How Do You Grow Dwc

DWC cannabis growing is done simply in a bath of nutrients with air bubbling through it. There is no grow medium, other than a small net of pebbles supporting e.g. a cube of fibre glass used for the cannabis seed to germinate in. Other than that there is just a light-tight bath/container for the cannabis roots.

How often do you change the water in a DWC system?

Therefore, every 1-2 weeks (generally the longest you should wait before changing your nutrient solution is three weeks), you should remove your plants from the reservoir to replace and refresh the hydroponic nutrient solution, then place the plants back in the reservoir.
