I am not really finding much difference bro,my girls are still finishing between 70-80 days but all i have to compare with is a cheapo chinese led light,i think i am going to make another light exactly the same but with more red in the spectrum maybe 3000k 90cri i should be able to see the difference then,i already have a brand new £60 driver because my first one never turned up so they sent me another driver and then the other one turned up 2 weeks later lol
