I couldn't find any post about this so im wondering if it has been covered yet. I know you can simply not feed your plant when you harvest the 7th resource and are waiting for the 8th to generate (since one day of not feeding wont kill the plant.) I'm also pretty sure that I've had plants that yielded their resources for two days without feeding. I'm not sure if it was just the RNG on my side or not though. Has anybody looked into starving their plants to save a bit on potions? If not i can experiment around with this but it'll take about a week for my results to show. EDIT: I did find a reference to starving it one day in 1.14.13 of the FAQ. Not sure if 2 or more is feasible though.
