This was in a test world, and was setup to help someone out with easy crafting of the drop of luck/redstone soup.@Rokuma, could we see the rest of your setup?

FTBWiki Altar Page (useful for figuring out what to add for more power)
I don't have any images of the last setup, but it would have been somewhat difficult to show as it was on multiple floors. I'm currently starting a new world due to corruption so I can't grab any images.
My top level (actually ground level) was a small forest with tall grass and various plants for power. At the maximum 32 block distance out was my primary ritual circle.
Second level was my farm level, additionally benefiting the altar for power, down a third layer was where my cauldron/kettle/distillery/spinning wheel area. An obsidian room next to that was my cauldron based demon summoning spot. (Little tip, if you're invisible demons don't attack you making trading easy. Botania's Tainted Blood Necklace can be enchanted with "cloaking" to do so, just remove armor and make sure you have mana available.)
EDIT: Basically, power wise, anything with the same ID# count as the same ignoring meta/damage value.
Think of the altar as a generator/battery combo, with wireless transmission to any "machines" of the mod.
