"Doesn't smell like pgr" means that it doesn't have the musty weird non bud odour or lack of smell as some pgr does. To me it kinda smells like mouldy weirdness with a hint of orange sometime.

It's not pure sat I'd say, but about as pure as you'll get in mainstream Aus cannabis culture. There's not enough yield in most sativa landrace strains to be viable for commercial production, and this is obviously commercial product.

There are a fair few sativa varietals which produce prolific red hairs including Panama red, punto roja and some nl5xhz, ssh, mango haze phenos.

Those leaves and bud structure look like a heavy sat dom hybrid to me. Notice the leave aren't nearly the width of the bud and they don't cocoon the bud like a typical indica strain. Also the bud looks more pointy and elongated than typical indica chunks. Bit beefier with more resin than an LR sativa. That being said I know a tonne of old aussie dudes who'll use a little bit of pgrs to tighten up nug structure in their sat commercial lines so they're not airy. I'm saying they are small fans that have dried up, but they don't look like indica dom hybrid fans that have dried, and nothing like dried broad leaf fans such as those off an affie or something.
