So, you are looking to grow some pot, and you are deciding which species to grow and which strains you want in your garden.
Regardless of the species you pick, you still have to set your lights properly for your plants to grow in their vegetative state, and then change the light cycle when you would like the plants to begin flowering.
Unfortunately, not all strains are ready to have their light cycle changed at the same time, others need more time in vegetative growth.
What do you do? Well, farmers have methods to separate strains, picking strains which grow at similar rates and plan ahead for such issues when they occur.
That is the status quo in the weed world, and most pot farmers live by these rules.
