Interesting analogy... I assume you're talking about a 1 seater bmw motorcycle vs a 5 seater ford truck? I'm all for people buying quality if they can afford it... and efficiency is important too... but you just can't get away from the fact that more watts = more buds. Sure use those watts efficiently and its going to produce better... but... if you talk about whats the max amount of bud I can harvest under my 330£ led... how much bud do you think you will get under a GN unit vs £330 worth of chinese LED? Not too sure on the exchange rates... but I think I could get a 600w actual draw chinese unit for under £330 and with a pro grow pull 600grams from a grow with it... whats the most you could hope for under a new GN unit....? Feels like throwing money away to me...but hey, its your money.
