1.4m = 4.6 feet so 21 foot with what you picked out it would give you a ppfd of 465Hello
I'm bay 12 pcs Citizen CLU048-1212C4-353M2K1
I want to give 2 pcs HLG-240H-c1050a
I think it will be 436w
Is good idea for growbox 1.44m2
or what will be the best driver for this 12 pcs cob
No you would need 6 for a ppfd of about 970Thanks
I'm thinking about this
4 pcs CLU058-1825C4-353M2K1 (I changed order)
3500k @ 2100mA
End I thinking about ppfd 900
