How can I determine the sex of marijuana cannabis seed plants with clones?
As compared to the observation of marijuana preflowers, forcing clones is an almost foolproof method of determining sex. This method anticipates that the grower has started a batch of plants from seed. After several weeks of vegetative growth, the plants should have branched enough that cuttings may be taken. The marijuana cuttings should have at least one node and be at least an inch and a half long.
