so... can i just flower whenever the hell i want by switching to a 12/12 cycle? i've heard go about half the height you want and switch, is that true?
Really a third, but a half is close. Typically 6th node on the plant means you can flower. Good rule of thumb for me is 6th node. node - where the leaves grow opposite each other out of the stem
his idea is probably a good one, but i personally flower whenever the hell i want. and yes i would say your plants will get two to three times bigger when you put it into flowering.
