    This is my 4th grow in a row in a monotube with a fully- IMG_3461.jpg colonized quad quart jars of rye berry cultures with pasturerized horse manure from a reputable supplier. On each grow, within 2-3 days, this white culture seems to be colonizing the surface of the substrate. I have OCD and have followed every possible sanitizing procedure in the books and yet it has happened again. I have no clue what this growth is, but it is clearly repeatable in my grows. I sprayed the substrate with Sodium Peroxide today which is all I can think to do. What am I doing wrong?

    It still looks like its colonizing. Could you take a close up picture of whats concerning you.

    Redcat,
    Thank you for the response. My concern was with this, and the three former grows, was that this "growth" completely covered the bed within 3 days. I seemed to recall that the colonization of the mycellium took weeks, not days. The grow seems to have a nice earthy smell, quite pleasant. Maybe it is not a concern, I sure hope not. Thanks again for the response.

    Looks fine to me. If anything Id me more concerned with the bare spots...If the mycelium isn't occupying that space in time then something else is.

    Usung WBS will colonize faster than someone using the same quantity of popcorn for eaxmple. So if you used small grains then expect faster colonization due to the amount of innoculation points. Using more spawn will also colonize things faster. What was your ratio ?
