To maximize the amount of daily sunlight your plant receives, work with the seasons. The total number of daylight hours vary depending on where you are, but in the Northern Hemisphere a good rule of thumb is to germinate your seeds around the Spring Equinox.
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.
Make sure your cannabis plant gets enough light
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.
“I make zero effort to control the climate of my grow spot. If you’re growing without a light, that plant will be just fine in regular household conditions that are suitable to us humans,” explains Jimmy B Harvests, a YouTube creator that documents his adventures in growing cannabis, along with other fruits and vegetables, at home.
Autoflower vs photoperiod plants: what's the difference?
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.
Window sills, although close to glass and fine for seedlings or young clones, do not have the space necessary for robust plant growth. Certainly, starting plants in these areas is possible, but before they reach more than a foot of vertical height they will require a more permanent location to mature.
If space limitations make owning a greenhouse impossible, there are other options available to those who want to grow cannabis indoors without lights. Like greenhouses, these alternative methods must harness natural light from the sun.
Besides greenhouses, the most obvious cultivation option available to home cannabis growers is a “sunroom,” which are popular retreats for many homeowners. A variety of household plants thrive in sun rooms across the country, so there’s no reason cannabis can’t flourish in the same environment.
Patios with Translucent Roofs For Growing Pot
Cannabis growers can choose from a number of growing locations ranging from greenhouses to large windows, but each location can attract unwanted attention. Growing cannabis with natural sunlight requires as much light as possible to hit the plant.
If not built into the structure of an existing home, some people opt to screen-in a large porch area. The trick to a good sunroom for plants is providing a way to receive as much unobstructed light as possible. Screened-in sunrooms provide an excellent means of allowing sunlight to reach plants, but this material provides less protection from outdoor environmental factors like low temperature. Sunrooms in the United States should face southeast or southwest (followed by south) to receive the most sunlight possible.
Simply stated, cannabis cannot survive when not allowed to engage in photosynthesis, and exposure to light is part of that process. Photosynthesis allows the plant to absorb the energy of lights from the chlorophyll in its leaves and convert it into energy. Carbon dioxide (CO2) and water (H2O) nurture the plant and allow it to create sugar for energy.
Conservatory, Solariums and Sunrooms for Growing Weed
While curtains or plastic film can keep a grow out of visibility, they can also reduce the amount of light reaching the plant. Growers may require a supplementary artificial light to provide the plant with enough light if they intend to hide the plant.
Now that you have the Guide to Growing Marijuana Without Lights, it’s time to get growing cannabis!
Because the sun is a full spectrum light, the light it gives off is white in color but the fact is it has various color energy rays it gives off. The sun is capable of giving off various color energy rays like violet, blue, green, yellow, orange, and red.
Among all the colors given off by the sun, the blue ray given off during summer is believed to help enhance the growth of plants. During summer, marijuana plants grow tall and big to their full potential as they await the fall to flower.
Towards fall, the sun produces redder spectrum rays, inducing the plants to produce hormones which help them develop flowers. During the fall, the nights are longer than days hence the pollen sacks in males, THC sticky resin in females if left un-pollinated. If you wish to turn on the room lights at night when the plants have started the flowering stage, it is advisable to either first move them to a dark room without light licks or use blackout curtains.
Relationship between marijuana plants and sunlight rays
Even with the growing fame of the legalization of marijuana, there still remain a certain percentage of people not in support. It is for this reason that so many private growers will not come out right to let their neighbors know that they are growing it indoors because of the fear of scrutiny. With growing marijuana indoors using natural light, the positioning of these strains is most likely going to be in a place that will easily be detected by your neighbor.
Most of the available information on the indoor cultivation of marijuana bases on the use of artificial light. This does not mean that growing weed indoors without lights will not produce good results. Growing your weed under natural sunlight works well providing you have a light room that also has good ventilation.
With this mode of growing, the position of the garden from the outside or the natural light really matters. Growing marijuana indoors using natural light is most effective for people with smaller gardens or those who just need to grow a few plants for medical or recreational use.
What some gardeners do sometimes is just plant several seeds in one larger container and keep on trimming them as they grow and crowd each other. Remember that for the better development of a marijuana plant access to sunlight is the biggest prerequisite or else the buds will not be as enticing as they should be.
