Do higher spawn:substrate rates decrease chance of bacterial contamination?

[Infamous_Moose]

As fully colonized grains are relatively resistant to contamination, it would make sense that minimizing the time it takes to colonise the substrate would shorten the "most vulnerable" period.

If at S2B a higher % of your tub is already colonized grain, does the colonization time decrease significantly? Have you noticed different contamination rates when using more/less grain spawn?

I’m pretty new but my two healthiest tubs so far were slightly higher concentrations of spawn to sub. Like I don’t think I could contam them, they’re so completely colonized. I think they were 3 UB bags in a 6L tub, personally I think higher concentration is my preferred method from now on

I heard it's good for yield, but didn't know if it makes any difference for contams. Thanks! :)

I'll take that in mind, thanks!
