The Basics of Watering

June 9, 2020

Watering is one of the most overlooked parts of the grow cycle. While it seems simple, watering is an art and is easy to get wrong. Many beginners over- or under-water their plants, increasing the amount of time it takes to grow. Knowing the proper watering techniques helps get you to a quicker harvest.

Types of Water to Use Growing Cannabis

Using the right type of water is necessary for the plant to get the nutrients it needs. Organic growers are able to account for the added chlorine in city water, but most growers should stay away from using public water. If you want to use it, always test city water before using it on your plants. Most people prefer using distilled water or, better yet, buying a reverse osmosis (RO) filter for clean, unadulterated water. Using distilled or RO water is a guaranteed way to make sure your plants are getting only what they need—nothing more. 

Everyone can benefit from testing the PH in their water, but this is vital for hydroponics systems. While soil has a buffer from PH fluctuations, hydroponics systems depend entirely on you to manage the PH. Ideally, your PH will test between 6 and 6.2 using a cheap PH meter. Products called PH up and PH down can be used to bring water within this range.

When to Water Your Marijuana

Knowing when to water allows you to speed towards harvest, as over- or under-watering can stunt cannabis’ growth. To judge whether a plant is ready, there are a couple of different methods. The simplest is to stick your finger in the soil. ALL the way in the soil. If the soil is dry, it is ready to be watered. 

The next method requires a bit of practice. Since water is so heavy, you can tell whether the plant is ready to be watered by picking up the pot. Do this regularly to get a feel for it. Try picking up the pot after it has just been watered and once again a few days later. See the difference? Eventually you will be accustomed to when the pot is empty of water. 

How to Water Medical Marijuana

Many beginning growers are surprised to learn there is a proper way to water. Since the strength of the roots helps determine the size and strength of the overall plant, you want a wide base of healthy roots spread throughout the pot. You can encourage this growth pattern by watering thoroughly. First, saturate the entire pot, slowly. Take your time here. You want some runoff from the bottom of the pot. Repeat this process again 30-60 minutes later.  

Watering properly allows thick, healthy root networks to form throughout the pot, creating strong plants and, eventually, the thick buds of your dreams. By continually improving your grow and learning from the best, you can grow like a pro in no time! Good luck and happy growing.
