Firstly I Would Highly Reccomend You Seal Those Cancer causing MDF Sheets
I Have Used The Exact Same Fan Set Up For Keeping A Similar Sized Room Cool Using 2X600's
A RVK 125 Alone Is More Than Adequate For A 400 Watt Lamp, IMO
I Have Just Completed A Growroom Which Is Made From Plywood ( 3/4" ), A Layer Of Chopper Stopper ( Facing Outwards ) A Layer Of 3" Celotex Solid Insulation, Followed By A Layer Of Rubber Horse Matting ( 1") And Finally Finished With Diamond Mylar.
Maybe A Little Over The Top, But I Cannot Hear My PK125 ( Two Speed RVK Fan ) At All.
I Have Decided Not To Use The RVK125 For Intake , As The Sealed Room Makes For A Really Efficient Passive Flow Coming Through.
I'm Using A Single 600 HPS With The New Adjustashade ( Slot In Heat Deflector ) And Max Temps Are 78 Degrees

I Have Retained The Ducting Collars From A Couple Of Homeboxes And Also Cut Out The Logo , Which I Will Stick On My Fort Knox Gro-Box .
Just Before I Add My Second Half Of The Early Haze I Tested Earlier This Year
( 80% Germination This Time Round ) I Am Leaving The Light On For A Week
This Will Kill Any Spider Mites Or Eggs That Have Been In Hibernation, As Long As There Is Nothing For Them To Eat , They Will Starve To Death
I'm Itching To Show My New Pride And Joy , And Will As Soon As I Can Upload Images Of The Construction.
Alongside The Main Flower Room Are Two Closets , Each Housing Fluorescant Lights For Clones/Momma .
I Want To Do A Jorge Cervantes Style Perpetual Style Grow .
The Rubber Mats I Mentioned Come In 4 Foot By 8 Foot Sheets And Are Identical To The Material They Make Fancy Beach Sandals Out Of ; They Are Used On The Sides Of Horse Stalls To Prevent Injury, But Are So Soundproof
Cutting Off Strips To Mount Your Fan In A Anti-Vibration Manner Is Also A Big Plus .
Please Be Aware That MDF Releases More Toxins Than P.V.C, So Encapsulate It ( Don't Use Latex Though !! )
Thompsons Water Seal Works Fine
