I've got a seedling going in a DWC clay pellets and it feels like it's growing really slowly. Maybe I fucked the sprout up by planting it right into clay. It poked out of the clay on the 27th, here's a pic from the 29th and another taken today(the 8th). The netpot is about an inch submerged and there are a couple roots poking out anbout 2 inches through the bottom. I've got a 23 watt CFL over it, 3 gallons of dechlorinated tap water at around 65° and an air pump under the netpot. i just noticed a couple dark spots on the leaves today.
