I will be moving into a townhome in a month or so...and there is a perfect little closet that I plan I turning into a grow room.

Currently I have a 250HPS and a 400MH Lights. I know that HPS is better for flowering and MH better for Veg but i'm thinking that it would be in my best intrest to veg with the 250hps and flower with the 400MH just for the simple fact its more light. Would that be the best idea? Or just veg with MH and flower under a weaker HPS?

Anyways on to the the grow room set up.

The closet is 1.5ft x 5ft x 8ft. I'm planning on dividing the closet down the middle to create two even sections. Attached is a weak ass mspaint drawing that i threw together so you can see the way i was wanting to set it up. I have a stealth cabinet conversion that i was originally going to grow everything in but with the closet i will use the cabinet for my clones and toss a couple 2ft fluros in there to get the clones going.

The fan i'm going to be using is a 740 cfm fan is that going to be enough to properly ventilate both sides of the closet?

The intake ports are messed up in the drawing they will be right next to each other and they will be drawing air from the other side of the wall(The right side of the closet wall is above the stairs. I was planning on using 2in diam pvc pipe( 90 degree elbow mounted directly to the wall then another 3in long piece running alont the inside wall of the closet to help eliminate light escaping or entering through the intake ports) On the outside of the wall i will be mounting an AC vent with the little slit type vents all pointing upward to cover the intake ports so that you cant see them walking up the stairs.

Also is it ok to have the exhaust dump through the odorsok and into the utility room since that room will be sealed off from the veg/flower chambers?
Does it matter if you set up your carbon filter on the intake side of the ventilation system or the exhaust side? Does it work better with air being pushed or pulled through it?

If you look @ the diagram i attached you will see that in the flowering chamber i will have the fan hooked to one side of the cool tube drawing air from the chamber through the cool tube and using passive intakes...is this going to be good enough to ventilate the chamber?

I picked up a Soil PH Meter from Lowes...http://www.lowes.com/lowes/lkn?actio...isture%20Meter....are these fairly accurate or would i be better off using the actual soil test kits with the pills that you disolve in water?

Is the way I have things set up in the picture going to work? Any ideas on how i could improve the design?

It seems like overkill with the lighting in that small of an area. Have you thought about making it one room and using the 250 in conjunction with the 400? It would give you a full spectrum throughout the grow.

The fan seems like it would be enough but your lights are going to put out a lot of heat.

HeyBP,
Thats not a Soil PH Meter. Thats a moisture meter.

Haha yeah i linked the wrong one...http://www.lowes.com/lowes/lkn?actio...230&lpage=none

your going to have problems with trying to keep the humidity up , you might have to get a speed controler for the exhaust fan ,, and yes it makes a diffrence with the filter ,,have it sucking through the filter though the fan then cooltube and out ,, you should have foam rap around the filter so moisture dont get the carbin wet and will make it last longer ,, got any problems let me know , i just set up 3 grow closets snd was faced with allmost every problem lol

a MH is better for veg but only in the long run , if your closet aint that big i would just stick to the HPS the whole grow.
