Have 2x4x7 tent with 400 watt aircooled light and will probably be able to grow only about 3-4 plants. Do I need a co2 in this tent? Thanks
For a new grower, I would advise against adding extra co2. Keep it simple! Just use good ventilation and "Learn the basics".
You can always add co2 later - once you get good at it!
