I have increased the solution to 642 ppm and the LED panel is in Flower setting (more red) the girls are about to out grow the chamber since all 4 of them are sharing 1 compartment. I need to find a good home for 1 since I only have 3 compartments. I am not going to try and grow 1 outside like I thought.

The girls are 21 days old since they were put to bed in the rock wool, I suppose on average they are really only about 16 days old since they took 3-5 days to germinate…who’s counting?
