There are many very nice, well filtered, well regulated power supplies
on the market. I see NO REASON for using anything other than the
station power supply to power all accessories. As to plant lights,
use a separate power supply and not the piece of junk supplied with them.
I have and use two switch mode supplies for all of my station
equipment. That encompasses two 100 watt transceivers an a 150 watt VHF
amp. From 160M - 2M I have ZERO noise from either or from both of
these supplies. Frequently I am running two radios on 2 different
bands at the same time.
Jim, K9YC, has very strong merits in that each and every piece of
equipment MUST be bonded to a single common point. I use the station
power supply for my single common bonding point. I DO NOT use an
external dedicated ground as it would be 35 ft in length and serve as an
antenna to pick up noise. After all, that is 1/4 wavelength on 40M.
As to what's in the neighborhood, that's another issue out of my control.

It gets worse with all the new gadgets and LED lighting. I just
installed new plant lights, LEDs, and the racket from the wall warts is
terrible. I shut them off when operating, or not interested in lighting
up the plants. Terrible view of the noise on K4 graphic display.
