Importance of sunlight when growing marijuana
Once again, this depends on the type of cannabis that you are growing. Photoperiod cannabis starts flowering when it is exposed to a minimum of 12 hours of uninterrupted darkness each day. After they bud, you must continue providing them with long nights until their harvest, or they might go back to the vegetative stage.
How much sun does marijuana need?
When you grow cannabis, you need to understand how much sunlight your plant will need, but you should also realize that the sun is both a source of light and a source of heat. You want it to be warm enough for your plant, but not too hot. Temperatures between 60 and 80 degrees are ideal.
Bottom line: Photoperiod plants will require several months of your time and attention, whereas some autoflowering plants complete their life cycles in as little as 49 to 56 days. This is something folks might not consider when getting started with cannabis — you have to tend to it often and be present through the plant’s life cycle. So if you’re planning a vacation or work might take you away from home, an autoflower strain might make more sense for you.
Will growing a plant indoors without grow lights leave you with wonky plants? Lower yields? Less potent flower?
Photoperiod plants need to follow a specific light schedule, particularly during the flowering period. These plants need 12 hours of complete darkness to induce flowering and throughout the flowering phase until harvest. “If you can’t get the environment dark enough, that plant is just going to keep on growing and might get too big for the space you have,” added Jimmy. Our homes are full of light, so to assure the darkness needed to induce flowering, put the plants in a closet each sundown and back out in their window each morning.
Autoflower vs photoperiod plants: what's the difference?
But can you simply stick a cannabis plant in a nice sunny window and let it do its thing? Read on to understand what to expect if you choose to grow cannabis indoors au naturel, along with a few tips and tricks from experts to help your indoor plant thrive in a minimal setup.
Autoflowering plants begin flowering automatically based on their maturation. When they reach a particular age, they flower, regardless of how much sunlight/darkness they are getting. These plants do not require the complete darkness that photoperiod plants do, meaning you could leave them out and about overnight and they will be fine. Another reason you might want to choose an autoflower variety is if you’re short on time since their growth cycle is shorter than it is for photoperiod plants.
What to expect when growing weed indoors without lights
Not necessarily. “The more effort and energy you put into a plant, the bigger and better your harvest will be,” said Jimmy. “I think that’s a pretty universal truth in the gardening game, but I’ve definitely been surprised by how well plants can do without the elaborate tents, fans, filters, feeding systems, and so on.”
Successfully growing a cannabis plant indoors is all about covering the plant’s basic needs: air, light, temperature, water, and nutrients. So, if you get those things right, your homegrown cannabis plant could provide much more than a fun experiment. And considering that indoor cannabis plants can grow a few feet tall and equally wide, you should anticipate young plants to take up more space by the time they reach maturity.
Full sun is probably the trickiest level of exposure to achieve because while many plants need full sun to set buds and flower, some plants cannot handle the intense heat and/or dry conditions that often come with that much sunshine.
Plants that prefer full sun are by far the largest group of plants you will encounter. The vast majority of flowering annuals and perennials need full sun provided their moisture requirements are met. Vegetable gardens also are generally best positioned in the very sunniest location you can find, although a few vegetables and herbs (mostly the leafy types) will tolerate some shade.

While there are gadgets available that measure sunlight exposure, using gadgets is not an exact science. In climates where a rainless summer day usually includes clouds that come and go might result in identical readings to a region where a rainless summer day means piercing blue, cloudless skies from morning to night.
For a planting area to be considered a full sun location, on most days the area must receive six to eight hours of direct sunlight mostly between the hours of 10 a.m. and 4 p.m.
