Cropmatron: Unecessary Waste?

I decided to leave my cropmatron and booze barrels going for a few hours and then come back and do some gardening. What do I find when I come back? My matrons both of them are completely empty. 6 stacks of fert 6 hydration cells all gone. Note: I had not changed anything to the crops before going afk. Now, I put it to you. If we have things like booze barrels which need vast amounts of time to ferment and cropmatrons which just keep pumping resources into plants that are fully grown. Is this massively wasteful?

So, what you're saying is a fullgrown plant that hasn't been harvested should need hydration and fertilizer endlessly and we need to babysit the cropmatron to make sure its not using up our supply of fert and cells? Also, when a cropmatron is supplying nothing to no plants but is hooked up to a batbox it just drains them anyway. I'd think the cropmatron would help a plant grow to full and then stop pumping things into it and when that spot became harvested or planted it would say aha! a new plant and give it supply from its storage etc. Unless, gains and seed drops are affected by current store of hydration and nutrients I don't see the point of endlessly pumping its storage into everything.

Even if nutrition and hydration do affect drops and gains it doesn't mean I want them to be at 100% constantly. I don't ideally always want to harvest the plant so what the current setup means is I need to figure out precisely how much fert and hydration cells I need to grow them fully and even then I never know when the plant's hydration and nutrition levels at even at 100% we have no means of knowing that just the assurance from the cropmatron as it throws resources out.

Perhaps modes?

Harvest Mode: maintains 100% of everything until you shut that mode off and shows you somehow on the box when its ideal harvest conditions.
Fully Grown mode: only supplies resources until the plant is fully grown and then focuses on other growing plants.

as examples

Whether he means one solar panel for both or two it doesn't matter. The cropmatron does indeed act like an EU sink and just keeps taking EU regardless of what its doing. It doesn't reach a state of "I'm done for now" ever.
