Choose a grow system that you can understand
Deep water culture may be one of the best ways to grow feminized seeds indoors, but it requires a good working knowledge of nutrient management, nutrient measurement and plenty of experience. Growing cannabis in coco fibre is easier and produces heavy crops. Many first time cannabis growers start growing with a soil mix bought from the local grow shop. Once you have grown a few crops your confidence will improve and you will understand the basics, and feel able to tackle more complicated grow systems. Keep your first cannabis grows as simple as you can, and use the local grow shop for advice. Your local hydroponics store is a one-stop shop for materials and advice.
Choosing feminized seeds for indoor growing
It’s never been easier to buy feminized seeds online. Although you have hundreds of varieties to choose from, your first decision is whether to buy feminized autoflower seeds or feminized photoperiod seeds.
Growing feminized autoflower seeds indoors
Feminized autoflower seeds grow from seed to harvest with 20 hours of daily light, taking around 75 days. First time cannabis growers are often recommended to grow feminized autoflower seeds, they are easy to grow and the best autoflower seeds can produce huge yields of several hundred grams per plant in good conditions. The Dutch Passion feminized autoflower seed collection is one of the best available, with lots of customer grow reviews.
Growing feminized photoperiod seeds indoors
Feminized photoperiod seeds are often simply called feminized seeds. They have two growth phases controlled by the amount of light. When growing feminized seeds indoors under 18+ hours of daily light they grow in a vegetive mode, producing leaves, roots, branches but no buds. When the amount of daily light is reduced to 12 hours the plants start to produce buds, this is known as the bloom phase, sometimes called the flowering phase. Depending on the variety, the bloom phase takes around 9 weeks of 12/12 light. One of the best tips for growing feminized seeds indoors is to provide plenty of light during bloom to maximise your harvest. For a 1.2 x 1.2m tent a 600W HPS is a good solution, and some growers will use higher light levels to maximise their harvest.
Feminized seeds indoors. Avoid over-feeding and over-watering
When growing feminized seeds indoors the two main mistakes we see are plants being over fed, and (for soil grown plants) over-watering is a common error. Cannabis roots need oxygen to thrive, they don’t like waterlogged soil. Allow the soil to partially dry out between waterings, this allows some root aeration. Over feeding plants can really slow down development, the tips of the leaves go brown and crispy – a condition known as nutrient burn. Experienced growers monitor their nutrient concentrations using an EC meter to measure Electrical Conductivity, they are a recommended grow room gadget to help optimise your grows. Over-feeding your cannabis plants is particularly damaging to young plants which can remain permanently stunted, never fully recovering afterwards. When growing feminized seeds indoors, start your plants at low nutrient concentrations and gradually increase nutrient concentration, backing off at the first sign of over feeding.
Feminized seeds indoors. Maintaining the nutrient sweet spot
The experienced cannabis grower is able to steadily increase nutrient concentrations throughout the grow without under-feeding or over-feeding his plants. Keeping your plants in this nutrient sweet spot will ensure that you feminized seeds grow into healthy, heavy yielding plants. If light levels are high, the root mass is healthy and plenty of fresh air is supplied to the grow room then you should get healthy plants with heavy blooms.
The best nutrients for feminized seed indoor growing
All of the major nutrient companies offer products that will grow good quality cannabis. Many growers will eventually settle on their own preferred nutrient brand and feel that using the same brand with increased skill and experience is the best approach.
High THC results with feminized seeds grown indoors
Combine good quality cannabis genetics with an optimised environment and you will get heavy harvests of THC rich buds. The latest research is showing that crops grown under high intensity LED grow lights have routinely higher THC levels compared to identical cuttings grown under HPS. Use of UVA and UVB supplemental light, such as the SolarSystem UVB during bloom can also increase THC levels. A selection of the best LED grow lights on the market can be found on our sister companies website, Crazy LEDs. As well as offering higher cannabinoid levels, LED grow lights produce less heat than HPS lights, use less energy and last longer. LED grow lights are the preferred choice of the serious hobby grower as well as the professional legal cannabis producers.

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.

Indoor Seeds vs Outdoor Seeds, Which Is the Best?
Suppose you are new to marijuana and are wondering where to grow your indoor weed seeds. The seeds you choose to go with depends on your potential, the type of conditions it requires to thrive, and weather in your region. It is best to grow marijuana indoors because you can control your cannabis plant growth conditions. But with outdoor seeds, you have little to no control in case the weather changes.
