Not by default, but you can use MineTweaker to merge/mirror the ore dictionary entries so Growthcraft stuff will work in Pam's recipes.
I'm delighted that we have a fix for the fluid registry thing. Thanks, shortybsd! (And what happened to the 'thank' button, anyway? I can't find it anymore).
Next question: are you or someone taking over Growthcraft maintenance and development?
You're very welcome and I am glad I could be of some help. He isn't passing it down to anyone far as I know. I seen some guys that were wanting to add a bunch of cool things. Source was only posted so one of us could write a fix so it is fully working in the newer forge builds. If anyone were to get rights I would like to see how GrothHammerPick does with it. I would offer to take over the project but due to work and working at home I wouldn't have the time. Also you probably wouldn't want me on the project no matter the content I added as I would never port it to MC 1.8.x lol I am sticking with 1.7.10.
As for a thank button, the like button works good 
even commenting shows great respect and is much appreciated.

I actually brew my own beer and wine and offered to help out with the Mod. Now that he has released the source, I'll be adding Hop and Grape strains. So you'll soon be able to make stouts, porters, IPA's ,etc.
