Where Can I Buy Indoor Marijuana Seeds?

All of us who have ever tried to look, know that this is a common question among members of marijuana growing communities. Finding the best indoor cannabis seeds has been, for the longest time, a game of hit or miss, but we are seeing a shift in the right direction.

Back in the day, it was a lot easier to find seeds because sinsemilla only started turning up in the 70’s and, if you got a good bag of weed, you were probably blessed with a few seeds too! Things have gone the other way since then. When a seed was found in a bud a few years ago, it would have spoken to the incompetence of the grower, the low-quality of the bud, or a sullied name.

But today, we have a different problem: the flooded market. Too many companies with too many seeds have popped up everywhere in response to legalization. Of course, there exist those organizations which have been around for ages and are above reproach; however, they are few, and we still need to know where to buy some killer indoor seeds.

Weed Seeds USA, The Home Of Indoor Pot Seeds, utilizes only the most dedicated breeders, employs the friendliest and most knowledgeable staff and a seed vault bursting at the seams with the most highly-tuned genetics.

Top 5 Popular Indoor Strains For Beginners

You don’t have to be an expert to grow indoors. If you are doing research, piecing some good gear together and have a basic understanding of the principles of gardening, chances are you will be all good. Here are a few strains we like, to keep your grow streamlined and easy breezy.

Northern Lights #5: This pure indica strain is short, manageable, fairly fast and disease-resistant, benefits from a controlled environment and is gorgeous. Mid-high THC counts aren’t over the top and she delivers consistent yields.

Auto Blueberry: This tasty little treat has been around a long time and now it is available in autoflower. This is a good one to start with because, not only does this indica have a cool lineage, it doesn’t need a shift in light to flower. This allows the beginner to focus on feeding and watering.

Grandaddy Purple x Bruce Banner: This northern friend likes it a bit cooler, so dial those climates in and watch this monster explode. She likes a lot of food and a lot of light and, if you show this incredible strain all the love it deserves, it will love you right back come harvest time.

Auto Purple Kush: An all-time favorite the world over, the beginner too can experience the freedom of enjoying this bush without the anxiety of timers. Ready in just 8-10 weeks, this big purple high-THC beauty is capable of delivering up to 3.5 ounces of bag appeal.

Green Crack: For an energizing buzz set to carry you through clouds of euphoria, try this one. A stellar cross between Afghani sativa and infamous Skunk #1, there is no going wrong here – and she’s done in just 8-10 weeks!

How To Properly Germinate Your Indoor Seeds

Those hoping to learn how to grow marijuana indoors should be aware that, though every stage of development is crucial and has its own set of rules, nothing will happen at all without proper germination.

There are a few ways through which one happy cultivator may reach the root.

1. Direct Sowing: Marijuana seeds do not like to be buried, so just make a divot with the end of your finger, no farther than the first knuckle, drop the seed into the little crater, sprinkle some soil overtop and add a few drops of water.
2. Paper Towel Method: Place a wet paper towel on a plate, drop your seeds on to it and fold the paper over them. Make sure that there is no excess water, then place it in a dark location. If you have kept it in the dark, kept it moist but not wet with plenty of ventilation. Over a couple of days, the taproot should become ready for soil.
3. Overnight Soak: Place your seeds in a small glass of water. In the morning, viable seeds should have sunk and become ready for soil. The others can be left a little longer, but if they have not fallen by the next afternoon, they may be duds.

There are a number of other ways to sprout a seed, like rockwool and peat pucks, but these are the three most popular methods used among our staff and extended flower family.

Different Ways To Grow Your Indoor Seeds

Once you have popped your seeds and they are showing their first leaves, you are growing weed indoors. Like we said, growing weed indoors for beginners never has to be as daunting an experience as it seems and there is always a next logical step.

Some people let them get to the first transplant in a solo cup. These are very popular and tend to work, but you must be sure to place air holes on the sides as well as the bottom.

Another possibility is that the seeds are autoflowers, in which case, you direct-sow into the pot they will spend their lives in.

If you are growing in rockwool, simply place a bubble over the tray and allow the roots to spread outward before placing into its vegging pot or DWC. The same goes for peat pucks.

However you decide to grow your seeds, they need to be kept at 70-75 degrees Fahrenheit and an aim of 75-85% humidity if they are to remain viable until the vegging stage.

