The benefits of growing cannabis indoors

Growing cannabis seeds indoors has countless advantages


  • You'll have full control over the environment and the production process (temperature, air circulation, humidity, and light).
  • When harvesting, you can expect half a pound every two months depending on the strain, even though indoor plants tend to be smaller.
  • Indoor plants are less prone to being attacked by pests and mold, unlike outdoor plants.

Multiple marijuana harvests

There are two ways to achieve multiple harvests out of your crop. The first is known as perpetual harvest, an indoor cultivating strategy that simultaneously uses two different grow rooms. 

There are consistently crops from indoor weed seeds in both the blooming and vegetative stages. This method is common as it ensures a continuous supply of cannabis. 

The other is re-vegging or, better yet, regeneration. It’s a process where you manipulate your plant's light cycle after its first harvest. It encourages your plants to revert to the flowering stage and produce a second harvest.

It’s a method that ensures about 1–3 harvests with high yields if done correctly.


The disadvantages of growing indoors

Indoor growth operations generally have high running costs and obtaining equipment usually requires an initial investment. They also require water and electricity. Growers spend a substantial amount of money on utility bills.

In some cases, improper ventilation can pose a major health hazard due to elevated CO2 levels.

When it comes to growing indoor marijuana seeds; you’ll also need:

  • Lighting: You’ve got the choice of LED or HiD lighting; both offer their advantages. HiD lights are less energy-efficient, whereas LED's have better quality.
  • Grow Room: When deciding the best location for your setup, size matters. Though it all depends on the type of strain you want to cultivate. Water supply,  electrical, and roof height ensure the perfect growing environment.
  • Soil and fertilizers - Marijuana producers need to understand that utilizing the appropriate supplements maximizes the flavor. It also improves the quality of your smoke and guarantees that a high-end product is grown from your indoor weed seeds.
  • Ventilation - Appropriate ventilation stabilizes humidity levels and eliminates CO2 drained air, keeping your grow room at the perfect temperature. Inline fans make growing indoors less strenuous and more productive.


Selecting your indoor seeds

When you decide to cultivate cannabis indoors, you have to decide between indica, sativa or hybrid strains. You also have to ensure that the seeds you select are of high quality. The best way to make your selection is by using a reputable seed store. 

When you browse through the SeedSupreme site, you’ll find a variety of premium indoor weed seeds. Each product has an information page with the relevant strain details and cultivation tips.


Indica seeds

Indicas are fairly short and stocky plants making them perfect for indoor growing conditions and a great choice for first-time growers. Many use these plants both recreationally and medicinally. 

Indica marijuana plants are known for their relaxing effects, leaving users sleepy and in a deep body high state. Also known to relieve symptoms associated with disorders like anxiety, insomnia, and appetite loss, to mention a few.


Sativa seeds

Sativa plants raised indoors from marijuana seeds are tall, thin, and take longer to mature than their indica counterparts. Found in predominantly hot, arid climates such as Central America and Africa.

Sativas have a low CBD content with high THC levels known to produce a head high and reduce anxiety. Other effects include increased energy, making this the perfect bud to smoke before going out or doing something productive.


Feminized seeds

Feminized seeds are a popular choice amongst growers, especially novice growers, and here’s why.

  • They’re the best marijuana seeds for indoor growing and producers who want to limit work input while boosting crop yield.
  • Fem seeds are perfect for newbie growers because they only produce female plants. You’ll never have to be concerned about male plants spoiling your crop.
  • These seeds have more significant yields per unit area with no risk of seed production.
