I grow Earth and Dark ore for me and my lil LS I'm going to grow into a mighty Dynamis LS one day...lol but until then...we're lvlin and farming Tree Saplings
But here is my method of growing Earth and Dark Ores.
we'll start off with the batch i just started.
Moghancments: Gardening
Equip: Workbench, x12 procelin pots, Maple and Oak Table and a Tartaru Desk.
Planted: 10-19-2006
1st Crystal Fed: Earthx6 Darkx6 on 10-26-2006
2nd Crystal Fed: Earthx6 Darkx6 on 11-05-2006 could have fed on 11-2-06 but wasn't able to get to my account due to vacation.
Harvest[b]: Edit 11-12-2006 Picked x4 Dark ore out of 4 pots. Picked x24 Persikos out of 2 pots
picked x3 Earth ore out of 3 pots. Picked x36 Kitron out of 3 pots.
New items harvested: Persikos and Kitron (Ingredients for Cursed soup and Persikos au Lait)
Fairy sell stats: 400k Dark and Earth ore 32k Persikos (stack) 2k Kitron (stack)
Gains and Failure: Gains...obviously the ore but Failures, all i've seen from my batches are tree cuttings. I'm not sure if this is the other thing you can grow like this but all i can report so far is tree cuttings whcih you can grow into saplings and rinse and repeat with earth crystals and get saplings.
Note: I've noticed ores will grow no matter what element is flowing thru your moghouse. I've heard a lot of people say you need the highest element lvl flowing thru your house to be able to grow ore effectively. i think its just depending on your batch really. From my tests if you plan on growing 12-24 or more you should have the 2nd or 3rd element lvl flowing thru your MH and you'll have a good harvest of Ores. Feel free to add info here as well. This is the method I've used for 3 batches now and i've had vast harvests. Feel free to use it as well and all thanks can go to yourself for growing the ore succesfully.
