Regardless of which is best for plant health, it’s a proven fact that marijuana plants given a full 24 hours of light a day will grow at least a little faster during the vegetative stage (however, you may consider back down to 18/6 if your plant is sick to help it recover from problems faster).
Every different strain has pros and cons, but if time is a factor for you, pay close attention to the length of the flowering stage when deciding which strain to grow. The majority of seed banks list the length of the flowering period as part of their stats for each strain.
I know this sounds like it doesn’t need to be listed, but it’s a more important job than people think. Every time your plants get sick, it slows down their growth while they try to recover. Every problem your plant runs into can add days or even weeks on to your total grow time.
You can get a marijuana plant to start flowering by ensuring that it gets 12 hours of uninterrupted darkness each night, often referred to as the 12-12 light schedule.
Some growers believe it’s better to give marijuana plants 18 hours of light a day max, with a 6 hour dark period during the vegetative stage.
- nutrient problems or a pest infestation can dramatically slow down growth, especially for young plants
- heat stress or light burn can not only slow down growth in the vegetative stage, they can prevent buds from maturing properly in the flowering stage
- accidentally re-vegging your budding plants will stop buds from maturing
The more you tend to and baby your plants, the better they will grow, and the faster you will be able to harvest.
Yet growing indoors gives you the ultimate control over how big your plants get, how long to keep them in the vegetative stage, and exactly when they start flowering amongst other things. You also have a lot more control over how much bud you’ll end up yielding.
So, how long does it actually take to grow marijuana?
