Isn't Light Warrior Fox Farms seed starting mix? It's pretty much straight peat with some EWC and the jiffy is mostly peat as well. I didn't think it was designed to be used for more than just starting seedlings not for a grow medium. Even so, though seedlings are pretty damn small for 17 days from seed. They look like 5 day seedlings. They don't look bad but they should be much bigger by now. Were they all started in those peat pucks?
