Hydrobuilder 4' 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:

  • 4ft 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: 4ft x 4ft x 7 ft = 112 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

Hydrobuilder rocks Review by K. Rock
This is a great tent for the value. Material is well made and design is well thought out. But as usual, what makes this purchase a no brainier is knowing that the good people at Hydrobuilder stand behind their product and deliver top-notch customer support .Case in point, a couple weeks after buying this tent it went on sale. One quick email later and I had the difference credited to my account. Super easy! It's nice to know there's still good companies out there.

Excellent product at a good price! Review by Dodger
Very well-made grow tent. Zippers and materials are sturdy and the frame easily supports the weight of a large led light and more. Easy to set up and take down. I would definitely buy another or recommend to a friend.

Great full cycle tent Review by Derek
I have used this tent for three cycles and I could not be happier. I almost decided to go with the GGT but I am happy I went with this one. For the price, it is a great deal. I use if from veg to flower and it's large enough to fit 4 large plants in my under current solo 8 gallon. does a good job sealing the light out and smell has not been an issue.
