Indeed, indoor growing of cannabis brings you great satisfaction and joy as without worrying about weather and climate conditions, you can enjoy the yield year-round. But still, need to consider some points ahead of growing marijuana strains indoors.

Before taking up our best-performing indoor strains, you need to know the factors that seriously affect your crop. Every indoor grower should take care of these factors to have bountiful yields.

The genetics:

The most definitive factor is the genetics of the strain. It would be best to take up the strains with a strong lineage. No matter how much effort you are putting into it, strains with weak genetics would not help you with yields. Some plants can yield up to 800-900 gms while others 300gms indoors.

Gender:

You must pick feminized seeds for heavy yields as only these seeds can produce dense and potent buds. If there is any male plant inside your indoor garden, it is recommended to take it out before pollination.

Grow Lights:

We know that grow lights play a vital role in the growth of indoor marijuana plants. If growing outdoors, plants do get plenty of sunlight to thrive. But, indoors, you have to manage everything for them, incredibly the light.

Make sure you are using the best grow lights for your grow space.

Temperature and ventilation:

Like the grow lights, ventilation of the grow space and the temperature in the grow tent decide the yield.

If you choose the highest yielding strains and are still not getting the desired result, you must check your lights, ventilation, and temperature. Every step is crucial if you grow indoors.

Further, your space should be airy enough to maintain the optimum heat and temperature. You must keep a close watch on the plants’ heat at every stage and adjust accordingly.

Water, Soil, and nutrition:

Plants will thrive if they get what they need. Please check the requirements of the plant and feed it according to them.

Remember that overwatering over nutrition can damage your plants more than the
lack of these essential elements.

If you keep these factors in mind and then look after your indoor plants, your indoor-growing cannabis strains will yield better and more potent weed plants.
