Seeds can be started at 12/12. They will not flower until they reach sexual maturity. If you grow a seed you will notice that at some point the leaves grow alternately instead of opposite. This is when flowering will kick in if 12/12 is used. The only problem is that the yields will not be close to the full genetic potential. But if you are not looking for good yields it will work no problem.
JD1stTimer Reviewed by JD1stTimer on . Flowering early What is the least amount of time necessary for vegetation? How early can the flowering process be started? I'm looking for a relatively small harvest and have very little expectations. Just curious for a short fast grow... Rating: 5
