Just wondering how big the plants should be before starting 12/12?My plants are only about 8" tall but are on their 5-6 nodes.Wondering if I could start flowering them or should I wait? I am not worried about yield right now as this first grow is for experience only.Thanks
How much vertical space do you have? Marijuana plants will likely almost triple in height when flowered so if you flipped the lights now, you'd end up with 2 footers when they are finished.
