Because It has Cobs on it. You would have gotten 1.5pounds with a timber or cutter 600w cob grow. And it could only get better. For less money! Value. Dank grown for money spent, your amare doesnt stack up. Btw both of your accounts have pics of amare lights as your profile. Just saying.
That 600w kit from timber is too expensive mine didn't even cost half as much to do myself. The bigger the kits get the less they make sense "if" you can DIY. To be fair I am not using as many COBs in my 600w light but this was intentional in design partly due to cost.
For a newb beginner their light source will make less of a difference on yield than many other factors. A 600 watt hps would get someone through their first year of growing just fine for a lot less money or two 315 LEC lights. Will they be the newest best most efficient data sheet winning light? Nope. But until that grower can hit close to 1 gpw in his/her garden the led at those pre built or kit cost is a waste.
Your yield has many factors and guys believe it or not the light is not the biggest when you're not a seasoned grower. People like
@sixstring2112 and
@Hybridway and
@ttystikk can grow under a glow stick and that's what the new guys won't understand. My first harvest earlier this year was a real eye opener once my buds dried and cured. A lot of people making some big claims all the time about their harvest and well I can tell you people stretch the truth lol.
Just my $0.02
