How many Lumens do shoot for?

So we have bridgelux gen 2 led strips spaced two inches apart. How many lumens do I shoot for in Veg. 6'x6'x6'and how many in bloom 6'x10'x6' ?.

Well it turns out in veg. with my bag seed Ginny pigs 20,000 lux is good to go. Par meter not here yet. 22,000 lux stressed one of the taller plants. All same bag seed so presume same variety.
