Best 4x4 Grow Tent Kit: What's Included

A 4x4 kit bundles the tent, light, exhaust fan, carbon filter and a controller in one box. That saves a lot of decisions, but the kits differ more than their photos suggest: the light can be 400 or 450 watts, the tent frame can carry 150 or 250 pounds, and one kit ships without a circulation fan.

Start with the light

The light decides how much you can grow, so it is the first thing to compare. THCFarmer’s member data puts the typical flowering draw for a full 4x4 at about 430–500 W, with a median of 480 W.

• Spider Farmer SF4000: 450 W, rated PPF 1,171 µmol/s and 2.7 µmol/J by Spider Farmer, 4x4 flowering and 5x5 vegetative coverage. The 2026 version uses Bridgelux diodes and has not been independently measured yet. More in our 4x4 grow light guide.
• AC Infinity IONBOARD S44: 400 W. The retailer listing describes it as a 4x4 board; we could not find a published PPF for it.
• Vivosun LumaLight 400W: 400 W, IP65, rated for 4x4 coverage. Vivosun lists a PPFD of 967 µmol/m²/s at 12 inches, which is a single-point figure, not a canopy average.

With 400 W in a 4x4, expect the edges to be dimmer than with 450–500 W. You can confirm the math for your target light level with our grow light calculator.

Then the tent

The frame carries the light, filter and fan, so pole size and rated load matter.

• AC Infinity CLOUDLAB 844: 22 mm steel poles, 250 lb beam capacity, Oxford outer with Mylar lining, four 4-inch and five 8-inch duct openings, and a 13.8 × 47.2 in viewing window.
• Vivosun standard tent (in the kit): 1680D canvas, 16 mm poles, 150 lb load-bearing. Vivosun sells a heavier “Pro” tent separately with 22 mm poles; the kit uses the standard one.
• Spider Farmer (in the kit): 4×4×6.5 ft. Spider Farmer’s kit page lists a 1680D Oxford exterior for its black-tent kits; the listing does not state pole size.

Our best grow tent guide compares stand-alone 4x4 tents if you would rather buy the tent separately.

Ventilation and control

All three include a 6-inch fan and 6-inch carbon filter, which is the right size for a 4x4 by LONGWELL’s sizing formulas (about 190–200 CFM needed with a filter and a typical duct run).

• AC Infinity includes an EC inline fan and its CONTROLLER 69 PRO, which runs the fan, clip fan and light from one unit.
• Vivosun lists the R6 at 390 CFM, 45 dBA and 70 W, controlled by the GrowHub A22 with two outlets and a temperature/humidity sensor. One bullet on Vivosun’s page mentions an “R4” fan while the included-items list and spec table say R6; confirm on your order.
• Spider Farmer includes its GGS controller kit and adds a soil sensor that reports moisture, temperature and EC.

Size the fan for your own room with the fan CFM calculator, and see the inline fan guide for upgrades.

What every kit leaves out

• Humidity control. No kit includes a dehumidifier. If your room is humid, budget for one; see dehumidifiers for grow tents.
• A pH meter, if you will feed with nutrients or grow hydroponically. See pH meters.
• A circulation fan in the Vivosun kit. Vivosun recommends two AeroWave E6 clip fans as add-ons.
• Timers and power strips beyond what the controller provides. The Vivosun A22 has two outlets.

Warranty fine print

• Spider Farmer lists 5 years on SF series lights, with full coverage in year 1 and paid parts shipping or a discounted replacement in years 2–5. GGS controllers get 2 years and grow tents 1 year.
• AC Infinity covers its products for 2 years from purchase.
• Vivosun’s policy (effective January 1, 2026) gives grow tents 2 years, LumaLight lights 2 years unlimited plus a 3-year limited extension, and treats filters, ducting and pre-filters as consumables with no warranty. Claims are only handled by Vivosun for purchases from its own site or official Amazon, eBay and Walmart storefronts.

Comparing the real cost

TheOneGrow suggests a simple method: for each option, add the kit price, everything it is missing, delivery and tax, and first-cycle supplies. Count a voucher only if it applies to things you would buy anyway. We don’t list prices here because they change constantly; the “Check price” links open each seller’s current listing.

How these picks were made

We compared each kit’s listed contents against what a 4x4 needs: a light in the commonly used wattage range, a 6-inch exhaust with filter, a frame strong enough to hold it all, and controls. We did not test any of these kits ourselves; see how we research. If you are deciding between the brands’ wider ecosystems, read Vivosun vs AC Infinity and Spider Farmer vs AC Infinity.
