sure you can expect a good veg cycle with these but in flower you'll be left wanting.
you could maximize your penetration with a trained canopy, like a small scrog.
there is no "quick turnaround" btw, or else everyone would have a quick turnaround all the time.
The plant will take 60-90 days to finish this way
2 18 watt tubes growing 12/12 from seed you can expect returns to look similar to a martini umbrella.
better results would be had leaving your ideals of "quick" behind and vegging the seedling for a few weeks first,
but all in all, your sucky floro's will make sucky marijuanas
