@Turkishdelight,Thanks man, well what i can say is i use 2 panels of QB 135w i ordered them from https://horticulturelightinggroup.com But i guess if you order them on alli express they can be good .
I'm not an expert on lights but i have noticed the difference between Normal Light,Viparspectra and when i bought my QB's.
And just looking at the results i'm getting without a lot of trouble and if i see people struggling to get decent harvests i think you can say that Lights are the most important thing.
Since i start using them all my harvests are 400/500 gr and even my bruce banner /royal gorilla got me 577 gr of dry weed that's 2,13gr per Watt in a tent 80cm/80cm/180cm .
So i'm conviced that QB's are the way to go with those banging results ! i still believe i'm dreaming when i harvest.
