My closet grow

Hi everyone.
This i my first time. So any good advice or tricks will surely help.
I had some issues with the temp and humidity. But i think, i might found out a way to increase humidity. so for now i just have to wait and see. My temp is around 30'Celsius and the humidity is around 30-40%
For veg. i have a 250W CFL. And for bloom i got 2*200W CFL.
In each room there are four, 80mm computer fans. 2 air-in and 2 air-out.
I'm very interested in what you think about my grow closet. So feel free to write all your thoughts.

A week ago from today i planted, 9 Ak47xLowryder. Fem and autoflow. I don't have any pictures of the plants yet. but soon.

looks good and clean, welcome to RIU

I am liking what I see but worried about the lighting. It shows you did your homework and you've got nice bulbs but I'd be worried you might not have enough light. How many lumens do the bulbs put out? Keep in mind that outside in the daylight that's around 10,000 lumens. So to break it down let's say hypothetically you got a plant in one of the chambers of your closet. That one plant is in that one chamber under a bulb putting out let's say 5000 lumens. Light disapates over distance meaning the waves that make it to the plant will be weaker than 5000 lumens. That plant will also have leafs all over, and you have your light mounted up top. The leafs up top will be blocking light to the leafs below. Light emitted from cfl's does not penetrate through leafs very well either. So that hypothetical 5000 lumen bulb sits over a plant, the plants highest leafs closest to the bulb aren't even getting 5000 lumens, and blocking the leafs below. So any light coming to the bottom most leafs is that reflected from the walls, and has traveled from the bulb to wall to another wall then hits those leafs. That light may have traveled more feet from bulb to leaf than the box is tall!! So one plant sitting under a 5000 lumens bulb doesn't even get 5000 lumens to ANY part of it, and will leave the plant starving for light. So yeah in summation you are on the right track but you WILL want more lights in each chamber

I found out that the 250w veg bulb. produces 19.500 lumen. and the 200W bloom bulbs produces 13.000 lumen, each. so 26.000 lumen for the bloom.
I have never heard of lumen? But what your saying makes totally sense. But isn't the lumen i got in the bulbs enough? Cause if i had to get another bulb inthere, i think it might get to hot. And im already struggling with the heat/humidity.

Looking like you intend to veg on top, flower on bottom?
Looking at pic #6, are the 2 top fans exhaust, bottom intake?
The shelf use to seperate looks to be set back a bit to allow for ventilation?
If that's so, you are going to have issues keeping your 18/6 veg light out of your 12/12 flower area.
If you're not intending veg and flower at the same time no prob, but why bother with seperate areas?

On the fans,, if you have issues now with heat, it'll be multiplied when you get some heating up leafs growing in there. Especially the flower room.

Not seeing anything for oder control either.

How big are those boxes and what style are you intending to grow with? I can see that working better for some methods than others.
Lighting is good if you don't try for anything over 18" or so max. Which is fine. You'll just need to hit 12/12 at 8-10" max.

More ventilation
Keep the veg light out of the flower room
Maybe a carbon scrubber / filter

Nice start. You're way ahead of where I started! Nice work.

Good luck.

Very nice;

Yes im going to Veg at the top, and flower in the bottom.
The two "boxes" is independent. So the fans in the bottom is intake, and in the top its exhaust, in each "box".
According to light, there isn't any way the veg light can come into the flower "box" or reversed.
On the back of each fan i got this carbon filter and just cut out some pieces. http://stoevsugerposer.dk/filtre-378/emhaettefiltre-379/blomberg-98/blomberg-kulfilter-8-569.html
Odor control i actually don't know what to do, and how to do it? And i was wondering, if i got more ventilation. Then wouldn't the humidity drop?
The only reason why i have chosen to run the rooms separate, is for faster harvest

Okay your bulbs are indeed very nice with those I agree with the earlier post, they'll do an 18inch for sure. But I've a new concern...with one cabinet hosting two plants on different light cycles, what are you to do if you need to get to one plant during the other plants lights out time? With ventilation yer ok but just make sure outside light doesn't make it's way through the exhaust ports.

there's a good point. it could be remedied with separate doors, though. i'm also going to reccomend additional light, but you can get away with only adding extra light in the flower chamber. the veg chamber will be fine.

Thats a Nice setup you got there. Also a lil tip, this is just from looking at it, If you were to flower on top and veg on the bottom you might be able to bring down the temps a bit, don't know for sure but air will circulate cooler from one bulb up rather than two. Oh and you could just velcro a screen with panda or something for the night cycle chamber and incorporate a light trap somehow for air..... Now lets see some life in there.

