Yeah, but now there's no reason to bother with passive flowers at all (past the first few), especially not hydro's. (since they need mana petals and still wilt)
The rannuncarpus (block placer flower) is capable of placing down flowers now however, so I guess you could use that to replace things if you really wanted. (but again, not floating hydro stacks)
Good timing though...I just finished designing a high output, fully automated Entropinnyum setup. Can process 2 TNT per second with an auto shutoff based on how full the mana pool is. Automagy, botania, vanilla, and the crafters from enhanced inventories. (supplied from essence of creeper/fire/earth)
It'd be a hell of a lot less complicated if I didn't want it to fire off 2 tnt per second aimed at one recessive pool...
