A common question is how often should you water your potted plants? Well, of course each plant is different and has different needs, but I will give some basic tips below and discuss watering systems you can use.
So how can you tell if your potted plant needs water? Well, you could use a water meter, and I actually recommend one. They are pretty cheap and a very quick and effective way to tell if your soil has enough or too much water content.
Another way to check is by simply lifting up or tipping to the side your container to see how heavy it is. Over time you’ll get a feel for how heavy it should be.
It actually matters how you water! It is better to under water than over water. If you under water, your plant will tell you by having limping leaves. But if you over water it can be difficult to get the excess water out. All you can really do is tip over the plant to get as much water out of the drain tray as possible.
The reason having too much water in your pot is a bad thing is because it will cut off oxygen to the roots and allow bacteria to grow. You need to have a healthy root system to have a healthy plant.
One way to do your watering is to have a 5 gallon bucket or so filled with water in your grow room. This will allow you to add a little humidity in the grow room, which can be very useful in the winter months when your heater is on and drying out the air. Allow the water to sit there for a few weeks, which will allow the chlorine or any other chemicals in your water to dissipate. Water each plant as needed with a watering can, and fill the bucket back up when you are done.
When you water, you want to make sure you don’t pour too fast and only in one spot. You want to gently water all over the surface area of the soil. If you only water in one spot, that is where the roots will grow, they won’t spread out. If you pour too fast the water will cause the soil to spread apart and expose the roots.
You could also use an automated system to water your plants. There are pots you can get that are auto water when your plants needs it. There are also drip systems that can slowly drip along tubes that your run off of a pump and irrigation. Of course these systems cost more, and with the drip system you could have a problem of the roots only growing where you water, as mentioned above.
