you can scroll down thar and see the basic lay out of a water culture system or (deep water culture), although you don't have to follow those build instructions, heck i didn't even need foam for floating, or an aquarium-- i just took a large Tupperware container (non see through), used a marker to trace my glad ware/Ziploc cups for the holes on the lid. Then made slices in the cups for the roots (but not too big so the fish gravel doesn't fall out), bought a fish air pump, an air stone, filled Tupperware with water, poked hole for air hose, connected air stone to end of hose after inserting the tube.
Filled my cup with gravel, and then placed seedling in cup (burying the root in the gravel), then put the cup in the hole where the lower half is submerged in the water
ah well crap im rambling on here like a moron..
anyway some people like to make it more complicated by buying certain meters and testers that measure how nutrient rich the water is after you've added your ferts, and the pH balance can also be measured by testing units, but these aren't REQUIRED. Although theres no argument that these specifics are important to know for superb growing as this is and can be a complex hobby but--
My friend and I both use dwc without any testing equipment. No more soil, no more constant watering, faster plant growth (most of the time).
I don't even use distilled water.. i use tap water from my sink haha
Infact i dont like the setup the greenmans pages actually displays in the picture.. having plants together in 1 unit is a bad idea, as ive done this before -- and the roots ended up getting so large that they started fighting, both females were trying to strangle one another as it looked, and both plants began to suffer and in the end, died.
-- you ever thought about taking 1 or 2 of your plants and transplanting them into an experimental DWC unit?
