Yes, but we can get it down to 1 Tick Max. Doesn't that sound great?Actually, it wouldn't matter that much, if at all. My system was, in fact, total overkill as-is; the crops are growing in a maximum of 2 ticks, more often than not 1. It's really the collection and planting that are the two roadblocks from my brief experience.
Or I could just add 30 more Time Torches and enable them to work on machines. That would work too.
