DIY grow box: the first steps

Of course, before building a DIY grow box make sure you have a plan for what you are doing; it will in fact be necessary to calculate the space we need and all the essential requirements for the growth of indoor plants, i.e. lights, ventilation, nutrients, water, etc. Keep in mind that install your automatic grow box it is a great investment. This includes physical and economic work! Surely the best rule to follow at this point is “measure twice, cut once”.

The size of your complete grow box largely depends on how much marijuana you want and how much space you have available. It also depends on the type of cannabis you want to grow. If you are growing for medical purposes, the amount you grow will typically be up to you. The sensitivity and type of disease of the person intending to use it determines the volume that should be grown. You don’t need to be an expert in medicine dosage to calculate the amount of cannabis needed for your condition. Everyone can decide for himself, how much he needs.

A lot of average patients have an average use of between 1 or 2 grams per day. This means that for personal use, you will need to pull about 1 or 2 ounces per month. Theoretically, you could have a crop every 2 months because there is about 60 days of a flowering period. If you want 2 ounces a month, you need to harvest double the amount, in this case, 4 ounces of cannabis; while, if you are an occasional consumer, a mini grow box may bastards, or a small grow cabinet for growing a few cannabis plants.

Where to place the craft grow box?

The placement of your indoor grow box is important for a number of reasons. First of all, you may need discretion and privacy for your grow operation. You’ll also need to make sure it’s a place you have control over. There is no point in trying to grow indoors if it doesn’t allow you to control the environment. In fact, it is known that a cannabis grow box requires various equipment of essential importance, including a grow box lamp or the lighting necessary for the Indoor Cultivation of cannabis plants, the grow box heater which is a tool for protect plants from the winter cold by heating the cultivation environment; Another tool is also extremely important, the grow box humidifier is used to ensure the right humidity for cannabis plants throughout their life cycle.

If you are in an apartment, you want to keep the location of your cannabis garden discreet. Therefore, it is advisable not to choose a seat near the entrance but instead, somewhere in the back. Use an unused room, a special wall unit, or even a closet as a grow location. Avoid rooms with large south-facing windows, especially on the upper floors, as you may run into problems with heat control. Believe it or not, the sun gives off a lot of heat.

Above all, the marijuana grow box should be suitable for the cannabis strain you are planning to grow.

Equipment for growing cannabis

If using electrical products, local safety regulations must be observed. Make sure that the amount of power used is adequate for a range supported by your connection. Do not use many shorter cables connected together to form a long line, but use a long straight cable. This minimizes the risk of electrical failures.

Ideally, your grow room should ensure the safety of risk-free water and electricity. If you can configure them so that they are both close together, it will be much easier on yourself.

Don’t underestimate water, it is very important for the life of cannabis plants. It is required – on a daily basis – and in large quantities. You spend much more of your precious time watering if there is no water source near your grow room. If you are in an ideal position to locate good water sources, try connecting a pipe from the nearest tap and running it in the grow room. Use a submersible pump if you use hydroponics to grow a lot of plants and need to empty the tank.

The area must be well ventilated. It may be enough to use a window, an air duct, or even a chimney to ventilate the room, but you need to make sure there is good airflow. This is especially true if other ventilation systems are not used to help. Use ventilation pipes to bring in fresh air and remove used air if windows and chimneys are too far from the grow room.

Also remember that air takes time to travel. If your fresh air has a long distance to travel to reach your grow room (due to unusually long, winding pipes or ducts), you’ll need to make sure you use fans to circulate the air.

You also want to make sure the space is clean. Start with the floor first and then work up to the walls and cleaning the ceiling. After cleaning, put the plants back in their place.

An asphalt or concrete floor is great for indoor growing because it doesn’t hide hiding places for tiny bugs and insects and is easy to clean. If a tiled floor cannot be provided, any covered floor or a thick layer of plastic may work as well. If using carbon dioxide (CO2), properly insulate the garden to avoid leaks.

Once you’ve thought about all of these potential problems and developed a well-built plan for your personal grow room, you’re ready to get started.

Discreet cultivation grow box at home

There are a variety of ways to set up your grow room. Before choosing one, determine your needs and localization requirements. For example, when growing marijuana indoors, you need a lot of light. Without enough light, the plant will not grow.

If you’re short on space, perhaps the smallest space you can get from growing marijuana is a closet. In fact, a space of 1 x 0.5 x 2 meters is large enough to produce enough medicinal cannabis for a single patient. And due to its small size, a cabinet is appropriate for growing marijuana – it can be covered very easily. You can also put in a 250 watt HPS light.

