For a 10x21x13ft room, how big of a lung room would be needed? I have a decent extra space.
Depends on how much of said area you plan to grow in , but rule of thumb has always been lung area`s always equal to the sq ftg of all grow areas involved....in my case...For a 10x21x13ft room, how big of a lung room would be needed? I have a decent extra space.

I had side by side fliprooms that had outside dimensions of 8x16 , but the enclosed areas averaged 12x30 , and the clone and pre-veg cabs only took up 10 sq ft so my lung areas were waaay overkill , but overkill`s underrated......so....
360-138=222 sq ft of pre-conditioned "perfect environment" bein pumped in and sucked out of 72 sq ft inside dimensions of the fliprooms twice per min FTW.....
Any other questions about anything other than Dabs setup , please hit me in pm so as ta not clog up the thread ....
Peace...DHF..........
600ppm on .7 or .5 scale? i dunno your strains, but many of mine would need at least 900 on the .7 scale by flip. especially my 5gal 4 footers, they were at 1050ppm first 3 weeks flower. 5-700ppm runoff everyday.
~30% RH? could ya raise that?
Some pics would help man...... that said it's likely your humidity being so low. Buckets/totes full of water with aquarium heaters on high, and fan blowing across the water will help raise humidity some on the cheap. Though ultimately you should have researched this project better, and allotted budget for pond foggers. Tossing this many lights in one room changes the dynamics a lot over just a few lights.
Edit - Freds has much better explanation.
I think if yas back off on the feed , they`ll start cyclin out , and yes.....In all honesty, my first grow had super low humidity, so i figured i could skate on this one..I kinda just assumed as the room got more foliation the humidity would rise and become less of a problem
I think if yas back off on the feed , they`ll start cyclin out , and yes.....
In a dialed environment as the plants suck juice and sweat it out , guaranteed RH will be increased , but with major airflow and exchange in low RH environment along with mega wattage , RH supplement is mandatory and will help yas next run ......
I just hope that`s all it is.....
Good luck....DHF...........
sorry to hear of the growing pains dabs,I have a few myself...not trying to steal the thunder here
but I'm also dealing with a bit of low/rh-VPD in a sealed room,
nothing as severe as dabs,
i'm @ 55-60% but i want to get the room dialed best i can is this is the only weak link in the chain...so far
looking at a couple pond foggers @$128ish that were linked to a few pages back
it seems something like this is the best option all the way around?

I think it'll do what i need also dabs. but even in your situation 2 foggerz against one of these still seem to be a better option?
its sez it'll do 160-340sqft depending on humidification requirements and ceiling height,
it does .4gal per hr.... so a qt an hr..
DHF also mention about a DIY yourself humidifier bobblehead made
best of luck Dabs
btw i was getting the leaf VPD curl and was feeding heavy,
cut the fertz and only water and liquid karma and root stimulator and all the curl is gone in a week or less
DHF mentioned that a few posts back, man definitely kno's his stuff
Ok.....sounds like classic VPD issues combined with overwatering , but I`ve been wrong before.........
With humidity that low the plants stomata are all but closed to "prevent" excess transpiration and preserve plant tissue moisture , so with yas feedin their ass 3 times a day , they`re not eating/drinking and most likely residual salt buildup and ph lockouts are right around the corner , IF that`s the issue...
With the size of those plants and lights off RH only risin up 9% is an indicator IME....
I know with that much perlite you feel the need to keep the medium pulsed like D9`s PPK setup , but if RH ain`t where it needs ta be , the only alternative is back off on the feed sequences and see if they start drinkin and sweatin again....
Check runoff ppm`s and ph , check rootzones fer critters , let em dry out a lil bit , and hopefully they`ll come around....Pot`s a resilient plant and can grow AND finish under extreme conditions , just won`t finish well and might spit nanners , so check for plants hermie`n as well once initial bud set hits......Core ph and ppm levels are the best wayta check what the plants are exposed to with a slurry test....
Getchas some fogger my buddy as budget permits....You won`t believe how well they do in a dialed "moist" environment with proper watts per sq ft......anyways....Hope they perk back up Dabs.....
Peace....DHF............
How is that possible?
Do you have more than one meter in there?
