| The quality of lettuce (Lactuca sativa) seedlings is closely dependent on the substrate and the management practice during the transplant to the hydroponic system. This seed bed process may affect the normal development of the seedlings by affecting the post-transplanting period, potentially causing root stress, influencing establishment and even leading to seedling loss.
