Everything looks good man. What are you? About 4 weeks? Keep it going. Start checking the trichomes at 8 weeks flowering, but be prepared to go to 9-10 weeks as Jack Herer goes 60-70 days. Not sure about Jack No. 7 but my experience is nothing is done in 8 weeks. Always 9 minimum.
How do you like using the tents? I use them and like them to control the environment without taking up the whole room with my operation.
