Harvesting early outside is a little tricky. The obvious answer is to use autoflowering strains—and this does work. Depending on your weather, you may be able to harvest at least three times each growing season. Outdoor growers can also make photoperiod strains mature a little faster. Here are two things to try.
Starving a plant that wants to bloom for 9–10 weeks to force an early harvest can have a negative impact on yield. If you’re going to try this method, choose a cannabis seed with a naturally short finish time like Honey Cream. This is a high-yielding indica that only needs 6–7 weeks to complete its flowering cycle.
For those who prefer autoflowering hybrids, Northern Light Auto is a great choice. The original was already fast, but this improved version can go from germination to harvest in 10 weeks or less without any extra measures. Royal Cheese is a photoperiod strain, but this European favourite only needs about 6 weeks of 12/12 lighting to reach full maturity. Medical marijuana patients who are on a tight schedule should take a look at Medical Mass. This variety only needs 7 weeks of bloom to yield up to 550g/m² of CBD-enriched flowers.
TIPS FOR FASTER OUTDOOR GROWS
As a general rule, autoflowering cannabis will mature at a faster rate than photoperiod strains because they contain a percentage of ruderalis genetics. Ruderalis evolved naturally in cold places like Siberia where the summers are very short. They had to develop the ability to produce flowers and seeds quickly to ensure the survival of the species.
Sick plants need time to recover, so every time you overfeed, underfeed, or feed the wrong thing, you’re stretching the time until harvest. If you’re using nutrients designed for cannabis, they should come with instructions that tell you how much of what to use, and when to use it. Follow the directions, but keep the mix on the light side until you know if your plants are nutrient-sensitive.
If you want to use this method, you can start with either clones or seeds, but you’ll need to grow a lot of them in sea of green (SOG) fashion if you want enough herb to hold you over to your next harvest. Most plants will be dwarf-sized and only yield 28g or less each.
Growing indoors is almost always faster than growing outdoors, mostly because you can control the lighting. You can tweak a few other things in the name of speed too.
Many factors will affect the total time, but the average grow takes 3-4 months. Learn more about the marijuana growth timeline.
The more you tend to and baby your plants, the better they will grow, and the faster you will be able to harvest.
1.) Fewer Hours of Light Each Day in Flowering Stage
Give plants only 10 or 11 hours of light a day to get buds to mature faster
If you're serious about getting yields as quickly as possible, then these tactics will get you there the right way! Let's get to it!
Some strains are 'auto-flowering' and go through their whole life cycle regardless of light cycle or anything you can control. These strains tend to be ready to harvest in only 2-3 months from seed (though you should definitely expect smaller plants with relatively small yields when choosing an auto-flowering strain).
