another dwc/bubbleponics diy build. PICS

hello everyone. please do not post until you see the devil!

here is a dwc/bubbleponics build i am doing from information on this site, and other sites. it will be my first dwc grow. i am waiting for my clones to root. thanks for watching, hope this helps someone.

make sure your res is light proof! very important for healthy clean roots......

well here are the net pots. i think they are 3" diameter. the tub is 16 gallons. i used a knife to cut out the holes, took a lil while.

here is showing how i ran the air lines to the airstones, and also how i placed my water level indicator. tomm, i will add the drain valve. until then go ahead and post if you like. who am i to stop you. any advice or questions would be cool. i was wondering id i should use my water pump to run a water to the net cups too? or just add water until they reach the bottom of the net cups, and top feed until the roots have reached the water level?

i was going to use a valve for the drain and place it as low as possible, but since i have height restrictions it will be hard to place anything under the darin to catch the water. maybe i can use my water pump? is there a way to reverse a water pump so i can keep the pump outside of my res? just dont want roots beight entangled, or sucked into pump.
