Cannabis seeds are very sensitive and need specific conditions to grow or they can fail to germinate. To ensure germination, and improve the health of young seedlings ensure you pay particular attention to this initial stage.
As said earlier, there are various design types for the HVAC system. So here are some rules to remember. Place the inlet and extraction fans at opposite sides of the room if you use them. Use aluminum ventilation ducts with steel wire to connect fans with the outer space. Find a good place to mount ducting and use as small bendings as possible. Use an airtight duct collar to connect ducting with fans and with pierced holes at walls if you have them.
It is a myth that you need a huge space to grow quality marijuana. A small-scale grower can start in a tent, a closet, or even in a designated area in a spare room or unused corner of the house! Here are a few helpful tips to get started.
Many growers use fans connected to ducting to extract the hot air from the room and another inline fan to bring fresh air to the room. In this type of equipment assembly, the fans are mounted on the opposite side of the room/tent. Their sizing is described in the section below. The airflow of both fans must be the same. Otherwise, the vacuum or high pressure could occur in a tent/room, which is not desirable. When you are mounting ducting, the ultimate goal is to use as few bendings as possible to avoid large pressure drops and insufficient airflow.
The growing medium you choose is where your plants will develop their crucial root system. The type you choose will also affect the way you set up your grow room space and the initial purchases you have to make. So, it’s important for you to understand the different types of mediums for growing marijuana, from the start.
Medium choice and preparation
Vegetative stage: 400-700μmol/m2/s.
The basement is insulated well since the ground surrounds the walls. You want to ensure your room is well insulated to lower the cost of your HVAC system uses. You can mount Rockwool, which is an excellent insulator, on your inner walls. Rockwool is costly, but it pays off in the long term in most cases, so you should keep that in mind.
While growing high-quality marijuana without lights indoors presents its share of unique challenges, it provides a realistic alternative to investing in expensive grow lights and paying lofty electric bills. If you want to try your hand at growing indoors with natural light, weigh your options and consider the locations and practices described here. Most likely your home and its design will present a way to harness solar energy from Mother Nature to fuel your grow.
The plants grown within receive natural sunlight while remaining in a controlled environment that protects them from harsh environmental factors like wind, rain, and hail, as well as the detrimental impact of insects and other pests—not to mention theft from unscrupulous human thieves. Greenhouses also allow control of environmental factors like humidity. They rank as the most turn-key method of growing cannabis indoors without artificial lighting.
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.
In a south-facing room, large bay windows allow enough room to grow cannabis if sunlight can enter the room for several daylight hours. In rooms with bay windows or sliding glass doors, cannabis plants will do best when placed close to the glass. You don’t want your marijuana plants too far from the windows.
Attics and Skylights For Growing Pot
Patios with translucent roofs are another ideal location for growing cannabis without lights. These areas usually have concrete or brick floors, which are great surfaces for regular water, cleanup and general maintenance of cannabis plants. Having a roof over the plants provides them limited protection from the elements, but definitely shields them from two big dangers: heavy rainstorms and hail damage.
When growing outdoors is not an option, greenhouses are one of the most obvious methods of growing indoors, and there’s much to be said for these stand-alone structures. In many ways, they capture the best of indoor and outdoor cultivation.
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.
Conservatory, Solariums and Sunrooms for Growing Weed
Because light is absolutely necessary for cannabis plants to grow, most home growers invest in expensive lighting systems to simulate the light spectrum of natural light. This usually is accomplished through utilizing high-pressure sodium (HPS), metal halide (MH), or light-emitting diode (LED) lights.
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.

Is my home a suitable environment for cannabis?
Cannabis plants need plenty of bright light or direct sunlight. Southeastern and southwestern exposures provide the most direct sunlight per day, followed by southern, eastern, and western. If you’re dealing with a northern exposure, your cannabis plants won’t have enough direct light to thrive. You’ll need to supplement with artificial light.
Make sure your cannabis plant gets enough light
Rotate your plant. “Growing with just a window, your plant is going to bend itself towards the light constantly and will benefit from regular rotating. I was rotating my cannabis plant twice a day to keep it growing relatively upright,” said Jimmy.
