What Wattage light would you recommend for this grow space?

Height - 6' 8"
Width - 3' 3"

I was thinking of a dual spectrum 600w or 400w HPS but what would RIU recommend?
I currently have 105w & 45w 6400k + 125w 2700k CFL's for Side-lighting.

Also think im going for a 5" inline fan for extraction rated at 355 m3/h (209 CFM) also comes with a carbon filter.

i know nothing about uk supplies but i use a 440 cfm carbon filter and fan for a 400w and it works i can keep temps at 76 when the 10k btu ac is on. i got mine in the closet in my room. so i turn the ac on anyways and it keeps it 76 in there and like 70 out in the room. i use a 400w

i also wanna add in that keep the fan and filter running 24/7 and on a speed controller if you want. i got a speed controller and havent even used it.. its hooked up but i always run my fan at max 24/7 if i dont, i can easily smell inside my house which is a no no.

Okay, thanks for your input :)
I have just converted the 355 m3/h and its about 209 CFM do you think this is suitable for my space?

it depends on how many bends and stuff are in your ducting. bends decrease cfm. 200 cfm equal to a 4 inch inline fan here in the us. i lived in a tropical climate when i had it and it wouldnt work. now i moved up north (cooler of course) and i bought the 6 inch and it works perfect. and keep in mind i use a 400w. if you get a 600w (which i wish i had) you prolly should get a 400+cfm but either a 400w or 600w would work. how many grows are under your belt? im almost done with my second. i first started with cfls... then bought a 150w hps.. sold that and got the 400w and im gonna keep that for 3-5 more grows then upgrade again

I have 2 grows under my belt, not the best but still they was successful,I also started with CFL's. I have a basic understanding.
Think ill go for the 400w HPS, and i'm planning on using as little bends/ducting as possible, vent from top of closet straight into room with an intake at the bottom of the closet, negative pressure coming into play ofcourse.

i would go with the 400w until you figure out how the heat is going to be. i also would choose another fan and filter. i paid 80 usd for my fan and 80 usd for my filter and those are cheap and gets the job done. idk about negative pressure lol but i got my fan on top of my filter sucking air in through the filter and pushing it though my light into the roof of the cloest, or the attic floor i got the filter on a flower pot with a bar stool seat on top lol to help with vibration and i cant hear it anywhere

Okay think I will do, And basically to achieve negative pressure, you must be sucking more air out than you are putting in to reduce odour leak etc
