Indoor Growing Cannabis Seeds

One of the first things growers figure out when meeting other growers is if they prefer growing weed indoors or outdoors. Since we are talking about plants, you can imagine that it is traditionally grown outdoors.

As the growing process evolved and we became aware of the specific requirements for weed, our thoughts turned to weed seeds for indoor growing. The control someone has in a room is an incredible advantage for growing an Indica which prefers to be cultivated in a temperate climate.

Be sure to only germinate high-quality Indica indoor weed seeds, like the ones you can get over at The Seed Fair.

What Are Indoor Weed Seeds?

Indoor weed seeds are the term that describes cannabis seeds that perform better when grown indoors. This can be for a variety of reasons:

  • The strain is sensitive to climate changes throughout the season
  • The strain could be susceptible to pest and mold problems
  • The plant may not grow properly in your area

Indoor strains have been selected from genetics that is supposed to grow well in small spaces such as cupboards and grow tents. For example, feminized seeds do very well in small spaces because they can still retain high yields while the grower does not have to worry if the plant is going to turn into a male and pollinate the entire area.

Autoflowers are also great as indoor weed seeds since they don’t need to rely on a photoperiod to transition to the flowering stage. They’re also ideal for those on a budget since autoflowering seeds require fewer nutrients than their photoperiod counterparts.

The Benefits of Indoor Growing Cannabis Seeds

Every method of growing cannabis has its benefits but growing the best indoor cannabis seeds comes down to how well you prepare. Here are some of the reasons why growing indoor weed is so popular and why it could benefit you.

You Dictate The Climate

Weed seeds for indoor growing in the USA are very forgiving to a budding cannabis grower. This is largely due to the amount of control you have over the environment. Your weed is at the mercy of the elements when you grow it outside, which can make or break a harvest depending on the weather.

With so many key aspects of growing weed relying on the climate, you can modify it to increase your yield. These aspects include:

  • Humidity
  • Temperature
  • Airflow
  • Light cycle
  • Water temperature
  • Growing medium temperature
  • Drainage
  • Nutrients

High-Quality Buds

The best indoor cannabis seeds will grow large, dense buds if they are given the proper lighting and nutrition. Providing strong enough light for photosynthesis and the right nutrients to develop those sugars for bud production is so big that they became two separate industries.

This is why you see massive indoor grow rooms that are pulling off hundreds of pounds of flowers each harvest. They have the lighting and nutrient regimen locked down for their specific strains.

Stealthier Than An Outdoor Grow

If you grow your weed out in your backyard, there is a risk it could get stolen. Sadly, this is more commonplace than most. The bright side is that it’s a perfect opportunity to try indoor CBD seeds growing.

Growing in your basement or a dedicated grow tent lets you control the smell and provide a stealthy way to grow weed outside the prying eyes of others.

Additionally, you don’t have to worry about the multitude of pests, fungi, and nutrient runoff from the soil that could potentially be problems for your crop.

Multiple Harvests Per Year

Outdoor growers only get one harvest per year (two if they cut the top buds off and let the lower branches mature). This means they have to grow multiple plants in order to have a substantial harvest.

Indoor grows give you an opportunity to have more than one harvest per year. More harvest means more bud to smoke.

The Minuses of Growing Marijuana Seeds Indoor

There are a few tradeoffs for growing indoor pot seeds that are often overlooked until it’s too late. While you will most likely see great success while growing indoors, here are some of the potential downsides to it.

  • Can be expensive (electricity, nutrients, and equipment)
  • Requires more attention and time
  • Sunlight is still the best light for growing weed

Is It Easy to Grow Indoor Cannabis Seeds?

The choice between growing your cannabis seeds indoors or outdoors is an important one, with both pros and cons. Growing your cannabis seeds outdoors is the least expensive option since the sun and rain are free. All you need to do is provide water and nutrients if needed.

Indoor cultivation gives you full control of your environment. This added control allows the grower to maximize yield and terpene production. The downside is that if something fails, it’s on your head. Having good genetics and a plan in place will greatly increase the success of your cannabis crop. When growing weed seeds inside these are the environmental factors you need to keep on top of:

  • Lighting
  • Growing medium
  • Water
  • Ventilation
  • CO2
  • Temperature
  • Humidity
  • Nutrition and PH

Once you have the basic aspects of a grow room planned out, it’s time to get some high-quality weed seeds from The Seed Fair and start raising your plants.

How to Grow Indoor Cannabis Seeds?

Growing weed seeds can be as simple or as scientific as you want it to be. Here are some of the top things to remember when growing the best indoor marijuana strain.

Start Off With Strong Germination

Growers always get excited when they see a strong taproot coming out of their seed. Soak your indoor seeds in a measuring cup of water in a dark place for up to 48 hours and you should see a taproot come out. Alternatively, you can lay the seed between sheets of moist paper towels and keep it in a dark spot.

Create The Perfect Environment

It’s best to mimic the seasons when growing indoor marijuana seeds. Start off with lots of humidity so that your germinated seedlings will have an easier time getting moisture.

