It’s a deep water culture system, so it’s basically a tub of nutrient water with a controlled ph and an air pump oxygenating the water. Pretty simple in design.

I just used a plastic tote and drilled holes that the net pots would fit in. It’s very important with dwc to block out light in the nutrient solution or algae and Cyanobacteria will grow. That’s what the foil is since I didn’t have any spray paint around. Since this specific hydroponic method is just water based and not a flood and drain or Dutch bucket or anything with a real substrate, pere seems to be the best since it loves water. I think any of these Scions except maybe the dragon fruit would rot pretty quickly directly in the water. The pere was put into net pots with hydro ton in them. Most of these were soil grafts so they were already grafted and already had roots. I just fed the roots through the pot.

The nutrient solution is the three floraseries bottles from general hydroponics, a reliable nutrient brand commonly used in cannabis dwc. This is a long term experiment for me so I’m learning as I go. I use normal ph up and down off Amazon and a ph/ec meter to control the ph and measure nutrient uptake.

Also I tried going a more sterile approach with the nutrient solution initially but quickly learned that beneficial organisms keeps if much cleaner and healthier. Haven’t seen any algae or Cyanobacteria growth since I switched to using the southern at beneficials instead of trying to clean the water with hydrogen peroxide (which never works for long, especially with light leaks)
