Where do we begin?
I've been wanting to post this update as I went so that it wasn't such a massive undertaking when I finally did.
But there's just been so much going on I wanted to get to a point where I didn't need to do anything else.
So things look a little different in just a couple of days. The easiest thing to note is that we are 6 of 6 from green point with everything having come up above dirt as of 11/29.
The coffee crisps just opened their cotys today and are pointing to the light.
The most notable change is that after seeing and hearing all the talk I figured why not see for myself the results from a
SIP.
I love a good DIY and this one was very fun to do.
I followed a couple of different designs to come up with my application, but the principles are the same none the less.
Space is always a determining factor. For this grow I planned on flowering in 3-gal pots max.
So having a 5-gal sip wasn't really ideal for this sized grow.
This drove me the DIY route as a lot of the inserts i saw for sale were for 5 gal buckets.
Alot of the info I found was some sort of 5-gal. Big thanks to
@Azimuth for his thread and post on how to make varying sizes.
I'm sure the info was out there but tested results from a trusted member spelling it out for you.
It doesn't get any better than that!
I went with the 2.5-gal bucket from HD.
Originally, I purchased a 1-quart cup but struggled to wrap my head around an idea that I was so sure of when purchasing everything.
This made the bucket super tall and so I hit the drawing board again.
I found a video of a guy using a net cup as his void container.
and then sitting the bucket on top of turned over net cups to give support.
(Pretty sure I can find some of those in a bin somewhere)
Once we resecured our materials a dry fit of everything showed me that using net cups as support wasn't completely practical at least in my situation.
Another bong, another video, another idea!
Eventually my hands just couldn't stop
***********************************************SIP BUCKET*******************************************
First, I measured and cut the hole in the bottom of what will be our
top bucket.
I traced the net cup on the bottom of the bucket, then made a couple of marks indicating 1/4" inside the circle I traced. (Ignore the outermost line)
I didn't have a big enough hole saw with me so I made a few holes with the one I had and the carefully cut the rest of the way with a razorblade.
In the end you just want it snug so less is more.
Next, I measured the height of my net cup and cut that much off of my PVC. I then cut the piece in half lengthwise.
Next, Secure these pieces opposite each other in the bottom of the
bottom bucket.
I used a small screw and made sure to predrill the holes, so it doesn't crack the pvc.
Next, with the net cup in place slide our top bucket into the bottom bucket
it should sit securely at the bottom without coming up.
This next part was a little frustrating as I kept stressing about my measurements and not wanting to mess up.
(Using white buckets helps a little bit as your able to use a flashlight to see your markings through the bucket while assembling)
With the top bucket and net cup in place ensure that the net cup is sitting flush and measure 1 inch from the top of the netcup toward the bottom of the bucket.
Mark this height as you can see in the picture above on the
bottom bucket.
(Again, white buckets here help)
I used a 7/8 hole saw and made sure that the bottom of my hole lined up with my mark.
If you don't compensate here and put your bit on your mark, you will end up with a 1-1/2" hole and that will be too low for this to hold much water.
Before I started, I measured out 1/2 a gallon and a gallon and marked the lines on my bucket.
As you can see this will hold almost 3/4 of a gallon.
Next, using the 7/8-hole saw cut a hole just to the left or right of your air hole.
I believe in Azimuths write up it explains how placing this where to see when your bucket is full at runoff is helpful.
But I did mine upside down and put it on the left of the hole
So, this is a preference thing more than anything just makes sure you can see the air hole while you fill it up.
This part I incorporated directly from
@Azimuth
Cut a small piece of your PVC and place it into your coupling. 
Place this into the hole you just cut with small end down into the bottom and place your PVC pipe into the other end of the coupling.
The coupling blocks any dirt from falling through into your bottom bucket.
