It is most common to use the Homebox or other Growtents in combination with a Cooltube. The Cooltube can be integrated neatly in the air exhaustion. Thus the bulb contained in the Cooltube gets constantly chilled by the air blown by. This is the best solution for all temperature problems in the Homebox. Also the plants can't touch the enclosed lamp which prevents harm to the plants.

This setup is exemplary (we use the Homebox L here):

The Active Carbon Filter (1) and the Fan (2) are tightly joint by a duct coupler (you can see the coupler (9) on the image below). This allows to suspend them together by Tension Belt (3). Tension belts are included with the Homebox.

Fan and Cooltube with reflector (6) are connected by Air Tubes (4). For the connection Duct Hose Clamps (5) are used.

Another hose finally conducts the consumed air out of the Homebox. For this purpose every Homebox, depending on the model, offers several exits. As seen on the picture we use the exit on the top (8).

In our example the Cooltube is suspended with a Metal Chain (7) which allows easy and quick adjustation of heigth.

Even simpler is the suspension with Easy Rolls (10). Coiled up in the Easy Roll is a tough thread which can be easily adjusted and fixed in the wanted length. Thus the heigth of the lamp's suspension can be adjusted within seconds.
