The Ultimate Guide To Indoor Cannabis Growing Equipment

Explore this comprehensive guide to find the best growing equipment for your needs and skills as a cannabis cultivator.

Best Growing Equipment For Beginner, Intermediate, And Experienced Cultivators

Growing weed indoors needn’t be difficult. All you need is the right equipment. Below, we’ve built the most comprehensive cannabis grow equipment list out there—complete with everything from seeds and pots to lights and tents. We’ve even included various options for each piece of equipment suited for beginner, intermediate, and advanced growers.

Seeds

The first step to growing great weed is to start with the right genetics. Cannabis plants can vary a lot, and you’ll need to take the time to research strains and find something to suit your grow room, budget, and skills as a grower. For a complete step-by-step guide on how to grow indoors, you can check out this article.

At RQS, we pride ourselves on creating strains to suit any and every grower. Below are three strains for beginner, intermediate, and advanced growers:

• White Widow Automatic: White Widow is a world-renowned, classic Dutch strain. For this autoflowering variety, we crossed a potent, profit-yielding White Widow phenotype with a sturdy strain of _Cannabis ruderalis_. The result is a potent autoflower that goes from seed to harvest in just 8–9 weeks and produces great results regardless of your skill as a grower.

• Royal Cookies: If you want to grow top-shelf US genetics at home, this is the perfect option. Royal Cookies was bred by crossing two unique Forum 1 phenotypes to create a super potent Cookies strain with up to 23% THC, capable of producing massive yields to suit. With a flowering time of just 8–9 weeks, this is a great intermediate strain that will produce some top-shelf bud every time.

• Shining Silver Haze: If you’re an experienced grower looking for a killer sativa hybrid to add to your garden, look no further. Shining Silver Haze is our own version of the iconic Haze varieties that revolutionised cannabis around the world. With 21% THC, a 9–11 week flowering cycle, and an uplifting high like no other, this is easily one of our most beloved strains.

Grow Tent

When growing cannabis indoors, you’ll want to ensure you have as much control over your growing environment as possible. And the best way to do this is to grow your plants in a tent where you can tightly control variables like temperature, relative humidity, air circulation, ventilation, and more.

That’s where grow tents come in. Available in all shapes and sizes, grow tents make it easy to create a dedicated space for your plants without having to renovate an entire room. Below are three different grow tent options for growers of all skill levels:

• Vivosun Growbox Pro 120 × 120 × 200 cm: This spacious tent comfortably supports medium-scale grows of around 4–8 plants, depending on training and cultivar. Constructed from durable 2000D Oxford canvas and lined with highly reflective Mylar, it is fully light-proof and built for efficiency. Sturdy 22 mm steel poles and a high-CFM support kit provide excellent stability for heavier lighting and ventilation setups.
• Mars Hydro 120 × 120 × 200 cm Grow Tent Kit: Designed for growers looking for a complete, ready-to-run setup, this all-in-one kit includes a light-proof tent, Samsung FC4800 LED light, ventilation system, and essential accessories. With reliable materials, even light distribution, and generous working space, it’s well-suited for growers ready to scale up without sourcing individual components.
• RQS Grow Tent 4×4×7 ft: Built for growers who want a complete, ready-to-run setup, this all-in-one kit comes with a 450W LED grow light, an 8-inch inline fan rated at 353 CFM, a carbon filter, and matching ducting. The 4×4 ft footprint fits 12 to 16 pots, and the LED delivers 859 PPFD at 18 inches across the full canopy. It's a solid choice for growers ready to scale up without the setup headache.

Soil 

There’s a simple truth about how to grow weed: Your plants can only grow as big and healthy as their growing medium lets them. That’s why it’s super important to invest in top-shelf soil right from the get-go.

Remember, cannabis has different growing requirements than other plants. It likes slightly acidic soil with a pH of roughly 6–6.8 (5.5–6.5 for soilless grows). In terms of nutrients, cannabis needs varying concentrations of nitrogen, phosphorus, and potassium during its life cycle, as well as a rich balance of micronutrients like calcium, manganese, iron, copper, sulphur, and more.

Below are three different soil options for beginner, intermediate, and advanced growers:

• Miracle-Gro Potting Mix: Miracle-Gro is a well-established brand, and its Potting Mix is very popular among cannabis growers. It’s very well-suited for beginner growers as it contains all the nutrients your plants need in order to grow big and healthy. In fact, Miracle-Gro contains enough nutrients to feed plants for up to six months and promises to double your harvest without any extra work on your end.

• Nature’s Living Soil: This is one of the best store-bought super soils available. Nature’s Living Soil is a concentrated super soil used to enrich regular soils like Roots Organic or Fox Farm. It contains all the organic nutrients your plants need to grow big and healthy and to produce the best possible harvests. If you’re an intermediate grower looking to get a bit more hands-on in the garden, this is a great option.

