LED lighting with T8 bulbs

I’m using T8 4ft lighting using 4 double lamp fixtures. Mybokants are about 30 inches now and look great and are now in transition. Is this enough light for blooms?

I would suggest more light for flowering. Those r ok to veg but u need alot more light to flower if u want good buds


So eight t8 bulbs total? How big is the space? Seems like you would need quite a bit more.
