Only negative thing I've found about spiders is when the spin their web on your plant, sometimes they close leaves up with their silk. So not a super negative thing, but something you don't want happening alot.

Very true. I actually found a few spiders on my plants so far this year. And I let them go, came back and checked on the plants a few days later. And they had used a whole leaf, used there silk to hold it together, and wrapped it up over top of each other so that the leaf looked like a hot dog bun (if you can picture that) and well it totally killed the leaf...so just be careful and always inspect your plants !
