Am running a set of Garden Cloches to make two separate Pam's Harvestcraft foods - Veggie Stirfry, and Roasted Root Veggie Medley. However, both carrots and rice lag severely behind the overall growth speed of all the other Pam's veggies. my spice leaf, turnips, eggplant, bell peppers, noo problem. But, carrots and rice are an absolute bottleneck, to the point where all the other cloches are full of their respective veggies, and the analog crafters are just waiting on the carrots (and/or rice) to complete the next food item.

Using default FTB Revelation modpack, so ImmersiveEngineering-0.12-80-core.jar ImmersiveEngineering-0.12-80.jar are what is currently running.

can you check if that is controlled by a config/minetweaker edit?

I checked in the FTBRevelation/minecraft/tscripts/(00_recipe_changes|01_unification).zs files, but didn't find anything relevant to either carrots, or the garden cloche. BTW it's now CraftTweaker, as the official continuation of minetweaker 3.

I have also since the original report, updated to Revelation 2.1.0 and started a brand new world (for the worldgen on thaumcraft, twilight forest, etc) and recently just set up a similar setup as before, and am still experiencing the problem wherein carrots take an extraordinarily longer time to grow than the rest of the harvestcraft plants.

currently at ImmersiveEngineering-0.12-82.jar and Pam's\ HarvestCraft\ 1.12.2u.jar

I can include screenshots of the setup if desired.
