I'm contemplating buying two tents to grow in. One for veg., one for flower. What benefits or advantages are their for tent growing? The thing that's drawing me towards them is the fact that it neatly contains everything. Is there any brands to stay away from? I was looking at lighthouse tents, they seem to be built well. If I go with a 600w hps light, what is the maximum sized tent for that light? Thanks in advance
