I have to ask what is the point of the Hydro then ? If it withers after 5 days AND requires you to manually place a water block, then it has absolutely no use. I have been wondering why they have not been sipping, and now i understand.
If this is correct it needs to be one OR the other, not AND. If it remains the way it is currently there is no reason to use the flower period. It is consuming both the source block to create the mana, and the flower itself because it is passive. Having to manually place a water block is not a passive system. This is no different then a endoflame where you have to feed it. So why does the Hydro wither and the endoflame does not ?
