My plants are a month to 2 months old, and have about 15 total leaves, but their stem is strong as the second set of leaves grew. Its a indica strain from a good friend of mine, grows small though. I've used fluoros but right now im using mercury vapor lights. I say about another month till flower though. Im surprised on the boards though, people say they've grown their plants for a month, and its already a foot tall, when mine are 2 months old and hardly 6 inches. Im not using HPS lights though, and my lumens is about 8,000. But once I flower im purchasing a 400W HPS.
