Hello everyone. I first have to say that this has been the most friendly, informational and responsive forum on medical marijuana cultivation. Thank you all for your support.

I am building an 8'x8'x6.5' enclosed room in a 3D program called Maya 2010 before I actually build it for realz. I like to conceptualize for a bit before creating the final product.

I will be building the frame out of wood and lining it with visqueen plastic. I have an a/c window unit at 6500 btu's. 1100 wt hps up top and a t-12 ballast on each wall with 6 aquaponic systems on the floor growing 5 plants each.

Instead of transferring the plant from clone to veg then to flowering I plan on vegging and flowering in this same room.

In the cloning and early veg stage I will have a 4x4x6 area similar to this with a 400 wt HPS

Any suggestions on where you would put the fans with this veg/flowering room in particular?

Will the a/c unit I have be sufficient for what I have planned?

Would you do 6 different aquaponic systems or 3 or 1?

Any other info, suggests on equipment or critiques would be helpful and greatly appreciated.

Thanks in advance!

I dunno. What kind of climate are you in?

Typically, intake/outtake fans should be enough unless you live in someplace where it gets hot, like regularly >85ºF outside.

In your picture, that looks like a massive outtake fan on your ceiling? You're going to want to muffle that a little, those things are loud. If your room doesn't get really hot, you might be okay with just the outtake.

Backward Z: Thanks. It is pretty humid here all year round and gets up to the 90s regularly. In the winter it is in the 60s on the low end.

 

[Danconia]

Backward_Z: Thanks for the feedback. What size exhaust would you suggest for this set-up? It is humid here most of the time and in the 90's regularly during the summer.

Kick up the a/c some and get rid of the giant fan or keep the fan and lose the a/c. Exhaust will just suck out your a/c (aka: cash) and your a/c is borderline, unless you have a cool climate. With the money you save on the fan bump up to 12,000 btus or more. If nothing else, you will leave room for expansion.

Cool 3d mock up. I like to make a floor plan to plan out a room.

If you give a little more info on the veg room and whether your using c02 or not. Then would help more on how to give you suggestions. (ac or in/out air)

Air Conditioner is needed if you want to enhance the room with c02. Otherwise like stated you will be wasting your cool air by sucking it out of the room.

You can just use in and out air exchange to cool the room.

Should be sufficent btus for the t5's and hps. 4000btus for each 1000 watts of lighting is usually a safe estimate.

The fan can be kept for emergency exhaust (in case ac goes out) or to ventilate the room if using sulphur for example. What if you want to use a air cooled light then the exhaust fan can be used for that. Good to plan ahead before buying equipment.

If you keep it a closed enviroment room with ac and c02. You will also need to get a dehumidifier. The res will need to be in a different room if your running higher temps with c02.

I would put the fans in corners of the room and get the wind going in a circle.

Then add a carbon filter with scrubber to clean the air.

Hope that helps. I also agree you can just use in and out air but all depend on what you want to do.

sgt. schultz: Thanks for the feedback! I had the impression that air needed to be pumped in and sucked out in a room to keep the air circulating. If I don't need the exhaust then I will just cross it off the list.

leadsled: Thanks! I figured since I use this program all the time I might as well use it for this as well. I do not think I will be using co2 in this set up. I was thinking of just using some carbonated water (zero sodium of course) and spraying it on the plants a few times a day. Saw that from the Green Man video. He did both co2 canister and sprayed them down with carbonated water.

I am not using an air cooled light unit. It will be a closed environment. I want to keep it as separate as I can from my home due to having a hairy dog and high humidity where I live.

How many fans would you suggest? 1 in each corner?

Really appreciate the feedback!!

 

[leadsled]

danconia, you should choose either use in and out air for cooling or ac. Sgt stated you do not need it because you usually either go one way or the other. (in out air or ac cooling)

RE: Spraying c02 or using baking soda. Not sure that is an effective use of c02. I feel it is best to do it right. If not in the budget then make plans to walk before running.

I would imagine, You will need better c02 supplementation for a closed room. The plants will absorb all the available c02 in the room and then growth will slow. OR you need to exchange air to bring in fresh air with c02.

If you have a dog then use a hepa filter for the in and out / air flow. (and keep the dog out of the room)

You will also need a dehumidifier. To do a sealed room you need to add in the costs for a c02 controller, c02 regulator and c02 burner or tanks. Then a dehumidifier.

or in/out air. You need a air intake and air exhuast. Hepa filter on intake and carbon filter on exhuast.

I would go in/out air. Have a successful run or two, then invest in c02. Plan it out.

Suggestion:
If you setup with ac and no in/out air. What if your c02 is not enough? What will you do?

Try to plan for the what ifs? and plan for basics to get going and then what you can do as you advance.

RE:
How many fans would you suggest? 1 in each corner?

At least 2 circulating fans. One in adjacent corners.

Then possibly a fan on the floor directing air toward the ceiling. Just make sure you have good airflow.

I started with in/out air and one light. Kinda like what you got planed. after 2 runs I invested in more equipment.

Then added ac and dehuey and air cooled lights.

Hope that helps.

leadsled: Wow! Thanks so much for your input. I would rather not use a flammable substance in this room. Intake/Outtake would be best for my peace of mind.

I take it I would cover a window, create a wood box that is sucking fresh air from the outside and filtered before it gets into the room and the a carbon filter for the outtake to negate the smell.

What size fans would you suggest for the intake and outtake fan? Going to build some fans in maya today and place them around. See what you think.

Your bubba pics are absolutely fantastic. Got any pics of it dried and cured?

Just to be clear you can use c02 tanks and they emit cold gas. Or you use a c02 burner Cons they emit heat and humidity (pros: burning c02 is more cost effective and you do not have to lug in and out tanks of c02)

To start out I recommend in and out air then when you get dialed with growing then move up to c02 if you like.

Walk before you run :)

Yes you would cover the window, add a box and add a hepa filter to cover the intake. There are also some fancy hydro filters (but they cost more $$) A good hepa filter can be purchased at the hardware store.

You can have a exhuast fan and then just an intake. The air will be sucked into the room via the exhuast fan, If you do not have enough cooling or airflow then you can add a intake fan if needed. (usually is not for your size of room and lighting) Ideally your intake should be 2x the size of the exhuast/ 6" exhuast 12" intake.

for a 8'x8'x7' room (to make the math easier)
448 cfm will exchange out all the air in your room in one minute.
89.6 cfm will exchange the air in your room in 5 minutes.
Ideally you want to exchange the air in the room ever 1-5 minutes. Better to have too much power than too little in this case.

A vortex 6" 449 cfm fan should work great for your application.
Example for pricing

Thanks, got more somewhere

63 days of flowering bubba.

I would love to know how the hell you made such a clean proportioned and crisp digital mock up. Ive been trying to figure out a way to do so for like years and always end up with a mass of computer scribbles and crap. it would be so nice to be able to really see what im going for with design as opposed to seeing it in my head. any help much appreciated.

Me too?

 

[leadsled]

Camdawg and Casper he used Maya3d. (stated in first post)

A 3d software program. Not exactly cheap or a beginner program. He may use it for modeling other things and then used it to mock up his room.

Google sketch up is a free 3d program that can be used to mock up rooms.

Lets just say maya has a pretty epic learning curve but will give epic results. with more time a even more lifelike mock up could be made.

Neat to see maya used to plan a Op and best of luck getting the ball rolling, I'll be building my veg and flower rooms this Saturday, popping dank bean provided by the farm a day after or that night. Have to see if my bud and I can get it all done timely.

cheers! :beer
