3x4 Grow Tents
3x4 grow tents provide a 12-square-foot growing footprint in a rectangular format well-suited to perpetual harvest systems and multi-chamber production setups. The 3x4 dimensions allow two distinct growing zones to share the same tent footprint with a divider panel -- a vegetative chamber on one side and a flowering chamber on the other -- making it one of the most practical configurations for continuous harvests from a small space. Covert and AC Infinity both produce 3x4 tent options at Hydrobuilder, including complete kit configurations.
Multi-Chamber 3x4 Tents
The defining application of the 3x4 grow tent is the perpetual harvest multi-chamber setup. The Covert 3x4 Multi-Chamber Grow Tent divides the 3x4 interior into separate vegetative and flowering zones, each with independent light schedules, ventilation, and environmental management. A 2x2 vegetative chamber alongside a 2x2 flowering chamber within the same tent footprint allows one chamber to complete its cycle while the next batch of vegetative plants is being prepared -- creating a rolling harvest cycle without requiring two separate tents. The Covert 3x4 is available as a bare tent or in complete kit configurations with matched LED or T5 lighting and ventilation packages.
Single-Zone 3x4 Use
Used as a single-zone tent, the 3x4 accommodates a single 400-600W LED or CMH fixture covering 6-12 plants depending on container size and training method. Browse all grow tents including Gorilla Grow Tents and complete grow tent packages matched by tent size. Fast shipping.
3x4 Grow Tent FAQ
What is a perpetual harvest setup and how does a 3x4 tent support it?
A perpetual harvest system staggers plant cycles so that one set of plants is always at or near harvest while another is in an earlier stage -- eliminating the downtime between grow cycles that comes with single-stage growing. A 3x4 multi-chamber tent makes this possible in a compact footprint by providing two independently controlled chambers in the same tent: a vegetative chamber (typically 2x2) on one side and a flowering chamber (2x2) on the other, each with its own light schedule, temperature, and humidity management. When the flowering chamber is harvested, the vegetative plants move over, and a new batch goes into the vegetative side.
What size light do I need for a 3x4 grow tent?
For a single-zone 3x4 tent used for flowering, a 400-600W LED or 315W CMH provides adequate coverage across the 12-square-foot footprint. A 400W LED at mid-range efficiency covers 3x4 at moderate flowering intensity; a 600W or 630W CMH covers it at high intensity appropriate for demanding flowering varieties. For the 2x2 individual chambers in a multi-chamber 3x4 setup, size each chamber independently -- a 200-300W LED or single 315W CMH per 2x2 chamber is the standard configuration.

What ventilation do I need for a 3x4 grow tent?
Calculate tent volume: 3 x 4 x height (typically 6-7 ft) = 72-84 cubic feet. For a single-zone tent, an inline fan moving 72-100 CFM exchanges the volume once per minute -- the minimum for temperature and CO2 management. Add 25-30% capacity for carbon filter resistance, bringing the recommended fan to 100-130 CFM. For multi-chamber setups, each chamber requires independent ventilation -- smaller inline fans (4-inch, 100-150 CFM) per chamber are the standard approach rather than one large fan serving both zones.
