I grow Sour diesel & Blue Widdow in single cola sog & have good luck with both but i have to keep a close eye on the Sour D for bud rott .
Strains that are chunky with swollen calyxs like blue widdow do better than the strains that are real hairy like sour d .
Ive found that strains with buds that are mostly calyxs vs strains that are all hairy with pistils tend to fair better in tight areas with lotsa moist leaf material .
