Insulate Your Grow Tent Or Room: Save Money, Reduce Noise and Smell

If you know how to insulate your cannabis grow tent or room, you can save some serious bucks while growing weed indoors. This blog helps you on your way to installing your very own DIY grow space insulation with minimum hassle.

Why Insulate Your Grow Tent?

Most indoor cannabis growers these days prefer the convenience of a grow tent to use as their foldable cannabis garden. Others convert an interior space into a full grow room. Regardless, knowing how to insulate a grow tent, or how to tackle grow room insulation, can make a big difference when it comes to harvest yields, grow efficiency, and electricity bills. 

Insulation can also help keep your hobby a private affair, as insulting helps mask heat signatures, smell, and equipment noise while making your green efforts that much greener. If you mask the smell of growing weed, you can avoid detection while reducing your chances of annoying family members, flatmates, or neighbours.

Cutting Back On Those Bills

These days, power usage and electricity bills are an important part of growing cannabis indoors. Skyrocketing energy costs can really spoil the taste of your harvest, and so, cutting back on your electricity expenses helps keep your hobby fun and worthwhile. 

Applying proper grow room insulation can go a long way towards keeping growing weed affordable. Moreover, it helps reduce your carbon footprint. Trust us when we tell you your bud will taste even better knowing you have kept your environmental impact down to the bare minimum – and that’s before those electricity bills come rolling in!

Grow Room Temperature And Humidity Control

Managing your grow room or tent temperature and humidity control is crucial for healthy cannabis plants. Stable, consistent grow climate conditions give your crops the best shot at maximum harvest results. If you add insulation, it will become easier and more cost-effective to keep both relative air humidity and temperature levels constant: your premium cannabis seeds deserve it!

Protection By Insulation

Make no mistake: indoor grow conditions can be almost as unstable as outdoor garden environments. Winter outdoor temperatures affect your room temperature as well, and insulation helps counter these fluctuations. Perhaps more importantly, heat waves can crank up indoor temperatures fast, which can be fatal for anyone growing in exposed areas such as attics or extensions.

The same applies to air humidity. No matter how good your exhaust fans and air circulation are, you will be doing your plants a favour by improving the stability of moisture levels in your indoor garden. You’ll be doing yourself a favour too, because better insulation equals less worrying over sudden drops or rises in all the climate variables you need to manage when growing weed.

Differences Between Tent And Full Grow Room Insulation

Tents and grow rooms can be insulated using the same kinds of materials. You can get these materials at any DIY store at reasonable prices, so consider your grow room insulation an investment that will pay off in terms of lower power consumption and added growing efficiency.

The main difference between a tent and a full room is usually a matter of floor and wall surface: spare bedrooms, attics, and garages tend to be much bigger than a regular grow tent. This difference is offset by the number of plants your grow room can accommodate: you’ll get bigger harvest yields in return for the extra insulation you apply.

At this point, it is worth considering that you may want to insulate the room where you place your grow tent or tents. Any heat and moisture kept in the surrounding room will contribute to a stable climate inside the tent. All in all, overall insulation quality of your designated grow area is worth considering before deciding where to put up your tent. Perhaps you could even insulate your grow tent as well as the room it is in for optimal effectiveness.

Cannabis Insulation Materials

Before you get started, take a minute to determine which insulation materials best suit your needs. We will discuss the three most commonly used types of insulation to help you decide.


Fibreglass is a handy material for insulating entire homes, so it should work well in most grow rooms, depending on shape, size, and any obstacles that are part of the construction. Fibreglass is relatively affordable and pretty easy to install by yourself. 

The big drawback of fibreglass insulation for grow rooms (or even tents) is the mess it produces when processed: these fibres can cause skin irritation and even harm your respiratory system. Always make sure to wear proper protection and clean up thoroughly when you’re done.

Reflective Foil 

Reflective insulation foil is the usual means of insulating ready-made grow tents. This lightweight material is highly affordable and extremely easy to apply in problematic spaces. Reflective foil keeps heat inside while making optimal use of the light by reflecting it back into the room at different angles. Just make sure you don’t leave any light leaks open, because a tiny crack in your insulation can seriously ruin your growth and flowering prospects.

Foam Board

Foam board is probably the cheapest grow room insulation material, making it a great choice for beginners with tight budgets. It is lightweight and easy to cut into any shape you need. In addition to great temperature control, foam board gives you additional moisture resistance, although it lacks the reflective capacity of foil to boost your lighting efficiency.

How To Insulate Your Grow Tent Or Grow Room

Insulating a grow tent is usually a pretty straightforward affair. The general idea is to improve its original insulation capacity by building a containment box around your tent for extra protection. Not only will this help stabilise your grow climate; it will also keep smells and noise inside to prevent annoying buzzing sounds and other nuisances. This can be done using any of the materials described above. A simple wooden frame is a good start here.

Another option is applying insulation inside the tent. Reflective foil is best suited for this purpose, but do make sure you keep the original walls of the tent intact. Leave enough space for any extraction fans, lighting rigs, and other equipment you want to use inside your tent.

When insulating an entire grow room, you can either choose to divide the room into insulated compartments for greater efficiency, or insulate the entire outer walls of the room in one go. Much depends on the amount of space you have available – and on the tolerance limits of any other people living in the same house, of course.

Always remember to put safety first, whichever materials you choose. Wear protective equipment such as face masks and gloves when working with fibreglass. Watch out while cutting up foam board and make sure to clean up the mess. Always try to leave power lines and other important utility features intact: you don’t want to risk electrocution, or interfering with the effective power grid you had running before you decided to insulate your grow room.
