Rooting hormone is recommended, but not required. Better with 2 cuttings per cell. Liner can be pinched at 3 weeks or when well rooted. Maintain uniformity in mist and soil temperature. Do not allow cuttings to wilt. Pinch to increase branching. Avoid overmisting. Apply preventative fungicide at 3-4 weeks. Avoid stretch by moving crop to cooler air temperature in second and third weeks of propagation. Transplant on time.