• Homemade super soil: If you’re an experienced grower, nothing beats preparing your own organic super soil at home. Using natural fertilisers, compost, and other organic ingredients, you can create a tailor-made potting mix. Plus, you’ll get the added peace of mind of knowing exactly what you’re feeding your plants.

Pots

Cannabis pots come in all shapes and sizes. The exact pots you plan to use will vary more on the size constraints of your grow space than your skills as a grower. Ideally, you’ll want to give your plants sufficient room to develop a healthy root system while keeping them at a manageable size.

Most growers will usually opt for one of the following potting options:

• Homemade pots: If you’re growing on a budget, you can make your own pots out of buckets, bins, or other similar containers. If you’re growing indoors, we generally recommend using containers of about 10l. Outdoors, you’ll want to use larger containers (20l or more), especially if you’re only growing a few plants. Whatever container you use, always remember to drill drainage holes in the bottom.

• Standard flower pots: Standard plastic flower pots are cheap, easy to get your hands on, and serve their purpose. For growers with a limited budget, simple 12l nursery pots are perfect.

• Fabric “smart” pots: If you're an advanced grower looking to help your plants develop the strongest roots possible, you can't go past our fabric pots. Choose the RQS Geotextile Grow Bag for a reliable, eco-friendly option, or opt for the Grow Bag Pro if you're after a more heavy-duty solution with reinforced handles built to last cycle after cycle.

Humidifier And Dehumidifier

Humidity control is key when growing cannabis indoors, as cannabis plants benefit from different levels of humidity during different stages of their life cycle.

Seedlings, for example, like high humidity levels of around 65–70%. During the vegetative growth phase, you can gradually lower humidity by 5% every week. In the final weeks of vegetative growth, the humidity in your grow room should sit at roughly 40%, which is where it should stay during flowering to avoid issues with mold and mildew.

The best way to control the humidity in your grow room is with humidifiers/dehumidifiers. Below are three options to consider:

• Electric Dehumidifier with 2 l Tank: If you're a beginner grower with a small grow tent and just a few plants, this little dehumidifier is perfect. Once the water tank is full, the device automatically switches off to conserve power. This is a really cost-effective option for growers working with a budget.

• Vornado EV200 5l Dehumidifier: If you’re working with a medium-sized grow tent (roughly 3.9 × 3.9 feet), the Vornado is a great choice. With its vortex action, the Vornado fully circulates humidity all throughout a room of up to 65m² (700ft²). It also comes complete with three fan settings (low/high/auto), push-button controls, an electronic humidistat, and automatic humidity control.

• TROTEC B 400 Air Humidifier: Advanced growers with a larger grow tent will need a larger humidifier. That’s where the TROTEC B 400 Air Humidifier comes in. With 34l capacity, this beast can manage humidity levels in a room of up to 360m². Plus, the unit automatically switches off once it has reached the right humidity level. If you’re running a big grow op, this is the perfect solution for you.

Fans

Air circulation is super important when growing weed. Stagnant air not only creates hot pockets, but can also create a breeding ground for mold, pests, and diseases that could prove detrimental to your plants and harvest.

Luckily, managing air circulation is easy; just invest in some fans to keep air steadily moving throughout your grow space. Below are three fans you can use for your grow room:

• Lorell LLR49256 Wall Mount Fan: Sometimes, you don’t need equipment with fancy bells and whistles. That’s where this simple wall fan from Lorell comes in. This 15.6 inches (16'') fan is super simple, offering three speed settings that you can cycle through using a pull-chain. While it’s nothing fancy, it’s exactly what you need if you're a beginner grower or are working with just a few plants in a small grow space.

• Hurricane Super 8 Oscillating Fan: This oscillating fan by Hurricane is a step up from the previous model. It oscillates in a figure 8 pattern, offering maximum air circulation around your grow space. It also has three speed settings and features a strong build for extra durability, making it an ideal mid-range option for intermediate growers.

• Oscillating Wall Mount Fan: A 28.1 inches (30”) fan is ideal for more advanced growers working with large grow rooms. These industrial-strength fans are designed to efficiently keep air circulating around large spaces, like commercial kitchens and warehouses. While the airflow from these fans will be far too strong for small grow tents, it's well suited for large, professional grow operations.

Thermometer And Hygrometer

To grow the best weed indoors, you need to have complete control over your plants’ environment. Two of the most important variables are temperature and humidity, so you’ll want to monitor both of these closely using a thermometer/hygrometer.

Below are three different thermo-hygrometers to consider for your grow room:

• Digital Thermo-Hygrometer: A compact and easy-to-use device for indoor grow spaces that monitors temperature and humidity with updated readings every 10 seconds. It covers a wide range (-20 to 70°C and 20–95% RH), shows max/min values, and helps growers maintain stable conditions throughout the grow cycle.

• ThermoPro TP65A: This is the TP50’s big brother. It comes complete with a large backlit touchscreen, remote control range of up to 60m (200ft), and an extra weatherproof design that’s capable of resisting extreme temperatures as low as -35°C. The TP65A also comes with a 3-year warranty if you register your device with ThermoPro. This is a really comprehensive device built to last.

