My weeding practice in raised beds is as follows: do a big weeding before planting things, leave things the fuck alone until what you planted is big enough to not injure or mistake for a weed, do another big weeding, try and keep on top of it so it never gets out of control until the planted items take over and wedding isn't really required, just pull the things that are flowering.
Even with the above I still try to have a light hand and not go tilling or pulling everything up and disturbing the soil.
Today I pulled up what looks like the fruiting body of dead man finger fungus. I probably killed those ones but because I caught it so early I am able to notice and be careful around the other fruiting body I found. Hopefully I'll be rewarded but a show put on by this creepy friend!
You are more advanced than us! We have just a large planter full of rocks with enough water for a solar powered pump to keep it circulating. It stops at night but generally keeps it pretty fresh.
We just top it up when the level gets too low for the pump, and empty it in the winter (which lets the rocks dry off and clean up over winter too).
