Best 4×4 Grow Tent Kit: The Essentials For Your Setup

If you expect consistently healthy yields for your plants, it’s essential to invest in the right kit. Cutting corners will only result in frustration and meagre harvests. In this section we’ll look at everything you need to need to create your own grow tent setup.

The Tent

The grow tent does more than just provide discretion when growing cannabis at home (although, yeah, it does that too).

It also allows you to create a managed environment that’s more conducive to growing than letting your crops grow in the open air. A tent is a contained environment which puts you in control of all the variables.

A 4×4 tent allows you more than enough space to grow without impinging too much on your home environment.

When choosing a tent, the right materials are very important. Both for the interior and exterior. The exterior needs to be durable, with double seams and robust zippers. It’s a good idea for the interior to be made of a reflective material like Mylar. This will allow you to increase the intensity of the light without using too much energy.

A viewing window is also essential for your tent. You don’t want to have to open the door every time you want to check on your crops.

Grow Lights

It goes without saying that your plants need access to light if they’re to grow. In the absence of sunlight (because how are you going to get that into a tent?) you’ll need a artificial light source that replicates the spectrum of lights necessary for plants to photosynthesize.

The good news is that there are all kinds of lights which will help you to grow cannabis successfully. So many, in fact, that it may be difficult to know which to choose. Any of these lights will be suitable for use in a Grow Tent;

  • T5– Fluorescent T5 Lights are energy efficient but low in intensity. However, they are most useful when starting out, Just make sure they’re positioned very close to the plants.
  • LED– Light Emitting Diodes are energy-efficient, long lasting and a great all-rounder for Grow Tents.
  • HID– High Intensity Discharge lights are similar to those seen in car headlamps. They use either high-pressure sodium or metal halide, and are appropriate for all growth stages. Take a look at some of our HID buyer’s guide.

Inline Fan

A small inline fan (also known as a duct booster fan) will be necessary to ventilate your enclosed growing space. Proper ventilation gives you more control over the temperature, humidity and moisture of your growing space. Because you’re growing in a small space, you don’t need to use a large fan. A diameter of 6 inches should do fine.

Hydroponics System

Your plants need water to grow. Since they won’t be getting access to rain, and watering them by hand creates way more problems than it solves, many cannabis growers use a hydroponics system to create better growing conditions and enjoy healthier yields.

There are a number of hydroponics solutions which are popular among growers. These include;

  • Flood & Drain Systems– These simple systems are often called “ebb and flow” systems, and their simplicity and ease of maintenance make them appealing for newcomers. The plant sits on top of a growing medium like rock wool or pebbles and nutrients are pumped to the plans.
  • Deep Water Culture– Another simple system these “bubble” systems are highly cost-effective making them another popular choice for new growers. Here, the plant sits atop a bucket of oxygenated water and nutrients and is supported by pebbles with the roots left hanging.
  • Drip Irrigation– This top-feeding drip system involves nutrient-rich water being pumped on top of the plant while also passing through a system of tubes to get to the roots which are supported by an appropriate growth medium.

Carbon Filter (optional)

A carbon filter isn’t absolutely necessary for indoor growing, but it can prevent odors from accumulating in your tent and permeating within your home.

If you are growing close to your living area a carbon filter is definitely worth considering. Not only will it stop your home from smelling… cannabis-y, it’ll mask the smell of fertilizers, and other strong-smelling items.

For a 4×4 Grow Tent with a height of 8 feet or less (which most tents will be) you’ll need a carbon filter with a minimum 128 Cubic Feet per Minute (CFM).

Grow Tent Setup FAQ

Now that you know what you need to grow your plants indoors, you probably have some questions about how to grow effectively. After all, nobody wants to invest their money in growth equipment only to experience disappointing yields.

Here we’ll look at some Frequently Asked Questions when it comes to using a 4×4 Grow Tent.

How Many Plants Can I Grow In A 4×4 Tent?

One of the most common conundrums faced by new growers is how densely to populate their grow tents. They want robust yields, but at the same time, they don’t want to crowd them in ways that will impede their growth.

