2 liter soda bottle aeroponic system?

I can't even remeber what the book was called but in it the people made a setup where water was piped in through pvc pipes, and out through sprinkler heads into 2 liter bottles that where upside down, with the bottom cut out and turned inside out for a cup to hold the plant. The idea being that the water would fill the bottle and water the roots and after the pump shut off the water would drain back down through the sprinkler head. It all seemed very complicated for what amounted to an ebb and flow setup. Anyone used it?

Also any recommendations for the ideal hydro setup. My grow space will be 3x3 x 5 ft high using a 400 W HPS and I would like to keep my plant # to 6. of course I want the most yeild possible, and also a certain degree of being foolproof. I am considering an ebb and flow, but a DWC seems so much simpler. Which has the better yield typically.

Flood systems with pots of absorbent media are dead simple- much simpler than DWC.

Skilled growers can get more out of DWC than floods, but just one crop a year lost in a DWC due to an air pump failure or long power cut (roots drown without constant air) would negate any productivity gain of DWC v flood.

If fault-tolerance, mechanical simplicity, reliability and low maintenance is what you want, a flood system is your pick. Only a wick system is simpler, with no pump nor recirculation of nutes.

just remember ya need a shit load of air flow in such a small area goa keep them temps down!!

cooltubes!