As you turn to the vegetative state, you want to balance out the humidity and temperature to mimic early summer.

Flowering requires strong sunlight to develop dense buds. Lower the humidity to a little under 40% which provides optimal transpiration and water movement within the cannabis.

Feed And Train Your Plant

Providing nutrients that create the carbohydrates and sugars for dense trichome production is key to high-quality indoor weed strains. Low-stress training techniques can manipulate cannabis into building more main colas or multiple large bud sites. More trichomes means more flavor when smoking.

What Are the Best Lights for Growing Marijuana Indoors?

If you’re growing weed indoors, you need to figure out the best lighting setup for your plants. This process does require some research and a little plan to figure out the cost-benefit analysis.

Some growers use different lights for different stages, with many using a T5 at the beginning and then switching to something more powerful for veg and flower.

HID Grow Lights

HID lights come in a few different varieties that are usually switched between stages to take advantage of the spectrums. Many cannabis growers swear by these lights as the largest bud producers. The three types of lights that fall into this category include:

  • Metal Halide (MH) – Used in the vegetative stage since it has a lot of blue tones.
  • Ceramic Metal Halide (CMH) – Great for the vegetative and flower cycles. Think of it like an MH/HPS light on steroids, providing a varying spectrum.
  • High-Pressure Sodium (HPS) – Used primarily in the flowering cycle as it has a lot of the reds in the spectrum that cannabis uses to develop buds.

It is important to remember that these lights give off a lot of heat. Keeping your lamps far enough above the plants will ensure they don’t get heat damaged. A huge benefit of using HID lights is that if you’re growing indoors during the colder months, they will keep the ambient temperature warm without the use of a heater.

Fluorescent Grow Lights

T5 and compact fluorescent lamps (CFL) fall under this category of growing lights for weed. Most growers use them for germination and to help little seedlings grow into the vegetative stage.

Fluorescent lights are some of the most inexpensive to run and are easily found in local hardware stores. The amount of heat they give off is small, which makes them ideal for small areas such as grow tents or boxes. Burning your plants is unlikely using one of these bulbs.

LED Grow Lights

LEDs (Light Emitting Diodes) are the latest lights to hit the market and while they started a little rocky, they have since gained momentum and are commonly used in small and large-scale operations.

Their appeal lies in the low energy consumption and accessibility to the partial and full spectrum. The amount of light output is comparable to an MH or HPS but without the added heat that those types generate. With less heat coming from the lights, you have more control over the climate in your grow space.

How to Choose the Best Indoor Marijuana Seeds for You?

Not all indoor strains grow the same so it is important to do your research on how the plant will grow and develop in your space. At The Seed Fair, we give each of our strains a detailed description so that you can get to know the plant before you purchase seeds from us.

Specifically, pay attention to the following factors to make sure you pick the right seeds for you:

  • Plant height and size
  • The potential size of their yield
  • THC or CBD potency
  • Whether they are regular, feminized, autoflower, or fast-growing seeds
  • Flowering time
  • Potential terpene profile (taste and smell)

These pieces of information are key for getting the right plant for your garden. The last thing you need is to get a plant that is too tall for your space and won’t get enough light. Indica strains will grow low and bushy while Sativas like to stretch upwards toward the light.

Facts About Growing Weed Seeds Indoors

Growing indoor weed seeds is easy to learn but difficult to master. Good cannabis growers will tell you that you will never stop learning and the best thing to do is just to try. If you enjoy experimentation such as low-stress training, set aside a single plant to try it out on. Let’s take a look at some of the best tips we can give you from one cannabis cultivator to another.

Don’t Overfeed Your Weed Plants

Pumping your plant full of nutrients will often cause more harm than good. Some growers think that the plant doesn’t have a ceiling for tolerance and before you know it, you start to see some leaf burn. Pushing your plants a little is always good for trichome production but most generally stop once they see tip burn.

Don’t Skimp on the Genetics

High-quality genetics make all the difference in growing your weed indoors. Having bad genetics in an optimal environment will only produce mediocre plants. However, if you have top-quality phenos, then you will produce the best bud possible as the pot plant has incredible genetic potential.

Keep the pH of Your Water Balanced

If your water is not pH balanced, then all kinds of problems can start happening. Cannabis roots will stop functioning if pH goes below 5.5 or above 7.0. Once this happens, nutrient uptake becomes hindered and the plant will slowly start to die. If you’re using soil, ensure that you flush the growing medium properly to ensure there is no residual pH within the pot.

Fix Problems Quickly

Noticing a problem and leaving it for a few days is never a good thing for your weed plants. Nutrient issues should be addressed quickly or they can progress into something detrimental. Bug problems can proliferate at astonishing speeds, spider mites in particular can devastate a garden within days if not taken care of.

Always Take Notes

Every growing experience will be different and that is why taking notes is essential. You will more than likely come across a problem or trick that you’ve used in the past which will apply to future operations and having detailed information is important to remedy. Some people create a growing board in their room or space and mark down vital information pertinent to whatever week the plant is in. In the end, they take a photo of the chart, wipe it, and start over again.
