I am currently growing Pineapple Express, along with a number of other strains. two are in different stages of flowering , and the last is being vegged out to a huge bush. Took some photos a couple days ago, but haven´t uploaded them yet...I have a grow journal going on where the PE plants are included...its in my sig...the photos should be there today or tomorrow...
the plants look promising though...very short, regular internodes, long, narrow sativa leaves, outrageously fat main stem, big, DENSE buds that smell of tropical fruit with a hint of eucalyptus. The older one is so resinous that theres little flies stuck all over it...it smells sweet, so they land on it, then they get stuck to the resin and die...doesn´t happen with the other plants, and they are pretty resinous too... The branches are very well developed, long, thick with lots of budsites, which leads me to think that this may be a higher yielding strain.
Yours sounds just like mine. Very nice plants, I'm on clones now. Covered with buds, as you mentioned, fast finish and easy to clone. Not very tall but high yield.
