How many watts for a 2x4 growspace

[SSgrower]

IMO go for the best one possible regardless of the price. The thing about lighting is even if the better ones only get you a few more grams, it adds up over 2 or 3 grows and makes it worth it. Plus if you get a low quality one, in the future you'll end up spending the money anyway.

Really! I am daisy chaining 2 Viparspectra 600w & 450w for my new 4x4x7' tent, start date 14th Feb target aim. Cheers! Great advise.
