CB-SCROG or Circular Bucket/Barrel SCROG Method
First off... I take NO CREDIT for the CB-SCROG Method... the people here at Barrel of Green are the ones responsible for the idea i'm having this.. morning? Yea.. It's 3am.. Great.... Anyway.. They get all the credit for coming up with this awesome idea... Also.. Credit for pictures and general know how also goes to BOG.com.. I'm just passing on the ideas to all of you lovely people... Only thing i'm taking credit for is the idea to implement the Odor Neutralizer into the loop 
Well... After posting a planning thread in the Absolute Beginners thread, which can be found here, I did alot more researching and reading. I started off by reading the thread on the Perfect Odor Neutralizer, here on this forum, and then the SCROG Method, also found on this forum, and lastely.. I found this little gem somewhere, and i'm sure alot of you who have been here a while already have seen this... Its called the Bucket of Green, BOG grow. Basically.. its a circular bucket SCROG grow.
It has pics on the site, although I found their Mini BOG, the more inspiring of the lot.
Now I haven't seen or heard of this done on these forums yet. So I figured I'd post this up as a sort of imformative/how to on the CB-Scrog method 
So here goes.
First off, the CB-SCROG method is a combation of the SCROG Method, and a Bucket growing system...
I drew an absolute master piece on MSpaint, havnt used it in forever but my artistic drawing came out immactulate 
Honestly.. I've never done a how to even using other resources so bare with me as I butcher this...
What you'll need:
1. 3 - 5 gallon buckets, or something similar. For the grow chamber, you want TWO containers of the same size so that when you set one over the other, they fit nicely and you can seal it with a piece of duct tape or just let them rest on top of eachother. The third bucket is for the "Air Neutralizer", found here. It will tell you what further materials are needed for that, although you can use any sort of container handy. Most buckets are 14.5" tall.. Making two stacked.. only 2.41ft tall.. Ideal for small grows, and secrecy.
2. PVC pipe- This will be used in the bottom bucket for fresh air to be brought into your bucket and Directly into/onto your plants. Again, on the top, to Draw the hot air(and smell) out of the buckets, and into your Air Neutralizer so as to keep your grow chamber cool, and the stench down as much as possible. You can see the PVC in my masterpiece as the Dark red lines(along with the hot air >_>) in the buckets. Also used as the light housing which will hold your lights in the bucket.
If using 80mm fans, the pip should be roughly 3in in diameter to provide optimum airflow.
If using 120mm, 4.5inchs would be fine.
You should measure your bucket and see how much room you actually want to take up with the PVC in the bottom bucket. As for the top, the sizes of PVC specified per fan size should be used for optimum exhaust through the top, and if using higher CFMs, and more airflow, might be able to create a small suction effect to keep fresh air drawing in through the bottom... But i doubt it 
You'll also want at least two 90* PVC elbows to be used as demonstrated in the masterpiece drawings.
3. Chicken Wire, or Tomato wire. - This will be used for the SCROG method of growing your plant inside the bucket. If your not familiar with the SCROG method, it can be found here. It will keep your plant low, away from the lights so as not to burn up, and keep your plant in check so it doesnt want to try and outgrow the buckets. Home Depot, Lowes, Wal-Mart, or any gardening store should have this, you don't need much, just check out the SCROG grow to get an idea and make sure it will fit below the rim, or about a quarter into the top bucket.
In the picture, I have my plant at about half of the way in the bucket... Should probably be about 3/4 filled with soil im guessing.. You experienced growers should be able to figure it out... As for beginners.. Probably 3/4 at the top of the bucket, that should leave room enough for the roots of a small plant or two, and the chicken wire sticking about 1/4 into the top bucket when the top bucket is on the bottom one.
4. For this drawing, I'm using at least 2 80mm computer fans for the flexible vent hose which i'll show you where to get in 5. At least two will be used for the hose between the top bucket and the "ONA" bucket. I'd recommend all 3 be computer fans, as they are silent and can still push alot of air. Being a computer "geek" also, it helps to know where to look, Newegg.com has some good ones, but I personally am going to be going between these two found at Xoxide.com:
UV Sensitive 80mm Fan with Four UV LED's (Orange) - Cheap, 32 CFM @ 2600RPM @ 30 dba - Rember.. those LEDS can alway be taken off so you dont have an annoying light all the time.
Enermax Marathon 80mm ENLOBAL Bearing Fan - For people who want VERY quiet, but at the expence of CFM... Not something i'd go with unless you need it VERY quiet.
80mm Sunon Tornado Fan - Powerful @ 84 CFM, but a bit noisy @ 5700RPM @ 55.2 dba
For those who want more powerful yet quieter fans, heres a couple 120mm. I might scrap the 80mm and just go to a hardware store and find Vent Ducting that will fit the fans. You may want to do this for more airflow, or do the 80mm if you dont care, or are too lazy to go to the hardware store and figure out what'll work 
Thermaltake Silent Wheel 130mm Fan with 120mm Fan Hole. 9.49
Aerocool Turbine 2000 Black 120mm LED Fan. 14.99
Or.. If you dont mind a little humming.. These tiny little fans push a whopping 89 CFM @ only 1800rpm @ 32dba. Still pretty quiet
Aerocool Xtreme Turbine 3000 UV Blue 120mm LED Fan 17.99
Best bet would be to do, 3 Aerocools with custom vent, but at $18 a pop, and having to make your own vent, thats up to you.
