Experienced Electrician! Here to Answer Any and All Growroom Electrical Questions

tell him you are putting in a spa for when all the girls come over for party's - the spa is rated at 5kw

I meant do i Say i need a new sub panel put in or breaker or what? like i said i have no knowledge in the electrical field.

go with the subpanel for a spa idea. tell him you want to get the electrical there and add the spa later.

Ok so heres my electrical question, I just moved into a new house and i want my master bedroom to be able to handle up to about 5k watts, not saying i will be using them all i just would rather have more than less. What would i tell an electrician when I call him? What would i say to sound more professional, Honestly have no experience or knowledge in the electrical field my uncle wired my last two rooms RIP. Just don't want to sound to conspicuous or anything. Thanks in advance for the input
Im in San Diego, California by the way.

not knocking anyone else's ideas put let's get serious.

tell the electrician that you need a 60amp sub panel with a main breaker in the room. tell him you are installing a large saltwater reef tank. large fish tanks use pumps, lights, filters, and chillers. they consume a lot of electricity and are something very common that you would find in a master bedroom. then when you know where everything is going to be setup you can do some basic wiring yourself or have the electrician do it before you put any equipment in there.

60amps will be plenty to run 5k watts, a/c, fans, etc..

hi there bricktown73, im from the uk, the electric company around here have just put the new SMART METER at my home. my question is ,is there anything that can be done so i can keep growing??
is there any way around this?

So it took me awhile... But I finally read through enough of this thread to answer my question . More importantly I understand it. I mean I really, really understand it now. I was able to run my 8/3 line from my main load center to a sub panel in my garage. With no real prior electrical experience I was able to grasp the concept and incorporate it safely into my room. The sub panel is a (4 )space load center upgradable to an (* space. I was also able to run an MLC-8xt from that sub load center off of a 40amp 2pole breaker. I know that the MLC is rated for 50amp but at no time will I ever come close to pulling that much draw. i was also able to open up the MLC-8xt and spliced into the 120 "hot' timer trigger cord, which I connected back to the timer and to the bottom relay. Giving me (4) outlets now run off the timer "top relay" and (4) outlets that stay live "bottom relay". This will allow me to add a 240 ac in the future without running any more outlets.

Total cost was around $300.. But I could have slashed that down significantly. I did not know that I could have gone to my local ma and pop electric shop to just ask for a specific amount of romex and pulled the rookie move of buying like 100+ feet of it from homo de pot. If only I had read a few more pages

I would just like to say thank you for all of the electricians and electrical engineers who contributed to this thread and making sure people are doing things safe or getting professional help.


TO ALL MY SPARKEYS!!! I FN LOVE YOU GUYS.

My garage is so fucking bright... I SEE THE LIGHT BITCHES!!!

Hey Bricktown73,

I am a newbie to indoor growing and just got a tad question about ballasts. Currently running two 400 watts grow lights in a 6.5' x 6.5' x 6.5 Grow tent and will be upgrading to two 600 watt Grow Light Kits and just needed to know if it was possible to hook-up both systems on either a 20 amp or 30 amp breaker (with the 400's, no problems so far with power issues. With that, thinking of plugging two smaller fans (rated 1.0 amps), would that be pushing it?

Thanks and awesome set-up with your electrical stuff!

1200 watts of light is about 10amps at 120v. plus 2 amps of fans. you are well below the limit. go for it.

i have a titan helios 7 light controler that runs of off 240 and i have my 240 supply comming from my dryer outlet,but my supply only has 3 wires on it and the titan controler has 4 spots to install wire starting from left to right ,it says ground,hot,neutral,hot. so wher do i put my 3 wires i have coming from my 240 supply? please help

Just a thought here ruby, but you might want to start a new thread for your question.
That way, it will help others find it if they have a similar question in the future and it might get more views than tagging onto the end of a resolved question.

Sounds like the controller wants a neutral and you have none at the receptacle. Does the controller have 120v receptacles or the timer need 120v? Maybe you don't need the neutral?

no 120 volt at all,it takes a 240 supply and gives 240 to the ballasts

Then wire the two hots and the ground.

I have a question about powering up a new grow op..
I have a steel building with 200 amp service inbound. I have 110,220,and440. 3 phase I've been told. And a stinger leg that seems to burn shit up when there's a breaker in those spaces.So I just dont use them..
My question is how much of the 200 can I put in the grow,and what sub panel I'd need.
I'm hoping for about 150amp w/20 spaces.
The sub panel will be 80 feet total from the main--what size wire?
Thanks to all that can assist

The phase-to-neutral voltage of two of the phases will be half of the phase-to-phase voltage. The remaining phase-to-neutral voltage will be √3 times half the phase-to-phase voltage, the transformer is connected such that the 'B' phase is the 'high' leg.

You have any pics? The 440 panel is probably over 40 years old. 440 is pretty obsolete, all 460/480 now.

Sounds like a single transformer, delta with a bitch (high) leg. The high leg will have more voltage potential. Also the center tapped neutral is usually limited to 5% of kva.

Sup fellow growers!

I am currently hooking up a new system and bought a electrical panel for my six lamps.
All the wiring was already done exept the cabel from the outlet.

The only fuse that did not have wiring was the "General" and it was wired to the one next to it.
Am I right to just connect a wire from my main circuit to this one ?

On the photos is the one up in the left corner.
I plan to run around 5-6000watt on this panel.

Awesome Scoob, appreciate the feedback.

Hey bricktown, im planning on growing in an attic. Instead of running an extension cord from a socket in the house, I thought about a socket in the attic.

After reading a bit I understand the socket would have to be wired into the main breaker for the house?
Any chance you could walk me through doing this? Or will to be to difficult?
The main breaker is on the ground floor of the house

do you have any other sub panels in the house? sometimes on a 2 story house you'll see a 200amp main panel on the first floor and a 100amp sub panel on the 2nd floor or sometimes in the basement.

i could walk you through this pretty easily. first real question is how much light are you going to be using?

As far as I know the only panel is on the ground floor next to the electricity meter.
I only want to run 300/400w of cfl for veg. And a 600w hps for flower, and the necessary fans for each tent.
Im no electrician so I don't know if thats a lot. My main concern really is, if someone saw a cord coming from the roof into say,a bedroom socket. Well it goes without saying that it would arouse suspicion
