I installed a sealed fan room to house the 6″ inline fan mentioned above. This sat in the top inside of the cabinet, pictured below.
Now that my fan room was set up, I allowed the exhaust to escape upward into a carbon filter. I mounted the filter inside a Rubbermaid tote to make the whole setup more discrete.
Affordable medicine is a right, and medicinal Cannabis sets a standard for patient autonomy. Enjoy producing your own medicine.
The solution I came up with was to place the duct work outside of the cabinet.
After months pouring over cannabis related text and furrowing my brow at various nooks throughout my home, I saw through the problem. I would build a stealthy grow cabinet!
When all was said and done I harvested 264 grams (9.3 ounces).
My inline fan with had 6″ opening (28 square inches) so I would need 56 square inch opening. I went with two louvered grills that were 5″ x 8″ which gave me 80 square inches – 30% for the louvers = 56 square inches. Perfect!
Keeping a door open is not a viable option for the stealthy gardener like me! I decided to use some creativity.
I built and installed 4″ x 10″ x 48″ wooden housing for the duct work for the exhaust of the Cool Tube (picture 3rd down). Next, three 6″ duct flanges into the back wall of the cabinet leading into the duct work spaced vertically 9″ apart.
We learned above that the cabinet is 24″ deep. Now this Cool Tube was 20″, hardly enough room to attach two 6″ flex ducts for ventilation without having to keep a door open.
I chose a High Pressure Sodium bulb. Since these produce more light from the side(the long side as opposed to the plug and tip of the bulb), light coverage could be maximized by positioning them front to back. Some creativity was required to install the Cool Tube to keep my HPS bulb from becoming too hot.
The first thing to deal with was the Intake and exhaust – a clean environment and fresh air for my plants.
Momentarily discouraged, I quickly scrapped the idea of a dedicated room filled to the brim. I began with getting clear about my intentions; I wanted to inconspicuously and autonomously produce my medicine. This was a much more respectable and realistic goal, and one that I could embrace.
This had been a long-time dream of mine, and I fondly imagined my first harvest, curing my flowers to perfection, and collecting their resin for concentrates. I saw myself carefully journaling their progress, and eventually becoming an expert caretaker of myself and my marijuana garden.
Next, I faced the issue of providing my plants their light.
My sights set, I loaded Google's 3D rendering freeware, Google SketchUp, and got to work.
I vented this area with a 4″ opening that opened into the fan room.
Sirius: This is definitely an advanced method of creating a grow box, but he makes sure to include a lot of things one needs to consider when creating one, such as ventilation and making sure to leave room for everything you need. Do you have a better/more practical/more efficient design? Let us know so we can share with the world!

A rule with any grow space is to have the intake's opening twice the open area of the exhaust's.
Sirius: Google SketchUp can be pretty tough to use without training, especially if you've never used it and you just want to design one thing. Rest assured: some paper, a pencil, a little math, and careful planning will work just as well!
Sirius: This is a great point! In any enclosed grow area such as a tent or grow cabinet, it's important to have a larger opening for intake than for exhaust. This will maximize the efficiency of your fan in addition to keeping it working for longer. Plus, this will keep tents from "bowing" in, reducing your grow space.
Final Harvest Weight: 264 grams (9.3 Ounces)
Important: The opening for your intake hole should be about twice the size of your exhaust hole.
A fan speed controller and light timer are mounted on the outside of the fan room.
Next to the fan room is space for other more technical things. Here we find the ballast and command switching station.
Cannabis plants need CO2 to perform photosynthesis , which is vital for plant growth. During this process, plants take in water and CO2 and convert them to sugars by applying the energy they absorb from light so with good ventilation you are actually “injecting” CO2 into your grow room, providing what they need for this vital process.
220V x 15A = 3300W.
With some minor differences, obviously.
You need 1m x 8 wood beams for (A), 2m x 8 wooden beams for (B), and 1m x 2 or x 3 beams for (C). The amount of beams you need on top depends on the weight of your light fixture, exhaust fan, and carbon filter.
Unfortunately, you cannot make them at home (unless you have experience with electronics), so you’ll have to buy them.
