So ive got 4 plants i started from some bagseed, they are about 3.5 weeks old since sprout broke thru soil. I switched em to 12/12 2 days ago to keep them really short since im working with limited space. How long typicaly does it take before they will show which sex they are?
They'll typically show sex 1-2 weeks after flipping to 12/12, give or take a few days depending on the maturity of the plant(s).
