Description

VIVOSUN Starter Grow Tent Kit 4x4 - Happy Hydro

Your first real indoor grow room,
picked out and packed in one box so you can skip the guesswork

The VIVOSUN Starter Grow Tent Kit 4 x 4ft is built for people who have never run a grow tent and do not want to spend a weekend researching parts. You get a 48 by 48 by 80-inch tent, a 400W full-spectrum LumaLight, a 6-inch inline fan with a carbon filter and ducting, and the GrowHub A22 controller that reads your temperature and humidity and switches the fan on and off for you over WiFi. Everything is sized to match, so there is nothing to calculate. Hang the light, connect the fan to the A22, download the Vivosun app, and start growing up to eight plants.

Full-spectrum LED, 967 PPFD WiFi temp and humidity sensor Everything matched in one box
Free shipping on orders over $49
30-day returns on all orders
Serving growers since 2006
Why a kit
Buying parts one at a time vs. the Starter Kit
Buying parts separately
  • Guess which light and fan match a 4x4 tent
  • Order a filter and ducting that may not fit the fan
  • Buy a separate timer and outlet just to automate
  • Check the tent by hand and hope the numbers are right
  • Hunt for grow bags, trellis, and shears on top of it all
  • Pay shipping on five or six separate boxes
Starter Grow Tent Kit
  • 400W light and 6-inch fan already sized for 4x4
  • Matching carbon filter, ducting, and clamps included
  • GrowHub A22 automates the fan by temp and humidity
  • Sensor probe reads your tent and alerts your phone
  • Grow bags, trellis net, and shears come in the box
  • One order, one setup, priced for a first grow
What makes it different
Everything a 4x4 grow needs, matched and ready

GrowHub A22 watches your tent for you Temp + humidity

The A22 reads your grow with a temperature and humidity probe and switches the fan on and off to hold your range. Plug in over 2.4G WiFi, set your targets in the Vivosun app, and get an alert on your phone when something drifts. It keeps running on its own schedule even if the WiFi drops.

400W full-spectrum LumaLight

The light carries 3000K, 5000K, 660nm, and 730nm diodes for a full spectrum from seedling to harvest, putting out 967 PPFD at 12 inches. Dim it to 25, 50, 75, or 100 percent by hand, through the A22, or in the app.

6-inch fan, filter, and ducting

The R6 inline fan moves up to 390 CFM at around 45 dBA, paired with a 1200+ IAV carbon filter and 8 feet of ducting to pull heat and odor out of the tent. All of it is sized for a 4x4 space out of the box.

Sturdy 600D tent that blocks light

The 48 by 48 by 80-inch tent uses 600D fabric over 16mm poles rated to 100 pounds, with an aluminum reflective liner and a viewing window. Multiple duct ports up to 8 inches give you room to route the fan and cords cleanly.

Two outlets and two USB ports

The A22 gives you two switched outlets rated to a total of 15A and two USB ports, so you can add a clip fan, humidifier, or heat mat later and fold them into the same schedule and triggers without buying another controller.

Grow accessories included

Five 5-gallon grow bags, a 4 by 4ft trellis net, pruning shears, rope hangers, and hanging straps come in the box, so the day it arrives you have what you need to plant and support up to eight plants.

From box to first grow, in four steps

1

Build the tent

Assemble the 4x4 tent with no tools, then hang the light and mount the fan and filter using the included straps and clamps.

2

Plug into the A22

Connect the inline fan to the GrowHub A22, place the sensor probe near your canopy, and plug the controller into a wall outlet.

3

Set your targets in the app

Pair the A22 to the Vivosun app over WiFi and set the temperature and humidity range you want. The fan then runs on those triggers.

4

Plant and check in

Fill the grow bags, start your plants, and watch conditions from your phone. Adjust the light and get alerts when readings drift.

Questions
Frequently asked questions
Yes. This kit is put together for first-time growers on a budget. The light and fan are already matched to the 4x4 tent, so you do not have to size anything, and the GrowHub A22 handles the fan for you based on temperature and humidity. You assemble the tent, hang the light, plug the fan into the A22, and follow the app.
The A22 is a WiFi outlet controller with a temperature and humidity sensor probe. In this kit it runs the inline fan, turning it on and off to hold the range you set. It has two outlets rated to 15A total and two USB ports, so you can add a clip fan, humidifier, or heat mat and control those from the same app. It also keeps running on a local schedule if your WiFi drops.
VIVOSUN rates the 36 by 36-inch tent for two to four plants in 3-gallon pots. Most first-time growers run three comfortably with the included 5-gallon grow bags and trellis net. If you want to keep it simple with one or two larger plants, that works well in this footprint too.
The 6-inch R6 fan moves up to 390 CFM and pulls air through the included 1200+ IAV carbon filter, which scrubs odor before the air leaves the tent, while the ducting carries heat away. Running the fan through the A22 lets it react to your readings, so it ramps up when the tent warms and eases off when things are stable, at around 45 dBA.
The Starter kit uses the GrowHub A22, a simpler plug-based WiFi controller that switches devices on and off by temperature and humidity. The Pro kits use the E42A and up, which add features like direct fan speed control and VPD targeting. For a first grow the A22 covers what you need, and you can step up to a more advanced controller later without replacing the tent, light, or fan.
The kit includes the tent, light, fan, filter, ducting, controller, grow bags, trellis, and shears. You supply your growing medium, nutrients, and the plants or seeds themselves. A smartphone is recommended so you can pair the A22 and use the app. If you want a starter shopping list for medium and nutrients, call us and we will put one together.
If you receive a defective or damaged unit, email us a photo at help@happyhydro.com and we'll take care of you. For change-of-mind returns, we accept returns within 30 days for most items in new, resalable condition. If you're not sure whether this product is right for your setup, call us first at 716-217-0353. We'd rather answer your questions before you order.
