Watering Your Cannabis Plant

THE IMPORTANCE OF WATER QUALITY

Watering is important for marijuana plants for obvious reasons. What may not be so obvious, however, is that the quality of the water is equally important. It makes a big difference what city you are living in and how your city specifically treats its water. There may be more chemicals in your water than in a neighboring city’s water.

Regardless of where you are located, you will likely have some chlorine in your water. It isn’t a very healthy additive to marijuana plants. Luckily, chlorine is quite easy to get rid of. You just need to let the water sit for 24 hours or more, with the container holding the water open to the air around it. This will also ensure that the water becomes the same temperature as the room. Watering plants with water that is room temperature is healthier for them than shocking them with ice-cold water.

QUANTITY OF WATER

The next thing to consider is the quantity of water you are feeding your plants. If your plants are growing in a container that holds three gallons of soil, then up to three quarts of water can be given to them. The key is to observe how the soil is in terms of its moisture. You want the entire soil to be moist evenly — therefore it is better to water a larger amount once in a while than to water a small amount more often. If you only give your plant a little amount of water, the water won’t make it all the way to the bottom of the soil and the roots at the bottom won’t get any water access.

DRAINAGE

When watering your plant in any amount, you need to be entirely sure that its container has proper drainage holes at the bottom. You should see the water coming out the bottom when you water your plant. If this doesn’t happen, it either means that you aren’t feeding it enough water to reach the bottom or somehow the water is getting caught inside the soil — and that can lead to significant health problems. If the soil has sand and perlite in it, it is unlikely that it will have drainage issues.

Check the soil to see if it feels moist. If it does, don’t water it yet — wait for one to two days before watering again, because even when the top feels dry, the bottom of the soil may still be moist. Never water your plants when they don’t clearly need to be watered, as that can lead to overwatering issues.
