Stealth DIY Closet Grow Design/Setup

Hello,

Here it is ive been reading up and asking questions for a while now and im nearly at the point where my desired Stealthed DIY grow room is nearly designed to what i want. I have provided many drawings to which i have spent time creating on computer to show you all the ins and outs of the entire room and my plans for what i want to do inside.

Theres several questions that i have to ask in this thread abotu a certain Brand of equipment and ventilation questions, just to get people opinions and decide which method would be best.

GrowRoom:

After spending much time and stress on this design im at the stage where all i have to do is attach the door now , i have taken photos throughout the build of this GrowRoom for when i make a journal of my first grow which provides step by step photos of the contruction.

Its a Pentagon Shaped corner Stealthed Wardrobe unit, a diagram of the measurements and design of this are all on pictures which are linked to this thread below. But let me go into a little more detail about materials and such, i started by building the frame for this grow room using Stud Wall wood posts which is also known as CLH wood i believe. I connected all wood together with using a mixture of Screws, Wooden Dowels and Super Strong Adhesive Glue, i tested the strength of this frame by having my mate who's 15 stonne hang from it and it withheld the weight easy .
I then added 6mm MDF Boards to the 2 back panels which will be facing the wall in the corner, i also added 18mm MDF board to the ceiling and base of the grow room this is so i will have no problem with hanging things from the ceiling as the thickness of wood is very durable, i then added 18mm beech effect contiboard sheets to the front 2 sides and the door. When screwing the contiboard sheets to the frame i then dipped Magnolia screw caps into glue and stuck over the screw to give a nice finishing effect, i then attached the door to the frame using 90degree kitchen cupboard hinges (4 of them). Overall has a very nice effect in my room my rooms laminate is beech wood and rest fo furniture is beech wood, Once i have some spare cash i will be purchasing some laminating edging and attaching these to the top and bottom of the wardrobe to give it the perfect finish along with a nice second hand door mirror (But for now that will do).

Scrog Screen/Mesh:

I will be building this to fit nice and snug inside the grow room, i will be purchasing some rough sawn kiln post roughly 50mmx50mm diameter and i will be atatched these together using glue, dowels and screws again for strength. I havent decided on which i will be using yet but i will either use some strong Garden twine/string for the mesh or i will use some wired mesh which is used for making hutchs as i have plenty of that lying about. I will then attach using the off cuts of my CLH stud posts to the inside walls of the growroom for the screen to rest on level.

Lighting:

I will be using a PowerPlant Aerowing Air Cooled Reflector Kit as the reflector, this consists of AeroWing Air cooled reflector, hanging hooks, adjustable lampholder, 5 metres of cable, IEC connection and the glass panel. £65.00

With this i will be using a PowerPlant 600W MH bulb £25.95 ( i refuse to pay £50+ for the Sunmaster MH Bulb) this will be for vegging and for flower i will be using the 600W SunMaster HPS Bulb - Dual Spectrum £29.99.

For the Ballast ill be using the 600W Digital Lumatek Ballast £140.00 and in last stages of flower ill switch to the super lumens switch

Reflection:

For the reflectionf or walls i will be purchasing 10M of diffusion foil diamond reflection mylar which i will be using for the whole inside along side with some aluminium tape to attach the mylar with. £25.00

Ventilation:

This where im confused and i do not know what to do with ATM im going to go with a Rhino Pro Carbon Filter RVK Extraction Kit, in this it includes
6" Rhino Pro Carbon Filter
6" RVK Systemair L1 RVK Fan
Cable & Plug
Jubilee Clip & Fast Clamp
Aluminium Ducting

Its rated as a 900m3/hr ventilation kit

I will be having a passive intake hole at the bottom of the growroom for fresh air and im confused whether i should do

fan->ducting->Light->Ducting->Carbon Filter using the 2 red holes up top saying A
or
Carbon Filter->Fan-> Ducting->Light using whole B in the green hole up top
or
Carbon Filter->Fan->Ducting and just let it withdraw it all from grow room and pull air through the intake aswell

