That's a lot of light for such a small space. Use lots of reflectivity as it's going to be hard to get your light to throw that shape of a footprint.
If they are growing like they should, 60 days veg won't be necessary at all. I could fill a screen that size with 2 plants in 40 days from clone, at the absolute most.
I'm all about "ghetto" setups, Goodluck bro!

Manual light mover, nice!
No though, I can't see any pics. Make sure any pics/album you upped isn't on private.

Welcome GhettoInc ,
I am afraid for heat issues with 1k in this closet , hope you have low temps outside so you can cool it down , watch it closely , wish you the best

90F may be problematic with DWC. You can give it a go if you want, use LOTS of air in the solution. I'd probably run it with a conditioner like DM zone as well.
At first sight of root issues, i'd transplant to coco or soil.

If you have low outside temp you can make it , but....
I think that i have some homework for you bellow it is a very helpfull link
that it will solve all of your problems before you face them .
Veltilation 101

or you can try this
Q=V*P*C*dt
Q=radiation in KW
V=volume of air in the room
P=density of air (average 1,2kg/m^3)
C=heat that the air can remove(average 1,02kj/kgK)
dT=temparature difference ambient(where you draw air) and room temparature
example
400w hps = 0,4KW
ventilation 240 m^3/hour=0,067m^3 sec
ambient temp=21 celsius
Q = V * P * C * dT
=>dT=Q/(V*P*C)
=>dT=0.4/(0.067 * 1.2 * 1.02)
=>dT=4.87
conclusion
room temp = 21C + 4.87=25.87C
You can feed me with your numbers in my sig's grow log
to make the conversions for you !

Thank you erwing, unfortunately math is not my strong side
whats going to be the optimum temp for dwc? I can get the temps in the room its connected to its in down to 30 degrees easy if i want to. Thats why im doin it in there this time of year.
All i gotta do is crack a couple windows on the light cycle and its gonna get chilly in there.. Im gonna have a 6"450 vortex and 2 regular fans. Do you think RDWC would be little bit better? I was just doing it this way cause im gonna have 2 or 3 separate strains. And want to get them dialed in

as for solution temp inside buckets...
65-68F is ideal in DWC for Dissolved Oxygen and pathogen control. You'll see an increase in speed of growth as solution temperature rises, but with an increased risk of pathogens. Using DutchMaster Zone, I don't usually get concerned unless the temp goes over 78F, but I try and keep it under 75F.
RDWC allows you to add a chiller, but from the sound of it you'll be able to control temps without one. Maintaining separate DWC reservoirs is a bit of a pain, but worth the effort.
as for room temps 70-78F is a good range to aim for.

Thanks bendo. I think im gonna get a couple inline fans pullin air into the room and have em set on e thermo to come on at 70 I think that will work. Im gonna add the dutch master zone to. I think im gonna put 4 buckets in the room instead of 2 then just scrog the whole thing. I wonder if i could separate the bottom of the containers from the top part of the room, put my passive intakes on the top and have the 2 inline fans just cooling the buckts. Would that optimize growth if i could keep the buckets at 65-70 and the tops at 75-80?(Sorry im a little bit fresh on doing it hydro, almost all of my prior experience was with soil im trying to make a conversion over here for bigger yields and less mess.)If I made a setup like this and just had the pump sitting in the main res and all the buckets connected like that is this going to help things get flowing. and if i do that do i put airstones in all the buckets and the res. How big of pump would i need for 3 5 gallons would a basic rdwc system like this work a little better than standalone?

Your talking about blowing cold air at the buckets right? Ambient temp air won't cool any more than ambient temp. Never tried to cool like this but it sounds feasible.
People usually insulate the buckets and fill with colder water if they aren't using a chiller. Insulating would be counterproductive though if your going cool them with cold air. Some people use frozen soda bottles as well, which is a PITA. A chiller is serious coin/e- so probably impractical for a setup this size.
Having that extra rez will help keep the temps lower longer, as it will take more energy to heat up more water.
rdwc setups feature top feedlines and bigger drainlines on the bottom with airstones in each bucket. I'd take a look at some of the RDWC systems on this site. I take it you've seen Blazeoneup's tutorial, it's pretty much essential reading if your going rdwc. PureKnowledge's rdwc setups will also give you an idea of what these systems can do.
nothing wrong with standalone dwc though, especially if your only doing 2-3 buckets.
