My First Time Ever Growing

After one full day soaking in distilled water, then sitting in the paper towels for another full day, 3 out of the 4 of the seeds had started sprouting. I then transplanted the 3 germinated seeds into their final 3 gallon fabric pots. I put the seeds into a seedling soil with mixed perlite and mykos, which is then surrounded by FoxFarm Ocean forest w/ perlite and mykos. Overall it felt successful, but I do question if I buried them too deeply, I didn't use a ruler and used my finger, making a hole about an inch or so long, up to the first joint on my index finger, then covered loosely. I have a major concern for one however, after finding what appeared to be a broken taproot among the soil after a light watering. Also found a weird orange, seemingly hollow ball next to it, which when I squeezed it exploded. My instinct was that that was the Taproot and shell, but it also could just be other bits in the soil, as it did have other things like small sticks in it. Will just have to monitor as I don't want to dig around to find out. The following day however the final seed starting sprouting a small root, about the length of the seed itself. Will plant in soil in probably the next 12 hours or so.
