Opinions Needed On Ventilation Setup

Ok preparing online basket for when my funds come in soon :D just finished building my 3ftx3ftx6ft beech effect contiboard corner wardrobe unit (Looks very stealth :D will look even better when i get my hands on a second hand door mirror)

I will be using a 600W HPS/MH Lighting setup in this space so im worried about heat issues so ive put together a ventilation kit which im hoping youll give me your opinions on.


Ventilation Kit Contents:




Extractor Fan:

6" Rvk Extractor Fan - 150 mm A1 = 420 m3


The turbines extractors RVK are the best ones of their category. An constructed with the best existing materials of the market. To used for it, motors that work to very few revolutions obtaining the maximum of power, with the minimum noise and electrical consumption. Turbines RVK are the best bet by the quality, since they are practically indestructible, even though work 24 hours to the day without stopping. Turbines RVK with powers exist that go from the 175 m3/h to the 1800 m3/h.




Ducting & Accessories:

Metallic Ducting Duct Tape - 100mm x 45m


We usually use this for fixing ducting onto fans, but it’s also useful for sticking up mylar and other types of sheeting. The industrial strength adhesive is unaffected by heat or moisture so you can be sure it’ll stay put, plus it’s super reflective.

Also used for sealing ducting to fans and carbon filters and accessories


6" Aluminium Bare Ducting - 150mm x 5m



Our Aluminium Ducting features 2 plies of tough aluminium foil/polyester laminate, laminated with flame retardant adhesive and fully encapsulated in a steel wire helix. Will retain its round shape in all applications. Supplied boxed.

Whenever you want to connect ducting either to an extractor fan, Carbon Filter or Silencer use one of our Quick Release Clips. These are the quick tighten worm screw variety and are ideal for strong and secure connections throughout your ducting/extraction system.




Carbon Scubber/Filter:


6" Mountain Air Carbon Filter 150/500 580m3


[SIZE=+1]It's The Carbon
[SIZE=+1][/SIZE]that makes MountainAir™ Filters the Shining Star of indoor air cleaning technology. MountainAir4® is a rare carbon derived from sub-bituminous black coal deposited in a Pre-Cambrian formation some 280 Million years ago. It is from the oldest coal on earth, has an extrememly low ash content, and has a very unique chemistry and mesopore structure not found in other carbons and charcoals.​
MountainAir™ Filters remove 99% of everything under 20 microns from the air in one pass. This includes All organic odors ( Bat Guano,Fertilizers and cigarrette smoke etc.) Someof the uses of these Superior Air Cleaners are: Food Processing, Indoor Growing, Restaurants, Mortuaries, or anywhere odors and air quality are an issue.

So what's so good about the MountainAir Activated Carbon Filter ?

To start with, the resistance to airflow is less than 10% through the filter. Some other carbon filters available have much greater resistance to airflow, which leads to increased noise and increased work for the fans. Secondly, over 99% of particles >5 microns are removed. We have yet to see another filter able to make these two claims. Thirdly, refilling can be done anywhere and requires only an inexpensive rivet tool ($10-$20 at most hardware stores).​
*Indicative CFM: These air flows are indicative of a 37 month filter testing program, at the end of which time the tested filters were still 100% effective. We have also found the Indicative CFM to be the most economical area in which to run the filters (i.e. less electrical usage, fan wear, air noise, etc.).
** Maximum CFM: The filters can handle considerably more air than this rating, however, there are trade off's when running any air handling system at high air pressures. There is a point where it is more economical to go up to the next size filter and this is what the Maximum CFM represents. I.E. you could run a 400 CFM fan on a 6" x 20" filter, however it would be more economical to run a 400 CFM fan on a 8" x 20" filter. Although a larger filter may cost a little more, the savings in electrical usage, air noise, fan wear, etc. is a great trade off. Over the life of the system the additional cost will pay for itself many times over.

Circulating Rotating Fan:

millen-i-Air Air Circulator Rotating fan (9")


A chrome finish air circulator with a steel blade, variable speed motor and a 360 Degree tilt adjustment.

Designed to rest on the floor and circulate air around a large area, ideal for an indoor garden to help avoid air stagnation and ensure even room temperature.

It has 3 speed settings and a cut-out protection to prevent the motor from overheating.​
The Bionaire fan features a high performance variable speed motor with a 360 degree tilt adjustment. Used to generate air movement in a grow room to even out temperature and assist transpiration.​




The Ventilation System comes for about £200 and thats everything in the list with postage and VAT, the thing i like about the carbon scrubber is that it states it can be undone witht he right tools and refilled with fresh carbon which will save money in the long run.


What you think is it to much for a 3ftx3ftx6ft grow area?

thx

I'm running a 400w hps in a 3x3 with 4" vortex fans on intake and exhaust....heat can and will be an issue if you don't have ventilation setup properly. Sounds like you're on your way to a successful venture. Happy growing!

Well see i was planning on doing a nice scrog, so i was thinking under the screen/foliage heat will build up so i was thinking of placing the oscilating fan on the floor facing at a angle upwards to put the hot heat through and up to reach extraction fan. I was thinking of using a passive intake fan and just letting the 6" RVK exhaust fan suck it the freh air through and out again, the exhuast will be placed on the ceiling of cabinet and the carbon scrubber outside the cabinet resting ontop of the cabinet.

I dont know if this would be a ideal setup i need to know what people think of the equipment im looking at and how my plan sounds and give any suggestions or help :D

thx
regards

can you explain why you think this?? its a 3ftx3ftx6ft area its not big at all and many have told me i could get away with a 4" inch and scrubber so i decided to go for a 6" fan and scrubber. Can you provide me with calculations and facts to why i would need a 8" fan for such a small size

thx

Right ok Stonetech cause youve pissed me off with your comment and also the comment you placed on someone elses thread both complete crap oll prove it to you ok

6 feet height x 3 feet width x 3 feet depth = 54 cubic feet thats my grow cabinet ok

Now convert this to meters 54 cubic feet = 1.5291099 Cubic Metre (THIS IS USING A CONVERTER ONLINE SO I HOPE THIS IS CORRECT)

Ok the fan ive choose sucks out 420m3 per hour, so 420m3/60minutes = 7m3 air exhuasted per minute

So if i then divide 7m3 per minute/1.5291099 Cubic Metre my grow area = 4.578 times so this means the current exhuast ive listed will exhuast the air of the whole grow area 4.578 times every minute, now i dont see absolutely nothing wrong with this amount of air floor infact i believe its pretty good unless im told by someone who knows what there talking about. Which is why i posted on here for people with experience to tell me not for you to tell me that i shoudl got with a fan and scrubber that would suck out the air within my grow cabinet 10+ times in a minute

Wow your pretty excitable aye? I currently have a 4" mountain air with a 240cfm fan cooling a veg chamber with only a 250w light. This keeps my temps at about 27-28C. I don't think you would want to go any hotter than that, do you? So I guessed that you would need at least a 400 cfm air filter and fan to keep your temps down. I'm very impressed with your math skills but where in your equation was the heat factor? we're not just talking about air exchange we're talking about cooling. Unless you actually do a test run how will you know? I was merely suggesting to buy more fan/filter than you think you need just so you know your covered. If you go too small your fucked right?

Well whoop d fricking do! Your removing heat (BTUs) no where in you rant do you address actual heat. I can set your room up so it removes 10xs your volume and the heat will increase.

Before you start ragging on people, get educated first.
