Here's the update from this blog where I first introduced this experiment.
Apparently, they were very easy to sprout. After few weeks, I have transplanted some of them.
It was too late for me to transplant them, I guess. As you can see, I can't separate them from each other anymore. This one is starting to turn yellow.
Based on this experiment, every seed will sprout. So you can sow seeds as little as possible. I am not expecting to harvest from my plants. I trust that it is not gonna be that easy, but I surely will try to nurture them as much as I could. I am preparing to turn my Yard of Weeds into a garden-bed, so the rest of my cantaloupe seedlings might end up there (as well as my tomatoes). I do have red soil (unfortunately), I have researched how to amend it, seems that it's a great hardwork. I'm considering doing the-planting-legumes-method, and see what happens.
Have a blast in your garden today!
