A footprint of 120 by 90 centimetres is an unusual size, and the one tent here uses it in a way the other sizes cannot: it is divided in two. That is the whole reason to choose this format.
Why a tent with two compartments
Anyone growing continuously runs into the same problem: flowering plants need twelve hours of darkness while cuttings and young plants want far longer light. In one space you cannot do both. With two separated compartments you run both schedules at once, which means the next round is always ready when you harvest.
The CLOUDLAB 743D
The AC Infinity CLOUDLAB 743D measures 120 by 90 by 180 centimetres and is built as a 2-in-1. It belongs to the Advance range, which means it connects to the climate equipment of that same system. For planning your extraction, what counts is that this is a divided space: two compartments each needing their own airflow.
Budget for two of everything
This is where people underestimate the cost. Two compartments on different light schedules means two lamps on two timers, and it means your extraction has to serve both sides without light from one falling into the other. Work that through before ordering, because a 2-in-1 tent is cheaper than adding a second tent, but not cheaper than one.
When one space is enough
If you grow in rounds, planting everything together and harvesting together, you do not need the division and a plain 120x120 gives you more room over the same floor area. The split only pays if you actually use it.
Frequently asked questions
Can I flower in both halves at once?
You can, but then you are not using the division for what it is for. For one schedule across the full area, an undivided tent is more practical.
Do I need two extraction systems?
Not necessarily two complete systems, but you do need airflow in both compartments. Check the product page for how the ports are laid out.
Does light leak from one side to the other?
That is what the divider is for. Check it seals properly when building, because a light leak during the dark period is the one thing that genuinely spoils this arrangement.
