Sealed room - controlling atmosphere

[Sudden818]

Looking for input on how to keep the veg room conditions seperate from flower room.
My entire grow area is one big sealed room 15'x6' divided into two rooms. Veg/mother/clone room 4'x6'x8' and flowering room 10'x6'x8'.
Window ac, bottled co2, chhc-4 controller in flower room.

So if I'm running 1200-1500 CO2 ppm in flower that air (because it has the AC) has to be circulated through the veg room to cool it. So I'll have 1500 in my veg/clone room. Veg room has t5's
Unless there is a way around this. Ideally, I'd love to have 300-500 in my veg and 1500 in flower.
Do I have to have the veg room on a seperate intake and exhaust (not sealed).....:(and keep the flower room sealed?this would be the Last resort
Will circulating the air with the flower room be ok or will the high co2 levels and the different atmospheric needs make it impossible to maintain ideal conditions? Ideally I want it all sealed
Any input on setup would be greatly appreciated

there is no point....

to add co2 enrichment when you are only using t5's in veg. the light output is not strong enough to warrant extra co2. i think that if you run it through your veg, you will be wasting gas.

So would I have to make an intake and exhaust for veg room only and keep the flower room sealed? Ideally I would want both rooms to be sealed though. Wasting gas is less of a concern over keeping it all sealed I do have a 400 I can use for veg but how would I keep the co2 levels in check if I just circulate Ir between both rooms?

Just asking, why do you want the veg/clone room sealed?

 

[Sudden818]

The room is built and I don't want to have to use fans and scrubbers for intake and exhaust unless there is no other choice.

I want to completely control the environment. Mainly it gets real hot in the summer where I am and I want to be able to grow year round and to control room temps easier without having to to be at the mercy of the outside air temps that the fans would be bringing in.

I wish there was some way to exchange just the right amount of air from flower room to veg room without impacting the veg plants with the high c02.That way the whole deal would be sealed.No filters and ducting on the outside for people to see.
I appreciate any feedback

C'mon farmers. Any suggestions. Need some help

Yo buddy I live in the same area you do and I veg in an open closet in a spare bed room. No intake or exhaust, no CO2. Works perfect. I just have them under a 12 bulb (usually dialed down to 8 bulbs) T5 with a small fan blowing on them. I do 12 plants 8 weeks in veg this way. Just try and keep the temps below 83 and you're good.

As far as CO2 and a sealed room... I've done it and loved it... But after killing it over the summer as well as my latest harvest without CO2 I'm not running it again with this new grow. It complicates things IMO with questionable return. That being said I'm planning on running it with my January run just to see the difference.

With CO2 (I use a CO2 burner) I have to run my A/C whenever the lights are on. Also have to run the dehumidifier most nights due to increased humidity. These make it complcated to dial in the temp without a temp. controller. Not to mention the power draw 12 hours of A/C and Dehumid add.

When I'm not running CO2 I use a 10" inline with speed controller to supply fresh air to my room. A 12" inline fan with speed controller connected to a Phresh filter exhausts my room. I don't need A/C this time a year with this system. So easy! The speed controller on my supply fan is always on the lowest setting and the exhaust is on medium. If its an exceptionally warm day I just turn up the speed controllers to refresh air faster.

Well vegging without filters is not an option for me. I don't want to contaminate plants with outside air.

So if you live in the same area as me the you know you can't grow unless you have ac but only a few months a year because outside temps are to high. Doesn't matter how big a fan you have. If the ambient air outside the tent is 95 degrees then your not getting your room any cooler than that

So looks like I have to either
A use filtered intake and exhaust for veg room/clone/mothers or
B veg and flower all in the flower room( would be able to control everything from start to finish with controller and co2 but would not be able to have clones or mothers and would delay harvest schedule or
C circulate air between veg and flower room. ( veg room would getting higher ppm air from flower room
Hmmmmmmmm???????

The way I see it is its only 95 degrees 3 months out of the year. No, I don't live in the valley thank God. So my temps are a bit cooler than the valley but this time of year they are about the same.

Right now with average temps in the mid 70's you don't need an a/c with my setup. I have one in case but haven't used it since the last heat wave a month ago. My problem has been getting the room warm enough. I've been topping out at 75 deg. and getting as low as 69 during lights on.
