Advise needed for next grpw setup please!

Hi everyone,

I am planning my next grow, starting from scratch, i will be growing 4 feminized plants from seed... 2 Barney's farm Vanilla kush and 2 Barney's farm violator kush. I havent bought anything yet apart from seeds, in the planning stage and want to get everything right so help and advise will be extremely grateful. This is what i have come up with:

Darkroom dr100 grow tent
Atami wilma 4 pot drip system
Lightwave T5 4-tube 2 foot grow light for propergation and veg but not sure if enough lumens for veg
600w cooltube HPS light for flower
4 inch rhino carbon filter
TT100 fan 4 inch
ducting
air pump for resevior
Electric Heated Propagator, humidity and air temperature controlled via adjustable ventilators
Canna aqua nutes.

Would really like some advise on ventilation please!
i will have the carbon filter inside the tent, then the fan pushing air over the light and out the exhaust
I am also not sure about the intake.

Sounds like you got it all down what your gonna do

you did not mention a timer though lol

here maybe this can help you out on ventilation

COMPARISON OF CABINET DESIGNS

1. Simple Cab - one chamber, no scrubbers or restrictions to airflow.

CFM = 3.16*Watts/deltaT
where deltaT = 10 *F

Intake Area = 2 x Exhaust Area
Fans - Axial/Computer Fans due to minimal pressure loss

Example: A 400 W HPS in a 3 x 3 x 4 cabinet needs 126 CFM of cooling for a 10*F temp rise above room temperature.
The 36 cuft cabinet is ventilated at over 3 ACpM.

Pro:
Easy to build
Fans - axial

Con:
plants stink up the place
plants are stressed by too much airflow where 5 Minutes between Air Changes is all that is needed.

2. Simple Cab with Scrubber

CFM = 3.16*(Total Watts)/deltaT
where deltaT = 10 *F

Intake Area = 2 x Exhaust Area
Fans - Blower or Inline for high pressure drop across scrubber

Example: A 400 W HPS in a 3 x 3 x 4 cabinet needs 126 CFM of cooling for a 10*F temp rise above room temperature.
The 36 cuft cabinet is ventilated at over 3 ACpM. The hard part is to match an oversized fan/scrubber combination to get the right airflow.

Pros:
single fan design less equipment to purchase

Cons:
Fan operates at 50% or less airflow due to large pressure drop across scrubber
High SP requires a Centrifugal Blower, won't work with Axial fans
Fan/Filter Curves are needed to determine working airflow
Scrubber is many times larger than Ventilation specs to get light cooling airflow
many restrictions in multi chamber designs require special attention to intakes and intrachamber airflow
high airflow for to cool lights creates stress on plants
high airflow through scrubber reduces effectiveness
Centrifugal Blower and Inline Fans are very noisy 60-70 db

i think ur from the uk... im no phycic but anyway.. id get a 6 inch intake . i had 2 many heat issues with 4 inch fans.

good guess, i am from the uk lol.
yeah somone else told me go with 6" and 480m3h fan
