What Are Indoor Cannabis Seeds?
Although all cannabis strains can be cultivated in an indoor setting, some seeds are specifically meant to be cultivated in an indoor environment. Indoor cannabis seeds are sensitive to change in the climate and prefer to be in a controlled room.
Why Should You Grow Indoor Marijuana Seeds?
If you are starting, you may ask yourself, what are the benefits of growing indoor seeds? And how indoor cultivation impacts your plants? Are they better than outdoor seeds? Are they the highest THC seeds in the market? Your response to these questions depends on the indoor strain you choose to cultivate. Indoor seeds have a few advantages over outdoor seeds. Below, we explore the benefits and cons of using indoor seeds.
Pros of Indoor Seeds
Control Over the Environment
The good thing about growing indoor seeds is the ability to control their growth conditions, such as temperature, humidity, water, nutrients, lighting, and airflow. It allows you that your plants grow under optimal conditions, which translates to better and higher yields.
Cons of Indoor Seeds
Tiring, Time-Consuming, and Expensive
Setting the grow room is a lot of work and requires a substantial investment because you need to purchase the grow kit, form the tents, lights, pots, air conditioning system, and grow medium. You may also need to hire professionals because doing a DIY setup may lead to some setbacks, affecting yields and quality of your indoor marijuana.
Tools and Equipment Used in Growing Indoor Cannabis Seeds
Suppose you want to grow indoor marijuana from the indoor seeds, you will need:
- Grow room/grow tent
- Growing lights
- Air conditioning
- Thermometer and hygrometer
- pH test kits for test soil pH
- LUX Meter for measuring and optimizing light in the grow room
- Timer for automating light cycle
- String/gardening wire for training your plants
- Containers such as fabric pots for growing your plants
- Seedling starter kit
Best Places for Growing Indoor Seeds
Now that you have all the equipment needed to grow your weed seed indoors, you need to choose the best place to grow your indoor cannabis seeds. These places include:
- The basement
- Grow box
- Closet, or
- Build a grow room
Choosing a Growing Medium for Indoor Seeds
When growing indoor marijuana seeds, you can use either soil or hydroponics as the growing medium. Soil is the most straightforward growing medium used by most cannabis growers, especially beginners. You can either buy the soil mix or create your own.
Hydroponic uses water or another soilless substrate, such as coco coir or pear as the growing medium. In this method, plants are fed with nutrients directly into the roots, giving the total grower control over the nutrient intake. This method is ideal for experienced growers and leads to improved yields.
Choosing Indoor Seeds
There are many weed seeds for indoor growing for sale, therefore, growers need to select quality indoor weed seeds. Discussed below are the 10 best marijuana seeds for indoor growing:
Sour Diesel is a well-known strain from the Diesel family that is highly potent. It is a cross between Chemdawg and Super Skunk. This strain is not recommended for beginner growers and prefers dry and warm climates. However, know how to control powdery mildew since Sour Diesel is susceptible. Therefore, it is recommended that you cultivate this cannabis strain indoors.
Sour Diesel indoor marijuana seeds grow into tall plants that can be monstrous if not trained. The strain’s flowering time lasts from 9 to 10 weeks, with 1.5 – 1.6 oz/ft² (450 – 500 g/m²) yield when it is grown indoor.
Hellfire OG is a perfectly balanced hybrid strain that gives a couch locking high. This strain was created by mixing Rascal’s OG Kush and SFV OG Kush. Hellfire OG boasts a THC content of 28 to 30% and has potent euphoric effects. Hellfire OG indoor weed seeds grow up to 7 feet (2 meters) high with compact and dense buds. Hellfire OG flowering time lasts 55 – 65 days with high yields of 1.3 – 1.6 oz/ft² (400 – 500 g/m²).
Granddaddy Purple is a beautiful purple colored strain that is a cross between Big Bud and Purple Uncle. These are top-shelf seeds that are highly sought after by both novice and veteran growers. Granddaddy Purple seeds give perfect weed plants for growing indoors because their height reaches up to 3.5 feet (100 cm) with a flowering time of 9 – 10 weeks. The strain’s buds are thick and dense with a layer of rich THC (15 – 19 %) trichomes. You can expect to reap high indoor yields of 1.3 – 1.6 oz/ft² (400 – 500 g/m²).
