Growing 3 Pineapple Expresses now. One is in 5th week of flowering. The buds and cola are solid, resinous, and are getting bigger by the day. The smell is fruity, sweet, fresh and exotic, though not specifically pineapple. Looks promising.
The second PE is in week 2 of flowering. This one was fimmed not long before starting to flower. Being LSTd for the first couple seeks of flowering. The branches are also being trained with wire (same as PE1).
Third PE is being vegged out into a big bush. It has been topped twice and the top two branches have been fimmed. It is growing in 10 liters of organic soil. The reason I picked this one to veg out for a long time is the long, super narrow sativa leaves, combined with VERY short, regular internodes, well developed branches, thick stem, and overall vigor.
