you working in sealed room right Afgan king?
what makes it sealed?

Not as good as I'd like it still have a single hose ac modified to two hoses but still pulls out some co2. Sealed means the environment is full controlled in the room. No air leaks no no nothing. Last runs I could never truly hold 1300ppm now it's holding and barely using any ac cuz it's so cold.

ok so there no sealed room if running ac?

with co2 I thought you didnt need to worry about temps as much I thought

You don't need to but I do and you can have an ac. There are ac units that exclusively re-cool the same air - central air unit, mini split, dual hose portable ac
Cool inside air but use inside air to Expell heat - single hose portable(what I got), some window ac

so it's a portable that has a hose coming out
I'm a welder by trade have co2 tanks and regulators but not a sealed room so it wouldn't be good to use unless room is sealed right.

I have my portable (1 hose) in my flower tent and set to "dry" this regulates temps for target humidity range. I exhaust it out the window and vent my tent into the room it's in. It has helped A LOT. I don't need to cool the entire house now to keep the tent in check. Before I had the A/C in the room but not the tent and it helped but not as drastic of a difference. Running 2K of HPS in my 5x9 and it's on cruise control now that I did this. I would vent my HPS out the window too (that was my plan) but it's not necessary. My temps dropped 10 degrees after doing this and taking the COB's down on one half and sticking up the second thouie.

YMMV :hump:

damn I should've kept the lil one hose ac but got the central up and running and thought I wouldn't need it oh well I'm going to gave to look to gwt another.
but I don't think temp will be an issue for me right now went out earlier and had to shut off a fan my temps were at 65 for like week old seedlimgs and month old one lookef a lil droopy running 600 w when do you think I should kick it up to 1000 have the lol seedling in there and don't wanna give them to much light I'm in a cabinet about 36"×24×8'tall

Two more questions do you believe your yield would increase if you did your temps/humidity according to the VPD chart? the night temp is still in range for it but the daytime temp is supposedly too dry by the charts I have seen. Second question, Do you believe that CO2 is necessary for high yields or is the difference negligible/good yields still attainable without it?

You want co2. Think of it as a base nutrient.

Sealed room just means that you weren't exchanging air to maintain your environmental conditions.

Keep in mind that you're running HPS in sealed hoods. That's not gonna work for everyone.

Well ya but a in tune grow room should be able to hit every mark it's harder for some than others but those are what I believe are ideal temperatures/rh to grow the best looking weed and still obtain monster yeilds. Partner does the 14 gavitas with bat wings but has the 5 ton to keep it where he wants and the 3 ton to be on dehume the whole time for what he puts in. It can be done for any size room just could be expensive depending on setup but even at warehouse had monster ass dehumidifiers taller than waist high and like 2 ft deep things would put those big rooms of 180 where ever we wanted it

And no I don't I've used it before didn't notice anything besides dealing with more pm and bud rot and yes co2 when implemented properly should add 35% yeild. That means not missing 1 day period not even 1 minute lol the time without it is losing weight

Definitely makes sense less humidity=less pm/budrot not as uch moisture for them to thrive on. Thank you

If u can keep a perfectly sterile room I can say you might do a lil better maybe but not by much and to me and from what I've noticed the dryer air causes the plants to put out more resin to protect themselves. And I haven't had any issues with anything in these parameters

Dude. Y'all are running HPS. The rest of the growing world needs different approaches.

Why tho most of the world can't afford other approaches I mean lets be honest the same room I set up for 3k fully with co2 4k watts hoods fans panda pots tupur etc.....to do led I'd have to spend a shit ton more that I don't have and most people don't have. It's close to double the cost it would be for a whole hps room sure you save on electric but not too much if you're truly trying to outperform hps or gavitas
