Can you not borrow an SLR or point and shoot camera and use the close up function?

Also have you been monitoring the relative humidity? The carbon filter won't work very well when the RH is above 75%.
 
Humidity usually doesnt hit higher than 30% in the closet unless I add a humidifier.
Its normally 22%.

Took my hood and moved it to the center of the closet (closer to the exhaust fan), and moved some things around, hoping to get optimal air movement and temperatures.

I don't have a camera, and I really don't know many people ,so, Not really many people I could ask that could have one...

The plant has started to bud a tiny bit, getting the trichs on the tops.


Im currently running my closet on 600 watts to see how the temps will hold. (Plants in another dark room)

Anywho, I get my filter tuesday, think I already said that, who knows....
Can't wait till spring or winter when heat isn't such a damn problem. lol
 
A good way to get the temperature right once you've sorted the ventilation is to slowly raise and lower the light until you get to the desired level. The main way to cool the area though is to extract the air right out of the area (into the attic in your case). If the air doesn't come out of the closet and into the attic and is just extracted into the same room your temps will remain high.

I wouldn't recommend adding a humidifier (not that you are planning on doing so) as a low RH in flower is recommended as it drastically lowers the chances of bud rot and othe pathogens taking hold.

Also, I would recommend you (no, I'd urge you) to spray your plant and innoculate your compost with a beneficial fungi as soon as you are able to. The innoculant should contain trichoderma fungi at the very least. I use Plant Magic Plus Essence which is the best product on the market at the moment when factoring in things like cost. You should be able to find a similar product quite easily. Canna do a trichoderma fungi for example, but there must be other products available in the US that contain other fungi like mycorrhizal fungi and benefical bacteria.

Also, you mentioned that your plants wilted through you failing to water it. You must at all costs avoid this if you possibly can as every time this happens you destroy many fine feeder roots which absorb nutrients etc. and your yield will diminish each and every time significantly. If watering is an issue perhaps next time you should consider using an automatic irrigation system? The Autopot waters/fertigates the potting mix or coco substrate (which works very well in the Autopot) automatically so that you only need to top up the reservoir every 7-10 days and is very cheap for what you get (it is a high quality product that many people swear by). This is such a time/life-saver that it makes growing a much easier and rewarding experience.

One more thing - as well as the ducting you'll need an quick-release clamp that fits onto the carbon filter and clamps it directly onto the fan. These are cheap.

Nice post AE. Which cannabis forums do you use, and are you growing anything at the mo?
Click to expand...

Thanks. I use lots of forums (ICMAG, Rollitup etc.).

I'm not growing right now but am preparing for a grow where two plants are in a grow wardrobe in Autopots and four are in a nutrient film technique system (the GT424 by Nutriculture). The main tent with the GT424 inside will have the Sunsystems Blockbust air-cooled hood I just bought (the best air cooled hood on the market IMO) with a 600W HID powered by a Lightwave digital ballast and the grow 'drobe will have an adustashade with a 400W HID light also with a digital ballast which I haven't purchased yet. The main tent grow tent will be started first and is almost ready. In the main tent the environmental control is an SMS COM twin controller which powers a 6" and 5" Ruck fan. I'll be using the Lucas formula in the NFT tank with GHE Flora series nutrients. I plan to use a 5" extraction fan on the drove and will be using Hesi nutrients with a medium comprised of 80% coco and 2% fytocell. I could go on but it would take ages!

I will be growing mainly Blue Cheese with some other strains SCROG style.

They are large pictures, I do apologize, but, you guys asked for good pics , tried to get em as clear as I could with my g/fs phone.


Also, I got some Purple Power plants clones, fem .
I will also be getting some Sour Diesel clones, fem.


Temps are around 80 degrees as of now, been staying around 80-84, which, isn't too bad, I can't complain.

Plants doing pretty well, didnt know that when the plant droops that it damages the roots that much...
I wasn't going to put a humidifier in there, not when flowering, I just mentioned something (dont remember what) at the time about a humidifier cause some one else had brought it up...

