Always keep in mind that the general idea is to create an environment where your plants will prosper. The better they carry out their photosynthesis, the better your output in regards of quantity and quality, what growers refer to as “yield”. We will now study in great detail what your plants need:
Make sure to seal your windows and use a carbon filter against the marijuana scent. Think about using extra locks or even cameras especially when growing in a warehouse. Don’t put your crop at risk.
There are different nutrients blends that you can use. It will also depend on the growing cycle of your plants, and you’ll need to be careful not to go overboard and burn your plants with too much. Nitrogen toxicity is a common downfall of too many grows.
Creating the right lighting, air flow, humidity and temperature will change your production output massively. A grow room will provide a unique learning and business experience for you.
You can choose LED or HPS/MH lighting for your indoor production. A 400-Watt for vegetative phase and a 600-Watt HPS lamp for flowering phase for every square meter will be a great start. If you can make the investment use LED lamps because they will last forever, and the technology is finally catching up to the HID (HPS and MH) lamps most professional growers have used for years. See our full info on lights here.
Make sure to find a room or grow tent that is airtight. The stench of marijuana could easily reach and bother your surroundings. Whilst air circulation and fresh air is very important, make sure that all your out-going air will pass through a carbon filter. An air extractor will remove the heat for the lamps to keep the temperature stable as well as remove the odour of the plants.
Setting up a growing facility isn’t cheap. Even the basics requirements needed can add up cost-wise. The main advantage is that indoors you are protected from natural challenges and road blocks. So setting up might be more complicated than outdoors but the results and your margins will be a lot greater. Testing things out with a single grow box might be a good solution to get started because they provide many factors needed for growing growing cannabis on a small scale.
Growing indoors will provide you the power to influence all necessary inputs for growing big, healthy, cannabis plants with those big, sticky buds you dream of. This includes lights, nutrients, water and humidity, ventilation as well as temperature. Instead of being dependent on weather and soil you can optimize your production for maximum yield.
Humidity describes the amount of water in the air. You will need just the right amount of moisture in the air that will push the growth of your plants will at the same time not too much humidity because it will cause fungus and mold.
Whether starting with a single grow tent, a stealth grow box, or a full scale commercial marijuana grow room, how you set up your growing space goes a long way in determining your final yields. In this chapter we'll cover the 6 most important factors for setting up a successful grow room for your cannabis plants. Grow
The best way to do this is to keep your ballast outside of the grow room due to the amount of heat that they generate. However, this may be an added benefit when it comes to growing during colder months, although during the springtime and hotter months it’s not a good idea. If you can’t keep it outside of your grow room, you’ll need to place it on a wooden shelf up high and as far away as possible from your plants.
It generally costs more to turn a full room into a grow room rather than simply buying a grow tent; you need to prepare the entire room so that it can efficiently hold and keep cannabis plants alive. Although it may cost a bit more, it’s definitely a much comfier way to grow cannabis. You can get larger yields, grow larger plants and have enough space to get everything done in the one room, which can be difficult in grow tents.
In order to hang your lights correctly, you’ll need to measure out how much space each light is going to cover and find the exact center of the bulb in order to make the right hole in the ceiling for your plants.
Many people think that the best way to set this up is by placing the extraction duct at the top of the window and the inline duct at the bottom. This is a major mistake – most likely you’ll end up taking in the exact same air that you’re trying to ventilate out of the room. One of the most simple ways to do this is to use the window to extract air and then make a grid on the door to the room. This is called passive intake and doesn’t require any sort of inline fan.
For the best results, you should place the humidifier in the middle of the room alongside a fan, which helps to distribute humidity evenly. If you can, try and move it to the other side of your plants after a few hours in order to avoid the plants closest to it getting a bit too much humidity, which can end up causing fungi.
When it comes to the inline fan, if you’re going to use one instead of just using a passive intake vent, it’ll need to be on the other side of the room in comparison to the extraction fan. You’ll need to place it down low. If possible try and use some sort of cushioned base to avoid the vibrations travelling through the floor.
Once you know where you’re going to be setting up your ventilation system and how you’re going to be supplying fresh air, you’ll need to install the extractor fan and inline fan, if you’re using one.
You need to block any and all light from getting into your grow room. You’ll also need to get proper reflective sheeting in order to cover the walls, floor and ceiling of your grow room. You can cover the walls to about a meter and a half if you want to save on materials. We recommend using a stapler to attach it to the walls and ceiling, as double-sided tape can easily come unstuck once the room heats up.
If you clean your room thoroughly before you start growing, you’ll be able to keep insect and fungi infestations at bay for much longer, which is incredibly important – if your indoor grow room becomes infected it can be quite hard to get rid of it for your next grow.
