Coco prof plus is the medium. I have 2 inches of clay pebbles in the bottom and a light mix of them throughout the medium. It is possible I need to add some perlite or similar to the mix.What is in your growing medium? It doesn't look like their is much aeration (perlite is good for this). Part of it could be lack of air/suffocation.
12 inches is too close for an HPS, 18 inches is the minimum distance IMHO. Seedlings are far more likely to survive if under fluorescent lighting (T5/T8 would be good), 2-4 inches away from your plants.
Good luck
Intriguing idea.I cut 2 litter plastic bottles in half and use top half to cover the seedlings in the tent. Twist the cap open or closed to adjust humidity inside the mini greenhouse.. I also use the cap to block or shadow direct light on the baby, Seen some using plastic bags but I don't like that to much. By the time they outgrow it they are ready for prime time.
