Ok this is what I'm making.
The extras I'll need, 3/8 inch tubing and 1/4 inch tubing, some 1/2 tubing for water level marking, 3/8 inch 90 degree elbow, 3/8 inch T, 1/2 inch groument, some masking tape, 4 inch long screws, and some quick ties. Also 1 inch uptake tubing from a pet store.
Tools needed, scissors, sawzall, drill with 1 inch, 13/16th inch, 1/4 inch and 7/64ths inch bits. And screw driver head.
I'm using 2 of the oversized kitty litter pails that come around here now. I measure down 5 inches all the way around on one of 2 pails.
Sawzall works best starting at the corner first, make it as even as possible.
You can see how it will eventually sit about an inch lower than a normal waterfarm, holds 3 more cups of grow rocks, and 3 gallons of water now instead of 2.
The bottom that was cut off the one bucket is then placed inside the top and moved to the bottom to be even, then 1 inch screws in each side. I should use galvanized, but don't have them around.
So now we have the bucket part ready to be finished.
Flip over the top bucket part, and in the middle top, drill a 1 inch hole. This will be for the uptake tubes to keep them away from the grow rocks to be able to clean during their growing.
Then drill a bunch of 1/4 inch holes for the nutrients to drain to the resevoir. Drill from the bottom up, to help with the roots coming thru these hole to easily, they will anyways, but just backup if a salt builup or something you didn't notice.
Now to the un-touched bucket, I drilled a 13/16ths inch hole on the skilly side in the middle.
Here's the parts I'm using. 14 inches 1/2 inch blue tubing, 90 degree elbow, and groment, all 1/2 inch.
The groment, you have to work in with a spinning motion, hand inside and outside of the bucket, but make sure it's seated properly or it will leak.
Then take the elbow and holding the groment on the inside, work it into place facing straight up.
Connect the 14 inch piece of blue 1/2 tubing, drill 1/4 inch hole to put the tie thru, but don't snug it up, you want to have it be able to come out for changing. Then mark 5 inches down, and that's your level mark.
I want a 14 inch piece of uptake tubing, I wrap in masking tape to help with splintering and then sawzall it.
I'm holding the dark normal waterfarm uptake tube, and you can see how I've cut the bottom to allow for water to enter it easily.
I cut the end of a piece of airline tubing 14 plus inches also.
This is what I'm making with 3/8 inch tubing and 1/4 inch tubing, this is a waterfarms uptake tube.
And what I do, drill 1/4 inch hole for air line tubing to go into, cut the bottom of 3/8 inch tubing at an angle also.
The 3/8 inch tub should be 13 inches long, the one end cut at an angle with the airline, the other end is the top and put the 3/8 inch t into it well.
I use 21 inches of the 3/8 inch tubing for the drip ring, I've modified this too to also have a cross member, but for a basic one 21 inches works well, then drill holes every 3 or so inches around it, the small drill bit.
I also cut off 1/2 inch from my waterfarms airline, and use this piece in my new waterfarm so that 1/4 inch airline hose will hook up the the 1/4 inch line I used on it.
Well hope this works, took forever and I'm sure I'll be correcting something, but gives you the main idea for one.