5. You can also go to your local hardware store and find drier venting. I'm going to be using a computer ducting kit that already has mounts for 80mm fans. All that would need to be done to the fans/duct is duct tape to keep it as airtight as possible to provide the best flow of air from your bucket to the "ONA" bucket.

6. Your lights. BOG.com has a 100what bult in their mini one... And ONE 400watt CFL in their big on. I'm not an experienced grower at all.. But I'm guessing you can get away with 2x150Watt CFLS, probably alot less, for this kind of SCROG Grow if placed how mine are.
7. Some sort of drain pan for the bottom bucket unless your using hydro or something similar. I'm just going to be using plain soil for this example to get a general idea of how the bucket works. I have no idea how hydros really work, nor do i have the time or convenience of being able to use one in the forseeable future.
Shall we get started? Lets see.. Started this around 3am.. After writing all that, finding the links, and uploading the pics.. Thanks to a room mate running bit torrent, i've sat around probably a total of 20min opening pages... So now its about 4.40am .. O well time for another soda and another smoke 
Here we go!
Step 1 - First off, The bottom bucket, where your plant will be stored! Whatever size PVC pipe your using, place the pipe against the bucket to trace out a cutting circle. You'll want to cut INSIDE the circle to create a SNUG fit around the PVC, and then use some sort of sealer to keep light and other matter out of your soil, and your soil and nutrients inside.
Once that is cut, Slide your PVC pipe into the bucket. Make sure theres that snug fit. Then attach your 90* elbow to angle the pipe to the top of the bucket. And finally ad your last PVC piece to about where you want your air to come out. Be sure to seal it off before planting so that dirt and nutrients dont make there way into the PVC. Also, dont seal the PVC till your sure about where you want it placed that way you can do measuring and cutting if its too tall.
Make sure you cut drain holes in the bucket so that excess water can drain through. Might want to use another 5gallon bucket or something similar as your drain catch so your plants dont drown in water.
Step 2 - Top bucket. As stated up top, you want the size PVC that corresponds with your fan size to provide optimum exhaust airflow into your vent. Leave room in the bottom of the top bucket so that you can Screw in your fan and Thermal duct and make a good seal around your PVC pipe and your fan/Duct. After tracing your cutting circle for top PVC vent, cut away! Remember, cut inside the circle to create a better seal.
Now that thats done, onto the lights fictures for your buckets. Again using PVC as the light holders(unless using some Pyrex tubing like BOG.com) Measure you lights, and grab some PVC corresponding to the light size. And insert those as well.
As a suggestion for the top bucket. If you go to Barrelofgreen.com and check out what kind of light they use and how they set up the top bucket, you may want to go about doing it that way. Place your light in middle of the bucket instead of the vent. Using the same light ficture technique, and then for the vent. Just place that off to one side of the top of the bucket making sure the hole is above the light level so as not to block any light for the plant.
Step 3 - After setting up your top lid with your exhaust duct, and light fictures, attach your computer fan to the top bucket over the exhaust duct. Make sure you point the fan to blow outward and not into the bucket. CP fans can either push or pull air. Once the fan is connected, attach one side of the vent duct to the fan. You can use duck tape to make a good seal and prevent light from escaping.
Step 4. After making your "ONA" bucket, like our bottom bucket, we'll be taking PVC to make another hole in this bucket. Except this time we'll be starting out with a 90* elbo to allow our "ONA" agent to rest inside the elbow and provide maximum surface for air to be blown across as show in my masterpiece drawing. This seal will have to be extra tight so as not to leak liquid on the floor from the agent. Atop the 90* PVC elbow, attach the computer fan and vent duct. You can use a piece of plywood with a whole cut for the PVC to drill your computer fan into, just enough so that the fan isnt resting on the PVC pipe, unless the fan/duct can be duct taped to the PVC w/o causing any racket other than the fan.
Step 5. Insert lights and make sure your lights arnt getting too hot to melt the PVC(i dont know how hot those lights can get). Again, making seals so light doesnt escape.
Step 6. Place your chicken wire into the bucket around the PVC as your plants will be growing on this chicken wire and will be getting air from the PVC pipe. Dont place it all bunched up in the center, keep it about halfway between the PVC and the edge of the bucket so the plants have room.
Thats about it... It's pretty simple. The credit for the idea, again, goes to Barrelofgreen.com. Head over there for more detailed pictures and instructions.
As for the buckets, try and get black buckets, and then just spray paint the inside of them white to reflect back maximum amount of light. Or you can use any kind of reflective material. Up to you. If your not able to black, you'll want to Either spray paint them black, or just wrap the whole shabang in duct tape to keep light from escaping.
Thats it. Lemme know what you guys think. Any thoughts on how to improve the post or the idea... please feel free to post them up, ill go through and edit the post if more information is posted, or ideas given.
Time to go to bed, its 5.15.. Time for another bowl and my ocean waves soundtrack...
