Temperatures can also vary quite a bit. Provide good insulation to minimize the need for heating or cooling.
Light-tight
When you have found the ideal location for you, the building can begin. Provide good light protection in the cannabis grow room. Not only to prevent light nuisance, but also for the plant.
For optimal flowering, the plant needs 12 hours of continuous darkness and 12 hours of continuous light. When this process is disturbed, it can have a significant effect on the yield. Plants can become hermaphrodite or even an entire crop can fail. This is called light stress. So make sure there are no holes or cracks through which light shines. Then the weed loft has good light protection.
Air-tight
It is important to make the grow room not only light-tight, but also airtight. First for the smell. Not so much in the growth phase, but once the plants are in their flowering phase and producing beautiful buds, the development of their fragrance also starts. The plants will begin to give off a strong odor. Especially at the end of the flowering phase. You don’t want this scent to spread outside the room. You will get used to the strong cannabis smell of your plants yourself, but your neighbors probably won’t. Second, even the smallest crack can allow pests to enter and disrupt the growth of the plants. Thirdly, it is important to have a well-insulated room, so that you can regulate the climate yourself.
Close all holes, cracks and crevices!
Seal them with sealant or sealing or non-transparent tape.
You have found the ideal spot and made your grow room light and airtight. Now you are going to try in your new booth to create the best possible climate for your cannabis plants. The better they are having a good time, the more profusely they will grow and bloom.
Air circulation cannabis grow room
In order for your cannabis plants to grow and flower properly, they need carbon dioxide (CO2). They get that CO2 from the air around them. Air exchange of a grow room with weed is important. If you don’t supply fresh air, they will have used up all the CO2 at some point. The growth of the plant will then slow down and the plant will become less healthy. The fresh air is drawn in through the inlet opening. The air holes provide fresh air and CO2 when growing weed.
Growing cannabis without good ventilation is therefore impossible. Make sure that no bugs or other vermin can get in and that no light shines through it. You can prevent this by connecting a hose that you place in a bend or by making a filter. For this you use a filter from a vacuum cleaner, extractor hood or the automotive industry.
In a small grow room, the inlet is passive. This means that no extra fan is needed to get the fresh air in.
By extracting low-CO2 air from the grow cabinet, you create a negative pressure in the room, so that fresh CO2-rich air is automatically drawn in. You do this with your extraction, extraction system, extraction fan. It can be placed both inside and outside the room.
Always grow weed with a carbon filter to prevent odor nuisance. A carbon filter is a large tube filled with carbon. The carbon absorbs and neutralizes the chemicals that cause the odors. A carbon filter does not last forever, so it is recommended to replace it after 4 to 5 breeding rounds.
Normally the inlet side is at the bottom of the grow room, low to the ground. The warm air from the lighting is extracted through the outlet at the top.
A plant that can absorb a lot of carbon dioxide will give a good yield.
There are even CO2 enrichment devices available, which give cannabis a boost during the flowering period with extra CO2. The result is thick, firm buds.
Moving air initiates evaporation. This prevents you from getting damp spots in your growing medium or elsewhere in the room. Warm moist places are ideal for mold.
Climate
Cannabis thrives best in a good climate. That means growing weed with the right humidity and temperature. This is different for each phase of the plant’s life cycle. Climate control, checking and adjusting the temperature and humidity is therefore recommended. But how do you manage the climate in your grow room?
