Hey CJ, when you have time, im wondering if you have any pointers in regards to my set up. Currently in between runs at a new location.
First Run
- 5 ton heat pump/water cooled chiller in a "lung room" cooling two rooms that are flip-flopping every 12 hours
-The AC had a make shift hood-i think they are called- with 12 inch ducting leading to valves that flip flop with the lights, putting the cool air in the appropriate room
-The big room is roughly 14x14 and there were 15 vert 1000 watt bulbs (seemed to keep temps nicely around 78)
-The second room is 10x12 and had 12 vert 1000 watt bulbs and the temps were the same
-Both rooms had 12 inch exhausting into the lung room
-all rooms are sealed (not perfectly)
-NO CO2

Current plan for next run
-Same 5 ton chiller, new (proper) hood with 2 extra 12 inch take offs one to each room, plus the existing 12 inch take off into the 12 inch flip flop ducts
-2 12 inch exhausts in each room to help bring out the heat straight into the lung room (pulling though big can filters)
-hoping to cool 16 lights in each room to have an even 32 light flip
-Burning CO2

Just to clarify, when the lights are on in room 1, the ac has 2 12 inch ducts pushing cool air into the room, and the room has 2 12 inch ducts pulling through a can fan each into the lung room so the room continuously exchanges air.

So this is the plan, last run the ac would ice up if we tried to drop temps below 75, we suspect this was because of lack of return air combined with too small ducting from the AC.

I realize this is asking a shit load out of this ac, but it seemed to do fine with the 15 lights last time, and was running I would say 45% of the time- so we will see. If either room cannot be cooled properly, we can easily turn lights off to adjust. Naturally, we want as much light as possible to take full advantage of our space limitations.

I am wondering if anyone has had any experience with ozone poisioning of plants ... I put a industrial strength ozone generator in my flower room and came back the next day to find it had curled all the fan leaves ... I was horrified at what a rookie move I pulled .. I should have done more research about ozone ... I knew it was harmful to humans and animals in concentrated amounts but didn't know it would kill plants as well .. Does anyone know if the plants can turn around and finish normally ??????????????????????

I would say your plan for a new run looks good except I would do 2- 14 inch ducts for cooling and exhaust back to lung room.

Hey brother... hope all is good. Got a question for you... is the condensation run off useable for my humidifier?

I don't know if they'll recover. I'm pretty sure ozone is O3 and what your plants need is CO2. Ozone in a flower room will only remove the smell from your buds. I know its a little late, but if you want to remove the smell with ozone, you need to do it outside the room on its way out. Or else all you'll do is remove the smell from your plants. I'm sure there's plenty of info out there. I've never had any plants come back from any of my stupid mistakes. But it's kind of hard to tell without pictures.

Hey Cannibis John,
You guided me on a 10,000 btu Friedrich which kicks tail, you also advised me if I didn't have the extra funds frigidaire is a good brand at a lower price. I have a couple rooms one with the friedrich and the others with a frigidaire, but i noticed the frigidaire leaks allot of water even more so when the temps outside are hot ? It has started to eat at the dry wall. The friedrich doesn't leak any water? Is this an issue because of the cheaper unit or is there other factors at work?
I'm willing to buy another Friedrich if that will fix the issue?

If it started brand new then return it. If it is older than check to see if drain is clear. Drain should be outside. Is it freezing up or cooling just fine? If it is freezing up than get it serviced. I assume itis still under warranty.

THX for the reply sir,
No the units are about 8months old. Now that I think of it I have a new frigidaire in a veg room and it doesn't leak. The units that are leaking are all older than one year old. The Friedrich is going on a year and a half and no leaks. The water does drip from the back grill of the frigidaire's, its not falling in the room but i have it mounted low, close to the ground so a puddle gathers and soaks the drywall. thinking of mounting it higher and catching it in a bucket like my other rooms. I appreciate all you time and wisdom.

Do that.

can you help me interpret this chart from can fan?I am not sure what "wg" stands for?
Is it "static pressure" or inches of ducting or something like that?

Performance Data
|--------------------------- in. wg -----------------------------------------------------------|
-----------0" -- .125" .25" .375" -.5"* .75"* 1.0" -1.25" 1.5"
CFM 8" - 667 --650 -630 -610 -585 -520 --420 - 150 -100
CFM 12" 1708 1680 1655 1630 1595 1530 1460 1380 1300

Looikng to make a light trap/stop light leaks from a 12' max fan with the least amount of cfm loss possible..

The fan is between two flower rooms, sharing an ac.

I looked into dust shrooms but they are pretty expensive, but that might be the best route.
I would definitely need two, because I looked at one and it didn't quite do the trick...


Dark room vents seem like they would cut down on flow quite a bit....
I have gotten the temps to level out, but I have a good amount of light leaking between the two rooms. .

It is inches of back pressure on duct. More duct on it the more fricition losses so less air movement. How do you plan on making the light trap? My suggestion would be hard pipe and 90 elbows. Avoid doing it with flex duct. Also oversize the light trap to 14 inch. Should work better that way. Good luck.

Hey CJ,

I have a 5k btu and a 7 k btu AC both window units. Both old. One from early 90's (5k) and one from the 80's (7k)

Both of them have sat but still run. The run switch on both of them get stuck leaving either unit on or off.

I would like to connect them both to a controller allowing them to cool to a degree instead of a cool cooler basis.

Have looked at a few conversions although I have not even checked my units line voltage that it runs to the run switch.

What would I need to setup a controller to control both my wall units together using a single thermostat. I suppose I could use two Seperate and achieve the same thing but any suggestions appreciated

Most likely if they are that old the voltage at the switch will be line voltage. Make sure before you do anything. I need to know before I tell you anything. Also what type of controller are you thinking about using? Or are you asking my opinion on the controller?

Yeah, They are old as balls and im almost 100% positive they are line voltage. that being said they would be 110/115.

Im looking for options on controllers, I would not even be apposed to setting up some sort of low voltage circuit and using a digital wall thermostat.


Thanks

You can get a 2 stage thermostat, 2 contactors, 2 outlets, and a 24 volt transformer. Install it in an electrical box. The stat energizes the contactors one at a time which power up the plugs. If you don't understand this then don't attempt it and buy a controller at hydro store or online. Be vey careful if you attempt this.


Thanks
