// Definition
Laboratory technique for producing sterile plant tissue by culturing meristematic cells under aseptic conditions. Eliminates bacteria, viruses, fungi, and pests from the plant material at a cellular level, producing truly clean starting genetics.
// From the Episode
Bubbleman (SPEAKER_11) noted tissue culture goes further than pesticide treatment because it addresses bacteria, viruses, and fungi impregnated in tissue, not just surface pests. Fletch acknowledged tissue culture as the gold standard but emphasized that growers without access to a tissue culture lab can still produce sterile tissue through proper systemic pesticide application. Jenn Doe (SPEAKER_01) confirmed that without tissue culture, persistent resistant pests require complete environmental decontamination.
