Marijuana light cycle: 12 hours a day
The weather will start to turn and the sun will begin descending in the sky as your plants fatten up with sweet, sticky buds. It might be tempting, but wait until around the Fall Equinox to start harvesting.
Be very careful to not overwater the plant in its seedling stage—its roots are so small, it doesn’t need much water to thrive.
If you buy a clone from a grower or breeder it will be a seedling, so you can skip the seed germination phase.
When your marijuana plant becomes a seedling, you’ll notice it developing more of the traditional cannabis fan leaves. As a sprout, the seed will initially produce leaves with only one ridged blade. Once new growth develops, the leaves will develop more blades (3, 5, 7, etc.). A mature cannabis plant will have between 5 or 7 blades per leaf, but some plants may have more.
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.
There are a number of changes to consider once plants go from the vegetative stage to the flowering stage:
No. Unless you live in an area with very mild winters and low rainfall, we don’t recommend growing cannabis outdoors during winter, as you’ll usually end up with sickly plants and/or poor harvests.
If your plants have started to flower, you’ll need to be even more careful. If you give them more light indoors than they’ve been getting outside, they may revert back into their vegetative cycle. This process is known as revegetation, and causes extreme stress for the plant.
LED aficionados face the prospect of running the heating virtually nonstop. Perhaps a combo of HID and LED is the smartest compromise in freezing conditions for the modern indoor cannabis grower.
Can You Grow Cannabis Outdoors In Winter?
Depending on the flowering time of the particular strain you’re growing, your plants could be harvest-ready either by mid-winter (if you germinated your seeds in fall) or mid-fall (if you germinated in summer).
We all know that cannabis grows best in areas with warm summers and plenty of sunshine. But, being such a versatile and hardy crop, you might be wondering whether it’s possible to grow cannabis in cold weather. Thankfully it is, but there are some key tips and tricks you’ll need to keep in mind.
There are 2 main concerns when it comes to growing cannabis in cold weather or winter. The first is shock to the plant’s root systems.
Mold is the second major concern when growing cannabis in cold weather, especially if there’s moisture in the air.
