Yikes 4 or 5 feet? No don't do that!

Kannabis plants will grow 1/3 to 2/3 more taller in flower cycle. You would need a very tall ceiling for a grow that you suggest.
Kannbis plants need a 12 / 12 day night cycle to flower properly. Some strains show pre flowers but not buds if in the vegetative cycle.

Good Growing!
