Behold, my experiment

I occasionally grow Sweet 100's, always with good results.

This time I picked up two plants, intending to eliminate whichever didn't take off (one Sweet 100's is plenty for this household!)

About two weeks ago I planted one of them with coffee grounds, crushed eggshells, a mix of garden (triplemix) soil, dash of potting soil, and bonemeal. I didn't have any compost on hand. For extra measure I sprinkled some crushed sea shells around the stem to keep the bugs away.
The other plant just went into the triple mix without additional amendments.

The two plants are in the same spot, same soil, same conditions. They were in the same cell pack. It's been very hot these past few days.

Can you tell which got the extra special soil treatment :)