I will also have a 9-12" oscilating fan at bottom of the growroom blowing the hot air form the canopy and light up towards top of grow room to stop heat building up £21.99

General Grow Equipment:

Edison Light Fittings for addition lighting (CFL's if needed)
ADWA PH & EC digital pen meters ( Budget ones for now )
Digital Humidity/thermo meter to read my temps and humidity
Nutes ( Canna Product Line )
Soil (Canna Proff Soil )
Plant Pots/Trays

Once money is available i will purchase a fan controller thermostat unit to keep control easily of fans speeds and heat.






Ok so first of all what do you think of my detailed grow room including picture, any flaws you can see?

Second of all is the ventilation how should i ventilate my grow room

1) Should i attached ducting to the hood and air cool the hood and do it that way?

or

2) Should i just atatch to the top of the grow room and let it just extract the heat and pull through fresh air that way?


Thanks
Regards

No-one wish to comment or have some input to help me choose which ventilation method is best?

thx

it looks like it might be hard to get into it once you've got everything in there... not actually get IN there, I mean it might be tight to reach back and get to everything you might need to reach. BUT maybe I'm just a person who likes easier access... other than that I think it's a nice space saving design.

as for your ventilation query, I'd go with the second option since if you want it stealth as possible, having a huge gust of air coming out of the side hitting people in the face and blowing your paperwork all around your room would seem pretty conspicuous I think (whereas if the air was blowing out of the top it would at least dissipate a little after hitting the ceiling).

Thanks for the input and yer the reaching the back may cause a little complication but im sure i can work round that somehow with a little thinking ... you dont think 900m3/hr is to much for a 3ftx3ftx6.5ft grow area?

I think i may try and get some acoustic ducting aswell just to keep noise down a little as i dont know how much noise that ventilation kit will make

I tried running a 600w HPS in a 2.5x4x6.5 cab, and with a 4" inline fan (170 cfm) for cooling it was at 90 in two minutes... that is when I went for the 6" (440 cfm). It was not too much, and as long as your temps are good I don't think there is such a thing as too much ventilation (exception: 1200 cfm range hoods that can easily give your home some serious negative pressure and suck CO from your furnace and other stuff into your living space and kill you.)

grantd, I'm no HVAC pro... I just did some reading when designing my own ventilation and got freaked out about how dumb people can be when remodeling a house!

as for noise, I didn't have enough room to vent out directly out above my light with the DIY muffler I made, so I pulled a uturn with the ducting from side of the light to directly above the light connected the muffler and then made a 90 deg turn out the top toward the edge. That might work for you and would keep it quiet coming out. but the actual noise from the fan itself will need to be hushed, is that what you meant about the foam? I put mine in a box with spray foam (you can find that diy on this site, it's a good one) and although it's 60% more quiet now, it's still fairly loud...

one last thing: if you don't vent this air out, your room will be pretty warm (and humid during flower for sure); I definitely had to vent out a window

sorry to ramble, I just know how much advice helped me fix my mistakes before I actually built them. good luck!

Thanks for the advice ive seen and heard about the box with foam spray or rockwool in it sounds like a nice little DIY job ... my room is fairly cold in winter plus i can open windows that dont bother me tbh and i dont mind warmth ill just wear shorts in my room . During the day i can vent outside my bedroom door when no-one is in but in evening it will be vented back to my room, i wouldnt like to directly vent hot air out my window due to it will show up as a hot spot to any feds or nosey bastards outside

So this 900m3/hr will do the job great along with the rhino pro carbon filter and a nice blend of ONA gel products for extra odour control

How much are humidfiers to run?

thx

I love warmth, just not the humidity (moist carpet, bedding, ick). but wait a second, 900 m3/hr... is that 45 cfm? seems a bit tiny for that hot a bulb, can anyone else chime in here??? maybe try it out with a thermometer and be sure your shop has a 7 day return policy!!!

