Hopefully this thread will clear up any doubt one might have regarding cobweb.
Cobweb is light grey in color. Not as dense as mycellium. Has a more "fluffy" appearance. It will spread like wildfire if the conditions are right.
Conditions include stagnant air resulting from poor FAE as well as an unsanitary environment.
While it is common practice to spray the affected area with H2O2, for an IMMEDIATE fix, it WILL NOT CURE IT. Your BEST defense for treating and preventing cobweb mold is to maintain proper FAE, eliminating the possibilty for stagnant air. It is not uncommon for growers to LIGHTLY mist the affected area to get the infection under control while they adjust their schedule to increase FAE.
The downfalls of using peroxide are:
1) it causes the mycellium to expend energy to recover. Engery that could be put towards colonizing the casing or fruiting.
2) fruiting time is delayed due to #1
3) causes unnecessay stress on grower
Mycellium at times can look similar to cobweb, especially pan mycellium. When mycellium begins to colonize a casing it can appear thin, whispy and light white until it gets more mature and gets a stronger hold. While mycellium seems to have a standard appearance please note there a few different types.
If you are providing ample FAE and sterile conditions the chance that you actually have cobweb are slim. Please be sure to have a correct diagnosis.
I have attached two photos to help you examine any further questions you may have regarding the appearance of cobweb.
