Growing in Buckets = Less Contamination?

I just read the following quote about oyster mushrooms from this website https://onlinelibrary.wiley.com/doi/abs/10.1002/jsfa.5827
"The rate of contamination in buckets was significantly lower than that in bags: 9.28 ± 2.12 and 12.60 ± 3.73% respectively."
Doesn't make much sense to me, how can growing in a bucket cause less contamination than using a filtered grow bag?

Do you have the whole article? hard to tell what their getting at without reading their methods.
i dont know how buckets could reduce contamination especially with continued re-use. Also you need to factor in time/resources used in cleaning buckets vs cost and resources of PP bags.
Anyways im not a fan of bags but they're practically the one and only necessary evil of mush cult.

I wish I did, if I end up paying for access I'll post the relevant bits from it

Rate of contamination The rate of contamination was found to be significantly lower (at the 0.05% level) in perforated buckets (9.28 ± 2.12%) compared with the rate in polyethylene bags (12.6 ± 3.73%). Since the polyethylene bags were not completely removed from the beds before being transferred to the cropping room but only split longitudinally to facilitate the emergence of fruiting bodies, the continuous presence of a film of water between the outer surface of the bed and the polyethylene results in decay of the substrate and spawn, leading to a higher rate of contamination in the polythene bags. At the same time, spraying plastic buckets with water twice, coupled with high relative humidity, maintained by moist sand on the floor of the growth room maintains the optimum moisture level with no retention of a film of water on the bed surface. This situation leads to quick coverage of the entire bed surface with a thick mat of mycelia mat (Fig. 1).12 The thick mat of mycelia protects the beds from further bacterial or fungal contaminations

quite confused so you get more contamination if you leave the bags on, but you don't want to take the bags off either or the mycelium risks drying out too much
thanks for that link anyway

There you go.
If that sci hub link ever stops working, you can search for sci hub mirrors on google.
