Sealed Room With LED

[st0wandgrow]

I was hoping I'd pick up enough heat headroom by using LED and CO2, but that appears to be a pipe dream.

LOL is that a pun?

Why a sealed room Rrog?

Is odor your main concern?

 

[Rrog]

odor, yes.

 

[PSUAGRO.]

Your basement isn't finished Rrog(partitioned walls)??? can't "jimmy" a window AC unit in??

 

[Rrog]

No window units

 

[NanoGadget]

Is there a reason you can't just run some carbon cans and vent into the house?

 

[Rrog]

Nano- Thanks. Not venting the room this time. Stink happens, and it doesn't cool all that well

 

[NanoGadget]

I guess I have no experience with more than a couple ladies at a time so perhaps that is a factor. 4 to 6 inch inline with a high quality can on it always seemed to work great for me. Good luck!

No window units

other than a another mitsu mini-split...............your only other option is a chiller when it comes to efficiency in a sealed room. Personally don't like them(too much plumbing IMO), never used one though. Can read about it here:

I would do some solid research on the standalone ac/dehumid units and find one with the best rating/efficiency (dual hose?) and just bite the higher energy cost to run them......IDK, tough call grower

Not a pipe dream. My room is totally sealed and double insulated and as long as it is in the 40's outside, I can stay low to mid 80's with no AC or exhaust. But I can't bank on thataimtaining throughout the grow so I have te AC. But it's load is very light.

This is what I am doing in pieces right now.....

Currently have a 10x10.5 room split into halves flower 10x10 veg 10.5x10. Southern exposure so room temp swings only solution to seal and use CO2 in flower is to seal flower from veg install dual zone mini split Mitsubishi into veg portion of the room, a fan thermoswitch in flower so that when flower hits peak temp air then is circulated out into veg room which remains sealed whereas mini split in veg is keeping veg temps high 70's 80 max. The closer to the flower room max the better less CO2 will disperse into veg and that which does will just enhance veg.

Anywise this other part of the dual zone handles higher BTU coverage for rest of building and its rooms helping to keep the sealed flower veg room in a steady zone to work with rest of structure.

Anywise I am looking to install the dual zone mini split soon before spring hits, no way will I be able to keep environment suitable and run the Onyx leds I plan on adding more off soon. Currently vented out filtered air into the cooler part of the building and am circulating cooler air in from under craw space from closet vented to flower room providing a fresh source of CO2 and I am using a CO2 Mushroom bag suspended above grow currently to help. for CO2 cannot go in till mini split is in place. Not sure it is that much help.

Anywise I am using wall fan to move air and dehumidifier to remove water it adds to the heat of the room and I have to empty every few days. With mini split should be able to have it work less putting off less heat which will as a a good redundant unit should mini split in veg humidity get too high.

Here's pic of first attempt at scrog no more christmas trees with low yields,,, two onyx bloom over a 4x4 section in the flower room split into two sections with entrance in middle from veg area of room.

I love fresh air systems...they are so easy to run and setup. CO2 better be worth it or I'll be back to fresh air in a snap, and just looking at my co2 meter out of curiosity since I forked for it already.

Hard to beat fresh air , It's easier to do IMO and it works.

CO2 can add 15-40% increase in yield...some reports of 100% increase(must have been doing shit wrong before imo).
So if the gain is truly there...30% increase for me is 1/2lb per light extra...sign me up. But is it really...we will see.

 

[DANKSWAG]

easy is as easy does... no pain no gain... it is what it is...come on man!

Alright anywise numbers don't lie but can be manipulated.... bottom line is what you weight baby... for
Weight = $$$ in money not spent on medicine...

So with that being said I am moving to a controlled environment htat I would preferred sealed for privacy concerns for the collective and respect for community so CO2 seems to be worth what the proven potential...

I don't think co2 increase yield by much. Maybe 20% at most. I do think it can improve trichome production. I've seen a big difference. I prefer fresh air exchange. Imo plants do much better over all with fresh air. Plus its easier and cheaper to cool down a room. It's finally cooled down here. As of a few days ago I'm no longer running a/c. I can set the intake back up. I don't bring in fresh air when its too hot. I don't want to.bring in hot air.

 

[medicinehuman]

Luckily mine do good enough with out extra co2. But if I wanted more I might try it, I been known to experiment a little in the past

 

[Rrog]

I'd like to do fresh air, and did "fresh air" in my last place (re-circ with the rest of the basement)

I want to avoid the smells, and if the added CO2 allowed me to deal with heat / humidity easier, then that's cool

Dankswag- I appreciate the detail of your room. Just to clarify, 1 of the 2 mini-split zones is for the veg room, the other zone is the rest of the house, or whatever?

carbon filters, phresh or green gator

 

[Rrog]

Been there and done that with carbon filters. While there great, they're not foolproof. High humidity can reduce efficiency, they can temporarily absorb CO2, and you have to monitor them for replacement. I'll still run one in the veg room, since that's where the main door to the area is and some stink can leak there when I open the door. I may do a double door airlock kind of dealio

green gator sells replacement carbon or if you have access to a kiln you can bake old carbon at 1700 degrees and it will clean it and make it like new.

Where I'm at I have to add humidity so thats not an issue. The filters do make a big difference. of course you need to match cfm's and what not... I'd imagine where you are at your area naturally has high humidity . All those lakes

 

[Rrog]

Ya, I just can't depend on carbon these days.
