Starting seeds in coco coir?
I'm planning on starting my lettuce seeds up soon for my DWC system. I got myself a coco coir brick and I'm planning on putting some in small pots, placing them in a mini-green house, and letting them grow enough roots to put in the system. This would be my first time starting in coco coir, previously I have started with the jiffy plugs, and want to make sure I'm doing it right. Also, once they're rooted, should I just put the coco coir and the plant onto my hydroton filled net pots, or should I just transfer the plant? I also want to see if anyone has mixed the hydroton with the coco coir as a medium, and if so, how? Mix it all around? hydroton on top, coco coir on bottom? Any other type of combinations? Any help is appreciated.
