Equipment options?

[FruityBud]

Hello to all.

I'm ready to start to get supplies and put things together, but unsure about a few things first. With the information I have below, what would be the best option for an ideal setup.

Going with a 250w HPS/MH Lumatek ballast.

I have a choice of reflectors to choose from, but not sure which one to pick:

Adjust-A-Wing
Aerowing
Cool Tube 125mm
Mantis 250/600w

Size of my grow box 2x2x6

Going with a 4" extractor fan, my options for the fan are;

S&P TD-160/100, 100mm/4inch Airflow:160m3/hr
S&P TD-250/100, 100mm/4inch Airflow:250m3/hr

With that 4" fan, I would need 4" insulated ducting? and how many and what size would you have the passive intakes as?

For filter, the one they have at my local is called Fresh Filter, anyone heard of or use one? they come in these size's; 100mm, 125mm and 150mm, I'm guesing I need to get the 100mm?

Any more information needed, just ask.

Thanks.

im taking it your room dimensions are in feet. So we need to change the fan speed into ft3/m to make it easier. your 160m3/h = 94ft3/m and your 250m3/h is 147ft3/m.

You have 24 ft3 in the box and you want to change the air between 3-5 times a min.

A filter will reduce the pull a little so compensate for that. I would go with the 250m3/h and 100mm filter. with out the filter it is changing air 6 times a min, add the filter to that you should still get 4-5 times a min.

Those numbers are incorrect. You want to remove all of the air in the room once in three to five minutes.

This is being incorrectly stated here continuously and is Not the industry standard.

I have read on many sites, and have had advise from many people about the air exchange and you are the only one ever to tell me once every 3-5 min.

If you changed the air once every 3-5 min in that grow area i would bet you would have problems with humidity and heat.

I'm sure someone else will comment about this. for now i stick by 3-5 times a minute.

How many sources would you like before you agree you have the incorrect information?

Got an Ipad I'll send you a link to a grow room calculator?

first source - hxxp://www.marijuana-seeds.net/OdorControl.htm - and I quote "The filter size required for you application will depend on the amount of air flow required for your application. Two rules of thumb are to maintain an air flow that is eight to ten times the total volume of your vented space per hour, or, for indoor growing applications, 150 CFM per 1000 watt light bulb"

second source - hxxp://hydroponicsdictionary.com/index.php?s=air+exchange - and I quote "General Hydroponics Carbon Air Filters work with any popular inline fan. Calculate the size of your room and choose a fan that completely exchanges the air in the room eight to ten times per hour. Then choose the appropriate filter with the correct CFM and flange size to match that fan.

Third source - hxxp://www.atlantishydroponics.com/Carbon-Filters-and-Air-Purification/Carbon-Filters-and-Air-Purification.asp

Humidity and Heat only come in to play if those issues were not set up properly to begin with but do not play a part in proper air exchange calculations for thriving plants. When we talk about air exchange and what is needed the calculation is based on the amount of air that is removed and brought back in to a room in order to keep CO2 levels where they need to be, or should I say at a level where plants can thrive.

 

[Jericho]

Seem to be getting a little hostile pete. Ok you are right. For the plant to thrive that may be the right amount of air exchange needed. What do you do then if you would like to cool the room or lower the humidity by exchanging air faster?

People do not only use there fan systems to correct the amount of CO2 in there grow space. It is used for much more.

This is a forum where everyone's opinion is welcome. I have given my opinion on the matter and you have given yours. End of.

This Is my opinion made up from my experiences and the knowledge of others on the site i trust because of there hands on experience with growing. Frankly you can name as many sources as you like. It will not change my mind about it,

 

[Peter Jennings]

Why is it every time I state facts people say I am being hostile? I'm not even in the ballpark of being hostile. Trust me on that.

Lets me answer your question with another question. How do large companies, or any large growing operation cool and deal with humidity levels in "closed loop systems" ?

You'll find your answer there.

 

[dman1234]

i always aim for 3 times a min approx.

Let me answer you with a question. Are we companies or large growing operations here? If you want to be smart about it then answer it your self.

 

[Peter Jennings]

My point was it's done the same way. I think we can all see at this point who the one with hostility is.

 

[Jericho]

When you are being smart about your answers rather than just giving an explanation i hope my frustration does show through my posts.
If you would answer with an explanation of why it should be done like this rather that just saying i am wrong then it would be helpful.

There is no hostility in my posts just frustration from your criptic answers.

Fair enough. Thought that is what I was doing in the first post I had with sources. Did you read them?

Heading out the door now but I will be happy to explain any aspect of grow rooms. Its what I do.

 

[Jericho]

The links that you have given are just copy and pasted from hydroponic stores with reference to filtering the smell. It does not say anything about the CO2 needed for a full plant, or options to dealing with humidity or heat with a fan.

I understand your point and how you worked it out. What i am saying is that these sites are basing the calculations of exchanging air for the purpose of odour control not to deal with the above.

If you have other sources i would like to read them, i am interested in finding out more. If you have the knowledge then share please. How would you control heat in the room without the use of air exchange?

