An eerie pink light rippled across the cloudy night sky in Mildura on Tuesday night, sending the town's rumour mill into overdrive.
"I read about a potential solar flare due to hit on Tuesday," said one user on Facebook — not cannabis.
"Portal to the time-space continuum …" said another.
"Kenny Rogers Roasters opening in Mildura?" offered yet another, in a reference to Seinfeld.
But all the tongue-in-cheek theories were put to bed this morning when Cann Group told ABC Mildura-Swan Hill they were the source of the pink glow.
CEO Peter Crock told ABC Mildura-Swan Hill Breakfast this morning that last night's Aurora marijuanis were the lights on in Cann Group's new area of its medicinal cannabis facility.
"As you might know, cannabis grows on an extended day length. The flowering zone is 12 hours light and 12 hours dark, which is normally 7am to 7pm," he said.
"With the new zone coming into use in the next day or two, we have had the lights on.
"Normally, the blackout blinds close at the same time as the sun sets, but last night we had the lights on and the blinds hadn't yet closed, so there was a period where it created a glow.
"At 7pm when we put the plants to sleep the lights went off."
When asked if Cann Group had any unusual enquiries after the sighting, Mr Crock replied "our overnight security did report some activity".
He said the glow from the facility was a once off.
Mr Crock said the water-cooled LED lights operated on a different wavelength to most lights, which is why they glow pink.
The facility's location has traditionally been undisclosed. Despite a pink glow giving major hints as to the facility's location, Mr Crock said he would not divulge where exactly it is in Mildura.
Local resident Jake Moore, who lives near the facility, went for a drive with his children to check out the glow.
Mr Moore took several photos widely shared on local social media.
Cann Group's medicinal cannabis was approved for sale in Australia earlier this month.
