@Mospeada, They look amazing. What model water chiller do you have? What temps do you keep the water at? My first grow was DWC but I switched to coco because of pythium and high humidity (no air con, no water chiller). I would love to go back to DWC but I don't want to spend money on a water chiller, and beneficial bacteria won't help when it's 32C outside.
@grower_not_shower, Mainly to increase the volume of the solution and the space for the roots to grow. Also it was just easier to make a system with 6 beds > 24 buckets.
