3/16 - they’ve both developed their first set of leaves and roots are looking good. Time to transition to RDWC. Cleaned/sterilized the system from last grow and transplanted with one layer of LECA at bottom and then 3” Net pot with RR surrounded by large LECA with the old smaller LECA at the top to block out any light. Top fed with 230 PPM solution and covered with domes. Water level is ~1” below net pots with ~10 gal res.
3/17 - top fed from res.
3/18-3/20 - top fed from res.
3/21 - roots have hit water within first week. So much better/quicker than the first grow.
