In case you're wondering about the floating rafts (deep water culture), this is what it looked like this morning. I've got lettuce (2 kinds), watercress, spearmint (2 kinds), ong choi, marigold, basil, kale, Swiss chard, and fennel. The nitrate levels are slowly creeping up and thankfully, nitrite levels are lowering so I am hopeful that this batch of starts will do well. The one before this failed miserably ... no nutrients means sudden death for little seedlings! Lesson learned.
