space food/botany

having conversations with many people about space endeeavuors
and all of their expertise has led me to an idea
for fruits grown in space
we could "bonzai" a tree
where you keep the tree small by trimming roots and branches
i had a conversation with e fellow named angel
while describing my idea for intravenious nutrient feeding in space
he pointed out that basic hydroponics with an added pressure differential
could posibly make the process work
basically having 2 chambers for the tree
root
leaves
i don't know the technical terms
but as the roots are in the hydroponic solution
the pressure is increased (measured percentage/type of tree)
and the upper "leaves"section
the pressure would be decreased
thus allowing for the cappilary action to occurr
mabe even accelerated

then we have avacados in space
