Artifacts generally recharge very slowly (sometimes only in sunlight, I think) OR fairly quickly but inflict pain or 1 point of damage to every body part.
That particular artifacts sounds like it’s doing a flashbang effect - bright and loud (look at the sound when you do it). Useful to draw zombies away from something… but then, they’re coming TO YOU, so be ready (or ready to run).
Many generated artifacts are really lousy. I recently found one that passively emitted smoke all the time (one of the least bad bad things there is, actually), and for active, covered the area in blood (THE most useless thing that any artifact does).

Is there a way to convert underground floors in a lab into farm-able land?

Do underground farms (e.g. basements) need light to grow crops?[/quote]

It appears to be temperature based (there are times in the fall when you can plant during the day but get the “too cold” message at night, for instance), so maybe, if you get the area warm enough? Never tried.

YES! All you need is a Triffid queen, an artifact that does plant growth, or (if you are playing with the Arcana mod) a scroll of growth. Any of those will convert the tiles they affect to dirt (I’ve heard people have used that to extend the UPPER levels of two story buildings… heh). Also, roof collapses sometimes make the floor dirt, but that has varied with different builds and other development, and I never bothered with it enough to discover a pattern (and I haven’t tried recently).

Never tried, but people have claimed to have grown crops underground, so that answer seems to be NO.
