I'd check with the city BEFORE contacting the grower.

Because if you contact him first and have no results, then go to the city and the city shuts him down and he looses his income, guess who he will possibly get even with?

Whereas if the city does it first he doesn't know anything about you.

I'll check that out, and thank you.  I will keep that as a backup plan in the event the person is non-cooperative.

I want to handle this in as friendly manor as possible, as opposed to threats.  But-- if the person stubborns up, that will change my approach.  I simply will not give up my hobby.

So far I have never had to request an FCC letter for a grower. The problem here in Eugene has been the non growers!

One person sheet rocked in a power supply, (outlet and all), for one of those cheap halogen under counter lights for the new Bar he built.

He then claimed he could not fix the problem because he could not get to the wall wart.  That got a request sent to the FCC for a letter by me, and when the letter came to him, the problem got fixed.  It was giving me 40 over 9 RFI on 80, 40, and 30 Meters.

Fortunately the growers here are all pretty laid back here... Hopefully this new one will be as well.  I do however like to have my ducks in a row first though, so thank you again for that tip.

73s and thanks,

You can likely get the city to shut the whole thing down as commercial grow operations are generally not permitted in residential areas. Call your City's local zoning department.

    Thanks to all for the education on pot lighting!  :)

    I will be handing the grower the packet sometime this week...

    Hopefully the grower will proceed in the spirit of the handout,
    which is friendly, firm, but not demanding.  If you are interested,
    the full color handout in all it's beauty is located at:


    at the bottom in the links section.  The ARRL has a fillable form of
    the same text at:


    but it is not as pretty as mine!  :)

    I am developing a handout that can be given to all the pot shops in
    the area, in hopes they will pass to their growers explaining what
    RFI is and why they want it gone...  I suspect once the growers
    realize it takes about 10 minutes to locate them, they will want to
    get on the band wagon for quietness...

    I need to get it developed, then have a lawyer review it for
    liability issues, then redo it until the lawyer is happy... Once
    that is done, I will post it on line.

    73s and thanks,

              From what have observed, the lights are on continually for
             two weeks and then a 12 hours on / 12  hours off until
        harvest which
             can take a number of months.  Depending on the setup, the
        lights are
             off for a week or so while a new crop is planted, and then
        the cycle
             repeats.  To get the latest, just google cannabis grow
        cycle.  See:

                 Can someone refresh my memory here...  I believe there is a
                 cycle of light timing pot growers use on something like
        a 12 or
                 13 weeks period where they go from 18 hours of light to
        12 hours
                 of light...  Does someone know what this cycle is, and why?

                 I ask because my RFI has taken a turn for the worse, 12
                 after it started...

                 Yesterday, it changed from a 12:45 AM start time and a
        6:45 PM
                 end time, to a 6:45 PM  to 12:45 PM the next day end
        time.  This
                 followed a few days of no RFI.  I suspect harvest time
        is upon
                 the grower causing RFI, and I want to avoid handing him his
                 "Welcome" packet during harvest as there will probably
        be lots
                 of people there...
