try couchlock by british columbia seed co. lives up to its name!!! seems you want a high cbd strain for the couchlocking efect. brazil amazonian, columbian gold,or just about any pure afghani should do the trick..nirvana seeds misty was an all time favorite couchlock, fast flowering and great yield to boot..dont know why they discontinued it?? but if any one can find nirvanas misty ill pay for those seeds!!!! White widow is all the rage however i dont find it to live up to the hype and ive tried cbd's ww, sensi's ww, greenhouses ww, and im about to try seedsmans white widow, hope its better than the others!! bit seriously if you truly want to be drooling on the couch, couchlock by british columia seeds its pricey $14.00 a seed but you only need 1 female as i bought 10 and all females were identical and believe me when i say i couldnt keep it to cure, the second it was dry i had people waiting for it i barely got to keep any for myself.. 1 or 2 hits for veteran smokers and within 15 minutes couldnt keep their chink eyes open!!!
