I can vouch for this product from amazon, it makes pineapple plants flower. I put some pieces straight out of the can on the tops of two pineapple plants and drizzled a little water on top. The water makes the calcium carbide fume and smoke, so if you put too much water it will run off. Furthermore, it also burns the leaves, so too much calcium carbide is not good. I put about 3 to 4 small pieces on each pineapple top.
The top center will look burnt, but it recovers, and a flower forms. It took a couple of months on just one application.
