co2 controller help !

Guest

In my experience with a sealed room RH rises as much as 25% shortly after the lights go out and a window unit has to be supplemented with a dehumid,I don't know about split units

ok i will def get myself the big ass dehumid , thanks chaps !
i actually have a co2 burner stashed away somewhere but it doesnt have a ppm counter or anything to controll it , i have to put a timer on it
(http://www.growell.co.uk/p/0899/CO2-Growth-Gas-Generator.html)
is this what you mean ? is it good enough ? do you think i can get an add on ppm controller for it ? it used to come in handy in winter , i just ran it lights out to keep the temps up !

as far as ac goes i am having trouble sourcing a self install unit with enough btu to cover the possible temp issues , the max i can find at the moment is 9000btu so i would have to have multiples of these and that would look a bit weird if anyone ever caught sight of one room with shitloads of ac units lined up outside lol
i was actually thinking of eventually running 16 x 600 lights over 4 - 8x4 tables ,dripper fed coco.
i have 4 150 rucks and am planning on one aircooling every 4 lights ,

it maybe would look a bit suspicious with the bottled co2 if i had to buy a massive amount , anyone any idea of how many 30kg bottles per grow with this kind of set up ?

I wouldn't even consider it man,bottled gas is a pain in the ass..People make an issue over heat and generators which is totally unwarranted IMO,for a big grow you don't want gas man.Something you mentioned about running a burner with lights out pushes me to bring up a point that can be useful.Growing plants especially stretching plants during 12/12 put off a ton of co2 during lights out.I'd check my cap in the morning and 2500PPM was common so be aware in a sealed room enrichment normally isnt necessary when the lights come on.Thats why a controller is so important man my cyclestat would kick in at lights on and waste more propane.Besides that a controller keeps you to within around 200PPM of setpoint,extremely important for good results.Wide co2 fluctuations are not beneficial and thats what you get with a cyclestat timer.Get a burner and a controller or don't even bother is my advice after years of using cyclestats,portable AC's,I can go on and on with the mistakes haha.You will end with 2 lb per 1K with persistence though.

Those are some monster bottles. My educated guess would be one bottle per week considering 9600 watts growing. Make sure the room/lights are very sealed so none is wasted.

btw..That Evolution controller should work fine so long as you get the sensor.

On another note:

Does anyone find it odd that a guy who is planning a 9600 watt commercial grow would ask such newbyish questions? Something is not right. Lets see some pictures Skins.

i am asking for help and advice for something i am planning regarding co2 and aircon which if you read i said i have no experience of !
i have said i know nothing about them that is why i am asking the people who do !
so you can think what you like mate but if you do not want to help then please dont interfere either !
and please tell which bit of growing related newbishness you have seen to ring alarm bells ? other than the admitted lack of knowledge ?

the whole point in me asking the people who know and thinking aloud is to save me buying equipment that is wrong for the job and wasting time ****ing things up when there are willing people here that can maybe help ?

sorry the ac question was on another thread http://www.icmag.com/ic/showthread.php?t=67064

BD I've been growing for years and if you think I'd post my felonies for posterity you are sadly mistaken.Never judge a book by it's lack of covers..We all have decisions to make

there are lots of reasons why i do not post pics , all of them security issues !
the only time i post pics is when i have a plant illness and need help with a diagnosis .
and i only post for information , help or to compliment , feel free to look through my posts !
i only actually found this site because of the generator thread started by I.M.BOGGLED and continued by golddust woman , and it seemed a good place to learn and share .

thanks for the input the american , i am europe based and most of the best kit i find is in the US and 120v and we are 240 v so is no good to me !
i have been looking for window ac as bignugget suggested but cannot find any and i think the other ac will extract the co2 ?
any ideas on compatible aircon anyone ? ive been thinking of trying to run the aircon in a seperate room and pumping the cooler air through my aircooled lights instead of in the room itself ?
well winter is coming pretty fast here so i shouldnt need it for for a while hopefully , but it would be nice to be prepared .

You can buy a step up transformer for $50. or less which will allow you to run 120V on 240...or vice versa.I have a step down one for 240 to 120V..just do a Google search for step up...down transformers..

hahahhha nice one jarff i didnt think of that for some reason ! thanks alot

i have been looking at a few gas burners and the biggest , easiest available one is a GAS PRO 12 burner unit ?
does anyone have any experience of these ? i was looking for a blueox as i have heard of these before but getting one in or to europe doesnt seem very easy ! and to be honest apart from the colour they look and perform the same from what i can read !

edit - just found a blueox seller willing to send internationally !

which would be the better choice ? anyone know ?

To be honest Skins,,Every one of your questions can have several good answers. One has to consider the whole picture including details of the room.

ok blinddate i have two possible rooms available , one is roughly 5x5m and the other is 8x7m . i have 80- 90 amps available my initial thinking was to use the bigger of the 2 rooms in winter only and use eventually 24 lights ! this i extraction cooled growing i can handle easily , but that is a shitload of air cooling and hot air venting in winter. which is a problem unless it goes up a chimney like smoke so doesnt attract any attention if seen !
but on reading the WPSF needed with co2 enrichment , i am thinking i could use the smaller room which is a seperate farm building with eventually 16x600 and aircon and completely seal it .
it is the top level of a 2 story building i could put the outside bit of the split aircon on the roof out of sight and carry on as normal with no real security worries !
this is why i am trying to get some other peoples angles on this venture , as the co2 , aircon etc are an idea that has just occured to me , they where not even considered in my original thinking .
and i tried not to mention the potential wattage use as i knew this would attract unwanted attention !
i have now found available aircon with split self install units up to 36000 btu which is a bonus .

thanks jarff i got 4x 600 running all year round at the moment but come winter it gets as low as -20 here :nono: , i have to nearly stop my extraction to keep the temps anything like right !
i cannot add any extra heating as i am running off a very limited electric supply at the moment .
the power for the bigger set up is generator supplied and gives me 80amps of 230v to play with , so if i am running it i may aswell use it all :joint: .
then i can just run a couple of grows through the winter and enjoy the summer outdoors !

help needed again !
i just got the prices in on propane and co2 , co2 per 30kg is cheaper by about a third ?
so does anyone know roughly which will be more economical ? how long roughly will i get from 30kg of each with a 5m x 5m room and say 12 lights for now ?
if it would be the same then it is more economical for me to go with co2 !
not as easily explainable to nosey people but the co2 is in slightly smaller bottles is easier to hide, no fire risk and less heat to aircon cool !
if anyone knows anything can you please give me some feedback as i just got a chance of a few co2 bottles cheap and have to decide pretty quickly which way to go !

thank you
