Growing weed indoors with sunlight

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.

In the wild, as the days get shorter and nights grow longer, a marijuana plant "realizes" that winter is coming and will start budding/flowering. It "knows" it's approaching the end of its life cycle so it frantically starts making buds in time before winter.

If you don't understand light periods, your plant may never start making buds! The light schedule experienced by your plant will actually change its life stage. Learn more…

When growing marijuana outdoors, a grower doesn't need to do anything to induce flowering because the sun will take care of things on its own. It's just important to make sure that there are no lights shining on your plants during their night period (which will disrupt their dark cyle).

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.

However, when growing weed indoors, a marijuana gardener will have to fool their plants into "thinking" winter is coming to induce flowering and kickstart the creation of buds.

Photoperiod dependent strains vs. auto-flowering strains

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.

For an indoor grower, when a plant is about half the final size you want it to be, you should change it over to the "Flowering" stage. This is the stage when your plant starts growing buds.

Many hobbyist growers elect to use grow tents, closets, or other enclosed spaces when growing cannabis indoors, often outfitting these spaces with lights and even humidity and temperature control systems. Depending on your level of interest and enthusiasm, these systems can cost anywhere from hundreds to thousands of dollars.

I am a first time grower, anxiously awaiting my seeds that are en route. I don’t have a lot of options to be honest, other than to grow indoors under natural light. I have a main window that gives good strong direct sunlight for approx 6-10 hours a day give or take on the weather. I plan to grow ONE seed into a personal stash for myself only. I don’t want the smell to be overpowering, and I also need an extreme amount of discretion. I don’t want to use any un-natural lighting or chemicals if I don’t have to, and I would love to hear your BEST tips and suggestions for me.


5. How tall, and how wide can I expect this plant to be, and is there a way of keeping it to a minimum size to reduce visibility?
Not unless you plan on making the lights turn off before the sun decides. Otherwise you are looking at a plant that will be growing until October.


3. Can I successfully grow an indoor plant with no un-natural light sources?
Yeah. If you are trying to get descent yields I hop you are growing in a sun room.
