Wouldn't the dirt fall out... lol

How to Grow a plant upside down:
Plants respond to gravity, termed gravitropism, so it would be unusual to grow
them upside down. If you turned a potted plant 180 degrees, the shoot tips would
start to bend upward again within a few hours. Parts of the stem that have
already become woody could not bend but growing shoots could. The upside down
plant would probably survive if the leaves received sufficient light. Lateral
roots often grow roughly horizontally so being upside down would not be as much
of a problem for roots. You would have to water the upside down pot from the
bottom somehow. This would be an interesting experiment.

Scientists interested in growing plants in the space station and on space
flights have sometimes used a pea plant, named ageotropum, that lacks the normal
gravitropic response. The ageotropum pea roots do not respond to gravity at all
while the shoots respond to gravity in the light but not in the dark.

hydrotropism in roots. Science 230: 445-447.

No, you can't. The plant does this thing called Gravitropism where it sends its roots along the force of gravity and its stem against it. It's controlled sort of the same way as Phototropism, how the plant bends towards light sources. So, if you turned a plant upside down, the stem and roots would just reverse growing directions. However, turning the plant over every day would not work, and you would only end up with a very confused and very dead plant.

Yes. but the roots will always grow towards the earth (geophillic / photophobic) and the shoots always grow towards the sun (photophillic / geophobic).

This can be simply experimented by planting the seed upside down.

if you could keep the dirt in the pot, you would have to place the light source underneath the plant. If the light source was above the plant, it will grow towards the light.

You can anchor it so that it will grown downward-- but it grows upward against gravity and most grow towards light-- the only way to grow one down would be to take the shoot and train it to grow towards the ground.

yes and they have special containers for it to.. look in plant supply catalogs they show them with tomatos in them but you can use them for any vining plant.
