The basics of indoor cannabis seeds and growing
With marijuana traditionally being cultivated outdoors, moving the growing process inside was quite a leap forward. Growing cannabis indoors, even with beginner weed seeds, can be an exceptionally profitable venture, typically resulting in plenty of high-quality pot.
Growing cannabis from seeds indoors isn’t without its challenges. The startup cost is significantly higher, and the cultivation process is more labor-intensive than growing weed outside.
When growing cannabis from seed indoors, you're not at the mercy of the elements or weed seasons.
When growing weed seeds indoors, you have total control over the environment and your cannabis crop. Setting up inside allows you to micromanage every aspect of the life cycle, including:
- Feeding schedule
- Humidity and temperature
- Light schedule
Even though indoor marijuana won't be exposed to the elements, you should still invest in strains with the highest reward. It’s essential to always seek top-quality from a reputable brand, whether buying indica or cannabis sativa seeds.
We recommend that you get the best indoor marijuana seeds for your pocket.
What are indoor weed seeds?
Unlike outdoor seeds, indoor cannabis seeds generally do better when cultivated inside. They can be more sensitive to adverse weather and prefer being in a controlled environment.
If you compare indoor marijuana seeds to outdoor strains...
- There's nothing unique regarding the way they flower
- Their nutritional requirements are the same
- Their genetic makeup shows no great variances
What, then, makes indoor cannabis seeds special?
- Indoor strains are derived from generations of backcrossed cannabis cultivars known to thrive inside grow tents, cupboards, and rooms.
- Premium indoor weed seeds are usually feminized. Growers can't risk male cannabis plants in a confined space as they can pollinate the entire crop.
Where can you find indoor marijuana seeds for sale in the USA?
Cultivating weed is still illegal under federal law and in many states. Therefore it's crucial to familiarize yourself with your region’s laws before ordering seeds online, as every state has a different outlook on cannabis-related products.
In the past, cultivators had to get their weed seeds for indoor growing from a black-market dealer. The seed quality was often poor, and there was no guarantee you would get the strain you wanted. Prohibition has changed things, opening the door to a wider range of buying options.
Americans looking for cannabis seeds for sale can either visit their local seed shop in legal states or buy from an online seed bank.
Local seed store
In legal states, you can get your indoor marijuana seeds from your local weed dispensary or seed store.
Even though these dispensaries generally stock indica, sativa, and hybrid marijuana seeds, you'll never know if they've been damaged during transport or how long they've been sitting on the shelves. They also tend to have a limited variety of indoor plant seeds for sale, and they're typically more expensive.
Online seed bank
The better option for obtaining your indoor seeds is to buy from a reputable online seed bank, such as Homegrown Cannabis Co. These companies usually have an immense selection of premium marijuana strains available at reasonable prices, and their products are always guaranteed.

How to choose the best indoor marijuana seeds for you?
Choosing the right indoor marijuana seeds can be a confusing, slightly overwhelming experience. With literally thousands of strains available, how do you select the one that's right for you?
Seeing that you're growing pot from seed indoors, feminized seeds are most likely your best option unless you want to breed cannabis; in that case, regulars will be better. On the other hand, you may want to consider an autoflower variant if you're restricted to a specific schedule.
You'll also need to keep in mind your reason for growing indoor weed. Do you need cannabis for medical or recreational purposes? While high CBD strains are better for medicinal use, recreational users typically prefer high THC cultivars.
Ultimately, choosing the right indoor seeds will help set you up for success even before starting the germination process. Here's a list of the most important factors that should determine your final choice:
- Grow difficulty – are the seeds beginner-friendly?
- Flowering time or growth rate
Take note: When you're buying weed seeds for indoor growing, it's essential to always do so using a well-established, reputable seed bank that ensures discreet packaging and delivery, such as Homegrown Cannabis Co.
What's the difference between growing marijuana indoors and outdoors?
Growing pot from seed indoors and raising marijuana outdoors both have their merits and disadvantages. Cultivators worldwide tend to argue over which method is the best.
While cultivating marijuana outside is cheaper, growing indoor weed allows you total control over your crop.
Even though there are various factors, such as experience and finances, that may influence your decision, whether you should raise your feminized, autoflower, or regular seeds indoors or outside ultimately comes down to four things:
- Your climate – If it's too hot or too cold, or if you have unpredictable weather patterns, you may want to consider an indoor setup.
- Land availability – If you have enough space in your garden or nearby woods, an outdoor grow is the better choice.
- Privacy - Nosey neighbors can always be an issue, and there are some strains with a very pungent odor that may cause offense.
- Your personal preference.
To assist you in choosing the method best suited to you, here's a comparison of the pros and cons of each.
Indoor weed cultivation
> Growing indoor bud grants you full control over the production process and environmental conditions.

Why grow cannabis indoors?
The beauty of growing cannabis indoors from seed is that you're in full control of the cultivation environment, meaning you can constantly keep your shrubs under optimal conditions.

