Today Celeste D. attempted the first deep clean at Pepperwood, but could not fit strand frames into 5g bucket. So proceeded to clean them with 409 as per SOP. This was the first time the collector was deployed since replacing the power source, fan switch, relay and wires (it has been dry at Pepperwood!). The RH was reading 33% at 4pm and matched the adjacent weather stations readings. I also noticed a few juvenile cockroaches in the collector and sample bottle. They are probably getting in thorugh very small spaces between the plexi and the teflon tray or where the doors meet the collector.
