 Grow room from scratch 
#750103 - 09/27/14 06:22 PM (10 years, 6 months ago) |

Hey everyone, as the title suggests, I'd like to set up a grow space.
The available space is 6'W x 5'L x 7'H. Note that the floor wall and cieling of this space is plywood. These is a already a mesh filter of some sorts I'm guessing for air exchange. *note that this space is a small trailer next to my house
I am virtually clueless when it comes to everything that goes into a successfully incognito grow room.
What I'd like to do:
-Hydroponics(Thinking about this ebb and flow https://www.icmag.com/ic/showthread.php?t=70262)(I'm going to install a regular overflow valve instead of doing his method of draining the flood table.)
-Have space for a decent amount of clones(5-10) Have space for a few mothers (1-4) and a decent sized flowering space.
-Use no more than ~600 or so watts for the entire space.
Okay so, those are goals I want to achieve with this space. Now making it happen is the hard part.
I have a ton of questions and will ask them all. Answer any of them that you can and personal tips are always a big help as well.
1. Should I use plywood, insulation board, a tent of some sorts or what when building a divider between the 3 areas (veg/clone/flower)?
2. What am I going to have to do to make this area 100% smell proof? (*Note that mesh screen thing that provides FAE)
3. Living in an area with high humidity, will I have to add a dehumidifier?
4. Me living in a hot area, and the trailer being a dark color, will I have to buy a water chiller for my res or add AC to do space?
Those are all of the questions I have for right now. Now here is a list I've been compiling of everything I'm going to need to buy.
(For the ebb and flow table itself):
8 1/2 adapters
8 elbow with side outlet
130-170 gph sub. pump
Black 1/2 ID Tubing
3 1/2 barbs
4 4ft 1/2 pvc tubing
1 tub from concrete section of lowes (the smaller one)
super glue
Duct tape
10 Gallon rubber maid res.
For the room:
Mylar
Material to divide up the space into 3.
Rockwool
Hydroton
4" net pots
Lights(thinking of doing a 150W mh for the mothers, 400w hps flower and 50w t5 for clones)
Hygrometer
Thermometer
Ventilation material(idk what to do for this)
Now everyone, thank you very much for the input. Everything and anything is appreciated. Anything you have to add, suggest or recommend is appreciated. I'm very new at this and willing to learn so please, by all means, bombard me with as much information as possible.

Wow, amazing design. So simple yet so complex at the same time.
After everything is built, what are plant sites filled with? I think that you use lavarock, but would hydroton be possible?Since it's like half a 2 liter worth of root space, I imagine this setup is designed for a small plant SoG?
Awesome setup though and I'd definitely use this for my flowering space. I guess SoG it is 
Now do you have any good setups like this for a mother room and a cloning space?
What goes into setting up the lights? (100W mh for mothers, 50W t5 for clones, 400w hps for flower)
Is the amount of light I'm thinking of using even enough for supporting the amount of plants I want?
How am I going to cool all of these lights?
Will I have to introduce AC to the environment?
What I'm thinking of doing for ventilation is installing a vortex fan around that mesh screen thing for air intake into the trailer, setting a carbon filter in the middle of the grow room and installing a vortex fan on top of it pulling air into the carbon filter. With this plan will I need a space for exhaust?
Sorry the amount of questions. I just want to get this show on the road.

Also for that design, should I spray paint the bottles black or something so I won't get algae growth in the root zone?
How large is that res at the bottom?

Here are some pictures of the space I have. Exactly 69"W x 72"L x 73"H
For the clone area:
Thinking of basically doing an SGFC with the cuttings inside in rockwool with a 54W t5. Could I support 11 clones with 54 watts?

Well when buying lights, I know I need a ballast, a hood and a bulb, is there anything else I need?
I'm thinking of going with these ballasts and bulbs and increasing my mh wattage to 175.
MH Ballast: https://www.1000bulbs.com/product/89417/PLUSRITE-7210.html
MH Bulb: https://www.1000bulbs.com/product/5040/MH-01751P.html
Hps Bulb: https://www.1000bulbs.com/product/4982/LU0400-0002.html
HPS ballast: https://www.1000bulbs.com/product/71058/PLUSRITE-7276.html
And any recommendations on what brand of hood should I use?
I'm going to need to be taking 11 cuttings every 8-10 weeks, preferably of like 3 or 4 different strains.
How with holes in the bottom of the trailer would it remain smell proof? Also, what kind of fan do you use to draw fresh, cool air through? I'm looking at vortex fans and they're like $100+ which is a bit ridiculous.
About ventilation: If I'm getting this right, you're saying that I should use one of those FAE sites on the trailer, pull in air through that(it already has a screen for bugs), and duct that air up to the lights to the HPS to cool it off. Then I'm going to duct it through the wall up to the MH and through the wall diving the trailer into 2(not the same wall dividing the veg and flower room) into the remaining space I have not used for any growing. I will just set a carbon filter and an inline fan in this space so that any air that passively drifts out of the other built in FAE site won't smell.
About actual construction: I'm going to set the flowering side up next to one of the ventilation holes already in the trailer so I can draw the air directly to the hps which I assume will be the hottest. Then I will build 2 walls, enclosing this space(one wall parallel to the already existing trailer wall that has the FAE site that will divide flower and veg room. And another wall perpendicular to the divider wall and already existing wall all the way across to the other side of the trailer that will enclose both rooms to the other side of the trailer that I use for storage). On the other side of the divider wall, goes my 175 watt MH and the mothers. Can I stick my SGFC clone box right in with the moms(I'll be using an 85watt CFL 5000k for clones) and keep them on the same light schedule?
Mag I really want to thank you for all this information. This project could not be possible without you

Will I have to use AC for the ballasts? Or can I stick a desk fan next to each of them to keep the heat at bay?
Buying some of the shit today and ordering a lot of it this week. I cannot wait for this to get going.

