Polar express

Growth stated taking off. Nearly doubled in size from last week. Roots are beginning to fill the 2 gal pot. I am considering LST on the main stem to allow more light to inner nodes The node spacing is extremely tight right now. The ppfd at the canopy is about 615 and she seems to be doing great, so I don't think I will raise lights at all. I have seen in other grow diaries they start to flower around week 6. Hopefully I can get another 12" or more out of her in next 3 weeks. That will put me at about 36-40" height at end of flower which my flower room is 72" tall. This gives a good buffer from light max height.
