Greenhouses and sprinklers?

I was working on my sim's greenhouse last night, and it says the plants are sheltered when you take your mouse and hover over the plants. As far as cutting down watering time, I can't really say for sure with the sprinkler, but I can say that my sim is a level 10 in gardening, and when she waters the plants she does several at a time. I'm not sure which skill level that will start at.

Thanks @LaBlue0314! It sounds like it's a good idea to have a greenhouse. And my sim is level 10 gardening too, so I'm not sure how much time the sprinkler will save.

Sprinklers can't be placed inside a greenhouse -- they can only be used outside. They cover a 3x3 area, but I think they can be upgraded to cover a larger area so you don't need as many.

I've decided I'm only going to keep the flowers and herbalism plants inside the greenhouse, while I do the fruits/vegetable/herbs (and trees) outside. Found a really nice build where I'm going to move my O'Dourke family; it had a "garage" but I'm not a fan of the fake cars so I converted that to a greenhouse with the glass roof and put in a few of the 2x2 planter boxes -- that should be plenty for my flower/herbalism plants.
