It’s both exciting and a bit confusing when you begin to grow cannabis. If you’ve never been much of a gardener in the past (and even if you have!) you probably have quite a few questions. While it may be called “weed,” this isn’t like the weeds on a sidewalk that will flourish in any type of environment. You need to care for your plants properly in order for them to grow, and grow well.
One of the most important things to get right is the lighting. How much light does a weed plant need? Let’s dig deeper into that question right now!

How Much Light Does a Weed Plant Need?
Sorry to say it, but this question doesn’t have just one simple answer. You see, cannabis plants need different amounts of light during each growth stage. That being said, there are some general guidelines as to how much light they need in each stage.
Each stage needs specific light and nutrient conditions. The four stages of growth are:
Germination stage (3-10 days)
This stage is pretty simple. During this period, your cannabis seeds should be kept in a cool dark place, away from both direct sunlight and artificial light.
Seedling stage (2-3 weeks)
This is when the plants begin to develop leaves. Your cannabis plants should have 16 hours of artificial LED light per day during this stage. The remaining 8 hours should be total darkness. Seedlings benefit from lights that don’t produce a lot of heat and have a lower wattage.
Vegetative stage (3-16 weeks)
During this period, the cannabis plant grows stems and leaves. There are no buds quite yet. Right now, your plant should still have a lot of light, anywhere from 12 to 18 hours of it.
Flowering stage (8-11 weeks)
This is when flowers start to form, producing the resinous buds we all know and love so well. The duration of the flowering stage depends on the exact type of strain you’re cultivating. During this stage, the plant needs 12 hours of light and 12 hours of uninterrupted darkness. With this exact split, you are able to induce flowering.
