hey newgroweroldsmoker. If you have an HPS system of light I would look into getting a MH conversion bulb to veg. I started with the HPS and it kind of wanted to burn my young plant, too much red light. I got the MH and they loved it. Check out my thread (how's my girls doing). I am just past 21 days of 12/12. I only vegged for 21 days and they were 24 inches then. They are 30 to 32 now. Had a little nute burn and am flushing right now. It's a drip system, what are you using ? Any way good luck hope to see pics soon. I will update mine today or tomarrow.
