This is what held me back when I first started………I looked at a bunch of pics on line and pieced together something in my head that I thought should work…….and It did……I’m coco dtw and I have to deal with 10gal of water a day, when I had my 2.5x2.5,4x4,4x8 all flowering and maxed out I had to deal with 25 gal of run off every day…… this system is not the prettiest. but I’ll tell you what….this shit works bro lol…… take a wire rack remove a shelf. place it on top of a 3 x 3 flood table, that’s it lol…… I bought a $20 bottom suction pump off Amazon very important that it’s a bottom sunction and not a Side suction that way you get the most water out…… however I’ve noticed it’s a lot of water in that flood table it helps drop my note temps down by a couple degrees with all the air movement kind of like Lake affect cold fronts…….hook a black hose you would get from a hydro store on the pump and leave it under the wire shelf so when u need to drai it just plug it in and fill up 5mgal buckets boom it’s that easy……I’m lucky I have a floor drain so I just plug it in and walk away. I have a smaller tray on other side because it was cheaper and I like being able to move things around so I dropped a cheapo 2 foot by 1 foot wire shelf in their and that’s what she’s sitting on I hav e a cheapo pump in that one with a hose leading into the big one
