Winding Down Batch 1 Have been harvesting pretty regularly. Enjoying the produce thus far. Seems like the fungal or mildew or nutrient lock issue is spreading from Tiers 1 and 2 to Tier 4. So perhaps it's time to wind down this batch and to clean the system. Target system clean is 18 Mar, during the Mar hols. Will experiment with new batch of lettuce, with dedicated equipments (scissors) and portable fan for top up tiers and to apply crop rotation. Hypothesis here is that with crop rotation, each batch of water nutrient mix can be further prolonged. Will harvest the Red Oaks and Lollas till then. Also have to start thinking of a plan to transfer the Basil too. Thanks to a fellow YH enthusiasts, improved the water level indicator with this mosquito prevention net.