No matter what types of mediums you like to sprout your beans in, we have indoor weed seeds galore to get you there!

Growing Basics For Indoor Cultivators

Understanding the basics does not mean looking into how to grow cannabis cheap. When growing cannabis indoors in a proper indoor grow setup, indoor grow lights, meters and other equipment don’t have to be super expensive, but going the extra mile is worth it. Curiosity is also required when growing plants indoors. We must enjoy investigation, learning about new products and services, new methods of cultivation, and we must be able to write off a disaster as just a failed experiment.

Aside from the philosophical debate, there are a few points which touch all grow rooms, no matter what. These places need a clean environment with reflective surfaces (white it best), a broad-spectrum light source, a source of clean water with low ppm, heat (generally the light is warm enough), humidity (after the vegging stage, plant transpiration generally takes care of that), vegging and flowering nutrients, soil medium, coir, hydro or DWC, and you have to have the right genetics.

If the above-listed items and systems are in place and you are able to control them, you are in a good place to grow some dank buds. But be patient with yourself and honor the learning curve. We don’t start out knowing all there is to know and it takes time, research, trial and error to get it dialed-in. Remember, it’s not a race.

Training Your Indoor Marijuana For High Yields

When growing marijuana indoors, there are a lot of things one needs to pay attention to in the vegging stage, and training is most definitely right at the top of the list. There are a number of different ways you can train your indoor crops and to do so will improve your yields every time.

ScrOG: The screen of green can be utilized with any indoor grow and, for the home or tent grower, where space is limited, it pays to practice this training. For photoperiod strains, top the plant at the fourth node and place a screen over the cut site. As the branches elongate, weave them through the screen. As the screen fills, the grower creates a horizontal growth plane. This makes lighting a cinch and allows for each and every node to grow evenly. For autoflowering strains, don’t top, just weave.

If you do not wish to get into scrogging, then simple bend and tie techniques are popular and accomplish much the same aim, except it is not quite as controllable.

SOG: If you have multiple stages like seedling, vegging, flower rooms, then you may be aiming at a Sea of Green. Take clippings from underneath the canopy, veg plants for only two weeks before flipping to flower and pack those plants close together. This way, you can fit a plant every square foot and they will be finished quickly.

Check our our guide on growing kind seed in soil.

It doesn’t matter how you decide to train your crop, as long as you stick with the plan and get as much light to each and every node as possible.

Benefits Of Growing Marijuana Indoors

When you employ an indoor grow room, you have control over the environment and you do not have to worry about whatever is happening outside with the weather. Therefore, you have the capacity to hammer out the best indoor strain for yield and potency in 2021, whatever that is at the time. This means you can grow successfully, anywhere in the world!

Growing inside can be the only option citizens of some states have who are not allowed to be growing outside or those who do not have the energy to get out into the garden. A simple grow tent setup in the corner of the room or in the basement can make all the difference between no buds and great buds, grown right at home.

Chances are that with growing inside, because you have complete control over what happens, there is little chance of pests like mites and other beasties making their way into the grow space and disease. As long as you keep rH low, pests will not find a hold to grab on to.

Also of benefit is the fact that, unless you have a pushy iguana or a curious cat, there are no pesky herbivores inside your house who are going to eat your hard work! No deer or raccoons to dig in your soil for grubs and no birds top-dressing your precious buds with their waste.

Overall, there is nothing like a well-grown indoor crop for cleanliness, balance of vigor, beauty and, though yields can be a bit smaller, depending on the size of the room, the harvest is still fruitful and it’s all there because of you.

Challenges When Growing Marijuana Indoors

So, you want to grow the best indoor cannabis strains, but have faced some obstacles. There will always be challenges when growing weed, but growing from kind seed inside a controlled environment comes with its own set of possible issues.

Buy Indoor Seeds Online and Grow with Led’s

Try growing cannabis indoors without artificial light and see how far you get. Some people think that keeping their weed in a bright window is going to be enough and they wonder why their plants are long, lanky and not producing. Marijuana needs high and intense light levels if the grower is going to see success. Along with those high levels of light, the grower must supply heat, humidity, ventilation and maintain a clean environment. If any of these conditions are not met or are over-met, there can be problems.

