I've done GWS one other time, I yielded almost a pound, one of my heaviest ever. It was enjoyed by myself and many others. I just got a request to do another so I did. It has both heady and body effects, not a very social buzz IMO. Good nighttime high. Easy to grow.
I love so many strains it's hard to keep up with most. I've done pineapple express, got a little over a QP and it was amazing weed but the smell factor when growing is huge and it has been the only strain where I could smell a hint of it outside my grow room even with a carbon filter and negative pressure. I liked the Barneys pineapple chuck better. More yield, less smell and just as potent as express.
Sounds like you need more lights or something to yield more. What size pots you use?
