Do plants really grow faster in DWC?
In any case, after about an hour, you should notice the pH stays more stable (and that’s the pH level you should pay attention to).
Top-feeding provides a very tangible benefit in the beginning of the cannabis plant’s life. Seedlings sprout and grow leaves faster in the beginning, but the benefits will definitely diminish after a few weeks. Once a plant is in ‘aggressive vegetative’ mode with a big root mass in the water, the effects of a top-feed will be practically nonexistent.
In a DWC system, the cannabis plant’s roots are submerged in a hydroponic nutrient solution/water. The plant’s root system is kept in place in a mesh bucket/net pot with hydroton pellets. The plants are usually housed in a self-contained and opaque container such as a bucket (at least 5-gallon).
What Are Hydroton Clay Pebbles?
When the plants are young, their roots won’t be long enough to reach the bottom of your reservoir. During this initial period of growth, it’s important to water your plants from the top.
Advanced top-feeding/dripping systems continuously trickle water over the young plant’s roots. After the plants’ roots have grown enough, some growers switch back to the original DWC set-up.

How It Works:
In DWC, your plant roots are grown in a reservoir of aerated nutrient water that’s been adjusted to the correct pH. The roots are allowed to hang with only oxygenated nutrient water as a medium in order to get the best access to water, oxygen, and nutrients. This allows your plants to grow much faster as a result!
Since your plants are their sturdiest now, this is the best time to learn how much nutrients they like. You can move closer to giving them the maximum recommended dose and back off whenever you see the tips of their leaves starting to turn brown or yellow. If this happens, empty your reservoir and fill it back with water and nutrients at the previous safe level. With that being said, it’s a good idea to grow by the “If it ain’t broke, don’t fix it” principle if you have some happy looking plants.