Is it easy to grow indoor cannabis seeds?
Deciding to grow your weed from seed indoors shouldn't be taken lightly. Even though it's not rocket science, there's quite a bit more to it than merely sticking your seeds in the soil and putting a roof over their heads.
It's an easy trade to learn, but becoming a master cultivator will create a happy stoner for life.
You need to consider your success and safety above all else and keep in mind that every growth method has its risks.
If you're cultivating marijuana outdoors, nature supplies all the right environmental factors, including CO2, nutes, ventilation, sunlight, water, and oxygen.
When growing weed seeds indoors, you're the caretaker and therefore responsible for artificially providing all the required conditions.
To successfully raise indoor weed, you need to understand cannabis fundamentals, including:
- Light and lighting schedules
- Growing medium such as soil, rock wool, vermiculite, perlite, and coco coir
- Air requirements
- Watering and pH needs
- Temperature control
- Nutrients and supplements
- Humidity control
- How to set up your control room
- The best indoor seeds to use
Once you've got a firm understanding of the fundamentals, built your grow room, and obtained the indoor THC or high CBD seeds you want to raise, you're ready to start cultivating your own indoor weed.
What are the best lights for growing marijuana indoors?
When growing pot from seed indoors, you as the cultivator need to choose the best lighting possible for your setup. With various options available, finding the most fitting solution may require you to do a cost-benefit analysis and some research.
Indoor growers generally use T5 or LED grow lamps to start their seedlings. As the flowering stage begins, they typically switch to HPS lights. Regardless of your preferred method, it's crucial to keep your lamps at a safe distance from your plants to prevent your indoor bud from undergoing unnecessary stress or light burn.
The lamps most commonly used by cultivators for growing indoor marijuana seeds are:
HID grow lights
The models most frequently used by cannabis growers are ceramic metal halide (CMH or LEC,) high-pressure sodium (HPS,) and metal halide (MH.) Options vary between 150W and 1,000W per lamp.
These lights are the most frequently used options in the indoor weed community. They're easy to use and are known to produce the highest yield for the power spent. They do emit a fair amount of heat, though, which is a vital aspect to consider when you're planning your general grow room environment control strategy.
Fluorescent grow lights
The available options are compact fluorescent lamps (CFLs), and T5 grow lights.
These bulbs are highly cost-effective, and they're commonly found in hardware stores. They produce very little heat and usually fit into any standard household light bulb socket. They also don't emit a large number of lumens to your indoor weed leaves, making them best suited for growing tents and other small-scale operations in which you can place them close to your shrubs' canopy.
LED grow lights
Various light-emitting diode (LED) grow lights are currently available on the market.
You can't go wrong by investing in LED lights specifically designed for indoor weed cultivation. It may be the newest technology on the market, but it even tops the highest yielding HPS lights in terms of results.
What is the average flowering time for indoor cannabis seeds?
The final stage of development for a photoperiod indoor weed plant is the flowering period. During this phase, your shrubs will start to produce their resinous buds. Although the average blooming time for photoperiod plants is 8–9 weeks, some strains, especially sativas, may take longer.
This process occurs naturally outdoors as summer turns into fall, and the plants start receiving less light every day. Cultivators growing pot from seed indoors can initiate the flowering period earlier by reducing the amount of brightness their shrubs receive from 16 to 12 hours per day.
There are three subphases associated with the flowering period:
- Flower initiation (weeks one to three)
- Mid-flowering (weeks four and five)
- Ripening or late flowering (week six to harvest)
A few things to consider when your plants enter the flowering stage are:
- Avoid pruning your plants during the flowering stage. It can upset their hormones
- Trellising your plants may be necessary to support the developing buds
- Feed your plants bloom nutrients (phosphorous)
The process for autoflowering indoor weed seeds is significantly different. Auto's don't flower according to a light schedule.
Instead, they start developing buds after a specific amount of time in the ground. In general, the average growth rate from seed to harvest for autoflower cannabis ranges between seven and eleven weeks.
Facts about growing weed seeds indoors
Here are some facts about growing cannabis from seed indoors that may help you avoid growing venture mistakes:
- Just start growing. There's no tool better equipped to teach you than experience.
- If you're unsure that you're cut out for growing indoor weed, start small.
- Avoid doing spur-of-the-moment experiments on your crop. At least research your idea online for five minutes first.
- Suppose you notice that something’s wrong with your crop, don't hesitate. Immediately try to identify the problem and get it sorted out as soon as possible. The longer you wait, the more potential damage it can do.
- If you run into issues, don't stop taking notes. Documenting problems is invaluable information that you can always refer back to for help during future projects.
- Be aware of the timelines, and be sure to clear your schedule for the duration of your plants' development. Indoor marijuana seeds typically take between three and five months to develop fully, and you'll also need to account for another three-plus weeks for your buds to dry and cure.
- Pay close attention to pH. Proper pH levels are crucial for your weed crop to absorb the nutrients they need.
- More nutrients don't equal more buds. Over nourishing your crop could result in nute burn.
- Strain genetics makes a tremendous difference in your indoor weed growing and yield results.
- Avoid problems related to excessive heat; vent your growth space.
- Resist the temptation to harvest early. Reaping your crop at the right time will reward you with a bigger yield of more potent, better-tasting buds.
