Once your seedlings or clones have established a root systemand have "hardened off," they can be transplanted into yoursystem. If you used Perfect Starts or another plug or cube typestarting medium, this process involves nothing more than placingthem into your system and turning it on. If you used a loosestarting medium like perlite or coco coir, you’ll need to use abasket liner to keep the loose material from falling into yoursystem and clogging it. I have experimented with aquarium filtercloth and have found that a fine layer of filter cloth between thecoco coir and net cups seems to work well. There are now coircup liners made from coco fibers as well. To transplant into thehydroponic planter systems described later in the book, dig a small hole in the LECA, place the new plants into the hole and gently fill in the LECA around the roots. To place your plants into net cups and try to get the roots as close to the bottom as possible. Fill in around the roots/sponge/cube with LECA to hold it in place.
