I looked this thread up because when I was attempting to water the jungle, I noticed a number of leaves that were very glossy/shiny and had little serrations on the leaf's surface. The plant is from 30+ year old strain that is very tall and lanky, supposedly the Matanuska Thunderf%%k from the Alaska pipeline. I have had the seeds in my personal possession since '78, so I know they are old and not bullshit. Anyhow, I have been growing this strain forever, mainly from beans that still pop every now and then. I have never noticed the glossy leaves before...they look like they were sprayed with shellac or clearcoat. The plant is tall and lanky with long gaps between nodes. I thought it had a lot of Sativa because of the narrow leaves and tall, lanky structure...but who knows. The glossy leaves are all on the lowest branches where the only buds you get are kinda wispy...but the leaves are unique. I have a couple of sister plants I'm gonna check for the same, but so far it is just the one large Thunder.
