Are you Watering your Cannabis Plants Right?

Cannabis plants really do need a watering schedule to grow properly. There’s also a right amount and wrong amount to give each plant. Too much water can suffocate your plant and/or cause the plant’s leaves to turn yellow. This quick guide will help you learn how to properly water your cannabis plants when growing in your home (in states where it’s legal to do so).

Is your Plant Thirsty?

If you can put your finger more than an inch into the soil of your pot and don’t feel any moisture, your plant needs a drink. The soil shouldn’t be soaked, it should just feel damp. That is a defining factor as to whether your plant has enough water or not.

An inch of dry soil is okay, but should not be more than that. Keep a ruler in your grow. Put the ruler an inch into the soil, and then replace the ruler with your finger. If the soil doesn’t feel damp at that point, your plant needs a drink.

You’ll water less in the beginning than near harvest time. In the beginning, watering every other day is common. If possible, water every 3 to 5 days is best, but if your soil is dry you won’t want to wait until that third day.

Here’s a tip: Use a bigger growing pot. Those require a lower watering frequency. Seven-gallon growing pots are ideal for those that want to watch water usage.


Proper Nutrient/Water Mix

If you’re using a super soil or nutrient enriched soil, test your nutrient levels before adding additional amounts to your water. You may make the nutrient ratio too rich, which can cause problems for your plant that aren’t always fixable. When using nutrient mixes, make sure that you follow the directions exactly as given on the package. This means measuring the amount of nutrients and water before combining them to make sure it’s the proper ratio.

Proper Drainage

Your cannabis plant needs to be able to drain some of the water it’s given. You’ll want a 10 to 20-percent run-off when watering but no more than that. Use a container with drainage holes in the bottom and make sure you have some perlite or clean gravel at the bottom to ensure that the drainage holes aren’t blocked.

If you use nutrient enriched water, the runoff is important. Nutrient buildup is common in enriched soils, which can cause nutrient burn, mold and other plant diseases. Too many nutrients can also attract bugs to your plants.

Closing Thoughts

All plants need water to survive. Cannabis plants, however are a little different. They can go a few days without being watered, but still have to be monitored. You should never have a pool of water on top of your soil. That will likely lead to the death of your plant, root rot or a premature flushing of nutrients. There are no real measurements, such as cups or gallons, that your cannabis plant should be watered, it’s more about the feel of the soil than anything else. Once you master that, you’ll have harvests that are more successful.