Chocolate Thai is a 100% Sativa strain from Dutch Flowers. Like its name, the strain was first discovered in Thailand. This cannabis strain delivers an energizing, mind-clearing high. Though it has a low THC content of 10 to 15 %, users love this strain because of its creamy chocolate taste and delicious high that does not leave you couch-locked.
Chocolate Thai is a pretty tricky indoor weed seed to cultivate, and they are best left for expert growers who have the patience of waiting out their long flowering period and low yield. Suppose you are in a cold climate, it’s best to cultivate this weed seed indoors because it thrives in a warm and dry environment.
Wedding Cake indoor cannabis seeds are Indica dominant. The seeds grow into a short and sturdy plant that thrives in various environmental conditions. These are high THC seeds with a THC content of 17 – 23 % and delivers a long-lasting and cheerful high. Wedding Cake strain flowering period lasts for around 65 days and produces decent yields of about 1.5 – 1.6 oz/ft² (450 – 500 g/m²). This strain is moderate to cultivate but is naturally resistant to various diseases and pests.
Blue Dream is a Sativa dominant strain that is highly sought after in America. This strain packs quite a punch as its THC content ranges between 16 and 20%, with 2% CBD. Growing Blue Dream indoor marijuana seeds requires patience because it grows slowly as it needs time to branch out in its early stages. The plants are tall and can hit 6 feet (180 cm) with high and healthy yields. Blue Dream is a favorite of mites, pests, mold and mildew; therefore, growing it indoor helps control humidity, facilitating the infestation.
Purple Kush Autoflower
Purple Kush Autoflower is a popular cannabis strain among cannabis lovers who love smoking this strain because of its potent high. It is got by crossing Hindu Kush and Purple Afghani.
It is straightforward to grow Purple Kush Autoflower weed seed indoors because it grows into hardy, medium-sized plants. This beautiful strain improves your garden aesthetics with its purple hues and unique aroma. Purple Kush flowering period lasts 56 – 63 days with a pretty decent yield of 1 oz/ft² (300 g/m²) when it is grown indoor.
Strawberry Cough is a hybrid strain whose origin is marred by a lot of myths. Just like its name, expect your field to smell like strawberries. This Sativa dominant strain is pretty easy to cultivate and thrives in an indoor environment.
When you plant Strawberry Cough weed seeds indoors, the plants grow up to 3 feet (90 cm) and mature in 63 – 70 days. Strawberry Cough has sturdy branches to support the weight of the tight bud with a pine cone shape.
Legend OG is an Indica dominant strain with a woody and floral aroma. Although this strain does not have a well-documented origin, Legend OG was created by Swamp Boys Seeds. This is a high THC strain with THC ranging between 20 to 25%. It grows tall and is ideal for average growers and produces moderate yields.
If you want to cultivate potent indoor marijuana seeds, Cement Shoes is our best bet. Apart from a high THC content of 20 – 24 % and 1% CBD, this strain offers you a relaxed cerebral buzz and a heavy-bodied buzz that leaves you couch-locked.

When you cultivate Cement Shoes weed seeds indoors, you get a 5 feet (150 cm) tall plant with a flowering period that lasts between 60 – 70 days. This Indica dominant strain produces high indoor yields of 1.3 to 1.6 oz/ft² (400 to 500 g/m²).

Pros and cons of growing marijuana seeds indoors
Indoor marijuana seeds for sale are an attractive option for growers of all levels, but they’re not a one-size-fits all solution. There are advantages and disadvantages to consider before making an informed purchase decision.
Keeping your marijuana indoors provides security, shelter, and stealth. On the other hand, your plants remain small, and you don’t get to experience the extreme yields of outdoor giants.
In a nutshell, here are the benefits of growing the best indoor marijuana seeds :
- Better control of all conditions
- Easy protection from potential issues
- Greater privacy and discretion
- Perpetual harvest potential
Some people still choose outdoor setups, though. Here are the comparative disadvantages of indoor cultivation :
- More expensive to set up
- No access to real sunlight
- Less microbial life
In a nutshell, indoor seeds take the gold if you can afford the investment . Let’s explore the perks in a bit more depth.