• Ambient Weather WS-3000-X3: If you’re looking for the most comprehensive thermometer-hygrometer combo, this is it. Complete with three wireless sensors, the Ambient Weather WS-3000-X3 is great for growers who have separate grow rooms for seedlings, vegetating, and flowering plants. The device also has a comprehensive data logger that graphs and logs data from all three sensors for temperature, humidity, dew point, and heat index. If you want maximum control over the environment in multiple grow spaces, you can’t go past this device.

Nutrients 

If you want to harvest big, you need to feed your plants right. And when it comes to cannabis nutrients, you’ve got a lot of options.

Cannabis needs three macronutrients to grow: nitrogen (N), phosphorus (P), and potassium (K). Different nutrient formulas will carry these compounds in different concentrations. But beyond standard NPK formulas, you’ll also want to feed your plants micronutrients like calcium, sulphur, zinc, boron, manganese, copper, and iron. Give your plants a healthy combination of all of these nutrients, and you’ll be well on your way to producing some killer harvests.

Below are three different nutrient solutions to try on your next cannabis grow (if you’re not using them already):

• Fox Farm Nutrient Trio: Fox Farm is a well-respected brand among cannabis growers. And this 3-pack of nutrients gives you all the basics you need in order to grow big, dense buds at home. Complete with a growth booster and two bloom boosters, this complete kit is perfect for beginner growers who want to keep things simple.

• Technaflora Recipe for Success Starter Kit: If you’re looking for a more advanced approach to feeding your plants, this kit by Technaflora has everything you need. It includes regular veg and bloom fertilisers, plus some micronutrient solutions including magnesium, calcium, iron, essential carbohydrates, and amino acids to really bring your buds to the next level.

• Biobizz Starters Pack: If you want to grow organically, this kit is perfect. Biobizz is another well-respected brand, and this box contains its iconic Bio·Heaven™, Bio·Bloom™ and Bio·Grow® nutrients, as well as their Top·Max™ (to improve the size of your flowers) and the Root·Juice™ to encourage root development.

• Royal Queen Seeds Easy Nutrition: this range of organic nutrients provides cannabis plants with everything they need to survive and thrive. Easy Grow meets all of the demands of the vegetative phase, whereas the specialized flowering formula in Easy Bloom encourages fast and healthy floral growth. Easy Boost fills the growing medium with vital macro and micronutrients, and Easy Roots introduces beneficial fungi that assist plants in absorbing their food.

Grow Lights

No list of growing equipment would be complete without mentioning lights. Grow lights are the heart of your indoor grow room and easily have the biggest impact on the quality and size of your harvest.

Lights come in many shapes and sizes, at varying price points. Below, we've hand-picked three of the best grow lights currently on the market for beginners, intermediate, and advanced growers:

• RQS LED Grow Light 150 W: Compact yet powerful, the RQS LED Grow Light 150 W is purpose-built for smaller grow spaces. Drawing 150 W through 696 full-spectrum LED chips across a 40×40 cm panel, it delivers 528 μmol/m²/s PPFD at the canopy, more than enough to drive healthy vegetative growth and heavy flowering in a 60×60 cm tent. Full-spectrum output covers every stage of the cycle, from seedling through to harvest, without requiring a fixture swap. Its low wattage keeps electricity costs and heat output well below those of a comparable HPS fixture. Whether you're just starting out or running a single-plant training setup, the RQS 150 W is an excellent choice for growing cannabis indoors.
• RQS LED Grow Light 320 W: Perfect for 90×90 cm tents, the RQS LED Grow Light 320 W scales up performance for mid-size grows without scaling up your energy bill. It draws 320 W through 1,260 full-spectrum LED chips packed across a 60×60 cm panel, producing 1,029 μmol/m²/s PPFD at 45 cm, comfortably inside the productive range for dense flowering in ambient CO₂ conditions. The high diode density keeps light sources close together, flattening hotspots and reducing edge fall-off across the full 90×90 cm canopy below. Run it over nine plants in 8 L fabric pots for a perpetual cycle, or drop to four plants in 18 L containers when bigger individual yields are the goal.
• RQS LED Grow Light 450 W: Designed for serious indoor growers cultivating in 120×120 cm grow tents, the RQS LED Grow Light 450 W delivers exceptional coverage and uniformity across larger canopies. Its 2,100 full-spectrum LED chips span a 100×100 cm panel, producing up to 1,074 μmol/m²/s PPFD at 30 cm and a consistent 859 μmol/m²/s at the standard 45 cm working height. The near-full-footprint panel is engineered so corner readings stay close to center readings, keeping outside-row colas finishing at the same trichome density as those directly beneath the fixture. Whether you're running a 12–16 plant SCROG table or a rolling perpetual, the RQS 450 W delivers professional-grade results without inflating your energy bill.
