The bud size has continued to increase and the density of the buds has improved a great deal. The purple colors are very vibrant now and the flowers have a strong, but not overpowering, smell when the tent is open. Inspection with a micrsoscope shows clear and cloudy trichomes with the first just starting to amber on sugar leaves. I think it's likely harvest is 1-2 weeks out.
@BigDaddyK, It's all good - I'm hanging it up with this RDWC, though. I'm growing in a garage in the desert and to keep the water temp low I'll have blast the A/C. I'm buying more autopots and packing this system up until December!
