besides overwatering being the main factor, make sure that your temp stays steady (between 68*-78*) and doesnt drop below the mid 60s then raise up high, that variation isnt good. also make sure your humidity is constant and not able to spike up real high(need good air ventalation). i had lil mushrooms on my first grow, i realized it was un-steady conditions with overwatering. hope this helps you:thumbsup:

G13budsmoker Reviewed by G13budsmoker on . Mushrooms? Checked on the babies this morning and had mushrooms around 3 of the 5 plants. Last night, at 9 pm, they weren't there. They were about 3 inches tall with white stems that had black tops (not really caps) that were like black slime/paint. These plants havent been watered in 3 days and aree due for a 2.5 gallon drip tonight so I dont think they were over watered. Any ideas? Are shrooms bad? Thanks! Rating: 5
