Why Use a Grow Tent?

Grow tents are a great option for modern day growers.

Not only do they allow you to create an ideal environment for growing cannabis, but they're also easier to set up and much more user-friendly than a traditional garden.

Now while  apartment dwellers can just line their closet with foil, throw up some lights and grow herb, it’s not going to produce the best buds possible.

Grow tents allow you to completely control the humidity, temperature and light—all of which are vital to growing marijuana.

Even if you don’t live in an apartment, growing outdoors is risky.

A lot of us may live in a legal state now, but that’s not going to stop someone from jumping your fence to steal your hard work.

It also allows for maneuverability.

If you move, you can load up your grow tent and move shop.

How to Pick Your Tent

There’s not really much to a grow tent, but there are a few things you want to acquaint yourself first before you buy one.

  • Dimensions

You’re going to want purchase a size that will work with the amount of area you have, while also taking account how many plants you want to grow.

Measured in feet or inches, you can get grow tents in various sizes from 2’x2’x4’ to massive tents that are 8’x6’x7’.

  • Light-proof

To control the environment perfectly, you need the tent to be light-proof.

This is also a discretion concern.

If you’re trying to grow without anyone knowing (which you should always be doing) then you don’t want light to be shining through your tent.

And you don't want light sneaking in to mess up your plants flowering stage.​

  • Reflection

This is usually shown as a percentage, and it’s used to demonstrate how reflective the inside of the tent is.

You want high reflection so that light can reach even your bottom buds.

Plus, it helps conserve energy and requires you to use less light to achieve more results.

The old school way has always been foil or white paper, but grow tents use materials like Mylar.

  • Ventilation 

True, you can get ventilation with a regular fan or even opening up the tent, but that’s not what we're going for.

We want to create an optimal environment.

To do this, you need a grow tent with plenty of ways to set up your exhaust fans.

  • Metal-Frame

Grow tent frames come in many forms.

The best, however, are going to be metal.

You need a frame that will stand up to the weights of all your lights and ventilation system.

  • Heavy-Duty Zipper

If you get a grow tent with a janky zipper, it’s going to be hard to maintain the environment.

You’ll have light leaks, air leaks and not to mention smell leaks.

Zippers are something you want to make sure the manufacturer isn’t being cheap about.

What Should Come in a Pre-Built Package?

To put it simply: everything you need to grow.

Here is a quick run down of the minimum you should expect from a complete grow tent package:

  • Grow Tent
  • Grow Light, Full Spectrum
  • Inline Exhaust Fan
  • Carbon Filter
  • Fan Speed Controller
  • Clip Fan (circulation fan)
  • Heavy Duty Light Hangers
  • Thermo-Hygrometer (monitors temperature and humidity)
  • Digital Timer

Some kits even go so far as to give you pots, soil and nutrients.

And, some hydroponic specific kits give you everything for the hydro set up too.

The larger the kit, the larger the price tag, though.

Also, you don’t need to buy a kit—everything you need can be bought piece by piece.

If you go this route you have a little bit more control over what goes in the tent and you don’t have to cough up a large lump sum to get started.

You can buy the essentials and then slowly add to the tent and upgrade your equipment.

How Should you Set Your Tent Up

You'll want to bookmark this page and use this brief overview on setting up your grow tent.

Keep in mind, grow tent setup starts before you even buy your tent.

You need to plan where you’re going to place the tent in your home, and make sure that you have plenty of room to run ducting.

This means you can’t cram a grow tent in an area that’s just big enough to hold it.

Assemble the Tent

Every grow tent is different, but in general the assembly is this:

  • Connect the frame work together
  • Pull the canvas over the frame and zip it up
  • Place the floor tray in the bottom of the tent
  • Fit the ceiling hanging bars inside the tent

Once you have the tent put together, you can now move on to the fun stuff.

Lighting Setup

You’re going to want a light that can provide enough light for the square footage of your grow tent.

The formula for lumens per sq ft

Square Footage of Your Canopy Area (at plant per 4 square foot)

x

2000 lumens = Required lumens for your area

The formula for watts per sq ft

Square Footage of Your Canopy Area (at plant per 4 square foot)

x

32 watts = Required wattage for your area

Ideally, your grow tents hanging bars will be adjustable.

This is because you want the lights to only be about 6-12” away from your cannabis at any given time.

If they are too far away from your plants, they will stretch out to far trying too reach for the light source.

To set your lights up in your grow tent:

  • Check to make sure the plug is properly grounded and the correct voltage.
  • Decide on the cord ports you will use.
  • Hang the light on the crossbar and adjust it to the correct height.
  • Set your timer up with the correct “on” and “off” times (24 hr light for veg 12/12 for flower) and plug the timer into the socket.
  • Pull the lamp cord through the grow tent port and plug the light into the timer.

Ventilation Setup

You need to be providing fresh air to your plants if you want them to grow up healthy.

But it goes beyond that:

You need to provide proper filtration to make sure you’re giving them clean air AND killing the odor.

