DIY stealth growbox from the system

Today we will introduce you to the option of organizing a stealth 2×4 grow tent using engineering and straight hands. We have prepared a small instruction on how to assemble a grow box from a system unit. If you want to get a compact box, but you don’t want to assemble it yourself, we advise you to pay attention to the ready-made HOMEbox Ambient Q30 grow tent. Its small size (30x30x60 cm) will allow you to place your home greenhouse even in a confined space.

Necessary equipment

So, for this project you will need:

  • Sistemnik, we used from Chieftec;
  • 4 coolers;
  • LEDs for plants 40 pieces;
  • Driver, heatsink for LEDs;
  • Bolts M3;
  • Alanod for interior decoration.

Build process

It is necessary to remove all the insides of the system unit and leave one frame. Then, on the inner surfaces of the system, we attach planned to reflect the light flux. It is necessary to ensure that your plant receives maximum uniform light from all directions.

Electrical installation

We proceed to install all the necessary electrical equipment. Since we are talking about stealth growing, all the electronics to the maximum must be placed inside the system unit. To do this, we form a kind of technical compartment on the rear panel of the system unit, in which we place drivers for LEDs and a cooler for cooling. We insulate the compartment itself with an planned panel.

Of the disadvantages of such placement, you can cancel, which reduces the usable space for the plant. However, this is not so critical, if you use a large enough system unit, 5-6 centimeters will not really “affect the weather.”


All you need to remember is that at the vegetation stage the plant needs a blue spectrum more, and at the flowering stage it is red, based on this we make calculations. For vegetation you will need: 10 red, 10 blue and 10 full spectrum 3 W LEDs. For the flowering stage: 20 red and 10 full spectrum. It should look like this:



To cool the LEDs, we use a radiator, onto which we screw all 80 LEDs. To do this, we drill 80 holes, place all the LEDs using thermal paste and M3 bolts. To further protect the LEDs, you can use a special plexiglass film on top.

We install the lamp in the upper part of the system unit. Thanks to plexiglass, the LEDs are maximally isolated from the camera with the plant.

Spectrum on vegetation

For good ventilation on the side wall of the system unit, we install 2 fans for blowing. One will cool the technical compartment with drivers, the second will be placed so that the air flow is directed to the plant itself. We put 2 fans on blowing out of the chamber, which drive air through a homemade carbon filter.

The design of the filter is simple – an aluminum profile, to it we fix two grids with rivets, between which we fill in coal, the thickness of the coal layer is about 15 mm.

The airflow of the luminaire must be adjusted in such a way that it starts working simultaneously with the lighting on. The ventilation of the plant chamber must be switched on manually. We power all the coolers through PWM controllers, bring the knobs to the front panel so that they can be adjusted separately.

Conclusions and recommendations

As a result, after assembly, we get a full-fledged chamber for growing plants with dimensions of 43 cm x 18.5 cm x 60 cm. Yes, you may have to study a couple of notes on electrical work, but you will definitely succeed!

If, in the end, the whole process seems too complicated for you, and the resulting structure is unreliable, then we advise you not to waste time building a stealth grow box with your own hands, but consider an excellent alternative – ready-made HOMEbox grows houses. They are compact in size and at an attractive price. In particular, we recommend that you consider the HOMEbox Ambient Q30 model. The external dimensions of this miniature model are only 30x30x60 cm. You can find the full range of HOMEbox grow-tents in our catalog.

We wish you successful experiments and a big harvest!
