hi,
please like if you enjoy
the green wall i made it pretty easy
you can extend the system with regular 80mm pvc pipe pieces
it is also best to use sprinklers in the module reservoir but a hole will also do fine
for best results use 100 infill and nylon to print and the slower the better

its a easy system even for the first time grower (combo above below)

you wil need;

-- cotton cord aprox 5-10mm (the bigger the better but shoelace also works)

-- 8mm tube and pump (you can also give water by hand)optional with sprinklers

-- screws with 6mm head or bigger (nail also works)

--pots or soil bags (link below)

--black filement (if not the darker the better otherwise you risk algea grow)

--and plants off course (combo from picture down below)

extra info;

--for outdoor best to use UV protective epoxy (keeps it waterproof to)
just 1 layer epoxy painted on the module no glasfiber and best not the bottem
i find it best works best with small organic grow bags and a light soil mix

-- for indoors if your area is dry and hot best is to use terra cottem (link below)

--if you do Drain to recycle water system best is to use a airpump and enzym
to stable the PH also its best to use perlite in the soil mix

-- when very hot and dry use terracottem in the soil and a little bit off hydroponic rockwool in the wall module but be carefull not to block watertube (link below)

the module tube is 80mm like regular rainpipe
print size is 128x80x100mm
the pothole is aprox 54x54x70mm

enjoy it M_X
