Rockwool panelling?! WTF is that?

How about attaching the smoke alarm to a CO2 bottle that could purge itself (20lbs all at once) into the grow area if there's a fire? Would that work?

Only problem with that is that the super high levels of CO2 could cause an asphyxiation hazard if the space is small enough unless you had a fan to vent it a few minutes after discharging the tank. That would really suck if you were sleeping in the same house and it went off since you'd never wake up...

I went to Lowes and Home Depot to purchase the arc fault breakers. They only have ones up to 20 amps which will not work for a 240 30 amp circuit of which I have one...all the other circuits are on the arc faults. Also, I didn't see any of the ones with the "pigtail" although the arcfault breakers have one incorporated into them and is part of how they work. I'm more worried about the propane C02 generator which can get really hot. I'm installing a piece of fireboard (used for wood burning stoves) above it. I also have a high temp cut off from CAP systems and set it for 100 F. If a fire did break out, everything would shut down, fans, lights, all. Grainger also has fire dampers for ventilation ducts. If a fire breaks out, these quickley close from the heat and starve the fire (at least block the ducting air flow). Having new ballasts, fans, etc...probably cuts down on these items causing problems if they are made by reputable companies like Sunlight Systems. Can also install in house detector and when away from the home can use HOBO's (dataloggers) which have a phone dialer and will call you when a sensor is tripped. You can set the alarm temp and when reached it will call you. You can also use this type of system for security and water leaks. Sensors are available for all and having the dialer call you instead of a monitoring company may save you and your grow. I do like the fire extinguishing system but there are also other systems that may be cheaper such as the regular sprinkler system discussed in earlier post. I'd be interested in getting more info on how to put that together since it's undoubtedly much cheaper than the auto fire extinguisher (1000 for 900 cubic feet). Water is much cheaper and with electrical cut offs would work great.

Excellent post

This should be a stickie in the Growroom Designs & Equipment, or general Growers Forums.

i agree.

Any one have a diy to make a high temp shut down?
I saw CAP has a high temp shut down that aslo included a 15min delay, so your light didn't start up to soon. Darn thing is $150. If it is like most of my other DIY project's. I'll prolly have $149 tied up trying to make one.

Very informative helpful thread G. Potter!!!
I have heard of 5/8 board that is up to fire code, I have heard of some doubling this up, just get daggers, lol
I mean long ass screws, I reccomend 2 inch screws, you would have a little over a half inch biting into the wood....

Now if you go one layer, which would be fine for CABS then 1 1/4 inch screws will work fine..


To those with hydro rooms I did a lil research on mold proof board...
If available this would be best in hydro grow rooms, as well as in all since mold is an issue we try to eliminate all together if possible, mold is the enemy!!
Well one of them anyway, lol

ToughRock® Fireguard® Moisture-Guard
Available in 1/2" and 5/8" with fire-resistant Type X core.

That can be found here..

Scroll to the bottom and work your way up, you will find it faster..

A lil note, to those worrying about sound, they do make a 1/4" Sound Deadening Board that can be used under the 5/8" board..

[[Use with 1/2" or 5/8" ToughRock Fireguard to meet requirements for sound and fire resistance.]]

Here is the 5/8" Type X Gypsum Wallboard Standards, Testing, and Certification fire safety information...

I imaging that the ToughRock® Fireguard® Moisture-Guard can be painted, but I would use Foylon,if you can find it... it is heat and flame ressitant
It's manufacturer discontinued it, but it is still available from some other places..

It is easy to clean, easy to install, and lasts for many years....
It will reflect about 95% of the light.. and approximately 85% of the heat energy, so a good ventilation system should be used in conjunction with folyon.

A recommended method to attach Foylon to the walls would be using Velcro, as it makes taking it down for cleaning much easier..

Hope that helps a little, happy, safe growing everybody!!!


ish I had some C3 anti-detection film...