 

[FruityBud]

Thanks for the replys guys.

Jericho: Yes, dimensions are in feet.

On reflectors, I have only heard good things about the Adjust-A-Wing, but if heat will be a problem I will be kicking myself in not getting the Aerowing, I think its Air-Cooled. Has anyone used an Aerowing in an 2x2?

And would I be better off putting the fan and filter inside or outside the grow box?

Thanks again.

 

[dman1234]

filter inside room, fan outside room IMO.

I keep mine inside the tent just because i grow auto's and have allot of head room and its not far till it vents out side.

No clue about the reflectors, I prefer cooltubes

TBH if you have read any articles in Rosebug magazine, and or High Times back in the day I have been published in both. To date I have pretty much bit my tongue on my experience because I don't want to come off as arrogant because no one knew me here.

I built my first professionally built groom room in 1979, and most of the time I try an educate people based on the industry standards.

I am NARI certified, IRC certified, IIRC certified, and I carry a a class C general contractors license in three states. I am nationally certified in electrical, plumbing, and carpentry.

I some eyes that may be an arrogant post however I have tried to help people without having to go in to all these details.

Now, if you would like to sit back and learn something from a professional, I will be happy to help, but if you want to continue to jst spout off about "what you have read on other places" I will sit back and let you give the wrong info based on your second grow in a tent without anything other than your opinion.

I did say I would come back to this thread. Took me a week to think about what I wanted to say, and TBH cool off a bit.

I apologize in advance to any members who may find this post offensive.

It is/was not my intentions.

Peace,
PJ

Actually i do find you to be rather arrogant and offensive. Just to throw that out there. (My opinion)

You belittle my posts and what the people here have taught and expect your word to be taken because you are certified.
Just because you build to the industry standard does not mean you are always right.
There is more than one way to grow cannabis, no one way is right. It depends on your preference.

The thing is that you say your way is right but will still not give any explanations as to why. Just that you have been taught this way and got a certificate for doing it this way does not make it right.(My reason)

You say i have only done 2 grows, funnily enough you only know what i have told you, nothing more.

So instead of putting other members down, why don't you try giving your reason as to why your opinion would be better and then let the member asking decide what they would prefer to do. If you did that they i wouldn't find you arrogant i would find you knowledgeable.

Until you decide to give some facts as to why your option is better then i will continue to use mine and share my opinion on mine untill i am taught (with actual knowledge instead of another opinion.

This is how a forum works.

And I find you to be extremely green and ignorant on the subject at hand.

You belittle my posts and what the people here have taught and expect your word to be taken because you are certified.
You are the one out here giving people advice with the incorrect info, not I. Call it what you like. I doubt you would be so defensive if you actually had some credible sources to back your claims.

Just because you build to the industry standard does not mean you are always right.
Never claimed to always be right, but if you want to get right down to it, I am right here and you are wrong, and if you like I can dig up some other threads to show you are consistent in giving bad and incorrect advice.

There is more than one way to grow cannabis, no one way is right. It depends on your preference.
Who said anything about growing cannabis? This discussion is based on growroom air exchange, and your incorrect data.

The thing is that you say your way is right but will still not give any explanations as to why. Just that you have been taught this way and got a certificate for doing it this way does not make it right.(My reason)
You lost me here. I'll have to ask my 25 year old to better explain. Are you actually stating that someone who is trained professionally only has an opinion after 30+ years?

You say i have only done 2 grows, funnily enough you only know what i have told you, nothing more.
So r u admitting to the fact that you have told lies to all of us here now? I think it's pretty obvious to most the experience level you have, but do tell.

So instead of putting other members down, why don't you try giving your reason as to why your opinion would be better and then let the member asking decide what they would prefer to do. If you did that they i wouldn't find you arrogant i would find you knowledgeable.
Outside of you, never had anyone here make this claim. Perhaps they can chime in. My opinion happens to be backed by more than 30 years in the business. How much you have again? I am not putting you down, I am giving the correct info based on facts. I am not going to do the leg work for you, and because of your piss poor attitude will never give you advice, but I will make corrections when you spout off about something you have read about and have not done.

Until you decide to give some facts as to why your option is better then i will continue to use mine and share my opinion on mine untill i am taught (with actual knowledge instead of another opinion.
I posted some links in this thread to help explain air exchange. The fact that you don't understand the concept is on you.

Rather than just sit here and argue with me like a child, why don't you drink some of that advice you were giving before your three edits of your return to me and post up some credible links to show us all how you are correct.. :hubba:


This is how a forum works.
:chuck: I know Kung Foo

Am I out of line here MP?

Fellas...DAm!..FB can take both of your ideas and make it his own....it's not like he gonna be able to follow specs to a perfect T. Smoke a bowl....show each other up on a grow journal..........a friendly noy so friendly comp! You 2 ...2 plants of your choice......whos bud is the best....air flow and exchange are more important so lets see who's more dialed in! You can trash each other there and let FB get back to his.......dam chill! Get it up fellas! I'll subscribe........i dare ya!
