Purple J

I plan to put one seed in a glass of sterile water and one seed in tissue culture. The seedling that I started in H20 opened up, sprouted, and then broke. A bacteria caused the root to break, I tried to use tissue culture to bring it back. I washed it in bleach water, rinsed it in distilled water, put the tap root in rooting hormone and placed it in Agar in the test tube. Three days later I found mold on it. The seedling that I started in the Agar seems to be healthy and strong. It is on its second set of true leaves.