Your tents air should be replaced at least every 5 minutes that the lights are on.

Not only to bring in the fresh air but also to replenish CO2.

The equation can get a little complicated when it comes to ventilation.

Because CFM can be affected by so many variables like the lengths of the duct and even its path.

CFM - This refers to the amount of cubic feet per minute your fan can move.

So, to replace the air every five minutes you need your CFM needs to equal the volume of your grow tent divided by 5.

(LxWxH)/5=CFM

If your grow tent is 4x4x4 it has a volume of 64 feet.

Divide 64 by 5, and you get 12.8—anything less than this and your will be doing your garden a huge disservice.

Keep in mind, this is the bare minimum, and many growers opt for every 3 minutes all the way to 3-5 times PER minute.

The set up can be done in a number of different ways.

Here are a couple of examples

If one of your top priorities is dealing with the smell of your garden, then running both the filter and fan inside the tent will work best.

But if you want more room inside the tent, or your grow tent doesn’t have the structures in place to run them inside, you can run them both on the outside of your tent with just duct running out of your tent.

Again, it’s all just what works best for YOU.

How Many Plants in a 3x3 Grow Tent?

Ideally, you want to give each plant about 4 sq ft.

This, however, is not always feasible.

Especially when you’re growing in a grow tent that is only 3'x3'.

If you did, you’d only be able to grow two plants.

But growing in a tent, you’re able to get away with a little less space per plant.

In a 3x3 grow tent you can grow at max 4 plants in rows of two.

Putting four in the tent will hinder their size, though.

So, ultimately, it will depend on if you'd rather grow two large plants or four medium-size plants.

We recommend testing both these methods and seeing which one yields more cannabis.

How Many Plants Can I Legally Grow?

You don’t want to get caught not knowing the law, and, even though growing cannabis is legal in quite a few states, there is still strict regulations surrounding it.

And another thing, even though you can legally obtain cannabis in 28 states, there is only a few you can grow in.

So, please, don’t just assume that if you can carry or smoke marijuana that you can legally grow it.

Here are the states and a brief rundown of how many you can grow in your grow tent:

Washington D.C - Every medical marijuana patient is entitled to grow up to 15 plants each.

California - You can possess no more than six plants regardless of their stage in the growing process.

Colorado - Up to six plants are allowed per Colorado resident over age 21, with as many as three plants flowering at one time.

Alaska - Six plants growing at a time with no more than half flowering at the same time.

Oregon - It doesn't matter what stage they are you’re allowed four plants per home, total.

Sadly, if you’re not in one of these states, you can’t legally grow your own cannabis!

How to Keep Grow Tent Cool?

Since your grow tent in an enclosed area, you might have a problem keeping it cool.

And if you have any experience growing in a tent, you know it can be a challenge to keep it cool.

  • Run your lights at night - Since the temperature in your grow tent is going to be influenced by the temperature outside the tent, run your lamps (which permeate heat) at night when it’s cooler outside.
  • Turn half your lights off - If you’re experiencing a temporary heat wave, you can use this method to simulate an overcast day in your grow tent—a much better alternative to scorching your plants.
  • Try adding A/C - There are plenty of portable A/C units that can fit in your grow tent. If you live in the south or other hot areas, during the summer this may be your only option. Remember, you can’t cool hot air with more hot air.
  • Point a fan on your light - This can help keep the light cooler, which is the primary source of heat.

Another way to keep your grow tent cool is bringing the air in through ice.

Sounds messy, I know, but It’s a quick fix that is easy to set up.

You can get the run down in this video:

When deciding which grow tent to put at the top of our list, we took a lot of factors into consideration.

Including quality, specs and price.

While the Apollo Grow Tent might not be the best in every category, it’s solid in them all.

Plus, with Apollo, you're getting a brand name that it known in the growing space for quality products including lights, charcoal filters and inline fans.

As far as the tent goes, you couldn’t ask for a better starter grow tent that.

It has a durable metal frame and thick fabric that’s double stitched to prevent any light leaks or climate leaks.

The Apollo Grow Tent is lined with a mylar film that is not only highly reflective but also 100% light proof and tear-proof.

They guarantee 92-97% reflection from your grow lights which saves energy while also getting light to the backside of your buds.

The kit also includes a removable mylar floor tray and a couple of filter straps.

The zippers are thick and heavy-duty, but not as airtight as you’d hope.

If you look closely, you might see some light leaking through them.

Although not enough to spot the tent in a dark room.

One of the best aspects of this tent is how customizable it is.

With a bunch of six-inch ports, a few two-inch ports and three screened Velcro sealable openings you can hook up any number of fans, filters and lights.

And the frame is sturdy enough to handle a couple of lights and a couple of fans—maybe even more.

Overall, this tent is a great deal for anyone looking to delve into the world of grow tents.

Pros

  • Portable
  • Plenty of customizable portals
  • Thick, tear-proof material
  • Available in many sizes (can grow around 6 plants in the 48”x48”)

Cons

  • Light leaks through zippers slightly
