Oh I forgot to mention c02. You really don't want to go here for your first grow. Get your feet wet first. You're looking to get a high gpw (gram per watt ratio). Most consider a grow to be dialed in when they have reached .9 or 1+. At 1 gpw you will have a gram per watt of light so you're looking at 400 grams for a 400 watt light.


In conclusion, don't worry about c02 until you are reaching high gpw without it. C02 involves running timers to slow or stop ventilation when c02 is released for short durations and that can all get fairly technical.