I don't have anything but a carbon filter, they work great all by themselves so save some money on the scents until you know you need them.

humidifiers? you won't need any humidity, you'll need to get rid of it... dehumidifiers are spendy, like $200-300 I think. (bummer about the no venting out the window!)

First things first.

If you plan on kepping this Stealth The RVK150E2L1 is not a stealth FAN. IT kicks out 660m3/h not 900m3/h and around 55dB so wherever you are getting in from are misinformed.

In order to ventilate your grow room and scrub the air you only need the RVK 150A1 which is 480m3/h,

However the trouble you will have is that you will have serious negative pressure inside your grow room which isnt good.

Im about to take you designs and create you a sealed system that will work better than what you are planning so please bare with me.


J

Its a little hard to design around your design.

So here is the low down. IN order to keep your growing area cool enough you will need to create a sealed lighting system. This means that your light pulls air from a cool intake and exhausts away from your grow room. Making it so that none of your smelly grow room air passes through your lighting system

THen you only need a small Fan and Filter combo to keep your air clean.



I have designed a small diagram to show you how i would setup this up. Using a single fan to run the lighting system to make sure you can keep it cool enough using an RVK150E2A1 - 480m3/h sealed so no air from the grow room passes through it. THen having a second fan running the carbon filter and air exchanges using something along the lines of the RVK100E2A1 - 180m3/h

Hope this makes sense.


Personally i wouldnt be using your chosen area but then thats just me.


J

Ok I thought it was very weird as they did some how add 250m3/hr on when adding a carbon filter which made no sense but i thought i was just missing something lol least it will save me more money on carbon filter and fan.

Will i still need the acoustic ducting or is the A1 quiet enough to use just the aluminium ducting?

And thanks you ill wait for your edited design ill look forward to it

thx

jondamon just took a look at your edited design and im a tiny bit confused, it doesnt look like the carbon filter is attached to the hood. Does this mean i will be needed 2 fans? 1 for hood and 1 for scrubber?

Sorry i dont understand, plus do i still keep the passive intake hole?

thx

Edited design is there.

Like i said the A1 is a little quieter but RVK inline fans are not made for stealth operations. Even my RVK125A1 is not stealth.


J

Ok just my bad i understand what your saying now in that design and explanation thank you very much

Why would u not choose to grow in my desired area?

thx

Yes

So your list of kit would be

RVK100A1 - 180m3/h
100mm Carbon filter - 200m3/h
RVK150A1 - 480m3/h


You could use the L1 if you already have it but it is a big ass fan and i use one to cool a 600w that is not stealthed!

You may be able to fan controll it but again you would need to spend around £80 on a variac fan speed controller to keep the humming noise down.


It would go

Carbon filter - ducting - RVK100A1

Sealed lighting system
Cool air intake - ducting - light - ducting - fan

Keeping you lighting system clean of grow room air.

IF you have an RVK150L1 for scrubbing and cooling then your plants are going to be trying to go through the fan, as in the negativa pressure would be that intense that they would try to get sucked up through the fan.


J

When i say stealth i mean like noone next door would hear the fans TBH noone comes in my room causes its my space and the only people that do from time to time know about it so aslong as it wont disturb next door i dont mind it, if it comes to it ill have to buy some acoustic ducting and build some DIY sound boxes for fans

thx

Click to expand...

Too small for all the kit you need to be able to do it properly.


J

Also where are you going to be exhausting too?

Attic?
Room where the grow is located?


J

Ok i fully understand ill do it the way you explained sounds like its a good idea. Thanks alot youve answered my question you ever used a Rhino carbon filter?

im exhausting to the room im growing in i know its not ideal but my room stays very cool plus i dont mind having windows open to keep the room cool aswell. Plus i suppose i coudl exhuast out the room door during day when peopl are out