When it comes to a 4×4 Growth Tent, there are 4 growth methods, each with slightly different requirements for spacing between plants;

  • Sea of Green– 1 plant per square foot (15-16 plans)
  • Scrog– 0.25 plants per square foot (4 in all)
  • Topping– 2-4 square feet per plant (4-8 total)
  • Low-Stress Training– 2 square feet per plant (8 total)

Most growers with this kind of setups choose to grow 8-12 plants in a 4×4 tent. These are not small grow tents, you can grow as many as 16 and as few as 4, 8-12 hits the “sweet spot” between decent yields and giving the plants space to grow.

How Do I Set Up Proper Grow Tent Ventilation?

We’ve already discussed the importance of an inline fan to ventilate your Grow Tent. But how do you set it up to get the results you need?

When setting up your ventilation, it’s crucial to keep in mind why your growing space needs to be ventilated in the first place.

This is to control the humidity, regulate the temperature, ensure that there is enough carbon dioxide in the tent for the plants to grow, and to keep pests and diseases away from your crops. Creating a breeze inside your tent will also help the plants to grow strong stems.

This is why inline fans are far more effective than oscillating desk fans. They extract oily or humid air from within the tent and bring in fresh air, helping to keep your plants from impurities.

Hang your inline fan on the top crossbar and set it to runs once every 5 minutes. This will help you to get the right air circulation inside the tent, while also preventing the fan from interfering with the plants’ growth.

You can make your fan more effective and prevent it from overworking by using an intake hole that’s around 4 times the size of the exhaust hole (passive intake).

However, if you’re using a fan for blowing air in and out of the tent (active intake), it doesn’t matter what size the intake hole is.

What’s The Perfect Wattage Of Light For A 4×4 Grow Tent?

As we stated previously, light is extremely important in growing healthy plants. But while we’ve looked at the different kinds of lights available, we have yet to discuss what kind of wattage is best for use in a 4×4 Grow Tent.

Most growers find that a wattage range of 500-600W gets good results, although if you prefer to err on the side of caution, 400W is also perfectly acceptable.

Indeed, when using an inline fan and passive air intake, 400W offers a satisfactory heat : light ratio that will help to maintain good growing conditions.

What Are The Best Marijuana Strains For A 4×4 Grow Tent?

Some strains of marijuana will thrive better than others in a 4×4 Grow Tent, and you’ll need to consider which method you’re using to cultivate your plants (see above).

Some strains need more space in which to flourish than others, and choosing the wrong strain could mean that your plants battle for space.

We find that strains like Purple Haze, Madonna, Gold Leaf and Bubble Gum all maintain a fairly modest sizes throughout every stage of their growth, making them well suited for 4×4 Grow Tents.

What’s The Ideal Temperature For A 4×4 Grow Tent?

Temperature is also an important consideration when growing your plants. However, it’s difficult to advise a single optimal temperature for growing your plants as this will depend on the growing needs of the strain you’re trying to cultivate.

However, maintaining an average temperature of 70-80 degrees Fahrenheit will provide healthy growing conditions for most strains of marijuana.

What’s The Best Height For a 4×4 Grow Tent?

You’ll likely need to find some sort of balance when it comes to the height of your tent. You’ll need to contend with the logistics of your space and the needs of your plant.

If your tent is too tall, your plants may not get the access to the light that they need to grow optimally. On the other hand, if your tent is too short, you may find that by the time you’ve made room for your lights, fan and carbon filter there’s insufficient space to grow as many plants as you’d like.

By rule of thumb, we recommend a height between 5 and 7 feet for your 4×4 Grow Tent.

Final Thoughts

Growing your own marijuana is an enjoyable and rewarding pursuit. But when you’re growing indoors, it can be very difficult to know where to begin.

Stick with the answers and recommendations above, and you’ll be able to set up a highly efficient 4×4 Grow Tent that is discreet, low in energy use and conducive to consistently healthy yields.

Of course, you know where we are if you need any more advice!