Another major issue when growing inside is water pH and ppm (parts per million). In cities, where water systems are pounded with harsh chemicals like chlorine, water counts can be unhealthy even for humans, let alone picky cannabis plants. A ppm of 350 or higher is not uncommon in these situations, along with a pH of either up around 8 or as low as 4. Though pH is easily corrected, ppm has to be decreased through filtration or the use of rainwater, which is an average of 1-2 ppm. Reverse osmosis water systems are recommended for any city, spring or well water, as is letting it sit, bubbling overnight in order to decrease dissolved chlorine (which will evaporate).

Indoor Seeds and Alkalinity for Home Growers

PH is the acidity/alkalinity level of your water/soil and, no matter what it is coming out of the tap, a few hours bubbling with a gas stone and a few grains of organic pH up or down will fix it. BlueSky Organics makes a great pH product, safe to use in pools, aquariums, and on your plants because it will not continue to build salts in the soil. When using these products, be sure not to use both up and down, as this is detrimental to chemical processes and is too much buffering. If you go over or under, use fresh water and try again.

Rainwater is the very best source you can possibly use and, if you are running supersoil, chances are you don’t even have to worry about pH. Ganja likes a range of between 6.1-6.8 (6.5) in soil and, if you are running hydro, your weed is going to want a pH of between 5.5-6.3 (5.8). Cannabis is not forgiving about pH problems, so buy the good soil and liquid meters and always remain on top of it.

Creating The Best Indoor Climate For Weed Plants

Growing the best indoor strains means you have to have that climate dialed-in! Challenges in getting the light at the right intensity and height and getting the VPD or vapour pressure deficit correct, is a combination to monitor, constantly.

Best Grow Lights For Growing Cannabis From Indoor Seeds

As far as best grow lights go, it completely depends on what you’re running, as long as you aren’t relying on a cheap indoor grow setup. Inexpensive doesn’t have to be cheap, and it doesn’t have to break the bank, but just don’t build it with pennies. LED? CMH? HID? Place your hand directly over the canopy and drop your light. If you can feel the warmth on the back of your hand, raise the light until you cannot. This is standard for flowering and vegging requires no more than half of the flowering intensity, but can be turned up over time with dimmable systems.

Vapour pressure deficit is another aspect of indoor growing which must be dialed-in. There are some industry standard temp/rH calculations which work, but to follow a professional VPD Cannabis Chart is always the best place to start. Generally, seedlings/clones need 70-75F/75-85% humidity; vegging plants require 68-88F/60-70% humidity; flowering plants require 68-85F/40-50% humidity; and, late-flower requires 65-80F/30-40% humidity. Each climate will be a bit different, but these numbers are always a fair place to start and success has been achieved by remaining within these spectrums.

So, you’ve got your light going, your humidifier is keeping it pretty constant in there and your plants seem to be having a good time. What else could go wrong? We need to talk about ventilation. A good grow space, depending on its size, will have multiple oscillating fans, a couple stationery fans and in/out filtered air. In order to filter the air coming into the room, you can use a tower or two by the intake or you can use a carbon filter like the one used on the out vent. Carbon filters are important to marijuana growers because they trap dust, pathogens and on the out end, they cut smells. Always have a carbon-out, especially for the flowering period.

Managing Your Indoor Marijuana Pest Problem

To be successful at indoor growing requires a sure hand. Issues such as powdery mildew can come when the humidity within the flower is met by high ambient humidity. If there is not proper ventilation in place, mold and mildew can form. Though this is easy to clean if caught early, with a 1:9 milk:water solution, it can spread quickly and wreck any crop. Ensure your ventilation system is changing the air in the room at least a couple times per minute and the risk of things like powdery mildew decreases.

Fungus gnats are another issue inherent to indoor soil growing and, unless these are treated in a preventative manner, they can take over any room or tent, releasing a cloud of flies every time you open the door. Keep the top couple inches of soil on the dryer side from the start and chances of infestation decrease. Sprinkling some diatomaceous earth on the soil surface or applying a thick layer of perlite will keep the soil surface dry enough for their larvae not to take hold.

