I tried something really fun - combining MFR with XYcraft - especially soil blocks from xycraft.
I made 5x5 tree farm on 8 blocks of SOIL on each spot (a lot of crafting), upgrades for planter & harvester - 4 blocks.
Trees grow like crazy and i don't know what to do with the wood i get. I also have Steve's Cart 2 farm.
Big minus from MFR tree farm is it produces small amount of saplings - about 6:1, 7:1 (logs:saplings) - which i need to make biofuel for liquid boiler.
I use oak saplings - maybe i should change them for different one ?
Does SC2 makes more saplings than MFR tree farm ? I mean in versions of mods for 1.4.7 ?
And for 1.5.2 SC2 galgadorian wood cutter (1.4.7 normal cutter) makes the same amount of saplings or more ?
The thing about MFR farms is that they tend to grow trees overlapping each other, so you get less saplings. Try only having a single stack of xychorium soil over the planter. Or put cobble in between to space out the trees a bit.
