What about taking the roots of a plant thats one sex and splicing a cutting of the other sex on it?
I heard theyve used this for clone only strains to produce male plants but im not sure how it worked or if its very hard.
I know growers splice other plants like grapes and tomatoes and roses to starts them growing in a solid root system or even a different type of plant that has an established root system.
im pretty sure you cant with STS or the ones that turn females into males. Its a one way street i guess?
