I decided I'd trying harvesting my own herb, but I really have no idea what steps to take. I've taken some 'bag seeds' and placed them in water over a 36 hours. The ones that were starting to split, I placed in my bathroom in some potting soil that I had mixed with some blood meal. I put saran wrap over the top of the pot and poked a few holes in it to keep it humid inside. I went out and bought a light bulb from Wal-Mart that looks like a regular bulb but it says 'plant light' on it. I've had it under the light for a few days and I've even seen a root-like tail come out of a few seeds. However, I noticed some white, fuzzy, almost mold like matter on the surface of the soil so I took off the saran wrap to let some air get in. Is this a cause for concern? I'm not really sure where to go from here, any tips? I posted a picture of one of my seeds below.