Spider-mites are a common pest to indoor gardeners. They are such voracious predators that, if not caught early and treated effectively, the weed you have spent months babying will be worth nothing. These little critters tend to move in just about the time you drop the humidity for final flowering. Just when everything is looking good, no worries about gnats or mildew and gorgeous buds just a couple weeks away, BOOM! Spider-mite infestation. It is greatly recommended that, just before late-flower, you spray your crop with an organic solution such as ‘Safer’s End All’ or dust the whole crop with diatomaceous earth. These are preventative measures which, if successful, will save your harvest from these awful little monsters.

Some things we can do to ensure against pests are: change your clothes before going in the room, ensure proper ventilation, keep animals out of the room, keep beneficial insects like ladybugs, and always clean and sanitize the environment between each grow.

Planning Your Indoor Growing Schedule

Aside from when to feed and when to water, which is a lot of work, planning in all aspects is necessary to a successful grow. There are a number of different schedules all going at the same time and all are just as important as the next.

In fact, many of these schedules rely on one another as an interplay of nutrient uptake, lighting schedules and phases of growth are always on the go. This can be confusing so it is important to employ an indoor grow calendar or some other means of keeping track.

There are a few things you need to have in place if you are going to see clear skies when growing weed. Having all of your different water testing and pH equipment handy and kept together is a good plan. Pre-mixing dry amendments to make your scheduled teas is a good plan and make sure that, if it takes a day to make your water, you give yourself that day.

Knowing from researching your genetics how long the flowering cycle should take is imperative to planning anything because one must be able to check off each week of flower, so the feed and the water, as well as, the temperature and humidity settings are correct.

Overall, there is lots to do, so the more you can write down and keep track of, the better. Lists, calendars, different coloured inks, etc., are all ways you can keep scheduling simple, therefore, winning at weed.

Providing Indoor Marijuana Plants The Right Nutrients

The nutrient requirements for indoor cannabis are no different than that of outdoor. Where these differ is that one of them is outside, growing naturally, with all the nutrients and minerals it needs, no sweat. The other one is in a 2-5 gallon container and it is your job to make it think it’s in the wild.

There are three main elements cannabis needs on an ongoing basis which we call macro-nutrients. These are: Nitrogen (N), Phosphorus (P) and, Potassium (K). for vegging phases, a balanced 4-4-4, for example, is preferred. Come flowering time, something like a 2-8-4, something with higher levels of p and k, is more appropriate. This is because, when a plant is growing, it needs nitrogen and when it shifts into the later stages, it requires more p and k in order to help it bloom.

There are secondary or micro-nutrients which are also paramount to plant health. These include Calcium, Magnesium and Sulphur and are generally found in a product called CalMag+. Marijuana plants suck up these micronutrients on the regular, so throw a few drops in with each watering.

There are also many Trace Elements which must be present for the roots and microlife to feed off of. These include zinc, iron, boron, manganese, chlorine, etc, and must always be there. These are generally added at the soil construction phase by adding things like greensand, rock phosphate, oyster shells, insect frass, and alfalfa meal.

These nutrients along with the climate should make for a healthy crop. It pays to further research these things because, depending on what style growing you are into, the ratios and timings will change.

Growing Indoor Marijuana Organically

The highest yielding indoor strains 2021 are all better from soil. The most expensive marijuana in the world is coming from soil. The tastiest and most terpene-rich smoke anywhere in America comes from good, healthy soil and we won’t compare it to synthetic chemical fertilizers, which only serve to kill our beneficial microlife we love so dearly.

Nothing compares to building your own soil, feeding flourishing microlife and watching your weed explode because of it. Starting with a full bag of good potting soil, mix in 20% perlite, 20% pumice, 20% vermiculite, 40% worm castings, 20-30% pre-rinsed coir, and you have yourself a great base. It is crucial that you use rinsed coir because of the high amounts of salts present otherwise.

Now, you want to add your dry amendments. Things such as alfalfa meal, bone meal, blood meal, kelp meal, insect frass, soluble seaweed meal, azomite, dolomite and others are what will take your soil to the next level. Books like ‘True Living Organic’ by The Rev are excellent resources for those hoping to grow purely organic and these are available for easy purchase online.

Having made your mixture, inoculate it with rain and turn it every few days over the next 2-6 weeks. This will compost the soil, a very important step because, without properly composting this mix, you will burn whatever you put into it. Once ready, this is the best soil you will ever use. It will only require water and the odd tea, and it can always be recycled with just a few simple amendments.
