These are a couple weeks old. I think I have around 30 sprouts. I started them under a single bulb 2ft T5, 10000k and a 70w high pressure sodium. I've ept them under 24 hour lighting from the beginning. They are going to stay on 24 hours unless I notice a decline in health.
I was hoping for some colorful seedlings and it seems every single sprout is either orange, red or purplish in color. I wonder if its because of the intense light or the extended photoperiod? They're growing fast and dont seem to mind the 24 hour lighting.