Grow box lamps, the answers to all doubts:

Another type of indoor grow room that is possible in tight spaces is a wall unit or hidden storage space. Here are some estimates for the lighting you will need in various wall cabinet sizes:

1 x 1 x 2.5 meters for 400 or 600 watt HPS lights

1 x 2 x 2.5 meters for 2 lights 400 or 600 wattHPS lights

2 x 2 x 2.5 meters for 4 x 400 or 600 watt HPS lights

2 x 3 x 2.5 meters for 6 x 400 or 600 watt HPS lights

You shouldn’t forget that you also need space to move and work in the grow box. The above measures only cover the area for marijuana. They do not include the space you will need to move around. Therefore, plan to add some space to the numbers above. An extra fifty centimeters space around the areas will suffice.

We also advise you to carefully evaluate the type of strain you will germinate in fact some cannabis genetics will really grow much beyond the 2 meters allowed by most grow boxes on the market. Choosing autoflowering cannabis seeds for your first crop is a smart choice.

Grow Marijuana in a tent

Camp tents are a very popular and smart solution and my favorite. A marijuana grow tent is a light-proof rectangular tent where you can place containers with the soil or hydroponics system. Usually flood and drainage systems or drip irrigation are used in a tent, but they don’t work as well with the nutritional film technique.

They are black on the outside and totally light-proof, coated with a reflective material on the inside to use the light more efficiently. Camp tents allow you to completely customize the environment your marijuana plants live in, including temperature, light intensity, humidity, and location. The tents are portable, durable, washable, light and water resistant and are available in a wide range of sizes to suit the needs of every hobby.

DIY grow room for growing cannabis

There are advantages to using a grow room for growing marijuana. One is the grow box fan, which is a tool that ensures the circulation of fresh air in the growing environment of cannabis plants, which can be used to freshen the air. The grow rooms can also be connected to the outside air through, for example, a window. This can work in a cellar because a cellar is (usually) built underground. The Earth keeps the temperature stable. This means some fans will be all it takes to keep the area cool.

The penthouse, on the other hand, is not as good as a choice because it does just the opposite. The temperature is highly unstable; it will be very cold or very hot, depending on the season. The same for rooms and/or wall units facing south, especially if there are large windows or are on the upper floors. During the summer, the plants can get quite overheated. Here are some potential room measurements and the light requirements you want in a room of that size:

3 x 3 x 2.5 meters for 9 x 400 lights or 600 watts of HPS light for a fixed system

Remember, make sure your room is adequately covered and insulated so that it stays dark during dark times. You want to control the lights, otherwise you may end up with a sudden and inopportune bloom.

Grow box coating with Mylar

Keep all walls in the grow room covered with something that reflects light, such as white plastic or white paint. The best material for this, however, is mylar; Mylar is a reflective material that allows complete illumination of the entire cultivation area where our cannabis plants are located, which will finally be able to receive the light from top to bottom, producing better yields.

It is a good idea to install other devices at the same time. Some examples are measuring devices such as a hygrometer or a thermometer. You will also need to set up the substrate (your growth level at the bottom) and decide whether you plan to grow in soil or install hydroponics. Hydroponics are much less susceptible to bacteria and therefore soil, making them a good choice in some cases.

Clean grow box to avoid mold and bacteria

It is of great importance that your grow room is kept clean. If you don’t keep the grow room clean, you put your plants at risk for fungus, mold and disease. The disease can escape out of control very quickly in the hot, humid environment you have created. It is absolutely vital not to let mold or dust build up in out-of-the-way corners or, even worse, on the plants themselves.

Also, you want to be careful to keep animals away from your plants. While this may not seem like a difficult task, cats are very curious and persistent creatures, and dogs love to get into trouble. Don’t let them spoil your crop! In addition to causing problems, animals can carry insects and bacteria that have a high potential to spoil the crop.

Before and after starting a new growth cycle in your grow room, it’s a good idea to disinfect. Clean the entire site with some sort of cleaner, just to make sure you don’t have to deal with latent pests or bacteria in future crops.

Cleaning also means cleaning up the waste your plants create on their own. Inevitably some leaves and leaves turn yellow and die off. Make sure you remove them right away. If you end up having problems with fungus or mold growing, you will likely have to abandon that crop.

Grow box kit for cheap and fast cannabis cultivation

To optimize the indoor grow box we will need a led lamp (or other types of lamps), grow box extractor, grow box fan, etc. Precisely for this, grow box kits exist. The grow box kits are kits created specifically to grow cannabis quickly and cheaply, in fact buying all the tools for the ideal cultivation in a single kit will allow us to save large sums of money and to grow marijuana plants immediately.
