Hi, For the past 2 weeks I have been growing some basil and cilantro plants from seeds. I have been trying to reuse products within my home - my green house was made up of a spinach plastic container with paper rolls as the pots. I used starter soil and misted the plants with some water in the morning before work. I didn't have a grow light - just a 2.5 gallon aquarium florescent light to give the seedlings some addition light. Before they sprouted a layer of fluffy fungus/mold appeared on the top of the soil and sides of the paper tubes. I didn't water the seeds for 2 days thinking all was lost - I thought I must had over watered causing this fungus to grow, but they sprouted anyway. The cilantro I had to re-pot last week because they were getting too big for the container. When I re-potted i looked at the roots and general health of the plant - all fine. The fungus/mold isn't growing on the roots that I can see. Now I have another layer of the same stuff on the soil top of the cilantro seedlings. I have been watering those guys lightly every 48 hours. I am wondering what the fungus/mold is. If the fungus/mold have a symbiotic relationship with my plants (I am hoping the fungus/mold isn't parasitic). Am I over watering? Are they just not getting enough light? The northwest seems to be prone to all sorts of fungi/molds - so is this something I am going to have to deal with for here on out? (I am originally from Michigan and I have planted seeds like this before with no molding/fungi happening...) (The pics show the newly re-potted cilantro and the basil seedlings. Since I took the cilantro out of the "greenhouse" the fungus/mold is now only on the bottom of the paper rolls by the second layer of soil) Thanks for you input!
