers—cultivators that grow cannabis in hidden public or wild locations. This method helps to keep crops out of sight and hidden from thieves.
Autoflower strains have a long list of advantages over photoperiod varieties. Their short life cycle attracts growers seeking prompt gratification, and their hardy nature makes them suitable for beginner cultivators and veterans alike.
One advantage of this internal timeclock is that auto-flowering strains can be grown outdoor in a city environment where the ambient light at night may be too bright for photoperiod plants to be able to make buds. Autos don’t care if they’re exposed to light at night. This can also be used in warm climates to get plants to grow outside the normal growing season. For example, as long as it’s warm enough you could start a plant in April outside and it will be ready to harvest by July, which is much sooner than you’ll be able to harvest any photoperiod plant (all of which are ready to harvest in mid to late Fall).
Light Schedule is 20 on and 4 off (20-4). Used that light schedule for the whole grow. This is my first time growing. The plant ended up being just under 2 feet tall at harvest. Harvested on day 67 from seed.
However, one major difference is that many auto-flowering strains tend to have higher amounts of CBD in their buds than photoperiod strains (because Ruderalis plants are high-CBD). CBD is a cannabinoid that is known for having medical properties as well as reducing anxiety.
Conversely, Ruderalis plants don’t need any type of signal. Instead, Ruderalis plants start flowering when they reach 3-4 weeks of age no matter what’s going on with the sun or light schedules, and their buds are ready to harvest only a few months from seed.
How big will each plant get?
Since photoperiod plants can be forced to remain in the vegetative stage for as long as the grower wants, a grower can take advantage of a variety of plant training methods to shape/train the plant during the vegetative stage, including LST, topping, FIMing, main-lining, ScrOG, etc.
