Growing Weed Indoors: 10 Most Common Mistakes

Growing weed indoors may seem one of the easiest things you have ever done, but new growers usually face many problems over the course of growing their first cannabis plants. Here is a list of the most common mistakes almost all beginners make. If you take these things into account beforehand, you will increase your chances to successfully cultivate the marijuana you desire.

Growing Weed Indoors: 10 Most Common Mistakes

Telling Friends

However inspiring your plans of growing cannabis indoors may seem to you, there is no need to talk anyone about it. When you want to boast of planting high-quality cannabis in your house, keep in mind that even your best friends may inform the police. Try to keep it for yourself even if you want to hear advice on how to grow indoor weed. For the time being, marijuana is not completely decriminalized in many states of the U.S., and it is better to take precautions to ensure your privacy and security.

Using Bad Clones or Seeds

The final result of the growing process is more dependent on cannabis genetics than your efforts. Thus, try to find a reputable seed bank in order to purchase high-quality seeds. Check the entire history of the strains available in a seed bank, or do your own research before buying planting material.

Damaging Seeds While Sprouting

If you already know how to germinate seeds when growing marijuana, you should also keep in mind that this is a critical time for them. Try not to handle them when they sprout. Otherwise, you may put them at risk of improper germination, disease, and pests. Cloning may also bring you a lot of problems, and you should try to avoid touching plants while they are growing.

Not Controlling Indoor Environment

When growing cannabis indoors, beginners usually do not pay attention to the humidity and temperature recommendations. However, to create the ideal environment for your weed plants, you should take good care of everything. If you want to get the best yields of marijuana, try to establish the humidity of about 30-70% and contain the temperature within the range of 75 to 85 degrees. Moreover, when you grow cannabis indoors, you should also think about the proper ventilation to keep the indoor climate under control.

Excessive Use of Nutrients

When it comes to using nutrients, beginners usually try to follow the recommendations on the side of the package. However, most nutrient companies recommend to use larger amounts of nutrients than your weed plants actually need. Excessive quantities of nutrients can damage your plants greatly and even lead to a nutrient burn. In order to avoid this common mistake, check out our tips on how and when you should use nutrients or seek a professional advice online. Remember to always pay attention to your plants on a daily basis to control their growing.

Pouring Too Much Water

Though water is vitally important for your cannabis, you can easily damage your plants by pouring too much water into pots with marijuana. Hydroponic growing may be a good way to avoid overwatering. Thanks to the drainage properties of hydroponic systems, your plants will not suffer from excessive moisture. However, if you decide to use other methods of weed cultivation, the optimal option is to water your plants one to three times a day. Before watering, make sure that several inches of soil in pots have completely dried out.

Improper Use of Fertilizers

Nutrients are very important for marijuana cultivation, but it is crucial to use the correct type of fertilizer. When you begin to cultivate cannabis, you may want to use your old fertilizer from your shelf. It can really help your cannabis plants start to grow, but it may be not enough for them. Pay special attention to the labeling on the fertilizer, especially to the amount of nitrogen, and the recommendations on its use at the stages of growing and flowering. Following these instructions, you will increase your chances of having a more successful growth operation overall.


Pruning cannabis plants can stimulate their growth and increase yields greatly. However, overpruning can make your plants weak and even kill them in some cases. Read our article on how to prune marijuana plants to be sure that you do everything right.

Disregarding Growth Stages

It is very important to pay attention to the growth stages while cultivating marijuana plants. You will not get intensive flowering without proper vegetation. Make sure that the plant has enough air and space before inducing flowering. Otherwise, the plant may grow too large. Beginners usually need some time and experience to understand the growing stages and benefit from them.

Harvesting Too Early

Cultivating cannabis plants is a very fulfilling activity, but harvesting is the most desirable stage. When your weed plants start flowering, there is always a temptation to crop buds too early. But if you want to harvest the largest yield, you should wait until your marijuana has completely stopped growing and the white pistils on the buds have mainly turned brown.
