Advice on equipment set up needed please

[alfie moon]

Hi there,
I am back for my second attempt at a decent grow but for the life of me cannot work out the best way to use X4 air cooled lights,

I got a grow tent 2.4 metres long X 2 metres wide by 2 metres up and down, I have X2 Big wilma pot 8's in there and 1 big 4. So total of 20,

Got a 8" carbon fan which i think maybe a little big(any advice appreciated as the shop sent this as not have a 6" in stock)

Also got the X4 air cooled lights, what i need to work out is the best way to get the air going through these, I.e cut 2 holes at one end of tent then another 2 at other then suck straight through? I ask as the lights are going to need to be moved up as time goes on and with the acoustic ducting its very difficult and takes up a lot of room in the tent,

Also I would like to vent into the room with the window open but would it be better to drill through chimney in loft and vent out through there? It is summer in uk right now, not a little suspicious heat there?
I was doing fine everything was moving along nicly and the grow shop cocked up my order, parts missing, sent me a supposedly silent fan that sounded like a cowboy in a brothel, took it back,
since i just cannot get my head round the best way to go here, i also thinking of just doing the whole room now as i have made a hole in the ceiling but then changed my mind!

Could really do with some advice, i will be growing with clay pebbles 18L pots hydro wilmas. I got 4 chronic that i need to clone before i start and 4 super skunk all from nirvanas seed store.

Set was looking good, now i cannot make up my mind way to go, Opps almost forgot i brought 4 300w led lights also, i am going to try to get them in tent also but not sure if i can as roof bars are a bit strained with the lights and acoustic ducting it pretty heavy/chunky stuff.
I thinking the fan i brought today may also be to big its a TD800 - 200mm / 880 m3/hr, its is very very large but supposed to be silent as you can currently get and i need that for sure,
Any advice on the set up would be most welcome,
List what i have tio work with

2.4X2X2 metre tent,

X4 5inch air cooled 600w hoods on digital dimmable ballasts (super lumens) plus 5inch acoustic ducting

Rhino 8inch carbon filter, with acoustic ducting also, (bit to big but maybe needed that size?) Went on the advice of store as they had no 6" in stock

S&P TD800 - 200mm / 880 m3/hr silent fan

Rvk 125mm A1 5" 250 m3/h fan for sucking from the lights

Pretty much covers the main stuff, i got my seedlings under a 150W light x-stream propagator,

Sorry for the long winded post, i been reading stuff here for days but just get lost reading other stuff! could really do with some advice.
thanks

wow,

you need to step down your setup man.. your are one of those growers who jump the gun.. in this game is slow and steady. you need 1 600 and that's it for your first grow. you need to concentrate on your plants and what there doing and how your feeding / watering affects them..

also you have way to many lights... way to many for that tent. I'm in US measurement but I think that tent will hold 2 600's nice.

are you doing soil ( organic or chem ) or coco? and what nutes so we know

Not that different from my setup in square meters, mine is home made. But area is the same so here is what I use.

7 x 400 watt. Every light has an 8" duct fan blowing straight through the ceiling to an upstairs vent room. 3 additional 6" fans stir the air inside. The vent room has a 24" fan blowing directly through a wall to outside. The passive inlet draws screened outside air in from the other side of the budding tent. Air is drawn through the tent, through the lights, and out of the house. I don't have UK conversion but 6" fans are 380 CFM, 8" fans are 500 CFM, 24" fan is 6500 CFM.

If the outside temperature (inlet air) goes over 22 degrees C the venting cannot keep up. I did not see a refrigeration unit in the list of supplies. I live close to the arctic circle, it breaks 22 about 4 maybe 5 times a year, not so much a problem.

4 x 600 + 4 x 300 is close to my 7 x 400 in heat per given area so expect up to 4 degrees C above ambient without a cooling unit with the fans.

I agree 2 600 is plenty for that. IMO you would run into problems with heat maybe light bleaching if you use 4.
