Mint Chunks and Weed Respawn Timers? in Grounded: General Discussion (NO SPOILERS) Posted August 1, 2020 1 hour ago, flea said: You've actually had weeds respawn? How many days did it take? Currently on probably 14 days without respawn, probably about 5-6 days after chopping the root also. this is many times slower than actual dandelions grow.
