Hey, iv grown DWC since i started growing and had amazing results im always gonna have DWC running in my room, be warned tho when done correctly the plants get BIG and bushy. Yes you will always have the bubbles running 24/7. You will water from the top down the clay pebbles for the first week, while the water level is just on the bottom of the net pot. Continue to water from the top down until you will see roots sticking out of the bottom of the net pot into the water. When your roots are long enough you can lower the water level to a few inches below the net pot, the gap between the net pot and the water level will have oxygen which the roots will love and give you better growth. When your in the top down watering phase just have a clear plastic dome sat over the top of the plant to stop the clay pebbles drying out coz they dry out very quickly without them. Then the rest is easy just change bucket every 2 weeks maximum, if it drinks more and needs topping up just top up with ph'd water until you are ready to change the bucket again. I have best results with a ph of 5.8. If like mine when nearing your last few weeks they can become to big to pick up and change the bucket so you will have to just top them up or get help but even with help it can still be damaging eg branches snapping etc aint happened yet but hell i panic when i gotta pickup a 5ft plant by a bucket lid and have to move her about not good. Get it right and you won't go back when you see what DWC can do. Nice1
