Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.
The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flowering.
Take meticulous notes on when and how you perform each step, as well as what the weather is like. Other notes can include how much water you give plants, at what intervals, and how much nutrients you give them. Pictures will also give you a better sense of how your plants look along the way.
Marijuana light cycle: indoor—16 hours a day; outdoor—at least 6 hours of direct sunlight (“full sun”), plus several hours indirect sunlight
Even if growing outdoors, a lot of growers will start their seeds inside under an artificial light to help them through this delicate stage of marijuana growth.
Be sure to keep a grow journal to track the progress of your plants. Looking back on your notes will help you learn from mistakes and maximize the quality and quantity of your buds.
If you buy a clone from a grower or breeder it will be a seedling, so you can skip the seed germination phase.

Of course, how much sun your plants are getting determines how much water they should get as well. If they are getting tons of direct sunlight and the weather is quite warm, you’re probably going to water them more frequently. However, it’s important not to overwater marijuana plants, as that can lead to problems with mildew or mold development.
The size of your plants is going to make a difference in when you decide to start. This has to do not only with the strain you choose (and therefore the time it takes for that particular strain to go from seedling to flowering ) but also how large you want your plants to be.
How much sunlight is ideal for growing Marijuana plants outdoors?
ive been wondering the same thing. only answer everyone agrees upon is after the last frost.
You could build a coldframe and keep some lights above to keep the light cycle correct. Cheap pvc coldframes would be an affordable idea.
Seeds your good to go were at a litte over 13hours of sunlight in California atm. As for clones probly best to wait tell your closer to 14 hours of day light
