I'm currently in the final stages of building a cabinet from the DIY section, which can be found here: www.rollitup.org/do-yourself/9116-scrog-cabinet-part-1-a.html (basically a 250 hps cabinet with 4 compartments each 23''x27''x46'') In the instructions, the author uses an open flow system using 11 gallon rubermaids to hold the plants; this requires a res in a lower compartment. (FWIW, I can't find a 11 gallon rubbermaid container, all I can find is a 10 gallon like this: Storage boxes which is approx 9'' tall) I would like to do away with the res in the lower compartment. Would a DWC system work in a 11 gallon rubbermaid? Maybe aeroponics? What other forms of hydro growing would you recommend that would be short enough to allow me space to grow scrog in only 46'' of height?