Prevents mold and bugs.
When building your grow room, you can make it as big as you want to and out of anything you have available as long as you make it light-proof, air-tight and waterproof.
So let’s say that the label says 15A and 220V; Now you have the information you need so it’s just a matter of applying it to the following formula :
The carbon filter goes directly connected to the exhaust fan (sometimes it’s connected by duct tubing) and it’s what will eliminate the strong cannabis smell before letting the air out, a carbon filter is crucial if you are growing indoors in a place where cannabis cultivation is illegal, this will avoid problems with your neighbors and the police.
After you have all the poles and connectors ready, you need to cut the plastic sheet.
So read along on how to build an indoor cannabis grow room!
The plastic sheet should be measured on the grow tent before cutting so you don’t have to redo it, make sure it doesn’t have holes to avoid light leaks and if it doesn’t get too hot where you live you can use 2 layers of the sheet to make the tent more resistant.
Apart from having a grow room air conditioner, ventilation is the only way to keep the temperature down. Most growers that grow under LEDs shouldn’t have a problem with this but if you’re growing under an HPS for example, you’ll definitely need ventilation.
First of all, you need to know that all power outlets are on a circuit, meaning that it doesn’t matter if you’re connecting the light fixture to one outlet and the exhaust fan to another, if the outlets are in the same room it’s most likely that they belong to the same circuit and circuit can only take a specific amount before they overload.
To start building your own indoor growing space you’ll need some basic materials and tools, some you might already have at home. You’ll need:
Just remember that this is the max wattage the whole circuit can handle and not the max wattage one individual outlet can take!
Helps keep temperatures down.
Another great benefit is that it prevents mold and bugs because most pests thrive in hot and humid environments so by keeping the humidity and temperature on point, it’s most likely that bugs won’t be attacking your plants.
If you fail to keep air inside, your exhaust fan won’t work properly, it won’t keep the cannabis smell contained and it will be easier to get bugs.
The exhaust fans ensure a good air exchange , this is crucial to the growth of your plants because the air exchange will provide the CO2 your plants need while letting out oxygen.
Now that you’ve identified the circuit you want to connect your equipment to, take a look at the amperage, it should be listed as 5A , 15A , or 20A , and should inform the voltage which will vary from place to place but in general, is either 110V or 220V.
If you want to start growing your own cannabis you don’t need to spend a lot, despite the cost of a ventilation system and lights, you can easily build your own indoor growing space by yourself.
Even though the plastic sheet is waterproof, you will need to coat the inside of the grow tent with a material that reflects light like a mylar sheet or a white plastic sheet.
A grow room fan is placed inside the grow room to create air movement above the canopy level, this not only allows the plants to cool down but also sways the plants around, promoting stronger branching that will be able to support the heavy buds that will develop throughout the flowering stage.
Calculating power capacity.
Because wood can get wet and rot , it’s a good idea to cover the inside with 2 layers of material.
One of the 1x2m plywood sheets will need to be cut in half (for the door). You’ll also need 4 door hinges so you can open and close your grow box properly.
The size of the poles obviously depends on the height and size of the grow tent you want to build, but here’s an example to build a 1x1x2 grow tent.
Note: Instead of using mylar, you can use a white plastic sheet, it won’t reflect light as good as mylar but it works great if you can’t find mylar easily.
As you may know, an indoor weed grow room allows us to control and adjust the temperature, humidity, and intensity of the airflow, because of this, your grow room must be air-tight.
As you see in the image above, you’ll need 8 poles with 1m each for the top and bottom part of the structure, 1m x 3 poles for (E) and (F) and 2m x 8 poles for (C) and (B). If you want to make it easier to handle and assemble, you can cut the 2m poles into 1m x 8 poles and connect them with PVC fittings.
A grow tent is the best DIY grow space because (depending on how you build it) you can easily disassemble it when you need to and then mount it again without needing anything else.
You’ll need 1x1m x 1 and 1x2m x 4 plywood sheets, remember they need to fit perfectly so there are no light leaks and the grow box is as air-tight as it can be.
