Seed germination length: 3-10 days
Vegetative plants appreciate healthy soil with nutrients. Feed them with a higher level of nitrogen at this stage.
Notes on marijuana growth phases
Marijuana light cycle: 16 hours a day
The growth stages of marijuana can be broken down into four primary stages from seed to harvest:
As the sun reaches up high in the sky, your cannabis will want to as well. Make sure all of your plants are outside by the Summer Solstice.
Use these tips to speed up your grow at any point between germination and harvest. Learn practical ways to make things go faster in either veg or flowering, inside or out. Don’t be surprised if one of the tricks for outdoor growers is a bit shocking. We weren’t expecting it either!
No matter the reason, there are proven ways to rush things along, whether you’re growing inside or out. Still, you might have to compromise yield and potency in exchange for speed. Let’s take a look at what you can do to grow cannabis as fast as possible.
TIPS FOR FASTER INDOOR GROWS
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.
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.
When growing cannabis indoors from ordinary seeds, the grower has to decide when to switch the plants from the vegetative phase to flowering. This is usually done by altering the lighting schedule. Reducing the total hours of daylight stimulates the plants to produce buds and will start the flower stage. This is usually about two to three months after sowing, depending on the variety.
Santa Maria, Gorilla Glue and White Widow x Northern Lights are among the many cannabis varieties that flower quickly. All of these strains have a flowering phase of six to eight weeks, shaving around a month off the entire process.
1. Start the flowering phase as soon as possible
Planting clones rather than germinating seeds yourself will save a couple of weeks. Clones are plug plants that are sold with an established root system, so all you have to do is pop them into the soil. The downside is that clones are genetically weaker and less likely to survive than plants grown from seeds, as they are more likely to succumb to pests, mold and disease.
It may sound obvious, but one of the easiest ways to reach harvest quickly is to choose seeds with short flowering times. Always buy seeds from reputable and established sellers who will display growing and flowering times on their websites. The aforementioned Northern Lights feature a two-month flowering phase, while others, such as Sour Diesel need to flower for more than 2,5 months. Strains with longer flowering times generally tend to perform better outdoors because they receive more sunshine. However, varieties with short flowering phases often produce cannabis of equally good quality.
However, it is technically possible to make your seedlings produce buds pretty much as soon as they sprout and bypass the vegetative stage altogether. Northern Lights is a variety with a flowering time that lasts for two months. If seedlings produce flowers as soon as they germinate, it is theoretically possible to harvest in as little as three months – two months quicker than the average grow time of five months. However, the yield will always be much less simply because the seedling will not have had enough time to grow stems needed to produce buds.
