Ok folks here is yet another DIY tutorial that ill repost in the DIY section, but this is part of my journal so it will be in my journal also also

How To build your own Ebb and Flow system with height restrictions

How it Works:
This setup is designed for a room with not much vertical space. One of the main rules of thumb for hydro systems is that the basin must be higher than the reservoir level. With this system they are stacked right on top of each other. So, water is pumped from the bottom into the top until it reaches a level, in which it is drained back to the bottom, the same line it came in on. The pump will be linked to a timer so the system can fill and drain 3 or 4 times a day. You are also going to want to have a cover so no light can get in and build up algae, it is clear for the purpose of this tutorial.

You will need;

2 Male quick connect garden hose couplings

2 Female quick connect garden hose couplings

5 Feet of 1/2" inner diameter tubing

1 Roll of Teflon Tape

2 1" o rings

2 Underbed Storage bins
Found this one at target

1 ~100GPH pump

1 Tube of Silicon

1 24 Hour timer

You will also need;
A powered Drill
A 1" Drill bit
A knife
Channel lock plyers

Lets get Started!

1. Mark where you are going to have your exit and entrance holes.

2. Cut those holes out, and Drill with your 1" bit where you have your marks. Careful with the drill, one slip and you might have to buy yourself another storage bin.

3. Line both Male couplings with teflon tape, and apply silicon to edges.

4. Turn the bin over and screw in both male couplings so that the adapter end is coming out of the bottom of your basin bin.

5. Screw on one of the female couplings to one of the protruding male ones on the inside of the basin. Then cut a piece of tubing so that when it is set in place, water will overflow at the opening of the tube.

6. Attach a hose from the other male adapter (that doesnt have the overflow extension on it) to the pump that will sit inside the bottom reservoir. And stack your 2 bins so that the entrance and exit lines run through the precut holes you made on the lid of the bottom reservoir.

7. Fill the bad Boy up with water until there is enough water to keep it cycling from the bottom to the overflow and back and fourth. Youll see once the water reaches a level, it will drain back to the bottom.

8. When you want to drain your system, attach a hose to another female coupling, and screw it on to the entrance line of your basin, which will bypass the filling of that, and send it straight to a bucket you have prepared.

hey, imagine your whole flowering chamber was about the size of one of those bins, ok, where would you put the reservoir? in another exact the same bin underneath? how frequently must the mixture be changed? and what growing medium do you use?

thanks
