Hey nice first grow. I've got a new Blackstar Chrome 8 Series and I'm curious as to how many plants to put in a 2x4x5. I'm thinking about doing 2 - 8 site hydro tubs that would hold a total of 16 plants but I'm not sure if that would bee to much for that space. Just wanted to see your input based off your last grow with a similar light source and environment.
