Why not make your life easier and use pots with built-in water catches, or even line the floor with plastic, Tupperware-like containers and then place your pots inside? FWIW, I use 2gal pots from HD - 8 fit perfectly inside a C22 and 10 can be used in conjunction with 9qt trash cans. The pots can yield up to 3.25oz a piece:

Hey fellow millspriders,
I'm nearly done with a c-25 cabinet here's a picture before I put the doors on - I will be putting mylar on the back btw.
I'm getting a 400 watt HPS for lighting and plan to run (6) 2 gallon DWC buckets in here. The ballast will be in the top area along with the electronics. The lamp will have a simple bat wing style reflector with a fan blowing on it.
This is not my first grow - I have been growing in a millspride u-2 counter height cabinet for a while now (7 harvests) under a 150 HPS and a few floro tubes. Here's a picture of that cabinet.
So I was planning on pulling the 134CFM dayton blower I use in the small cabinet and using it in my new c-25 with the 400 watter. It will be pulling through a 118cfm can carbon filter. It has done an excellent job in the old cabinet and keeps temps around 5 degrees above ambient. Ambient is 68 F as the cabinet is in a room with central AC/heat.
So do you think the 134CFM will be enough air movement for a 400watt lamp in the c-25 or should I get a bigger fan asap?
thanks

Most Cab growers with a 400w use a 6" centrifugal. I only use a 4" centrifugal. You could get by with the next bigger dayton than you have but you will need more ventilation. Simon would suggest a darkroom vent. You could also put white backing that came with cab on and put plywood back over it. White is very reflective.
OK then I'll be picking up a 265cfm dayton blower for my exhaust needs. I'm also going to probably add another couple of intakes to the back of the cabinet as well. I'll consider the darkroom louver things - anybody got a good link?
as quick FYI to all y'all out there building cabinets and looking for ventilation... Grainger's has apparently come to their senses and now has a will call option - that's right just give them a call and an item number and a name and they'll let you come pick up what you need cash and carry - They carry the full assortment of dayton blowers at much less than any hydro store - for example my 134cfm was $39 from them, a 176 cfm is $44.95, and the 265cfm fan is $68.50 - at a hydro store you would pay around $150 for a 265cfm...
So just look up what you want on their web site and give them a call with the product number, when they ask if you have an account just say, "no, I just wanted to come in and pick it up" and they'll ask for a name (fake of course) and if you'll how you'll be paying (cash of course).
For those interested in a quieter inline fantech fan I recommend calling them at 1-866-710-4769 and they will be more than happy to give you the name and number of a local retailer. Again the savings is substantial, a FR150 (250CFM) model will run you over $200 at a hydro store, but my local electrical supply place sells them for $147.

Here's a link to froogle with the darkroom louvers:
http://froogle.google.com/froogle?q=darkroom+louver&hl=en&btnG=Search+Froogle
They look great and work well to block light but they are costly.
Good info about the Grainger pickup. Never knew you could do that.

~$25 is costly? See what PVC costs that covers the same surface area and then double that to achiever 2x90* angles needed for a light trap. Add to that the ease of installation and put a value of the lack of logistical constraints. I could never understand the desire to go cheap when the final product is so valuable. It's not like we're growing potatoes.

They are actually cheaper than I thought and the smaller louvers (round ones) are pretty cheap although you would need at least a few. For the next cab I build (hopefully soon, need $) I will definitely use the louvers. Still the larger square ones are pretty costly. For 2 of them you'd be out $50. I could get an 1/8 for that price or build something for less to block the light.
Good to see you on icmag simon, I remember you back from OG.

well alrighty folks - I've got 4 of the 2" pvc elbow intakes installed in the cabinet floor already. I just ordered a 3 pack of those 4" diameter darkroom louvers as well and will add them to the back wall of the cabinet as needed to increase airflow.
I also just picked up a 265cfm dayton blower which I plan to use as my exhaust fan. I will not be cool tubing the reflector but plan to have a small dedicated fan blowing across the bulb when lights are on.
Now all I need is for my 400 to show up.

This place has a better deal on louvers... not sure about the shipping.

The smaller (Midget Louvers) aren't bad, but (relatively) not as effective as the 8x8s. I have 4 of the Midgets and 2 of the 8x8 in each of my C22s.
You'd most likely need two in a C13 size box. There's no doubt you could build something for less and there's no reason why you shouldn't, if you're so inclined. I'd just encourage you to think about placement very carefully. As illustrated in the cab posted above, PVC (for example) has to either be positioned under the cab or it has to stick-out inside. Both intrude on our aggregate limiting factor - space. Both limit pot placement that can be easily translated into a dollar amount.
Let me use myself as an example. I pull ~14oz dry/cured bud out of each of my boxes, which translates into ~2.3oz per square foot. If I loose a half a foot of space, that's ~1.7oz of dry product at harvest at ~$300/oz. This is assuming the loss would be linear, and I'm betting that's an optimistic proposition. So by trying to save on a one-time expense of a few dollars, I'd loose a whole lot more at each and every harvest for the life of the box.
Thank you. I appreciate the kind sentiments.
hey simon,
what do you think about my plan to use the (4) 2" OD PVC elbows that I already installed in the floor - with foresight to the placement of my (6) DWC buckets - plus a couple of the 4" round darkroom louvers?
I was thinking that I would put either 2 or three of them in the back wall but I suppose I could put one in the back wall and one each on the sides if you think this would be better?
the ventilation fan is a 265cfm dayton and the light will be a 400 watt hps with both the fan and the ballast in the space above the grow area.
will this work in your opinion?
thanks in advance,
suga

Simon- Would 3 8x8 louvers be overkill for a c13? Im asking because I still have a lot of suction on my doors (to much). I know you do those lil equations with the space that will tell you the exact answer Im looking for. I currently have 2 (what you recommended me at og). My ladyz butt up right against the louvers when I pack the shit out of my room (reduce intake). I jus think that a 3rd one right above the two might help out a lil with a powerdy mildew prob I have.
room packed with ladyz louvers covered
I put my louvers to low so I reccomend to put them a lil higher than mine.

Throw one on the other side if you do install one mysta...
I use a speed controller to turn my 4" vortex all the way down. With two louvers installed it still suctions the door shut pretty well.
