When does a cannabis plant start budding?
I tend to set my timer to shine line from 8pm-8am. This gives me time to check on my plants at night when the lights first come on, and I can also check them quickly in the morning before I go to work. It also keeps things cooler since the lights go on at night.
So all strains of cannabis that respond to light in this way (where the light period effects what stage they're in) are called "Photoperiod dependent" strains.
So unless you're planning on breeding, it's important that most growers destroy male plants as soon as you notice them growing grape-like balls where their buds would normally be.
Unfortunately, about 50% of all regular (unfeminized) cannabis seeds are male (though this varies from strain to strain, and from environment to environment). Fortunately for small growers, you can purchase feminized (all-female) seeds so you don't have to worry about male plants if you don't want to. Learn more about buying seeds.
After 2-3 weeks of the 12-12 light schedule, most cannabis plants will show the first signs of their gender (they either are a female plant which starts growing buds, YAY! or they are a male plant which start growing balls/pollen sacs, NO!).
Photoperiod dependent strains vs. auto-flowering strains
This means that when growing outdoor you have to know the amount of light and darkness you will receive in the next couple of months so your plant develops the way you want to.
Not always giving them more light is going to result in faster or more development and you can harm or really stress your plant by doing this, making them turn into hermaphrodites or showing other heat stress symptoms.
As you may know, when growing indoors we are responsible for maintaining all the elements of the environment, in the beginning, it can be a little bit hard but when we get more experienced it can have various advantages.
2. Light Cycle For Vegetative Cannabis Outdoors
Like we said above, photoperiodic cannabis depends solely on the amount of light and darkness to start flowering, which can be tricky for new growers outdoors but when growing indoors, we are in full control of everything, including the light schedule.
