growing marijuana vegetative stage

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.

Marijuana light cycle: 16 hours a day

Seed germination

There are a number of changes to consider once plants go from the vegetative stage to the flowering stage:

The Spring Equinox is a good reminder that it’s time to kick off the outdoor growing process and start germinating your seeds.

Notes on marijuana growth phases

At this stage, the plant is vulnerable to disease and mold. Keep its environment clean and monitor excess moisture. Be sure to give it plenty of light.

Once your seed has germinated, or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.

These cannabis plants were vegetated for about 8 weeks before being flipped to the flowering stage. Although they were grown in the exact same conditions from seed to harvest, their final heights are remarkably different because their strains had vastly different genetics. The smaller plant produced 6.6 ounces, while the big plant produced 9.3 ounces. Strain can make a big difference! Learn about growing different strains together.

If growing in soil without added nutrients:

If you’re worried about the temperature dropping below 70°F (20°C), then 24 hours of lights a day might be better, because it can help keep your plants warm.

How Long Should the Vegetative Stage Last?

There will always be growers who feel that cannabis plants need some time with the light off (a dark period) in order to have optimal growth, while others believe that the extra hours of light are better since they give your plants slightly faster growth in the vegetative stage.

The size your plant achieves in the vegetative stage has a very large effect on your final yields since bigger plants produce more bud sites than smaller plants. However, you need enough light to cover all the bud sites or they will never develop properly. Light is like food for bud growth!

Provide light – Use your vegetative grow light as directed. Simply turn grow lights on and keep at the recommended distance from the top of your plants. Outdoors plants will continue vegetating until days start growing short. Indoors plants will stay in the vegetative stage as long as they’re getting 18+ hours of light a day

Seedlings may need less water at a time until they are growing vigorously. Especially if young plants are in a big container, avoid giving a lot of water at a time until the plants starts growing faster. Once plant is growing new leaves and stems regularly, start watering using the techniques explained below. How to water cannabis properly…

Question: How do I know when the marijuana vegetative stage is over?

Growing marijuana vegetative stage

Marijuana legalization is spreading. Medicinal marijuana use is now legal in over half of states, allowing patients access to the herb once they have a recommendation from a licensed physician. However, it’s no secret that weed is expensive.

1. Germination: Between 24-Hours and 2 Weeks

At this point, you should keep the temperature somewhere between 68 and 77˚F, with the humidity at around 50%. You can stop giving the plant nitrogen now, but up the intake of potassium and phosphorus.

5. When to Harvest Marijuana

If you’re planning on cultivating your own weed continuously, you’re going to need some more seeds. We mentioned removing the males from your cannabis crop, and this means that your females won’t be pollinated and won’t be producing seeds. As a result, it’s unlikely that you will have your own seeds to work with.
