| Tent Size | Floor Area | Plants (Medium) | Recommended Light | Fan Size |
|---|---|---|---|---|
| 2×2 ft | 4 ft² | 1–2 | 100–150W | 4-inch |
| 2×4 ft | 8 ft² | 2–3 | 200–250W | 4-inch |
| 3×3 ft | 9 ft² | 2–4 | 250–300W | 4-inch |
| 4×4 ft ⭐ | 16 ft² | 4–6 | 400–500W | 6-inch |
| 5×5 ft | 25 ft² | 6–9 | 500–650W | 6-inch |
| 4×8 ft | 32 ft² | 8–12 | 600–800W | 6-inch |
The 4×4 ft tent is the best starting point for most Canadian home growers. It fits comfortably in a closet or spare room corner, supports 4–6 medium plants, runs efficiently on a 400–500W LED, and produces meaningful yields year-round regardless of what's happening outside. It's also the most common tent size, so there's a huge amount of community knowledge and gear designed specifically for it. If space is tight, the 3×3 is an excellent smaller alternative.
A 4×4 ft tent (16 sq ft) can comfortably fit 4–6 medium plants growing in soil, or up to 9–16 plants in a Sea of Green (SOG) setup. For larger indeterminate tomatoes or heavily trained photoperiod plants, 4 plants is ideal. Autoflowering varieties can be packed more tightly — 6–9 is achievable. Always leave room for airflow between plants to prevent humidity pockets and mould, which is especially important in humid Canadian summers.
AC Infinity tents are the better-built option — thicker 2000D canvas, stronger pole systems, better zippers, and integrated cord management. They also have Canadian warehouses for faster shipping and better warranty support. Vivosun tents are significantly cheaper and perfectly functional for beginners — a good choice if budget is the main constraint. Both ship reliably to Canada. If you're setting up a long-term grow room, AC Infinity is worth the extra investment. For a first tent on a budget, Vivosun delivers solid value.
As a rule of thumb: 4-inch inline fans suit tents up to 3×3 ft, and 6-inch fans are ideal for 4×4 ft and larger. You want to exchange the air in your tent every 1–3 minutes. A 4×4×6.5 ft tent holds roughly 104 cubic feet of air — a 6-inch fan rated at 400+ CFM handles this comfortably. The AC Infinity CLOUDLINE series is the most popular choice for Canadian tent growers because of its smart speed controller and near-silent operation.
Yes — grow tents are actually easier to manage in Canadian winters because cold, dry outdoor air helps with temperature and humidity control. Your main challenge in winter is humidity being too low (VPD too high) due to heated indoor air. A humidifier is typically needed from October through April in most Canadian provinces. In summer, the opposite applies — outdoor humidity raises tent RH and a dehumidifier becomes important, especially during flowering. Year-round indoor growing is one of the biggest advantages Canadian indoor growers have over outdoor gardeners.
Tent size is just the start — dial in your light, VPD, and PPFD too.