Oh earlier u said u weren't familiar with lumens. Simply put they are units of light measurement. *But if you're addicted to information like myself, sometimes simple is unsatisfactory. Here's some learnin:

A lumen is a unit of standard measurement used to describe how much light is contained in a certain area. The lumen is part of a group of standard measurements known as the photometry group, which measure different aspects of light. This group also includes such units as the candela, which measures luminance, and the lux, which measures illuminance.

Strictly speaking, a lumen is defined as one candela multiplied by one steradian, which can be expressed as: 1(lm) = 1(cd) x 1(sr). A related unit of measurement — although not part of the standard units — is the foot-candle, which is often used in photography and film. To really understand what a lumen is, it is important to understand these units: the candela, the foot-candle, the steradian, and the lux.

Although not entirely necessary to understand the lumen, there is an important distinction to be made between measures of radiance and measures of illuminance. When measuring radiance, you are basically looking at how much energy a light source is releasing directly. You’re not interested in what happens to that energy as it leaves the source, just in how much is at the source itself. When you’re measuring illuminance, by contrast, you are looking at how much of that energy makes it to a given object.

The foot-candle, also spelled footcandle, is the non-standard measure of illuminance, basically defined as how much light would strike the inner surface of a sphere one foot in radius if it were lit by a single candle in the center of that sphere. The lux is the standard measure of illuminance, and can be defined simply as how much light would strike a similar sphere of one meter in radius. The two can be converted simply, with 10.76 lux to one foot-candle.

Both the foot-candle and the lux make use of a measure of luminous intensity, called the candela. The candela was originally called the candlepower and simply referred to the amount of luminous energy emitted by a known type of candle. Later, when it was standardized, a definition was chosen that would approximate the older definition, so that existing equations could remain the same. The modern definition of the candela has to do with the radiation emitted by 1/60 of a single square centimeter of platinum when it is at its melting point.

A steradian is a standard unit of measurement used to define a solid angle. The technical definition of a steradian is the solid angle subtended at the center of a sphere of radius r by a portion of the surface of the sphere having an area of r2. In this definition, subtended has to do with the relationship between the length of the arc and the resulting angle. The steradian is unitless and is represented by the abbreviation sr. Mathematically, using the meter as a unit of measurement, we can then define a steradian as 1(sr) = m2 x m-1.

So, taking all of this together, we can now interpret our original definition of a lumen as 1(lm) = 1(cd) x 1(sr). One lumen in this case is a measure of the amount of luminous flux emitted into an area by 1/60 of a single square centimeter of platinum at its melting point into a certain angle. A lumen measurement is often used along with wattage to determine the luminous efficiency of a light-emitting body.

For example, a normal 100 watt light-bulb has a luminous efficiency of about 17.5, emitting 1750 lumens of light. A 13 watt fluorescent bulb, by contrast, has an efficiency of about 56, emitting around 730 lumens of light. The sun, in contrast, has an efficiency of around 93.

Yes well said, let's see some plants in there. It's your first grow, this is the time to get some girls in there and just see what happens! Keep us posted bro

The door is in one pieces. So if i need to check the veg, then the flower box is also open. I can't do anything with the door, cause im living home with my parents.
I'll upload some pictures later on today.
And why can it be at the day when the light is on, the humidity is only around 30-35. But when the light is off, the max humidity my measurement has measuret in the box is 75% ?????

Hi Dude, Just came across your thread looking good mate, In the space that your using them, those CFL's will work great!! Be careful not to veg beyond 7" though as when they go into flower they get pretty big..The canopy thickens and light penetration is limited to the top ft or so! And only top once or twice!

Have you considered using PVC/plastic black-out sheeting & velcro - to individually cover the top and bottom section's? .. By doing this you can open the main door and not worry about viewing both grow's at the same time Also for night gardening you could install small low watt green lamp's in both compartments (Green light doesn't effect plants photo-period) so under green light you can work on them whilst they are sleeping

However I do think 9X AK is a little ambitious for the size of your cab...I'd say Veg 2-4, Flower 2-4, or over crowding,light penetration and mould could become an issue Remember the bigger your plants are the harder it is for the fans to move the air.

Is smell going to be an issue... In Veg you are relatively safe but even in early stages of flower they begin to "STINK" Have you got any kind of Carbon Filter? I think you can get away with using an overhead cooker air extraction filter They are pretty cheap and they sell them in most DIY stores, So you won't get "para" when paying for it this could really help you out and keep your cab more stealth

You can raise humidity by placing a bowl/jug of water along side your ladies, when the room heats from the lights, the water slowly evaporates and gradually raises the humidity level in the room, Veg plants need a fairly high humidity and Flowering plants need a fairly low humidity so only place a bowl/jug of water in the Vegging section .. To much humidity in the Flowering section can promote mould on your buds (Not cool, big health hazard!)

