Preflower Sexing Regular Seeds

by justicebzwieg » Mon Sep 21, 2026 7:39 am

Regular seeds can be sexed a few weeks into veg by checking preflowers at the nodes, well before switching to twelve hour light. Catching males early saves space and nutrients that would otherwise go to plants you will cull. The sexing guide on https://potentthcseeds.com has close up photos showing male and female preflowers at various stages. With a loupe and some patience it becomes routine, though very young plants can still fool you.