My next grow Im going to be trying to incorporate micro-nutrients into my soil, any suggestions for that ?( for my next plants and what I should use on the one flowering already?
Well, Ive got a head ache , gonna go smoke and get some rest, thanks for all the info & support guys. Much Appreciated, AE, its crazy how much info you've thrown in here, along with everyone else. I do appreciate it , very much.

Thanks for the kind words guys. I'll post you a link to my grow diary when I start it Wise.

Prelude, good sources of micronutrients are things like seaweed extract (get cold extracted SW extract), calcified seaweed, kelp meal (careful it's 'hot'), rock dust/azomite (which should be ground fine like flour). Seaweed products also contain growth stimulants, hormones like cytokinins etc. and other magic and wonderful substances unknown to science.

Large amounts of individual nutrients or pH imbalances in the medium can cause micronutrient lockout showing micronutrient deficiencies when there is no deficiency in the soil itself.

If you're using things like seaweed meal in an organic potting mix you need to add it to the medium and let it sit for at least four weeks so the bacteria can convert the components into plant available forms.

Things like the structure of the medium is just as important (e.g. a crumb structure medium) and having a medium that drains well in addition to retaining water sufficiently is important. These factors are just as important as micronutrients present. This is why coco, for example, gives explosive growth even though it in itself has virtually no nutrient base. Perhaps tell us what medium you're planning on using?

Your plant looks as if it has a little nutrient burn at the bottom but it's really hard to tell.

Well, Im going to continue using cocoir(Now I know to rinse it off before I plant since it has alot of salt...)

Some wormcasting, and seaweed micro nutrients I guess, Ive never seen or used it, so Idk where to get it, but Im sure I can find it somewhere.

The nute burn on the plant was from a few weeks ago, I've only nuted once since it's been in flower, today will be my second time watering with nutes during flower.

So, Calcified Seaweed? Cold Extracted seaweed extract and kelp meal?
What do you mean its hot... Rock dust? Azomite? Oh man you lost me again, hah
 
^exactly. You only need to add an extremely small quantity (1ml kelp meal per litre of medium is about right as a starting point if you're adding other nutrients!) otherwise you could suffer from nutrient burn or lockout syndrome if you start using silly doses.
 
You can SCROG single plants you know. A lot of people SCROG single plants under a single 600W HID light to produce monster plants. Single plants can produce trees with the right care and this is a great technique for people wanting to avoid getting into too much trouble from the long arm of the law (which isn't a concern for you now Prelude, you lucky bastard!). A great system for single tree plants is the Waterfarm hydroponic system made by General Hydroponics or the Autopot (which allows you to leave it for up to 10 days).

Sorry, I'm rambling!

edit:

I forgot, I wanted to talk about your passive intake Prelude. With your passive intake you ned to make sure adequate fresh air from outside of the growing area is coming in. Pulling in stale or warm air is no good and this effectively means you need to have a window open all the time so that fresh air can be drawn inside from the outdoors and into your grow area (since the ambient air pressure inside the room will drop, sucking air from the outside through the window and into your grow area (cupboard).

Also, importantly, as a general rule, passive vents need to be between 2 and 3 times the surface area of the extractor fan hole. So, because you've got an 8" extractor fan the area = π(4^2) = 50 square inches, you need a passive intake of 100 sq inches to 150 sq inches. If your passive intake is too small you will not be able to pull in enough fresh air for your plants to exchange the stale CO2-depleted hot air and as I've said, good air exchange is the most important factor in your grow by far.

The passive intake and extractor fan need to be on opposite sides otherwise you'll have a stream of air going straight from the intake to the exhaust, completely missing your plants!

Although I did say an active intake (i.e. using a fan rather than just a vent) is 'optional' but grows using active intake run much more efficiently and the exhaust fan doesn't have to work so hard and will have a longer working life.

Closet....Not cupboard...hehe , though I do have my clones growing in a cupboard now :D, so I guess you can say that. lolol.
I am pulling cool air from my room (77) and blowing it into the closet, I dont have a passive intake. I have a fan blowing into my closet, which I thought wasn't passive.
And I do open my windows at night when the lights are on if its cooler outside than it is in the house (which it has been the past week or two)
Ah, yes, I do have 'active intake' I always have a fan blowing into my closet, but I dont always have my exhaust fan on, usually just use it when the lights are on, is that okay?


