Well so far these plants have blown my expectations out of the water for auto's. The tent is absolutely packed, wall to wall full and some of the highest tips only inches from the lights! You wouldn't believe I did a good defoliation on Day 43 but ya I took a garbage bags worth of leaves from the girls and they didn't skip a beat! Lots of airflow, and better light penetration now. Reoriented the AC clip fan to back right corner, turned out she's the lowest plant so best place for it. Have the other two clip fans as well on same pole, one at bottom of canopy and one on roof for the driver cooling just to be safe. I really can't wait to see how the rest of this grow goes, I'm a little excited and nervous at the same time with the size of these girls. The buds are filling in very nicely, could end up with some massive colas in the end! Already seeing two pheno's in the tent as well, hoping for some cool colours! Frost is already present on #3 😁. 650-700 umol/s Fans ~70% power for 4" intake and 6" exhaust Plant height is average. Canopy 50" tallest 56". Light height 14" from main canopy. Closest 2" Later growmies!
