When I apply one sheet of drywall to another I use core board screws. They are designed with this in mind. Use your regular screws 1 1/4 inch to apply the first layer and the the core board screws to apply the second.

First thing that comes in mind is a thermostat set to highest value, that triggers a relay connected to panel/main electricity source

thermostat 15$
relay 5-10$

This is a great thread don't know why I didn't see it before. I am also a master carpenter and general contractor. I have been building houses and commercial buildings for a long time. Every year fire saftey gets more and more strict. When I design a room I always think of every thing you had mentioned. The only few differences in the rooms I design is, 1. I use a commercial corrador door. These doors have a fire rating of 90 min. (I get these for free during a demo of a suite in a commercial building.) Next I use 5/8 sheet rock on all walls and lid. This gives you a fire rating of 30 min. Last but not least, I use fire rated ply wood to hang all my ballast and equipment. This way if there is a short from this equipment there is no way for a fire to start. 3/4 ply will work as well, but to be safe the fire rated will not burn. Hope this helps somebody in the future, Peace and Love.

my grow is in the basement and all the electrical and plumbing are exposed. My growroom is a former woodworking area and the former owner installed sprinklers. I have one inside the grow, and one right outside near the sub panel and ballasts.

Worked out good for me.

I think if you have access to the plumbing, installing the sprinklers is easy. Looks like they just tapped into the cold water lines and soldered in the sprinklers.

a "pigtail" is a power strip with multiple plugins. look for one that says "circuit breaker" or surge suppressor" on it.

great info, thanks so much. now that i feel i have my perfect setup i need to focus on saftey precautions like these. I will be fireproofing everything as u outlined, and will also setup a remote monitoring system outside of the grow using 2 panasonic bl-c131a units (plug and play/ wireless, $250 on amazon).

This thread got me thinking. Removing all the combustibles sounds like good advice. I got rid of the styrofoam and mylar I was using to reflect light. I picked up some aluminum coil in the roofing area of the store for $5 for 6" x 10'. I did an experiment where I put some mylar on the aluminum and lit it with a lighter. The only part that burned was the part that was protruding past the aluminum. I made much safer reflectors by gluing the mylar to the aluminum. www.cheaphydroponics.com has high temperature shutdown & light ON delays for a reasonable price.

I like this thread, fire safety is should be up there with odor control.

Expecially if you have a family, you owe it to them to make this as safe as possible.

I use 2 arc fault breakers that feed 2 seperate outlets into my room, I had to install a junction box off my main breaker because no one sells arc fault breakers for my main breaker box.

I don't use GFI outlets, I don't do hydro, and do not keep water in the same room that the pants grow in so I never thought it would be a benefit.

Is there? I don't mind if I actually am buying more safety, I figured the arc fault was the most important thing.

I also use connected to my balast/light the 15 minute timer so that is prevents hot starts on my light if there are ever interupptions to power during storms, etc.., and it is set to anything over 90 F it cuts power to the balast/light.

I also use a smoke detector that is hard wired to a baby monitor based which then is connected to a monitor in our bedroom so if there ever is a fire during the night I will be woken up from the monitor going off. (And there is an estenguisher in the basement)

After reading this thread I am thinking, even with all my effort I still have issues because fire if it did happen spreads so damn quick and likes to go up.

I have a baement with a room I framed and put up I grow in. Since it is in the basement there is unfinished cealing above which is basically the subfloor for the floor above the basement. (Which is 2x4's for the framing and plywood for the above floor) That is a danger I can see now. If the light did burn for some reason, the heat going up would probably ignite the plywood very quickly.

I was thinking of now building yet another room within this room that would just be a drywall box with the light on pulleyes, plants and a tube with the exhaust being pulled from outside of this drywall grow box.

I was wondering though, when people say sheetrock, do you mean standard drywall?

If I frame a box out in my current grow room and then drywall it and it would then look like a wardrobe cabinet, what would be recomended to put on the front of this drywall cabinet for access that is more safe from fire, but still pretty good at not letting light in or out and is easy to open to tend to the plants in the drywall box?

Thanks in advance for any tips.
