looks good in there cruzer 
Thanks Gumball, I think I got it right this time. First they were too big, then too small. These will still be on the small side.
I read those Mantis egg sacks can have anywhere from 50 to several hundred eggs. They will probably eat each other as they get larger until I got one bad ass left. I got two egg cases, They came today. Check it out,
I was thinking about hatching one sack and keeping the other dormant in the fridge for a month if I can.

Wow that way cool. Honestly it doesn't sound any louder than a regular sized swimming pool filter.
Think about using rigid foam to create a plenum around the filter that allows for 3" clearance and a square exhaust vent at the bottom. Again thinking out loud.

oooh can we call him george
Okay that is fucking cool! I've been reading about beneficial bugs and I see ladybugs for sale everywhere. I was thinking of getting some just to see what they would do. I was afraid they would get chopped up in the fans but the few posts I've read said they pass through fans just fine and many people vacuum them back out into a container to save them once there is nothing left. Wierd.Thanks Gumball, I think I got it right this time. First they were too big, then too small. These will still be on the small side.

If I did buy some for fun, is there any way they could screw up my ladies? I'd probably only start with 5 or six and then let the rest loose outside.
Any thoughts?
Cool man, thanks for the suggestion, I didn't know what a plenum was so I looked it up. So basically a box around it open at the bottom right?
George it is.
I tried them a couple times, they just died or got out in a couple days. Same deal in my cab. Didn't even see one after a couple days.
Na, there's is no way they can screw up your ladies. I'd let them all go in there and keep the top soil moist or some kind of water supply for them.
Apologies for the hijack but here's my plenum(s) and I thought it would be relevant to you as well as the others who read your thread.
My issue was cooling and not smell and here's what I had built thinking I was smart...and it worked, just not well enough. Also there were too many points of failure for things to fall apart. Please note this is the top 3' chamber of a 9' tall cabinet so there's 2 more chambers of this ducting below this.
After a rethink and some reading on HVAC systems the idea of a plenum came to me. Seal up the back of the entire cabinet, basically attach a box to the back and cover everything up. Only two points, 1 inflow port for AC and one outflow port for exhaust instead of the 15 individual ones before. Here's the demo:
Here's the frame made from 3/4" PVC. There will be two chambers inside the plenum, the intake chamber which is larger and the exhaust chamber the smaller. I think it's less efficient having the intake larger, but my cabinet intakes are passive and the outflows are active into the exhaust chamber. Make sense? I'm trying to maintain negative pressure throughout.
The frame is attached using zinc pipe clamps around the edges. Then it was a simple matter of encasing the frame in 3/4 rigid foam and aluminum tape.
Here's the only point air leaves the system. I still have it venting back into the garage because it's winter and it smells good!
Later in the summer, I'll filter it and vent it into the house under the staircase which is behind the wall.
Here's the only point air enters the system, through a 10,000BTU upright AC/dehumidifier. The exhaust for the heat exchanger is ducted to the upper outside garage vent. Every time the exhaust blower comes on it puts negative pressure on my entire garage forcing fresh air in through the lower garage vent. Pretty cool huh?
Now you can see the separation panel between the inflow chamber and outflow chamber. All in ports are on the left. All the out ports are ducted to the exhaust side and vented out. I "dug" out the temperature sensor from the portable AC unit and it's mounted at 6' inside the chamber and the AC is set to 70*. My ballasts, pumps and everything are all protected. See why I get pissed at bugs? How do they get through this system when it all buttoned up and filtered. Grrrrrrrrrr.
On the back I cut 3 large panels out to create access to all of the ballasts, pumps, fan controllers, EVERYTHING. Panels come off nice and easy. I was pretty anal at sealing up every crack with tape.
Air comes in passively through vents down by the water tanks flowing around wet towels, keeping the tanks cool, before getting sucked back up toward the plants before venting out the top left and right fan portals. The cool tube also draws and exhausts the same way, just with a shorter path. Notice the plenum principle with my 2" thick rez tops creating a lower and upper chamber?
KISS
Again sorry for the hijack. This was one of my best ideas that actually worked BETTER than I expected or dreamed and it was so simple.
So to answer your question, YES, you would just be creating the exhaust plenum.
I do remember looking at your journal and thinking that was a lot of ducting for that space. Looks much cleaner now.
Ya know, I used those 4x8 Styrofoam panels to section a room for a grow once, Yea, we used 2x2's wedged from floor to ceiling to make a frame then just attached the Styrofoam, cut a hole for the exhaust and bingo a wall! Best part about it was when we took it down you could never tell the walls were there. Worked great. Did that on my first journal here I think it was.

It's also not as deep any more...by at least 8"! It goes closer up against the wall!
Not a lot going on, fed the girls yesterday, 600ppm. Got a cover built for the scrubber, didn't enclose it cause I got new plans and got more ducting to run. I wanna be able to scrub the air from the drying shed, gonna need a couple manual damper's, some 30 feet of ducting and a few odds and ends. There goes another hundred bucks.
I pulled the last of the winter harvest out of the shed and its finishing in a cab. Headband:
The G-13 and silver jack mom are in flower now,
Silver Jack mom:
She was hit the hardest with spider mites before I hit them all with the floramite. Some of that is sawdust from cutting the hole in the wall. Like a dummy I didn't turn the fans off and it went everywhere.

Sorry cruz, but this did make me laugh. We've all been there, and it's always bad when your ground up weed is involved!
How many hours of decent sunlight do you think you're getting at the minute?
I figure the buds haven't formed yet and most of it will blow off the leaf in the next couple months.
Sunlight? I get about 10.6 hours of daylight now, It's been raining today but the last week has been mostly sunny.
I'm running the 600w 12/12 this week.
I found the link to that Daylight calculator, Daylight Explorer
Now I know exactly how much daylight I get each day of the year.
