This is day 41 of this grow, and I couldn't be happier. It's crazy how it is changing to a deep dark purple, changing from the inside out. They have started to produce a heavy amount of sticky crystals over the past week. This is the second time I've grown the Blackberry Auto from Fastbuds, back in January I grew this strain, when harvested it in March the main stalk was hollow. Just like a drinking straw! So this time around, I decided to add Silica Blast. I believe that was the result of using much weaker lights. But a very good smoke!
