Hydrobuilder 2' x 4' Grow Tent Setup Guide

Tent Setup

Be sure to carefully measure the space you intend to setup the tent in. It should be slightly larger than the tent itself to allow for an easy setup. You should also plan your ventilation setup as you will want room on one or more sides of the tent for ducting. We give some examples of ventilation setups below.

You should have a space available at least this size:

  • 2ft wide X 4ft deep X 7ft Tall

Setting up the tent is a simple.
Just follow the included instructions.
You can review them here.

Choose a Growing Media/Method:

Depending on your intended use of this tent, you can choose from the following growing methods available at Hydrobuilder:

Choose a Lighting Setup

Depending on your intended use of this tent, you can choose from a wide range of lighting styles. LED Lighting is recommended for it's superior performance and longevity, while HID Lighting will have a cheaper up-front cost and will produce more heat. Flourescent lighting is preferred in hight heat applications as fluorescent tubes give off very little heat. No matter what lighting style you choose, adjustable light hangers are recommended to give you more control over the height of the lighting throughout the stages of growth.

View Our Lighting Options:

Choose a Ventilation Setup

Proper ventilation is essential to healthy plant growth. You should replace the air in your tent at least once every 5 minutes when the lights are on. We recommend the following minimum CFM rating for your ventilation setup. Please note that CFM performance of a fan is affected by the length and path of ducting and obstructions like a carbon filter. A higher performance fan than you need is preferred and can be controlled using a variable fan speed controller.

  • Grow Tent Volume: 2ft x 4ft x 7 ft = 56 cubic feet
  • Recommended Fan CFM: 182+ CFM

You should also pair a filter with your ventilation to help clean the air and remove odors. We recommend using a standard carbon filter as they are easy to use and provide ample air and odor filtration for grow tents. View our Carbon Filter options here

Connecting your filter to your fan is easy, just grab some ducting and clamps. We carry a range of options that can be found here: View ducting components

Your ventilation can be set up in a number of ways. Here are some possible configurations:

What you will still need:

To get up and running you will need a few more things, mainly a growing container/media setup, plants, water, and nutrients. We covered the growing setup choices above, for nutrients we offer a wide selection from all of the industry leaders. View our selection of nutrients.

If this is your first time growing, and aren't sure where to start, we recommend sticking with soil and containers. It's the easiest to learn with as the soil is more forgiving, allowing you to make small mistakes with nutrition that would otherwise cause issues in hydroponic systems. It's also really cheap and easy to setup. If you choose this route, the Fox Farm Trio Soil is a great nutrient starter kit to use. If you'd like a more advanced nutrient plan that includes micronutrients then The Dirty Dozen kit by Fox Farm is the one we recommend.

If you have any questions about your tent setup or component installation please give us a call, we are happy to help you get started! You can reach us at 888-815-9763, Monday thru Friday, 8am - 5pm PST.

Customer Reviews

2x4 Hb tent Review by Billy Bob
Great quality material, nice amount of ports. Wish the seams were doubled up a bit better. A few minor light leaks.

The fact that it is actually 27 x 5 is great too. 2x4 equipment actually fits inside and it adds a little over 2 sq ft of space.

First tent Review by Corals
This is my first tent. It was extremely easy to build, all of the parts are labeled so you know which part goes to which part. And the instructions are also extremely easy to read.
Very reflective on the inside, and very thick canvas which is very important, especially now that winter is going to be here in California really cold and for a really good while.
I could have purchased a gorilla tent, but because I didn't I had enough left over money to buy a new light system which hung inside really nice.

Love this tent! Review by WashingtonDude
I used to grow in my closet, but I decided to get a grow tent. I purchased this one for a great price with free shipping and it arrives very quick. Easy to assemble and its really nice to have my garden in a clean environment and I have already noticed it is much easier to manage my humidity and heat in the tent.
