You also run the risk of having bugs move into your grow room. Insects larvae like moist mediums. If your soil never dries out, bugs will move in.
It is very difficult to over water when growing weed in coco. The coco doesn’t hold as much water as soil does. It runs straight through just making the medium damp. You can water every day in coco, and still not suffer from over watering.
Over watering your cannabis plants will have an effect on their whole nutrient uptake. Your plants growth will be diminished, and your plants are prone to getting mould and rot.
Using an air stone will allow plenty of air can get to the roots. If your plant is showing symptoms of over watering, in hydro, there may be an issue with your air stone. You should check for blockage, that are preventing air getting to the roots.
On the other hand, if you do not water your cannabis plants enough, the medium will become too dry, and good bacteria will die and not be able to live in it. It is a fine balance, which takes practise to get right.
If you get run off after watering, remove it. Do not let your plants sit in wastewater as this will also cause over watering too. Remove run off immediately after feeding/ watering your plants.
Most cases of over watering, will be with weed plants grown in soil. Soil retains water for a lot longer than coco, so less air can get to the roots. If you do not let the soil dry out between watering, the roots can’t breathe.
The symptoms of over watering a cannabis plant will display for a number of reasons. The roots of a marijuana need water and air in order to uptake nutrients. If you water the plants too much, your plants will not be able to absorb these things effectively.
If you over water your cannabis plant, the bacteria in the root zone will also not be able to breathe. This will cause a rise in bad bacteria, which will bring on root rot.

This sick marijuana seedling has several symptoms including droopiness and leaves with brown spots that appear to be a nutrient deficiency. Surprisingly, the true cause of both problems actually is the thick, wet, muddy soil.
Cannabis plants use their roots to get oxygen, almost like they’re breathing. Oxygen is dissolved in water, and there’s also air pockets in their grow medium to provide a source of oxygen. When you water your plants too often, the roots end up sitting in stagnant water. The reason your plants droop is because basically their roots are starving for oxygen.
This cannabis plant has green healthy leaves, but as a result of overwatering it’s stunted and small even though its more than a month old.
Overwatered cannabis plants are droopy with leaves that curl down. As a result of overwatering, leaves often turn yellow or show other signs of nutrient deficiencies (especially when it comes to younger plants and seedlings!)
How to Water Cannabis Properly
Overwatering does not always mean you’ve been giving the plant too much water. It can also mean that you’ve been giving the plant water too often, or growing plants in a growing medium that holds onto water without enough air, or doesn’t have good drainage out the bottom.
The main sign of a cannabis plant being overwatered are the droopy leaves, though other symptoms often appear around the same time!
For your individual growing medium and environment, your watering method will vary, but if your plants are drooping and you’ve been feeding them a lot of water, it’s a good idea to cut back and see if that helps.
Whenever a seedling has droopy leaves, it means that the roots are either not getting enough water (underwatered) or not getting enough oxygen (overwatered). This seedling has been chronically watered too often, preventing the roots from getting enough oxygen. As a result, the seedling has stayed small and mostly stopped growing.
Overwatering and underwatering cannabis plants are easy to do and can cause multiple symptoms including slow growth. Learn to recognize and fix these issues.
