How To Build A DIY Cannabis Grow Tent In Just 3 Steps!

Want to grow your own weed? DIY grow tents are easy to build and give you complete control over your plants’ growing environment so you can produce top-tier bud!

Looking for a simple, cost-effective setup for growing your own weed? Below, we’ll walk you through the simple process of building your own grow tent for a fraction of the price of a store-bought tent/box.

WHY BUILD A DIY GROW TENT?

Growing your own weed is a great experience. Germinating your seeds and watching them grow into healthy plants with big, aromatic buds is a great way to develop a deeper connection with this ancient plant. Not to mention, you’ll likely end up with a far superior product than what you’re able to score elsewhere.

Unfortunately, not everyone has enough space to grow plants outdoors under the sun. That’s where a DIY grow tent comes in; for many people, a homemade grow tent proves to be the most cost-effective and efficient setup. While small grow tents are pretty cheap, you can build your own tent for next-to-nothing if you take the time to hunt around for supplies. Plus, they allow you complete control over your plants’ growing environment and produce a great harvest every time!

IMPORTANT CONSIDERATIONS FOR YOUR DIY GROW TENT

Before you start looking around for building materials, take a few minutes to reflect on these important considerations for your tent:

LIGHTPROOF

Cannabis plants need well-defined light and dark periods in order to flower properly. Light leaks during dark hours can stress photoperiod strains, stunting their growth, interrupting their flowering, or even triggering hermaphroditism. Even autoflowering strains are believed to rely on consistent dark hours for respiration, photosynthesis, and more. Hence, your DIY tent must be lightproof.

WATERPROOF

Cannabis needs regular watering and feeding. Make sure your tent is waterproof so runoff or spills don’t cause any damage to the area around your tent.

AIRFLOW

Cannabis plants need proper airflow to grow properly. Poor airflow, on the other hand, can create hot spots in your tent that trap heat and humidity, creating a breeding ground for bacteria and attracting pests. Your tent needs to be well-ventilated to prevent these problems.

The size of your grow tent will vary depending on the amount of space you have available, your budget, and how many plants you plan on growing. A 1 x 1m tent is arguably the most common size used by hobby growers, but you can go bigger or smaller than that based on your needs. Just know that if you want your plants to reach their full potential, your tent will need to be at least 1.5–2m tall to give them enough space to grow and prevent them from getting too close to your lights.

WHAT DO YOU NEED TO BUILD A DIY GROW TENT?

Building your own tent is surprisingly simple. Here’s a list of everything you’ll need:

MATERIALS

19mm PVC pipes are sturdy, cheap, and ideal for creating the frame of your tent. You’ll need:

• 16x straight pipes for the verticals and horizontals (the length of pipe will vary depending on how large you want your tent to be)
• 8x 90-degree corner fittings
• 4x t-fittings
• 1x cross fittings

PANDA FILM

Panda Film works great as the walls of your tent. Remember to use the black side of the film on the outside to absorb light, and the white side on the inside to reflect it.

LED GROW LIGHT

There are many different grow lights on the market, but we recommend LEDs for their energy efficiency and durability. HID lights are cheaper than LEDs and can produce great results, but they’ll need replacing after two harvests and use a lot of energy.

There are plenty of fans on the market. If you’re building a large tent for big harvests, we recommend using a fan and carbon filter to eliminate the odour from your plants. If you’re building a tent to grow just a few plants, a regular wall fan will do fine.

TOOLS

Once you’ve got your materials, you’ll need the following tools for the assembly of your tent:

• Duct tape (to create the Panda Film covering for your tent)
• Hand saw (in case you need to cut any of your PVC pipes to size)
• Velcro (for the opening of your tent)

HOW TO SET UP YOUR DIY GROW TENT

Now that you’ve got your materials and tools, follow these steps to build your very own cannabis grow tent in less than a day:

STEP 1: ASSEMBLING THE FRAME

If you weren’t able to buy your PVC in the size you need, cut it to size using a hand saw. Whatever size tent you’re building, you’ll need 16 straight pieces of pipe; 4 for the verticals (which should be at least 1.5m long), 4 for the base, and 8 for the roof of your tent.

Once you’ve got your straight pieces of pipe cut to size, use the fittings to connect them and build the frame of your tent. Keep in mind that your roof should have a cross fitting in the middle for extra stability to hold your light, fan, etc.

STEP 2: COVERING YOUR TENT

You’ll need to cover your tent twice; once with the white panda film for the inside of the tent, and again with black film for the outside.

