plant spacing

[William Mancuso]

I've got a DWC system and have four questions #1 do pants that were seeded and grown in soil do well transfered in to my type of system? #2 how is cloning done. #3 what is the spacing needed for plantrs like lettuce, turnip, cabbage, pac choy, swiss chard, and calard greens. #4 On a 2' x 4' raft can I plant out 56 plants?
