🧬 Genetics & Seeds

Strain Reviews Reviews of specific cultivars as grown, not as advertised: how a packet actually performed in a real room or field, what the phenotypes looked like, and whether the plant resembled what the name promised. Tissue Culture & Micropropagation Propagating cannabis from small pieces of tissue on sterile media rather than from cuttings in a tray: media recipes, hormone ratios, contamination control, acclimatisation back to soil, and the meristem work used to clean a line of virus and viroid. Breeder's Lab This board is for growers who make their own seed instead of buying it. It covers choosing parent plants, making a cross and selecting the best plants over several generations. It also covers feminized seed made with silver thiosulfate (STS). STS is a silver solution sprayed on a female plant so that it grows male flowers. Autoflower Autoflowering cannabis, which starts flowering on age rather than on day length. Where the trait comes from, what it costs, and why most of the standard advice from photoperiod growing produces a poor result when applied to it.
