I am new at growing with seeds and I have several seedlings growing. I'm not sure how to go about sexing them? Should I clone all of them when they are large enough and put the clones on 12/12 then remove the males? Can I put the clones on 12/12 right away or should I root them first? OR Can I simply put the seedlings i have into a 12/12 cycle when they are large enough for a week or so until I can determine the sex then return the plants to 18/6 cycle? Will the plants recover ok? Will they go back into veg? I don't want to ruin my efforts!
