It's going to be my first attempt at growing. So far the setup I have in mind is a 400W Nextgen mh/hps above four plants. I'll most likely use the Scrog method for this grow. Its going to be in a grow tent and the space I have is 3ftX3ft and 5ft in height. The heat from the light will be vented out by an inline fan, that I plan on connecting a carbon air filter to as well. So far I have one Skywalker clone but I think im going to get sativas for the rest. Does that sound like a decent amount of space for 4 plants under 400W? Im kind of worried about the tent not being tall or wide enough to fit everything
