Problems Caused By Overwatering The Cannabis

Both overwatered and underwatered cannabis plants will cause issues, and you must keep an eye on their water levels. The drainage system, soil used, and the location where the plants are kept play a crucial role in their water consumption. If you get an adequate amount of sunlight in your home, the plants must be kept out for a few hours of the day to increase their photosynthesis process. If you’ve grown it in indoor lighting, keep it there only, as changing the light source can directly impact its growth. Here are some of the major problems that overwatering cannabis plants cause.

Moulds – If you’ve overwatered your plants, then it might create moulds on the leaves and strains. It can be really harmful to consume such plantations, and it might affect the growth of the plants. The major concern here is real health issues like skin irritation and lung cancer.

Twisted Roots – Roots are the most important part of a plant and play a direct role in its growth until death. If your plant’s roots have started breaking or are being twisted, then there’s something wrong with them. Overwatering, poor drainage, and the wrong type of soil can be a reason behind that.

Yellow & Brittle Leaves – Edges of the leaves of a cannabis plant might turn brown or yellow in colour because of both overwatering and underwatering. You can check the soil where you’ve planted your plant, and if the soil is wet, then it means the leaves are getting brittle because of excess water.

How To Water Cannabis Properly | Cannabis Watering Guide

If you are new to growing cannabis plants, then it is really important for you to know how to water plants properly. Remember that a plant’s life is divided into 4 different parts; Gemination, Seedling, Vegging, and Flowering. A dedicated plan and watering routine must be followed to ensure the proper growth of the plant.


When you’ve just soiled the plant or seeds, either put the seeds between two paper towels so excess water can be soaked easily. Once the seeds start sprouting, you can transfer them to the pot and repeat the same process there too. Use a good planter with a drainage hole beneath it from where excess water can be removed automatically.


Once your plant has started growing, keep using a spray bottle to water it. Pouring water directly with a can or jug might overwater it. Also, you must prefer using clean water and not from a general tap to ensure the best growth of your plant. Do not touch or move the plant for 5-6 weeks after plantation to keep it secure.


When your plant has a few inches in height, it is growing at a good pace, and now you must take care of the soil and water combination to give it a growth booster. If you want, you can add some pesticides and nutrients to the soil and regularly water your plant by keeping it in the sunlight for a few hours every day.


So, if you have reached the last stage, “flowering,” then you can pat your back as you’ve done a good job by not overwatering the plant and keeping it safe from other calamities too. At this point in time, the plant’s leaves can get dried, so water your plant by mixing hydrogen peroxide in it to give it more strength.
