Now, the wiki page
Says, for the Irrigation Blueprint
"Replaces sand with dirt, grows grass on top of dirt, causes plants to grow faster, lets sugar cane grow past 3 blocks and rarely spawns water below the Terraformer. Takes 8 EU/t."
In practice, from a test on a test world, the Terraformer is taking all the EU it can get it's hands on, which, in this case, is an MFE, so 128EU/t, not 8 EU/t ... Is the Wiki not up to date or am I doing something wrong?
