Nearly everyone will tell you to grow northern lights #5, probably from BCSC which is a good choice but I would like to add to the list.
Bogglegum--BOG seeds
Shiva Skunk--Sensi
Jiffypot x F'in Incredible--VISC
Oakland--reeferman seeds
If you are researching well and use the right amount of nutes for whatever type of growing media you use, these strains will grow super strong and fast.
There are a lot of other strains out there....just tired of hearing NL all the time.
