The more I see the less I know. Endless quantity of things to learn about this trade. You are doing good Benny! I have never heard of VPD, now I too have another 3 hours of reading. Thanks a lot!

I setup one of my tents to place all my vegging plants in it. It holds in the humidity a lot better. Now Im back up at 74f and 62-65%RH.

I also placed a humidifier in the bloom room which raised the rh to about 58-60%. Now I just have a figure out a way to auto fill the reserv on the humidifier. I cant believe how bad low RH is for the plants. My RH in bloom was around 30-35% and according to all the fact concerning VPD, that is horrible and can really really stunt growth and cause lock outs.

Hey Bro....Waaaaay back when I started growin inside , Krusty beat 70% RH throughout the whole grow start to finish into all us bucketheads by any and all means necessary to create "perfect environment" that big plants could thrive and produce in.....

Where I live and grew RH stays 80-90% yr round , so with all my airflow and bare bulbs , I kept RH in the 70`s till end of stretch , and as low below 50% till end of cycle again by any and all means necessary.....

Foggers work well in low RH environments , and where I spent mega bucks payin for dehueys and power draw , ya`ll are tryin ta get hold of what I was always tryin ta get rid of....lol....anyways....

VPD/vapor pressure deficit was never explained scientifically to me until maybe 7 yrs ago by a science geek know-it-all that had major book learnin , but couldn`t grow his way out of a paper sack and slung absolutes around like He was God that eventually got him banned from several weedsites , but I digress....

Point blank ....Knowin what to do through each season where you live geographically with indoor growin is paramount in importance as far as creating "perfect environment" 12 months a yr for optimum performance and production out yo bitches aight ?....

Environment`s waaaaay more important than slingin light at their ass , but dialed room conditions and proper watts per sq ft will make yas happy with the right hybrid for the job.......

Keep dialin Benny......You`re getting there......Sooner or later I`ll talk yas into getting rid of the "fool" tubes , and swappin over to D9`s PPK system....lol.....

Bare bulbs rule.....all else drool.........

Good luck and respect Bro....DHF.........

 

[sahdgrower]

darn you dhf!!!! now I have more to read... plus the stupid D9 threads pictures wont show for some reason, so I have to dig even deeper just to find out what the hell a ppk system is/looks like!

DHF, your style of writing makes me laugh man...I for real LOL'ed a few times....."Environment`s waaaaay more important than slingin light at their ass"...hahaha I busted out.

lol a lot of peeps hate on that cooltube. I think something about it just hangin' there pisses common folk off...haha atleast it is vertical and my other two are bare, just how we like'em

Here is a damn good read on VPD with some awesome charts:
http://www.just4growers.com/stream/...-deficit-the-hidden-force-on-your-plants.aspx

And I side note....Colorado Amendment 64...cats of any size, any color, can now walk into any dispensary and buy some ganja. That shit is perplexing and makes me worry about the future profit margins. I saw some pic of this dudes face buying pot for the first time. He had that oh shit deer stuck in head lights look on his face.

 

[sahdgrower]

Good thing for me if value goes down, then I could just grow it outside in my garden and not have to worry about thieves. I could grow some effin monsters in my yard.

 

[Bennyweed1]

Well shit, the plants are noticeably happier after amping up the RH. I cant believe how long I have been growing thinking RH wasnt that important as long as it was on the low side.

Here are the veggin girls moved into the veg tent. 68%RH @70f.

And here are the next batch in pre veg

 

[Bennyweed1]

And here are the plants in bloom. The second set of plants are looking great although I wish they were larger. Ill get'em there soon.

 

[Bennyweed1]

And here is the first set that I made a lot of mistake with. I am surprised that they are actually gonna yield something after what I did to'em

And I forgot to ask this before. About those Ultrasonic foggers, how the hell ya control them? What do you place them in that will last a few days between refills? Any advice would rock.

Hey IC, I need help. WTF is this thing? : http://www.ebay.com/itm/Autopilot-D...7311617?pt=US_Hydroponics&hash=item2ec2d62c81

I have been on a mission to solve my VPD issue. NONE stop, no joke. My regular humidifier sucks, it needs to refilled every 10 hours. That is not practical and none sustainable.

The only thing I can reasonably come up with is using a ultra sonic fogger submerged in a 5 gallon bucket attached to a float valve controlled via a humidity controller.

Here is my hiccup. If I am going to spend the money on a controller, I want to get something that has the potential to control it all. Temp, air, humidity, dehum, co2, photo censors....the works.

So back to my original question. WTF is that thing I linked too? It cant do all that for the price it is being sold for, can it? I cant interpret its board wording "The DEC coordinates the use of supplemental CO2 injection within the temperature function". Great, but wtf does that mean? Coordinates, I can coordinate a dance rehearsal but that doesnt mean shit becasue I cant dance.

I have a water cooled co2 burner collecting dust because I dont have a controller but I wouldnt mind getting it working again...along side with getting this VPD thing under control

 

[sahdgrower]

Well what jumped out at me is that controller you linked to does not measure co2 ppm. It will only turn on and off your co2 device per your settings and will coordinate with your exhaust fans so you don't run co2 while exhausting (unless you tell it that its ok to run at the same time)

You done said the damn thang!

I figured that but how does it turn it on and off? Like I understand through relays yada yada yada but you obvisouly need a second controller. What do you do then, plug the co2 controller into this controller? What they hell is the point of being able to turn co2 on and off with out controlling it? I'd friggin kill everything!

 

[Bennyweed1]

I harvest my first batch that I put through the ringer. I originally thought all three plants were a bust but looks like they are gonna yield around 6oz total. Far ways from my 1lb goal every 4 weeks but I will get there.....

The larger four in are 4 weeks today.

 

[Bennyweed1]

Here are the new plants loaded in today. Still not as big as I want them but I finally have my veg department caught up so hopefully ill be able to get some bigger girls before flower.

You want to get a Sentinal CHHC-1 Total Environment Computer.
These are awesome.

I plan on buying one once I get a new spot. What I have to work with now doesnt allow my to setup a real room with the correct seal-ability. I have panda film walls with loose gaps which is the main reason I am not running my co2 gen. Well that and the fact I dont have a controller anymore.

The chhc-1 is badass for sure. Do you own one?

 

[OvergrowDaWorld]

Yes. I used too.
I had/have a CHHC-1, EVC-2, and PPM-1 environment controllers.
The EVC-2 and PPM-1 work hand in hand with eachother.
Since I could only run so many things off the CHHC-1, it popped the breaker sometimes, so I got the 2 controllers that work together so I didnt overload the thing anymore.
I ended up selling the CHHC-1 and just have the other two now.
I also use 2- PXM-1 power expanders. Love these things.

good stuff man, here is my next question. What type of power source does it plug into too? 120v or 240v? Being able to power both A/C and humidity could easily be more than 20a if running 120v when both are running at the same time.

Also, does the humidity feature also have an operation to work as a dehumidifier? In the summer I willhave to lower RH and winter I will need to raise it. I am assuming it does but I dont know.

 

[Bennyweed1]

Never mind...I just rad it can only run 14.5a @120v.

The A/C unit im eye balling is 10.8a and my dehumidify is 5.5a, now you gotta weigh in fans and heating. How do you power it all with this device?
