I'm starting to think I have a blackberry kush strain (I knew it was a blackberry cross, but didn't know what with), this thing just won't grow vertically at all. It's going on 5 weeks old and still 4 inches tall.
I'm growing a freebie from Attitude, White Siberian, that is huge. After 5 weeks flowering she has a 16-18 inch main cola
and 16 side branches each at least 24 inches long and each with buds at the ends.
