Barney's Farm Blue Cheese is probably the most powerful Indica that I have had. As soon as you smoke it, you find your will and motivation bleed away with every hit leaving you in a puddle in a chair or couch. It is more narcotic than the narcotics i've tried, lol. I normally fall asleep within 30 minutes of smoking Blue Cheese.
It is also very pest resistant and pretty mold resistant. If you are lucky you will find the 53day wonder that is the most indica of all the phenos. It is only a medium producer, but what it lacks in weight it makes up for in power.
The smell is unlike anything else I've ever seen. If you get into some true Blue Cheese, you know you did. It actually smells like Blue Cheese dressing. Very cheesy with a sour funky sweetness behind it. If you grow Blue Cheese you will know it when you smell it, and unfortunately so will your neighbors and without good filtration, so will your whole neighborhood. Carrying this discretely isn't possible. It reeks to all heavens. If you smoke it, it stays in your clothes. But besides these drawbacks, it is one of the best Indicas I've had. Not great with pain management, but as for sleep management, it has been in my pill cupboard for awhile.