The easiest way to do this is to start with the walls; tightly wrap a single piece of film around 3 of the 4 walls (the 4th will be the opening of the tent). Secure the film to the PVC pipes where your opening will be.

Next, cover the roof of your tent with another piece of film. Make sure there’s at least 3–5cm of overlap on every wall, and stick the sides down with duct tape. Step inside your tent, look for light leaks, and cover them using duct tape from the outside.

Finally, for the opening of your tent, cut a piece of film long enough to run from the middle of the roof to the floor. Secure it to the roof of your tent using duct tape and to the PVC frame on the side and bottom using Velcro.

STEP 3: INSTALLING YOUR LIGHT AND FAN

Install your grow light to the top of your tent according to the instructions that came from the manufacturer. Remember to pull the power cord out through a small opening in the roof and seal the sides with duct tape to avoid light leakage.

Finally, sit your fan on the floor, and you’re done!

How to Grow Weed on a Budget: Indoors and Outdoors

Growing cannabis doesn’t have to be a huge investment. With the right tips, you can reduce the cost of your cannabis grow room/garden and grow top-shelf weed on a budget.

Explore our in-depth guide to growing weed on a budget.

Growing cannabis on a budget can seem outright impossible to the uninformed. The cost of setting up and running a grow room, plus feeding and caring for your plants, can easily seem out of reach for the hobby grower. However, there are, in fact, many ways you can reduce the cost of your next grow-op to suit your financial constraints. In this article, we share our top tips for growing cannabis on a budget, both indoors and outdoors.

General Money-Saving Tips for Cannabis Growing

Cutting the costs for your next grow can be a lot easier than it might seem. Below are a few simple tips to help you save money when growing weed, indoors or out.

Choose Your Seeds Wisely

While it might seem counterintuitive to buy seeds when you’ve got the chance to grow bagseed for free, investing in quality cannabis seeds from the get-go has the potential to save you money (and stress) in the long-run.

When you buy seeds from a respected seed bank, you’re paying for guaranteed quality. Established seed banks have teams of dedicated breeders and growers constantly working to improve their genetics. That means, after germinating your seeds, you can rest assured the plants in your garden will grow strong and healthy (given the right care, of course) and reward you with good yields of top-shelf bud.

Buying autoflowering seeds is another great way to save money. Today’s auto strains have the potential to produce great yields and excellent buds, with the potency and flavours to stand up to any photoperiod strain. If you’re a budget grower, make sure to go auto for your next grow.

Grow From Clones

The cost of buying new seeds after every harvest can add up, especially if you’ve got a big garden and grow several plants at a time. Cloning can offset some of those costs, giving you the opportunity to reproduce your favourite strains without having to invest in new seeds every time.

Keep in mind, however, that cloning also comes at a cost. In order to get good results, you’ll want to take your clones from a robust, healthy mother plant, which you’ll need to keep in constant vegetation. Keeping a mother requires space, a constant 18/6 light cycle, and plenty of fertiliser. But, in return, you’ll get the opportunity to take numerous clones from your mother every few weeks, potentially for years to come.

Note that, over time, the yield potential of mother plants tends to go down. To deal with this, most growers renew their mother plants every 6–12 months. In general, we recommend buying seeds, keeping the healthiest plant from your seeds as a mother, and cloning it for 6 months before repeating the process. This will help ensure you’re always working with healthy plants.

Use All Parts of the Cannabis Plant

Cannabis is an amazing plant with tons of uses. Unfortunately, many growers forget that at harvest time. The stems and leaves many growers misprize post-harvest can be used to make tea, cannabutter, infused cooking oils, lotions and topicals, and much more. Make sure you hold onto these parts of the plant next time you harvest to reduce the waste of your grow-op.

Reuse and Recycle

Let’s be honest; chances are you’re going to conduct more than one cannabis grow in your lifetime. Hence, make the effort to reuse and recycle as many of the products/tools you use in your grow room as possible. Some obvious grow tools you can reuse include:

  • Pots: Unless they are broken, there is no reason you shouldn’t be able to reuse your cannabis pots for multiple grows. Just make sure you fully sanitise each container before planting a new specimen.
  • Soil: Quality soil is one of the biggest costs of a cannabis grow room/garden. Luckily, you can reuse old soil pretty easily. Just know that you’ll need to supplement some new material into your old soil to boost its nutritional value and structure.
  • Hoses, pruning shears, gardening gloves: If you’ve got gardening equipment you use for other plants, don’t go out and spend more money on extra tools for your cannabis garden. Simply sterilise your tools before each use (where necessary) to avoid spreading pests and disease from your cannabis plants to the rest of your garden, and vice versa.
  • Try composting: If you want to take things a step further and save even more, consider composting the organic waste from your house (such as vegetable scraps, paper, and cardboard). Composting is very simple and, while it takes some time, produces an excellent, nutrient-rich growing medium for your plants. Best of all, composting is virtually free. All you need is a compost bin (any old bucket, bag, or pot can work), time, and some composting worms (technically optional; composting without worms just takes a little longer).