Well, Got my carbon filter today, (even though it still doesnt smell, and I truly doubt this plant is going to smell much at all, I had my uncle who's grown for about 15 years come over and even he was suprised that its Northern Lights and doesnt have much scent. [the guy I got the Purple Power Plant Clones from)

Anywho, I've got my carbon filter set up, its just kinda, sitting upwards on the floor , with a fan ontop of it, pulling air through it ( I believe thats the direction the air is supposed to be flowing, but from what I've read people do it both ways but pulling air through seems to be more efficient.

Kinda weird I just have a carbon filter with a fan attatched to it blowing upwards towards the ceiling ( I guess that might help the exhaust fan remove heat a bit more as theres more air flowing up towards the area where the air is extracted anyways...)

Idk...
Im a bit irritated with myself for not planning this all out ahead of time, but I guess thats what I get for jumping in so quick, Blah, Ill get it together eventually...

^ you need your fans on 24/7. The fans are there to increase CO2 levels as much as to keep temps and RH in check. You need to have it set up so that you are extracting the air out of the room (and into the attic in your case). You need to have the window open at least slightly all the time prefferably so fresh air is sucked into the room. The extractor fan needs to suck air through ducting and into the attic via a sealed hole in the hatch leading into the attic so that there is negative pressure in the grow room and fresh air is pulled in through the open window and then the passive intake. You'll be able to grow weed with you setup but your results will be much worse than if you set it up properly. Sorry I don't mean to put you down or anything.

Edit: can you post a photo of what your setup looks like?

Well, I leave my small fan blowing on the plant on at all times, and I leave the fan blowing from my room into the closet on at all times, I just turn off the exhaust.

Anywho, I can take pics, It will be difficult with my phone and the fact that its hard to catch the whole space in one picture without being able to take the doors off of the closet (wish I kinda could just to take the pic)


I dont get it , like , I dont know what Im doing wrong, and I feel like I keep reading the same post from you over and over again....

I DO, have a fan exhausting into my attic with no leaks. its a sealed hole. I do have a fan blowing on my plants at all times. I do have a fan blowing fresh air into my closet , at all times. I do have a fan blowing on my lights upwards towards the exhaust when the lights are on, I don't believe theres any negative pressure, if anything its the other way around.
Ive got my closet door lined with black out cover plastic, and its pushing out in the bottom not sucking in.

I can't keep my window open all day as it's 100 fuckin degrees outside and my house is 78.
I have enough problems keeping the temps down when the lights are on at night.
Yeah, Ill have my window open when temps outside are nice, but not during summer, I can't do it. Its WAY to hot.

my extraction fan does suck air and pushes it out through the ducting into the attic.
Only problem is that the fan is on a shelf up high in a corner away from the lights (hence why I have a fan blowing up towards the lights in the direction of the extraction fan (if that makes sense)

Should I connect my fan and carbon filter to the extraction fan? Or is that a no-no.?. Blah
Ill try to take pics tonight, Try not to be toooo critical, as I do know its very unorganized and I had no clue as to what I was doing. lol.

(I know you're not trying to insult me, I just think were having a miscommunication. And this is my first real grow , so , Im just trying to learn what I can and do what I need to for the closet, as I am planning to grow 6 plants after this mother flowers , with SCRog, Or should I do 4 plants, its under 600 watts.
 
prelude.....I've been lurking in this thread and I see you've come a long way ..... welcome to advanced growing....:)...

When you say 'fan' do you mean an inline fan or an oscillating fan? How many inline fans are you using? You really need to upload a photo so I know what you're talking about. Only then can I really comment as there's obviously already been some miscommunication as you said, but since you don't have negative pressure in the grow room you're obviously doing something wrong. If I can see a photo then I might be able to figure out what the issue is.

You need to have the inline exchaust fan running 24/7, not just during lights on. And yes, you should connect the carbon filter to the inline exhaust fan - that's the best way to do it.
