Ætrium-4 Train
Multiple Ætrium-4 tubs are connected together into
trains with the Matriarch at one end. Each tub measures
42” x 54.5”. In larger rooms, the trains can be mount-
ed on rails for easy movement. For dense lighting can-
opy, the trains are pushed together. For service access,
any train can be moved sideways to create service
space like an accordion. In this way, room capacity can
be increased by up to 25%.
Each growth tub contains 20 planting locations even-
ly distributed in 4 columns by 5 rows. Each hole is
designed to house a 3.75” net pot. Every net pot is
surrounded by aeroponic spray heads that deliver the
fresh nutrient solution from manifolds intrinsic to the
growth plate. The growth tub is essentially a holding
chamber for the plant’s root masses.
Aeroponic systems, like that found in the Ætrium-4
Growth Tub, offer some distinct advantages to indoor
horticulturists. Because the roots are suspended in the
air and sprayed with nutrient solution, they have access
to an abundance of oxygen. Roots in an aeroponic
system have an infinite ratio of oxygen to moisture and
this creates the perfect environment for nutrient absorp-
tion. This bounty of resources accelerates the photosyn-
thesis process and equates to not only faster growth
rates, but also a better use of resources. Aeroponics is
the most efficient form of hydroponics using less water
and nutrients than any other growing method. In fact,
the Ætrium-4 growth system is capable of producing up
to 40% faster growth rates while using only 10% of the
water and only 30% of the nutrients when compared
with soil-based alternatives.
