Alright, for all the poor men and woman who live in a urban environment and have a balcony no matter how small it is.
You can still grow vegetables or other plants with little spending.
(while constructing I hold this board up between two folding chairs, lol)
Under construction:
Basically it's just a board with plastic bottles, ring hooks (to run a piece of steel wire through) and hooks screwed in that goes 90 degrees (to hold the bottle up).
The steel wire is just to keep the bottle in place.
And the close up.
Nothing in there yet but there is room for 20 bottles/plants
This board is 2 meters high and 90 cm wide.
And as working on things like this goes (handyman stuff) I'm really handicapped. So if I can build this, anyone can.
