Check my plans before I build, 600hps 3ftx13ftx8ft dwc vertical?

Just looking for some more experienced opinions before I finish setting things up.

Veg room will be fluoroscents in about 3x4 room
Flower will be a 600hps with cooltube in about 3x4 room
DWC hydro
Space is 3ft wide x 13ft long x 8ft high
Space is in a basement which helps to keep it cool.

5gal buckets for flower, probably 3gal for veg. Each system will be recirculating with a reservoir and top up setup.

Will my exhaust work as i have it in the picture? I plan to intake from the flower room, then from there to veg room, to scrubber and out.

Intake-->flower room-->cooltube-->duct-->vegroom-->scrubber-->fan-->duct

Is this too much with a 424cfm fan? Temps range from 30s in winter to 90's in summer. Usually in the 70's in summer though. I can draw air from outside, under the house, or from inside the house.
I plan to have the fan on all the time at a reduced speed and a temperature control to turn it on to full when needed.
Will I be drawing to hot/humid air into my veg room from the flower room? Should i go veg-->flower instead? I figured that may add humidity to my flower room.

I am also looking at doing my flower room as a vertical scrog.

Any help and opinions are appreciated.

I don't understand why you'd be running the duct along the ground with severe turns like that, but I don't know your space either.

How many watts of fluoros you going to use in veg?

I will try to avoid too many sharp bends, but some odd routing may be necessary. Trying to bring air in low and exhaust higher.

I'm still figuring out how many watts of fluoros. Probably use cfls.

If you're bringing in the 600w exhaust at the bottom it's not going to be good. You should get a 400w MH and run it inline with the 600. 2 cooltubes and the 424...... you'll be sitting pretty.

Might do a mh later but want to try out the fluros for now. I think i may flip the rooms around and draw go intake->veg room->flower room so the last thing exhausted is the cooltube. Will this give me too much humidity from the vegging plants going into my flower room though? I'm trying to avoid getting a fan for each room and another for the light if i can and just use the one fan.

If you cheap out now, you're going to have a bunch of unused equipment just laying around later. It's a waste of time and money for you to not do it proper from the start.

Fluoros create a lot of heat for the little usable light they kick out. You get 400 watts in a 3' x 4' enclosed area especially with another 600 watts coming through and you're plants are going to bake. I'm just warning you bro.

Looks like I've got a few ways to fix my venting:

#1 Flip it around and pull from my veg into my flower and out (increases flower room temp and humidity)

#2 Run a Y splitter off my fan with one side going to veg and one to flower with the carbon filter on the PUSH side of the fan (cheap and easy, if my fan can handle it) pic included of this idea

#3 Run a Y splitter and get another carbon filter so both rooms have their own (costs more)

opinions or other ideas? thanks.

I have 2 rooms each 3x4x7 so each are 84 cubic ft. Total of 168 cubic ft.

The fan/filter i have is the 6" growbright from htgsupply rated at 424cfm.

Ignoring loss due to backpressure thats an air change every 2 1/2 mins. So I think the fan can handle some odd ductwork, splits, and pushing through a carbon filter if needed, right?
