Agriculture:Feritilizers:Giant Reagents

So with fertilizers coming in to make larger agriculture items, a thought just occurred to me.

That means you can have giant mandrake, garlic, and nightshade.

Perhaps those should be usable and give a bonus effect. Would definitely give growers a reason to grow and invest points into agriculture.

I'd imagine when animal husbandry gets added that more options could be supersized (black pearls, spiders silk).

Thoughts?