Final Thoughts on Indoor Seeds
Indoor seeds are best when you live in a region where the weather often fluctuates, making it difficult for cannabis to thrive in an outdoor setting. If you are shopping for the indoor cannabis seed, look no further because we have a large selection of Indica and Sativa indoor seeds and this guide provides you with a list of the best marijuana seeds for growing indoors.
Cannabis seeds are sold to customers over the age of 21 and are sold strictly for souvenirs or storage purposes only. The cultivation and germination of cannabis seeds is illegal in most countries. We advise customers to check the laws in their country before ordering.
Marijuana seeds for Indoor growing
Today, and thanks to the efforts of breeders and cannabis seedbanks that have been selecting, breeding and crossing genetics from around the world, the worlwide cannabis community can choose among a huge range of marijuana strains on the market.
The main aim was and still is genetic improvement, so all growers can enjoy a high quality standard that meets their demands.
Marijuana plant grown indoors
Once we are about to start an indoor crop, the main question is: What are the most suitable strains for growing indoors?
Indeed, we have lots of possibilities, and while some genetics show their full potential in indoor grow rooms , others need different conditions or growing systems to provide best results. We must understand correctly our growing system and conditions to choose the correct strains to grow.
What marijuana strains should be grown indoors?
There are several aspects to keep in mind before purchasing our seeds:
Cannabis plants under artificial lights
Plant height and structure
Probably, the most important factor when growing in indoor cabinets or rooms is plant size, since the available space is limited and plants need favourable environmental conditions for proper development.
Indoor cannabis growing started a few decades ago when different strains were grown and bred in indoor grow rooms. Thus, Sativa-Indica hybrids were mainly developed indoors and are much more adapted to these conditions than, for instance, pure Sativas, which often grow too much and take too much time to flower when grown under HPS, HM, LED, CFL or other artificial lighting systems.
Hybrid cannabis plants combine the best traits of their parents, being vigorous and strong. These strains are more easily adapted to indoor conditions than landraces, which haven’t been grown/bred under artificial lights and therefore aren’t adapted to it.
Sour Diesel, a hybrid suitable for indoor growing
Growing indoors means using artificial lighting and ventilation systems, etc. what also means power consumption. This is why we must be sure that we’ll take profit from all this power, getting the best possible yields from our plants without forgetting quality.
Plants with a flowering period longer than 10-11 weeks represent a considerable expense in power consumption. This, combined to their height, made breeders to cross Sativa plants with Indicas to shorten both features, thus creating the socalled Indica-Sativa marijuana hybrids , plants that show an excellent and balanced combination between the main features of both parents.
Some examples of cannabis genetic lines suitable for indoor growing are varieties from the White , Blue or Skunk families, as well as Indica-Sativa and Sativa-Indica hybrids.
Growing Sativas in indoor growing tents
Colombian landrace, a difficult strain to grow indoors
As we have seen, indoor growing allows us to grow lots of different cannabis varieties by using lamps and ventilation systems.
Sativa plants can easily grow too much when grown indoors, although the experienced grower can handle this by using different pruning and training techniques. The SCROG technique , for example, enables the grower to keep the height of the branches uniform and under control.
However, and even if the grower is capable of keeping the height under control, the flowering time of Sativas is often too long (12-20 weeks), so – for most growers – they take too much space and time to be worth the effort.
If we don’t have appropiate climate conditions in our area to grow old school Sativas like Oldtimers Haze , growing our plants indoors is our only choice, so if we want to enjoy pure Sativas like that we’ll have to be patient!
How to grow autoflowering plants indoors?
A few years ago, the Lowryder strain was created, an automatic hybrid based on a Ruderalis plant that blooms automatically, regardless of the photoperiod. Since then, lots of autoflowering hybrids have been developed from the Lowryder genetics, which have quickly earned their space in the cannabis scene. Initially, these strains were mainly developed for outdoor crops, although, over time, they have shown greats results in indoor grow rooms too.
To obtain best results under artificial lights, we should use 400-600W lamps with a photoperiod of 16-20 daily hours of light. On the other hand, when we grow photoperiod strains (18/6 during growth and 12/12 during bloom) our power bills will be lower, so our grow room is much more efficient when using photoperiod strains rather than autos.
Cannabis seedlings growing indoors
The same happens with Early strains, which were bred for an early outdoor harvest. Sometimes, these strains don’t react well to a sudden change of photoperiod and start flowering when they reach sexual maturity, just as happens with automatic varieties. In this way, there is always a chance that these plants start flowering automatically, and not when the grower decides.
We hope these tips helped you to choose what strains to grow indoors depending on your needs and means. Of course, this guide should be used only as a reference, since many experienced growers won’t hesitate to flower their Sativas during 6 months to obtain quality over quantity.
