The appreciable difference between the Homebox Twin and all the other homeboxes is the second room on top.
The Homebox Twin offers the possibility to create two independent climate zones and light cycles, because each room has separete air in- and outlets.
The total size (120 x 80 x 200cm) of the Homebox Twin partitions in  the taller, lower room with a size of 120 x 80 x 140cm and the 120 x 80 x 60cm large smaller, upper room. So, in effect you have a classical homebox and a clonebox in one. How you use the total deposit space of 1.9m² you can decide on your own.
Practical zippers allow for a quick and simple access to the light- and airproof greenhouse.

The mounting of the Homebox Twin is incomplex and quickly done, whitout the use of tools.
