If you google, you'll easily end up on the IC2 forum with the crop thread directly. I would try and give you the link but in my crop study during the 2 months period where i experimented a lots with them, i ended up with similar info over different threads.I'm looking for a viable way to produce uua. I've been using conduit binder, but despite the high scrap: input ratio, the non renewable nature of the clay is a problem. What are you guys using for uua?
On a related note, is there a guide to ic2/gt crops? How difficult is it to get the uua berries?
Edit: as for UUA berry, they grow decently fast. Somewhat on a similar way to oilberry i'd say.
