Help starting seeds please. :)

What's up everyone? I recently came across some Burpee seed starting pellets. Has anyone ever used these to start seeds? It says they are made from natural coconut fiber. I'm trying to start some Deep Purple seeds for DWC and I stupidly forgot the rockwool at the hydro store. It's about an hour and a half drive for me so I only go once every few months. Does anyone have any suggestions on the best way to start the seeds? I thought these coco fiber pellets might work well but I'm not sure...or if anyone has a good way to start seeds for DWC without rockwool. I would really appreciate anyone's suggestions or experience. I'd order some rockwool online but the seeds are already soaking.

thats perfectly fine

My question really is, can I put the seedling, peat pellet and all, right into the system in hydroton? Won't the peat dissolve into the bucket, making the water nasty..or cause fungus probs?
