I would like to make an addition. Growing Ranarrs can be incredibly profitable using 5 patches but I generally use just 1. The one in the Troll Stronghold will never get diseased. The only way this works is if you cant get on to play very often. (Perfect during school/work). Simply take a dueling ring, 2law 2 fire runes, 5 seeds. Once you teleport to the stronghold run up and get your equipment from the leprechaun. Now you simply weed, super compost, plant, and log out. Every 90 minutes log in and harvest, super compost, and plant again. If generally takes 2 minutes for the whole process. Usually after 4 seeds youll have to teleport and bank your ranarr. Using this method since your not playing anyway you can easily make over 600k per hour just by logging in when you get the chance!
