Hello, well I've just found this on another site and thought it would be quite useful for alot of people.

First things first: supplies.

1. (5) Drip stakes to hold the tubing and drippers.
2. (5) Drippers. My hydro store only had one flow-rate size (1 gph), but you can find others depending on your needs.
3. (5) Hole plugs (this is what your drip tubing will connect to).
4. (optional) Hole punch. You can easily just use a drill. I wanted to punch the holes to get a tighter fit. It's entirely up to you though.
5. 5/8" drill bit
6. Drill
7. Scissors or sharp utility knife
8. (7 feet) Flex tubing to connect your drippers to the main water lines. Not sure what size this was, but I'm guessing 3/16.
9. (5) 1/2" 90 degree barbed elbows
10. (1) 1/2" T-shape barbed connector
11. Submersible water pump. This one here is 120 gph. You really don't need much since it doesn't have to move a ton of water.
12. (8 feet) 1/2" ID (inner diameter) black vinyl tubing. This will be your main water lines.
13. (1 foot) 5/8" OD (outer diameter) black vinyl tubing. This will be used for connecting your pump to main water lines. I only needed a foot since my tray is low to the ground. You may need more depending on your tray height.
14. A large tray to hold the pots and water lines. I found this at Wal-Mart for $17. It's one of those "hide under the bed" storage bins that has the locking lid. You could just as easily use a common hydroponic table but due to space limitations this is all I could find.

Building time! Use the 5/8" drill bit to pop a hole in one of the ends of the tray. I made the hole a tad raised incase water runoff from the plants started pooling at this end.

Next, insert the T-shape connector into the hole from the inside.

Now, cut a small piece of 1/2" ID tubing and connect it to an elbow. You want to cut it in a way so that when you slip it over the T-connector, the two pieces just touch.

Next, measure a piece of 1/2" ID tubing to run from one side of your T-connector to one of the corners beside it. I was pretty stoned when I did this, so I just went by eye. Best to measure to be sure though Cut, and connect it to an elbow in the corner.

Here's a view of the tray with 1 gallon pots inside. I'll be trying this with 5 pots, although you could probably squeeze more in there if doing a SOG style grow.

Now we have to pop some holes into our 1/2" main water lines. For this, we use the hole punch, which conviniently has a spot for your thumb to really mash down to puncture the vinyl line.

Use a pot to line up where your holes should go. Because I have five pots, 3 holes will be on one side, and 2 on the other. The way I'm running my feeding tubes is to go across the middle of the tray to the other side, instead of having the feeding tube on the same side as the pot. Gives me an easier time moving them around.

Now we simply insert a hole plug into the hole and twist it until it's good and stuck.

Take one end of flex tubing (feeding tube), pass it through the hole in the plastic stake, and connect a dripper.

Bob on fella... cheers for that. "Cheep" just like the budgie.

Stick the stake/dripper combo into the surface of the soil and do a quick measurement to the hole plug. This is where having a pot of soil just for measuring makes things easier. Cut the feeding tube and stick the end onto the hole plug nice and snug. It should look something like this:

Repeat the process until you have all your feeding tubes and stake/drippers set up. Again, it should look like this:

The tray, drippers, and feeding lines are complete! Smoke break!

When you're done smoking that fine ganja, we now have to get a reservoir going. I didn't include this in the supplies list because a lot of folks have spare containers sitting around and in the end it doesn't matter what size you use anyway- just as long as it holds enough water for your needs.

Figure out where your pump is going to work best. For me, the orientation of the reservoir was horizontal, so the pump sits best right about here:

Next, drill holes with the 5/8" bit for your water feed and power cord.

What I did here was cut out the width of the diameter of the holes to make removing the lid easier once it's in the grow room. This is entirely optional. For me it just makes removing the lid easier than having to disconnect water lines, especially when the pump is running.

Ok, what I had to do here was a little jimmy-rigging. The 5/8" ID hose fits over the small, removable nozzle that attaches on the pump, but not snug enough. What I did was buy a tiny screw-clamp so I could attach the nozzle to the hose, tighten it in place, and simply put it back into the pump.

Into the grow room! Almost there! Place your tray onto your table or whatever is being used to hold it up, and place your reservoir on the floor infront of it. Stick your pump to the bottom of the resevoir so it doesn't move, connect your piece of 5/8" tubing, and do a quick measurement to the elbow. Cut it, and connect it. Note: it does not go on easy. I'm still trying to figure out a better, more secure way to attach it, but haven't thought of anything yet. You'll get to maybe the 3rd or 4th barb on the elbow. As long as there's no leaks when the pump runs, you're golden!

A quick look at the setup:

Next, we want our feedings to be on a schedule that matches the light cycle of your plants. Sync your pump timer with your light timer. The timer I'm using here has intervals of 15 minutes. I think even the standard 30-minute timers would work fine.

Fill the reservoir with water for testing. Before we add the plants back just do a quick check to make sure the fittings are all snug and there are no air leaks to be found.

Add your plants one by one. The dripper should hang right above the middle of the pot, spout facing down.

The End.

Hope everybody finds a good use for it
