I have grown Barneys Farm LSD and its a good strong strain. Easy to veg, but requires lots of "P" in flower. Mine also had some cal-mag issues, so adding cal-mag plus @ 1tsp per gallon on every watering should keep you from have that issue. The best bang for the buck is to paint your walls with a flat white paint, its better than foil but not quite as good a mylar, also make sure you dont have any light leaks, I have read people having issues with LSD going Hermi if you have a light leak. LSD is a bushy plant and mine only streched about 50% in flower. You can search in the grow journal section and find several complete grows on LSD, including mine. Good luck and enjoy.
