My grow area is 25'by 19' roughly. pretty much sliced it in two 1/4-3/4 to get a perpetual harvest going. i was thinking about building a DIY RDWC System. Im technical individual so its not to difficult for me to build something like this. i was thinking making a 8x8 ebb and flow table but use it as RDWC. Build the 8x8 table out of wood 4x8 sheets of play wood im thinking 1/2 inch should do and support rafts and legs under it to support the weight. Maybe 4ft on center rafters /legs should be plenty for sturdiness. as far as the exterior wall im not sure if i would go with 2x8s or 2x10s the bigger i go the more gallons il have to supply. 2x8s would require roughly 117.803 US gallons well id shave 10 gallons or so so i wont flood my floors lol. my top cover would be a pvc viynal material 1/2 thick 4'x8' sections. 3 inch or 6 inch net pots 9 per sq or 4 per sq if im really throwing caution to the wind HAHA . I would lean towards the SOG style due to my ceiling height is only about 8 ft. as far as the plumbing i havent worked that out yet and size pump for this but i believe a 1200 gp should be sufficient. id probably also plumb a water fall/ drip system in tandem with air cans at the bottom of the table spread out strategicaly to help with oxygon. id rather have over kill than not enough. since im building it my self i can fine tune the little things. with such a big table i dont think a 3 inch return would be feasible i doubt i would be able to keep sufficient water levels if its gettin pulled back to res that quickly. maybe i would have to use two diffrent res one for the drip/ spray system and one for the table its self with passive flow. building it is easy but as you can see its alot of unknowns as far as how the water will act in such a large grow area. id love to get input from you guys regarding this. Oh this is my first post im new here just call me BPR Aka BluePowerRanger Baby :-)
