Dark Box DB80

Grow tent of 80 × 80 × 200 cm, giving 0.64 m² of floor and roughly 1.28 m³ of volume. Steel frame, reflective mylar lining and double sleeves at the ports.

Volume keeps a climate steady, not floor area

Tents get compared on square metres, because that is what you have to find room for. For the stability of your climate the cubic metre matters more, and it rarely appears in a comparison.

A lamp gives its heat to the air in the tent. The less air there is, the faster it warms. Two tents with the same floor area but different heights therefore behave differently: the lower one spikes as soon as the lamp comes on and drops away as soon as it goes off, while the taller one moves more slowly.

At 200 cm tall this tent holds roughly 1.28 m³ of air, against about 1.15 m³ for the same 80 × 80 at 180 cm. That is a good ten percent more buffer on exactly the same floor.

Where you notice it: in the temperature swing between day and night, and in how often your fan has to intervene. A slower tent is easier to control, and a climate controller that switches less often holds your average closer to your setting.

It is also why you should look at height when comparing tents rather than floor area alone. Two 0.64 m² tents are not the same product.

Frequently asked questions

How is that 1.28 m³ arrived at?
Floor area times height, so 0.64 m² × 2.00 m. It is the gross volume, before subtracting your equipment.

Does more volume mean I can extract less?
No. Your extraction scales with volume rather than against it. What you gain is stability: the temperature moves more slowly.

Is this size enough for a full cycle?
Yes, 0.64 m² with 200 cm of height is a common size to work from cutting to harvest in.