How to Grow Cannabis Indoors on a Budget

Growing cannabis indoors is generally more expensive than growing outdoors. In order to achieve healthy plants in a room or tent, you’ll need grow lights and fans to recreate the conditions cannabis naturally flourishes in outdoors. Below, you’ll find a list of ways to cut the cost of setting up/running an indoor grow room.

Build a Grow Room Out of an Old Cupboard or Closet

Rather than forking out top dollar for a grow tent, consider transforming a spare cupboard or closet in your house into a grow room. Just remember that you’ll want to cover the walls of whatever space you use with a reflective material (white plastic or Mylar film work best). This will reflect more light onto your plants, making for a more efficient grow room.

If you’re really short on space, consider building a micro grow room using an old computer tower.

Build Your Own Grow Tent

If you haven’t got a cupboard, closet, or old computer tower to refurbish into a grow room, consider building your own grow tent using basic materials like PVC pipe and panda film.

If you’re not the DIY type, try shopping around for a budget tent online. There are many grow tents on the market for as little as €50; just don’t expect them to be packed with features or have the best build quality, but they should last you at least a couple of harvests.

Utilise the Right Lighting

There are a ton of lighting options on the market, and finding the right solution for your grow room can be quite a task. If you’re growing on a budget, however, we generally recommend investing in a quality LED lighting panel.

While LED lights come at a higher outright cost than HID lights, they are much more efficient and cheaper to run, making them more cost-effective in the long-term. Not only that, but LEDs tend to run much cooler than HIDs, which is an important factor given the spatial limitations of most indoor budget growers.

Ventilate Your Grow Room

Ventilation is something growers shouldn’t skimp on, regardless of their budget. Extractor fans help pull old, stale air out of your room/tent so it can be replaced with fresh, oxygen-rich air from outside, while oscillating fans help keep air moving throughout your grow room. Both are super important for supporting the growth of your plants and keeping your room/tent free of pests and pathogens.

To reduce the cost of your ventilation system, make sure you buy an extractor fan with a m³/h rating that will ensure the correct air circulation. m³/h (cubic metre per hour) is an indicator of how much air an extractor can pull out of a space every hour. For proper ventilation, you’ll want to invest in a fan with a m³/h 70 times higher than the volume of your room/tent. This is because the average number of air exchanges required in a grow room is around 70 per hour.

For example, if you’re growing in a tent that measures 1m × 1m × 2m (with a total volume of 2m³), invest in an extractor fan with at least 140m³/h. You’ll want the smallest possible extractor that can effectively maintain an optimal, consistent temperature in your indoor garden. The smaller the extractor, the less power it’ll use, and the more money you’ll save.

Properly ventilating a small indoor grow space isn’t rocket science, but it’s essential nonetheless. If you can avoid the occurrence of pests, plagues, and inferior results for little money and effort, why not make your life easier?

Pro tip: We also recommend outfitting your extractor fan with a carbon filter to help reduce the smell of your grow-op.

Keep Temperatures Down

If you’ve followed our recommendations up until now, you shouldn’t run into any issues with heat. Remember to use small oscillating fans to move air around your plants and keep old, warm air from getting trapped inside the room. You can also opt to run your grow lights during the night if you live in a very hot area.

Choose the Right Growing Medium

Soil is by far the most budget-friendly growing medium. If you want to further cut the costs of your grow-op, consider making your own super soil using compost, vermiculite, and organic fertilisers. As mentioned earlier, remember to reuse your old soil, if possible.

Grow With or Without Nutrients

While most growers opt to feed their plants with chemical fertilisers, there is a strong trend towards organics in the world of cannabis cultivation. In general, we always favour using organic fertilisers as they work with the soil to slowly deliver nutrients to plants.

Today, there are plenty of organic fertilisers on the market, and many of them come at a similar cost as their non-organic counterparts. However, using organic fertilisers might actually lower the cost of your grow-op in the long-run.
