I'm sorry if you have answered these questions in posts already but I am a nooby and am trying to plan to the fullest extent. I am going to run a quick aero setup(which you posted previously) with a wonder woman hybrid. I am using 400W hps/mh with a digital ballast and 6in airflow vent. I know that you like to switch to flower as quick as possible but I am wondering if you have had better results letting them grow to 3 or 4 feet before flowering? Also, have you used the lollipop method as well as topping? I am planning on using CO2 with a controller and running an A/C unit in the same room to keep the temp around 75. I have a 633GPH pump but I am afraid it is too much for 5 plants or if it makes a difference. I figured that more flow can't hurt and then if I want to make a bigger setup then I would have the flow. Sorry for any redundancy but I you are basically my hero when it comes to growing bud so I couldn't think of anyone else to ask. Any advice is greatly appreciated.
