Indoors

It's important to make sure plants aren't exposed to light at night during their dark period, even street lights or spotlights, as this can prevent cannabis plants from flowering properly.

Cannabis will stay in the vegetative stage as long as the plant gets short nights (less than 11-12 hours of darkness each day)

So indoor growers have a choice to flower their plants whenever they want… When is the best t ime to start flowering your cannabis indoors?

Harvest!

The vegetative stage is the growing stage of the plant. When in veg, cannabis plants grow bigger and taller, growing only stems and leaves. As a grower, you are able to control the size and shape of your plants in the vegetative stage using simple training methods.

Give 18-24 hours of light a day

Outdoor growers wait until their cannabis plants start naturally flowering on their own, usually after mid-summer when days start getting shorter than 12 hours.

If you live in a cold climate, you must also wait until after the last frost before putting your plants outside. Freezing temps will kill cannabis plants. Strain choice is very important. Some strains flower earlier than others. For outdoor growers in cold climates, it's important to make sure you grow a strain that is matched up with your local weather, so that plants are ready for harvest before temperatures drop.

The majority of cannabis plants are photoperiodic, this means they depend on a 12/12 light cycle to flower. It’s crucial you provide the correct light cycle so your cannabis plants start to flower, although depending on the strain this can change, autoflowering strains start the flowering stage automatically and don’t depend on light.

1. What Is The Light Cycle In Flowering Cannabis?

It can take a couple of weeks for your cannabis plants to enter the pre-flowering stage and show signs of maturity (pistils or pollen sacs if they’re regular seeds), but soon you’ll see beautiful buds forming.

Autoflowering Plants

12/12 is usually used for the flowering stage of photoperiodic plants, or for those growing both autos and photos in the same growing space.
