Purple Queen photoperiodic. DWC,LED

After 60 hours in wet paper towel the seeds had grown a shoot of approx 150mm length. They were then moved with tweezers into Root Riot propagation cubes which had been soaked in water pH 5.8 and hydroton clay pebbels I kept the humidity around 65-70% and lightly sprayed small amounts of water onto the surface of the basket nets daily. After the first bladed leaves were growing I used a syringe to top feed 20ml of weak nutrient solution (0.3EC/150ppm) to top feed each seedling. I did this twice this week with 48 hours between each. The baskets are in a tray filled 2cm deep with weak nutrient solution pH 5.8. When there are a healthy amount of roots coming through the basket and that are long enough to all reach a resevoir, then I will move them into a resevoir. Until then I will continue to top feed for the rest of the week to make sure a big root network has grown through the basket net. Please note the 660w LED is dimmed to 25% which is approx 350umols per second.
