You basically want to plant today what's gonna be high tomorrow. On my server wood / grapes / avocados / peanuts sell well, but it really depends of your AH cluster, it requires some flair, that's why people playing with AH are so secretive. Also unprotected farming (like planting forests in hidden places) allows you to sell a lot more volumes than just 8x8 + 16x16 farms with Thatched House. Are you having a guild effort regarding lvl44 crafted gear ? Because it requires a shitload of materials from different professions and most people don't understand how crafting works beyond lvl44 (Conqueror Tier). Right now without crafting the "best" gear is Hasla / Karkasse quest gear + Hasla weapons. And believe me you'll need people with nice armor gear soon because farming T1 Hasla weapons is pretty fast and dumb compared to how much costs a full lvl44 gear.
