what do u guys think would be better for a 4x4 area?

I'd get the 405w blackstar chrome from Gotham hydroponics. It's $100 more than the advanced but has free shipping. Gotham has given me great customer service. A friend of mine runs the first generation black star to good effect.

Free if ordered through their eBay store that is

I am running 2 of these vipar leds in my 2x4 tent with great results, the customer service is great with vipar also here is my critical sensi star mainlined using the 2 vipar 400w leds

Does your friend use any supplemental lighting? also does he run it for the full cycle?

Sometimes he's ran straight led, some grows he used a hps as well. Big set up I believe. Look up reefbongwell 's grow threads

I purchased them off ebay for $199 each I looked at the link you posted and that is the same ones I have except looks like you would get alittle off for buying them together

Nice mainline, dude! Have you been doing this technique for a while? It looks interesting...I've been thinking of trying it. It looks like it produces a beautiful canopy. How long does it take to get fully grown out before you flip to flower?

actually, this was my first one it is going so well I don't think I will ever do another grow any other way. all and all I figured it added 1.5 weeks to the veg.
