Custom Grow Cab Suggestions

Hey everyone, apartment dweller here looking to move from a tent to a DIY cabinet. I have a rough idea on requirements, dimensions, etc. Just looking for a few answers and your suggestions and opinions.

Dimensions: Again, I'm an apartment dweller who unfortunately lives on the third floor with a narrow staircase. The maximum I could go would probably be 4 ft wide x 2 deep x 4.5 high.

Requirements: Two separate chambers; main one for flowering and another much smaller one for clones. Proper ventilation and air scrubbing. I have all of the hardware already for this. Ideally it would have the electrical components plugged in to a high wattage powerstrip mounted in its own compartment, maybe accessible from the side. It has to be 100% light tight, which won't be difficult. If I can think of anything else I'll edit them in.

I'll be running a 600 watt hps / mh in a cool tube vented with a 190cfm fan. I've got a ~300cfm carbon filter that my 100cfm duct fan should be able to pull enough air through the whole cab from the intake at the base of the cab. I was thinking of running a t5 setup for clones, I'm open to suggestions on this as long as it's not cfls, I've had my run with them and am over them for my needs currently.

I'm open to any suggestions on design opinions. I really have no requirements except that there be no access panels/doors on the rear. I'll have to sketch something up later but essentially I was thinking that the main chamber would go on the bottom, the above would be the cloning chamber, and then possibly an area above to house the fans, ducting, excess wires, etc. I think that my 100cfm fan should be strong to draw air from the bottom through different compartments (Light tight vents between compartments will be necessary) and vented through my filter, correct? I'll be fighting heat with my 190cfm fan that will have its own ducting; in through the fan then cool tube for positive pressure, which means the intake will have to be mounted in an odd spot, like I said, I'm open to suggestions. Though as I mentioned I would prefer to have an access panel on the side to house wiring. The goal is to make it appear to be a simple cabinet that has one cord coming from it.

I'm not too terribly knowledgeable on cabinetry or woodworking, but my grandfather - veteran grower of like 30 years - has his own workshop and will be providing help along the way. We're pretty sure we're going with a mix of Cedar and Pine.

So there's my idea. Pick it apart, give me suggestions, show me yours or just drop some advice. I'll keep posting as I go along.
 
My #1 suggestion...

It is much easier to veg and clone on top of a shoe box in your closet than it is to try and make a two chamber box work.

That's just me. I'm lazy. I like my life simple. I don't want to deal with light leaks, shared ventilation, triple exhausts (one for light in veg room, one for light in grow room + one for the grow room itself)...

I love the idea of having an all-in-one tent, I really do. I just don't ever see myself taking the time to rig it up. I'm lucky I got off my half-crippled ass and built the tent I have...

I'll actually only have the extra chamber for clones as my ballast runs both hps and mh. So I'll veg and flower in th3 same chamber. I'm not concerned with having a perpetual harvest or even vegging for very long, 30 days max. I would like the clones to have their own area because my gf wants more space in our apartment as well as me wanting it to be as stealth as possible, for obvious reasons of course.

In my experience it is difficult to stop all light leak. I still get a glow out of my light trap for air intake, and unfortunately it restricts air flow a bit.

4.5ft tall minus container size, minus light height, minus minimum distance between light and plants, doesn't leave much room. Serious lst or scrogging will be needed for minimum plant numbers. Otherwise sea of green with no veg time.

I lst like crazy and usually run 12 / 12 from seed or a very, very short veg. In my tent I only use about two feet of vertical space for my plants.
As for the light leaks I think I may have a way to make sure it's 100% tight. But I may have to buy an additional fan

I've been thinking pretty hard about the height limitations that you mentioned and I feel that in the long run I am going to want more height, especially with a 600 watt light.
I think removing the secondary chamber for clones might be the best route. If anything, I can build a second smaller cabinet that can be stored away when not in use.

You can literally clone or veg anywhere, especially if you are going 24/0 and it doesn't matter if it's lightproof. Granted, I suggest a dark period for clones, but in a pinch, 24/0 works just fine.

I have literally stuck a light socket adapter into the plug in my wall, and shoved my clone box under the wall outlet with a CFL for 2 weeks before. I know that's not an option for most people, just saying, it can be done anywhere.

Under a sink, in a closet, under a computer desk. Literally anywhere that stays private and you don't mind having light. I personally clone in my 3rd bedroom closet that has nothing but Christmas ornaments in it anyways...
