Lightning and grow box?

Hi mate, you want to have around 50w per plant, for a good grow. I'd recommend getting multiple lights as you can get the most coverage wise. I've got two viparspectra p1000s and the are awesome. A little overkill for my 3 plants but it's better to have too much and dim or raise the height. Have a look at viparspectra, mars hydro and spider farmer. They are the main players in the LED market, I'd say. Viparspectra are a little cheaper than the other two but they are awesome. Good build quality, full spectrum and deliver pretty much the same output as the other 2 bigger brands for less. In terms of tent you'll need quite a big one for 6 plants. Mine is 80cmx80cm and as you can see my 3 plants have completely filled it. They are worth the investment. They help control the temps, RH and smell. Whilst increasing light penetration.
