the best method imo is to veg the plant until it shows on it's own(preflowers). most plants show preflowers between weeks 4-6 anyway. growing mj is a hobby that takes patience.
justaseed Reviewed by justaseed on . Sexing Questions I pretty well know how to sex mj plants from seed. But, at what age or size should you start sexing your seedlings in the 12/12? Can sexing them too early cause high rate of males or is this disposition already programmed in the genetics? Thanks all:thumbsup: Rating: 5