If you find heats an issue you could size up your in and outtake fans for a faster air exchange,and add a fan speed controller to gain control of perfect temps or use some kind of hose or ducting attached to your intake and have the other end drawing in cool air from either an air vent,boarded up chimney +hole, slightly open window etc etc... and this will ultimately cool your lighting+room temps alot better.

I dont think that changing flowering to top and veg to bottom will help to much! Because your using CFLs the heated generated isn't as hot as that of an HPS/MH and despite heat rising your Veg cycle is on for a duration of 18/6 ..meaning when you flowering plant expect a slight decrease in heat for their night period, the Flowering cab fans will draw in the elevated Veg room's expelled air and be too warm..Also What you could do is use small ducting lengths to pull the air in from another side of your cab..(So one cab isn't pulling in the other cabs expelled air)

I am looking forward to seeing you put the girls in there, I hope I've been of some help, and if I can help you further in any way I will REP for a good start, hope to see more soon - STELTHY

That part with the velcro sounds nice. But where do i get it? I'm from denmark, so we don't have all those DIY stores and all that. Mostly i buy the things online.
And with the humidity i have tried almost everything now, and nothing seems to help. I read somewhere that if i took a wet sponge and put it into a plastic bag with some holes. then that would increase the humidity. But that didn't really work. Also i tried to put a cup of water inthere. No help at all. But today i just tried to put some ice cubes inthere. But when i got home 4 hours later, then the cubes were already melted. But it got the humidity up at 48%
And what about my fans? Should they run 24/7 or how? I really hate this humidity problem. so is it that big of a deal?
Now i finally got some pictures of the girls. one of them died before it came up. So it's only 8 Ak47xLowryder now. But in pic #1 you can see the sponges.

I was also wondering... If i got more fans inthere. wouldn't the humidity be "sucked" out? (Maybe a newb question)
I'm very pleased for all the help your offering me. Cause i can sure use it! And what is that "REP" thing?

I sure will! But all that information about the lumen isn't no good for me. My English isn't that great. So theres a lot of words in the text i don't understand fully But thanks anyway

You can most likely get it on E-Bay or any good Hydroponics Store on-line Another Good way to raise the Humidity is put a bowl of water in there and use a fogger (the sort you'd put in a reptile enclosure) This WILL definately raise the humidity

Its only really worth running your fans whilst the lights are on. at night the humidity levels usually rise any way so that will help you too. Put the fans on a timer and start them 5 mins before lights on and set them to turn off 5 mins after lights off!

I still think you should have no more than 4 in each compartment, You will pull more bud off 4 plants with room to grow than 8 that have no room...Trust me they will get big as time goes by! This is an important factor as you'll learn when they whilst they are growing - STELTHY

I wouldn't get more fans maybe just slightly bigger ones, not only will it be less work installing them but they'll work more efficiently too. Also wire your in and out fans together, this will help you achieve a more stable negative pressure and thats always a good thing . The other thing you can do to raise humidity is have other 'normal' plants in your actual room, ones with lots of leaves... Your actual rooms humidity will be raised and so when your grow cab pulls in air - The o2 will already contain moisture and so the levels will raise even if you have bigger fan's

I enjoy helping people, it makes me happy lol and gives me something to do inbetween my MONDAY UPDATES So if you ever need any help don't hesitate to ask.. The worst I can say is : I don't know!! lol But I doubt that'll happen.

Note:- Rep is where you click on the star in the bottom left of a post that you happen to think deserves a 'Cyber' pat on the back for doing a good job, and pretty much sets the standard between the men and the boys lol so the better stuff you achieve the more REP you should/will get and so on.... The REP you have earned is displayed in the top left of your post and is measured in green square dots

Once again hope this has been helpful to you - STELTHY

When you say i have to wire in- and out air together.. Then do you mean that i have to make the air from the "box" go out of the exhaust-, and into the intake fans?
and if thats so, wouldn't that increase my temp, and decrease my humidity?
I maybe found a place to buy some velcro tape. But what kind of "sheet" do i use to cover the lights from the "boxes"? (A picture or link will surely help)
And where do i find a small fogger? Can't seem to find anything that fits for my "boxes"
Hope it wasn't to many questions. But just take your time to answer
Every single advice is really helpful! You seem to now what your talking about. So i'll give you a so called REP as well
