- The greenhouse gets worse; white frost under the film
- Same greenhouse vegetables for four years. More dead plants this year, a white film at the mulch edge.
- Salt, disease and burn arrive together. The film is an umbrella, not a pickaxe — salt has nowhere to go. Read EC. Flush only if water can leave. Replacing the soil is the last step, not the first. Rotation beats another sterilisation.
