I know I’m guilty!
You may be too, of over watering your marijuana plants.
I’ve watered my plants to much on several occasions.
But don't worry, there are many ways to get out of this mess.
So let's save your plant's !
- Fact: One of the most common problems when growing in soil is watering too frequently.
Over watering marijuana can happen to anyone especially if you are new to growing.
Even experienced growers have this happen to them from time to time, although some may not admit to it.
If you're not careful it’s not good for the plants and it also becomes an excellent habitat for root aphids.
Watering your plants too much can lead to mold buildup and also result in a perfect place for fungus gnats to thrive.
They love the damp top soil or medium and rock wool.
Try and use about an inch of sand on the bottom and top of your grow medium of soil or coco coir to prevent an infestation from a lot of root eaters.
Here's a quick look at to what happens when you water your plants to much.
But seriously though it's when you suffocate your plant's roots with water because plants love oxygen.
If growing in soil or coco coir you can disturb the little air pockets in the soil or coco with too much water according to Colorado State University.
This can be the case when you grow with hydroponics you can encounter root rot from not allowing ample oxygen to hit the roots.
Signs of Over Watering
Your leaves should have the texture of paper. Feel them are they firm? Not weak and limp.
How to Fix Over Watered Cannabis Plants
Stop watering and let the plant dry out. Not completely( this will damage your roots) but close to it.
Go longer in between watering
Stop watering so often (this is usually the cause).
Place a towel or newspapers or flyers under the pots drain holes to soak up excess water after all the runoff finishes.
May need to drill extra drainage holes in pots with soil if not getting proper runoff.
Make air holes in the top of soil or coco coir with chopsticks (beware you open the gates to gnats).
Increase the heat slightly in the grow area a degree or too.
Bring in an extra fan.
If growing in soil remove from current pot and place into a slightly bigger and or same size pot or fabric pot to aid in drying it out faster to save the plant.
Add one if you don’t have one yet. It's essential !
Warning : It may be too late already.
Even if you try some of the solutions, it's all up to the plant on if it wants to or can recover.
Some genetics are weak and are not strong enough to recover from watering too much. It's when the plant has reached extreme stress.
I have seen both over watered, and under-watered plants recover. Until 4-7 days later just slowly start to die.
It's mainly due to root rot.
Be positive! Usually, you will catch this before it’s a major problem.
That’s why you're here.
Ways to Prevent Over Watering Marijuana
Soil or Coco Coir:
- When growing in soil make sure you have a high drainage soil such as Promix or Happy Frog.
- Add perlite if your soil doesn’t have it already or coco coir 1-4 ratio both are great for drainage.
- Do not saturate the soil when transplanting or planting.
- Try Smart Fabric Pots.
- Drill extra drainage hole in the bottom of pots.
- Use a Water Meter or Moisture Meter in soil or coco if needed.
- Use the finger method by sticking your finger in the soil about an inch to see if dry.
- Avoid vermiculite it helps to retain water.
- One trick for soil so you do not over water is to take an empty pot and fill it with soil and use that one as a test. Check when to water by judging by the weight of your plant compare to the pot of soil.
Hydroponic growing, just keep a good air stone or air pump at all times !
Have proper ventilation to help the plants breath and release their moisture build up.
Use a calendar for your water and nutrient feeding days; you may have to adjust as you go.
A good rule of thumb is to always check if your plants need water and not just assume they do.

Over watering your marijuana plants happens the most in soil.
When you grow in Coco Coir hydroponically or running a hydroponic system it's hard to water to much but is known to occur on occasion.
Remember there is nothing wrong growing in soil. Many growers prefer this method for the flavor and watering less often.
Where with hydroponics you run one to two times a day with a watering schedule.
Hopefully, this helps you get over this issue, and you save your plants.