Hell yeah! Awesome news
So any is there any particular set up you'd recommend for mothers? Maybe handwatering coir?  It will have to sustain 11 clones every 8 or so weeks.

1. What fans should I use instead of the computer fans?
2. To the right of the 150w bulb I drew in a computer fan pulling air out(the edge of the page is the wall of the trailer). Like you said, I can't use a computer fan. So would a normal fan up there pulling air out not be enough exhaust?
3. For the ballasts, should I just invest in some digital ballasts and be able to run them inside the room? Or could I build a buffer room between the empty space in the trailer and the front of the grow space and put the ballasts in there?
4. And I'll just switch up the whole thing and flip flop the veg/flower space so the 150w heat will be blowing onto the 400w

1. Would exhausting into the buffer room be possible? What I mean is that I'm going to intake air from outside, vent it through the veg and flower spaces and into the buffer room. I guess I'll install a hole in the wall of the buffer room(with a screen) exposing it to the open area of the rest of the trailer. And then when in this space could passively drift out the 2nd FAE site my trailer has? Doing this, I'd just put the carbon filter + inline fan inside the buffer room. So the smelly, humid air I vent out from the grow space will go through the carbon filter in this room and then can just passively drift out.
2. Sound advice
3. How about this for a fan?
http://www.amazon.com/VenTech-DF6-Duct-Fan-240/dp/B005KMTYFK/ref=sr_1_15?ie=UTF8&qid=1412110830&sr=8-15&keywords=centrifugal+fan
4. How many of those fans will I need to pull air in from outside and push it into the buffer room with that plan I described earlier?

I'm looking for fans like that on homedepot.com but not seeing any. Also the cheapest centrifugal(squirrel cage) fan they have is over $100+
Do you think I'll be able to get by with the inline in that link?
I'm thinking I should just replace the circled areas in this pic and put one of the inlines I linked in each of these locations. Pretend that the right edge of the paper is the wall in between the flower and buffer room(in reality the buffer room will be in front of the flower room not beside it). I will pull in air with the first fan and continue pulling it through with the second and also pushing it into the buffer room with the second where my carbon filter will take care of all of the smell. Now this non-smelly air can passively drift out through the screened hole in the wall of the buffer room into the empty space and out of the 2nd FAE site.
Thoughts or concerns?
EDIT: I'll try to draw up another updated draft of the diagram tomorrow.

So awesome to hear that!
Picked up the PVC for the flowering room today.
This project is coming along nicely 
Cannot wait for this thing to be up an rolling.
You have seriously been a huge help with this whole thing.
Having an expert grower answer any question I have is an awesome resource 
Have a great night magash I'll post the updated diagram tomorrow.

Hey Magash, I drew up what I think will be the final draft of the space.
View of flower and veg room facing north:
View of the rest of the exhaust plan facing east:
It looks kind of weird and hard to understand when drawn so I'll explain it to you.
I'm pulling in air through the eastern wall into the veg room and then into the flower room. I'll only have one fan in the air ducts and it will be placed in between both lights so it can pull air onto the first light and push light onto the second light. (My only concern with this is if the fan isn't strong enough to pull in air from that far away.)
The air, now having been pushed into the flower room, will be exhausted by another fan that is mounted to the southern wall that is pulling air out of the flower room and pushing it into the buffer room. I didn't duct the second fan to the light because I want it to pull air through the room to give the flowering plants some FAE before it's sucked into the buffer room.
Then as you can see, the ballasts will get some air from the exhaust and then it will be sucked up by the carbon filter. I'll also be putting a dish of ona gel in each room for extra smell prevention.
Thoughts? Concerns?

Finally got it
I'll add some fans inside the rooms
Now that I have all the plans layed out, I've gotta order everything and put it all together.
I'll keep you posted
EDIT: yeah im also ditching the 85W CLF and the timer for it. Gotta save $

Would I have to vent air up to the lights if I decide to run LEDs?
Or could I just set the 1st fan on the ground right next to the first FAE site, get rid of the venting completely and have the 2nd fan remain in the same location?
I'd be getting rid of vents and moving the first fan to the circled area to pull in air

LEDs is cutting corners? I was under the impression they were better 
So that's basically a hell fucking no to LED's?
It's not completely my choice but I'll do everything I can to sway the decision to the typical MH/HPS.

Thanks for the advice for the lighting. I'm reducing my flower plant count from 11 to 7. I made up for this in the PVC system by replacing the four outer tees with elbows and eliminating the outer corners used as 4 extra plant sites. I'm thinking it should work exactly the same.
I know your general rule of thumb is you want a res to be at least 2x the amount of water needed to flood. I however have no idea how I would calculate this number But would you say maybe 15 gallons be good?
Also since I'll be using the 324W 30,000lumen t5 instead of the MH, it will have a self contained ballast so the buffer room will only consist of the carbon filter and the HPS ballast. I'm thinking I'm going to soundproof the buffer room.

Got a 27 gallon instead, it looked sturdy and was a good size to set the PVC thing on top of. I sealed the PVC together and have ordered some items but I still need to order a lot more.

Will these rocks (river pebbles)
Work instead of using hydroton?
