That setup is Legit bro :clap:
Another setup is 5 x HLG320 @1050ma + 20 x vero29C 70v COBs = 1500W over 4x10 area
:leaf: Growmau5 got 4.6pounds from 1500W as seen in video:leaf:
3ft is good height for now & just tell granny not to overwater cuz plants hate wet feet.
How old is plant:confused: if over 1 month then throw it out & plant new seeds cuz in 1 month with 18hrs/day should be 1 foot tall plants.
Dont overwater & no nutes for the 1st week.
Throw ur blurple light in the garbage & keep temps around 80-85F
good luck :leaf::leaf::leaf::leaf::leaf::eyesmoke:
go with the A version drivers cuz they have built-in dimming on driver with adjustable screw.
Also ask questions about QBs & drivers here >>>> https://www.rollitup.org/t/diy-with-quantum-boards.927159/page-425#post-14019551
Most of questions have been answered in above thread:weed:
ask @Stephenj37826 or @robincnn if u can preorder the QB132 because they sell like hotcakes but they try restock asap,
good luck bro:leaf::leaf::leaf::leaf::leaf::leaf::leaf::eyesmoke:
