ganja, you need to smoke a j and quit blasting people like a dickhead for asking a question. maybe he never has grown a thing before. everyone starts out with zero information and learns as they grow.
as a matter of fact, it may be possible to grow and flower a plant upside down. if the light is benieth it, certain hormones will cause the plant to grow towards the light. however, you will also have to design a system to correct for gravitropism, the natural tendancy for a plant to right itself and grow upward, using gravity as its positioning agent. i believe the roots will grow down for this reason too, so how would you feed it?
omega grow wheels rotate a plant between upright and upside down specifially because it causes the hormones to disperse evenly since it never stay in one position for long.
it may be possible, but it would need to be a very sophisticated operation. if you figure it out, let us know.
