Essential tips to remember...

First-time indoor weed farmers have a barrier to cross. Unlike in the great outdoors, where nature provides the conditions for developing cannabis, you’re in charge of everything

You’re the one who makes it or breaks it, which is positive but puts a lot of pressure on you.

We’re here to ensure you get all the right equipment and knowledge to overcome this obstacle and come out stronger on the other side.

Learning the ropes of indoor cannabis cultivation can be complex. It’s an intricate process with many moving parts. Still, neither aspect of the challenge is insurmountable. 

All you need to do is take it one step at a time until you’ve ticked all the boxes and set yourself up for success.

Strap in. We’ll run you through the benefits of this setup, the required equipment, and some basic strain-picking tips. You’ll have a solid foundation for future research, and eventually, a marijuana garden flourishing at home. 

Why grow indoors?

Growing weed indoors is a valuable alternative to planting your seeds in nature. It lets you provide the conditions necessary for your preferred marijuana strain to thrive, no matter the immediate surroundings. 

You dedicate an enclosed space for cultivation and introduce the conditions yourself until they mimic the optimal outdoor environment.

For instance, imagine living in Vermont and dreaming of Maui Wowie, a cannabis crop used to a tropical set of environmental conditions. It’s as easy as turning up the heat and humidity. It’ll thrive even as the temperatures drop below 70 °F in late summer. 

Here are the main benefits you get from this setup.

Growing environment control

When you plant indoors, all successful growth requirements are under your complete control. For instance:

  • Day and night temperatures
  • Humidity
  • Light exposure

There’s also no risk of sudden extremes, like storms or cold spells in the middle of the summer. 

Crop safety

Apart from staying protected from unexpected weather conditions, your indoor cannabis is safe from pests, mold, prying eyes, and wandering hands

Of course, you still might face cultivation pitfalls, but the chances of that happening are much lower than with outdoor marijuana.

Crop quality and consistency

Each little cannabis seed carries massive potential, but the environment determines how much of it gets realized.

Environment optimization is much easier in a grow room. You’re in charge of maintaining optimal conditions for the highest-quality possible harvest.

For instance, there won’t be a time when one crop is receiving less light exposure than the others. All receive the same nutrition, soil, temperatures, and outside conditions, leading to consistent, quality output

Zero calendar dependency

When you cultivate outdoors, you depend on the natural seasons. By taking things inside, you can start seeds in mid-summer and harvest in February, just as you would sow in spring and collect in fall. 

You’re also free to plant year-round. A continual cycle keeps your batch of fresh flowers coming, no matter how bleak or cold the day might be.

Do these benefits sound worth your effort? Great. Let’s discuss the practical aspects of indoor growing.

What do you need to get started?

Okay, you’re ready to launch your indoor growing operation. Next up, shopping and decision-making. Here’s what you’ll need to get your grow room ready. 

Tip: You can always introduce more elements later to optimize certain aspects of your setup. These are the barebones.


Assign a certain area to your budding plants. It can be a window sill or an entire spare bedroom, as long as it’s dedicated and constant. Plants don’t react well to frequent environmental changes. 


Hanging HID

Lamps replace the natural sunlight your crops would receive outdoors. It’s among the most significant factors to get a little seedling advancing into a ripe, mature plant. 

High-intensity discharge lamps (HID)

HID is the industry standard for indoor gardens. These lights are consistent, reliable, and despite their relative clunkiness and lack of flexibility compared with more modern solutions, still the growers’ choice.

Light-emitting diodes (LED)

LED lighting systems are modern and innovative compared to HIDs. Their different light spectrums help farmers optimize photosynthesis. 

These lights also open the doors to experimentation with ranges for each growing stage. Check our grow cycle LED options for vegging and flowering. Alternatively, pick a full-spectrum product to keep it simple.

Compact fluorescent light (CFL)

CFLs are a bit less powerful than their two main competitors. People often supplement either HID or LED with CFL. If you’re only getting started and keeping things super small, they can be an excellent resource.

Climate Stabilizators

Outdoor climate influences indoor temperatures. 

Even the most enclosed room isn’t cool and dry if the outside air is constantly warm and humid. So employ thermometers, space heaters, coolers, humidifiers, or dehumidifiers to make the space suit the cannabis strain you’re growing. 

As a rule of thumb, use meters to measure the current environment in your grow room. Compare the figures to the needs of your desired cultivar, and then introduce equipment to equalize the two.

Air circulation

Like all living beings, vegetation requires fresh air to survive and thrive. Carbon dioxide is essential for photosynthesis, necessitating a steady airflow through the grow room

Exhaust fans and ventilators are your friends. They provide a light, consistent breeze and ensure plant health. 

Growing equipment

Once your grow room’s all set, the next step is to buy seeds and the accompanying equipment, including:

  • A growing medium (soil is ideal for newbies)
  • Pots and containers (ideally in several sizes for transplantation)
  • Nutrients and fertilizers 
  • Watering buckets
  • Scissors, shears, or trimmers

You don’t have to purchase everything at once. For instance, your plants won’t need branch-supporting stakes until late flowering, if even then. So start with the basics and add on with time.

Find the best spot

An entirely separate room isn’t a must for your indoor growing setup. Although it’s the easiest option, not everybody has that privilege. 

Even if you do, you might still be iffy about the entire idea. How can you be sure that cultivation is your jam if you haven’t even tried it?

Lucky for you, there’s a range of options at your disposal.


Any climate controlled indoor space. Tents come in sizes as small as 2 x 2 ft 

And as large as 20 x 12 ft

Grow Tents give you an easy to control environment.

Tiny spaces

Drawer, bucket, or box. Perfect for microgrowing.


The best option for small-scale beginners. Easy to convert into a controlled space, discreet, and efficient.


Light-sealed with a stable climate, excellent for larger-scale cultivation. Be careful about ventilation.


Usually large and well-connected with the power and water sources. Often aren’t well-insulated, though.

Grow rooms

Separate rooms in the house dedicated to cultivation and outfitted with all the necessities. Ideal for long-term planning.

Which seeds should you use?

The grow room is ready, and there’s fun stuff ahead. So you’re about to pick a strain, buy seeds, and get the action started. 

Not every cannabis cultivar is suitable for beginners. Let’s touch upon the process of finding the perfect first strain.

Top strains for beginner indoor growing

Many strains boast various resistances and self-reliant features that make them great accomplices for absolute beginners. You’ll find more than you can count in any seed library!