Save time with quick & easy harvests
Photoperiod cannabis crops in the great outdoors rely on changing the seasons to switch between its three life stages. As a result, the seed-to-harvest period usually takes over six months, from early spring to early fall.
Feminized indoor marijuana seeds develop into ripe crops in much less time. Flowering time is strain-dependent and should be respected, but you can half the vegetative stage .
This phase is when your crop produces branches and foliage, not buds and resin. Indoor growers can switch the lights for flowering after several weeks of vegging. That way, you get small plants without too many unnecessary branches.
A six-month life cycle is suddenly four months long , and there’s less trimming struggle along the way.
Combine this perk with our cannabis seeds for beginners , and your cultivation journey becomes a walk in the park.
Control your environment
Environmental optimization is the number one reason why many growers choose indoor seeds . Why use clones to ensure the best possible phenotype? Let each seed develop to perfection with a helping hand instead.
The outdoors brings unexpected waves of low light conditions and increased humidity, pests, disease, and other cultivation pitfalls.
It’s a different story inside. You’re in charge of the environment, letting you fine-tune the conditions. Get the right lamps, filtration systems, and nutrients for marijuana .
Use these modern tools to boost the bulk and quality of every future harvest .
Mimic the outdoor conditions, minus the bad stuff. Your rare tropical strain can easily thrive in a cold state—just up the heating and moisture. Those adaptable indica crops appreciate the lack of climate fluctuations, even if they technically could withstand them.
Never worry about infestations
Your outdoor garden is full of little bugs that find cannabis leaves a treat they can’t refuse. You could stay vigilant, plant companions in the surrounding soil, and install protections. Alternatively, keep your marijuana indoors and nip this problem in the bud .
A sealed and sterile grow room runs little risk of infestation. Even if something does slip through the cracks, the adverse effects are less severe.
Grow whenever and wherever you want
This selling point of best indoor marijuana seeds started with commercial growers but quickly spread to everybody else. Why smoke six-month-old buds when you can always have the freshest flower in your stash?
Growing cannabis inside doesn’t leave you dependent on the growing season . Sow in December and collect in March. Repeat two more times in a calendar year.
As a bonus, you don’t have to worry about nosy neighbors noticing your crop and giving you weird looks. Indoor setups let you forget all about a lack of garden space or proper shielding to keep it private.
Where to grow indoor weed seeds?
The stellar genomes of our indoor seeds make them suitable for various systems. As long as your space is clean, secure, and adaptable , you can choose whichever setup best fits your situation.
As a rule of thumb, seal the cultivation unit to prevent pests from harassing your crops. Install a ventilation system to provide fresh air to your budding plants. Get lamps to mimic outdoor sunlight—even indoor strains need light.
What growing arrangements are available? Our community goes for the following:
- Closets are convenient but far from optimal. Opening and closing the doors can disrupt the light cycle, and the air gets stuffy. Stick to one plant if closet-growing.
- Space buckets fit a single plant but provide a stable growing environment. Pick a short indoor strain for the purpose. The same rules apply as with closets, but the results tend to be much better.
- Grow tents can hold anywhere between two and ten indoor plants. These neat devices promise excellent light distribution and protection.
- Grow boxes are an alternative to a tent you make at home. Choose a sturdy wood or metal base and reflective material with a zipper for the insides.
- Windowsills are excellent for tiny crops, but they reduce harvest potential. Supplement lights with LEDs and introduce temperature control to improve this setup.
- Grow rooms are the top choice for dedicated cultivators. Having an entire chamber for your indoor marijuana seed -grown crops eliminates the downsides you’d face with other options.

A further quality of the indoor growth is the freedom in determining the best time to start the harvest, which can even take place in the winter time. An indoor set-up with a well-balanced and constant humidity / temperature / lighting rating is certain to be highly beneficial for the production of healthy plants including the ideal THC levels. Quality choices in the series of indoor seeds include Amnesia, White Widow, and Bid Bug.
Even though the seeds are more intended for indoor growth they are still able to produce in the outdoor environment providing the ideal conditions are present. Certain seeds are more resilient to mould or similar issues and therefore benefit more positively from the more structured inside set-up. If planning on producing an outdoor crop make certain to inspect the plants at regular intervals for mould or disease which can easily destroy the plants.
