Pyramid White Widow Feminised Autoflower 15 days old
Well at 15 days since putting these seeds in the rock wool I see they have their third set of leaves, not counting the cotyledon leaves, I like it nutrients still around 170 ppm mist cycle 1 second on 10 minutes off, seems to be providing enough solution for now.
