I got his 9 plant hydro box. It does cut down on startup but they are small pc tower size (the lowryder boxes). I'd get the biggest you can afford. Problem with the small cab is temp control. It has worked great but I added a 150w hps and adding a much bigger box for later grows and switching to a veg/flower setup. For the cost I would look into a DIY box, wish I had as I would have put more money into lighting and cooling. Lesson learned.
