Modular Hydroponic Tower Garden

Description

This is a modified version of [archipelagourbanfarms'](https://www.thingiverse.com/archipelagourbanfarms) [Modular Hydroponic System](https://www.thingiverse.com/thing:2403922). ### **New** [Hydroponic Water Pump Controller](https://www.tindie.com/products/19512/) available for sale on Tindie. ### **Features** - Modular structure, easily scalable, put modules together, twist & lock, done - Module adapter to be glued into water tank's lid - Filling module with cap - 1/2/3/4/5-way planting modules (hollow version recommended) - Spacer modules (optional) - Internal/external water dispenser modules - Cone module for external water circulation systems - Lid - Custom net pot for Jiffy-7 41 mm grow medium (dry pressed dimensions: diameter 37 mm, thickness: 7.5 mm) - Custom net pot with 48 mm internal diameter for other grow medium (rockwool + clay pebbles) - M3 screw points on planting modules for plant tagging and general fixture purposes - Any kind of water pump works with this system - 2" net pots fit into planting ports ### **Dimensions** - Outer diameter of planting modules: 115 mm - Inner diameter of planting modules: 107 mm - Planting module height: 120 mm - Spacer module heights: 40/80/120 mm - Wall thickness: 4 mm - Clear inner diameter of pot trays: 53.5 mm - Outer diameter of pot trays: 65 mm - Compatible silicone hose: ID 10 mm fixed, OD 18 mm (max), - Temperature sensor mounts in the filling module (10k thermistor): 5 mm cylindrical shell diameter. ### **Printing recommendations** - 20% infill - No support - 215x215 mm printing area required - Use wide brims whenever the surface touching the bed is small (filling module, hollow planting modules) ### **Recommended parts** Water pump: 10 mm outlet: https://www.aliexpress.com/item/4000422969945.html ~~19 mm outlet (tube adapter needed): https://www.aliexpress.com/item/32804709012.html~~ ID=10 mm / OD=13 mm silicone tube for the internal dispenser module: https://www.aliexpress.com/item/1005001986349236.html ID=18 mm / OD=24 mm silicone tube for the water pump adapter if 19 mm water pump is used: https://www.aliexpress.com/item/32742367454.html Nutrient water reservoir: https://www.ebay.co.uk/itm/Plastic-barrel-with-screw-cap-for-Fermentation-or-food-storage-from-10-to-65L/265078964674 I'm using a 20L variant but anywhere over this volume works. 30L has seemingly large enough screw cap to fit and glue the module adapter into it. 20L is a borderline case. ### **Watering schedule** Last year I started with 30 minutes on and 30 minutes off. My current schedule is 5 minutes on and 20 minutes off. You can further shorten the on-time and lengthen the off-time if power saving is a requirement. Let the roots of the plants be completely wet (should take a few minutes at least) and start the water pump again when they start to dry out (up to 1 hour). If you don't have a timer then continuous water circulation is also a possibility. ### **DIY fertilizer** ~~https://boundarycondition.home.blog/2020/06/14/making-stinging-nettle-fertilizer-and-parasite-repellent/~~ Unfortunately this fertilizer doesn't work with hydroponic systems. ### **STEP design files** https://mega.nz/file/rAsgmJxI#8zjWuJnWmw-kGbBgjJpBxMaNEADc7xj7KLWQm9FMx1I ### **Changelog** - **2019.02.16** Filling module update: temperature sensor mounts strengthened - **2019.02.25** 1/2/3-Way planting module update: hexagonal hole replaced with cylindrical hole in which M3 screw fits. - **2019.03.24** Added alternative 1/2/3-Way planting modules without bottom (tube guiding ring is still there). Roots could clog the little holes in the original version. If you are concerned with this issue use the "hollow' version. - **2019.03.31** Added **Blank_Cap.STL**. [OtherRyn](https://www.thingiverse.com/OtherRyn/about) suggested to cover plant nodes if not in use. Thanks for the idea! Added new pots with different cutout pattern. - **2019.04.03** Added **Filling_Module_Cut.STL**. A 12 mm wide cut is placed at the bottom so you can route wiring easily if connectors don't pass through the 3 small tubes. - **2019.04.30** Added **Filtration_Mesh_Holder_01/02.STL**. Use one of the holder as a template and cut out its outer contour from a mesh material. Cut out a ~23mm diameter center hole from the mesh. Sandwich the mesh between the holders, punch the screws through the mesh and tighten them. Use stainless steel screws/nuts/washers! Once assembled drop it into one of the Module Spacers. There's no fixture, the whole thing should sit tight due to gravity. Place it below the filling module to catch debris. - **2019.05.31** Added **Stream_Breaker.STL**. Attach this element onto the dispenser module's cup if the water stream is too strong. The friction should fix the 3 legs in place. - **2019.06.05** Added **Lid_Without_Holes.STL**. To prevent algae growth on the top of the system use this version. Air ventilation should be still good due to the air gaps between planting modules. - **2019.09.26** IKEA Muskot Pot 7 1/2" adapter modified (inner diameter increased from 232mm to 240mm) and a single-part version is uploaded for larger printer beds. If you had a tight-fit issue with it before, replace with this modified part. - **2020.04.19** Added 4/5-way planting modules (hollow) and shortened pots that fit them. 5-way module has its mounting points moved up near the top. - **2020.06.17** Added 2 new adapters for the following planting pots: https://www.ikea.com/nl/en/p/oestlig-plant-pot-in-outdoor-red-brown-50384864/ OESTLIG_Plant_Pot_12_12_Adapter.STL 32 cm (12 1/2") outer diameter, 30 cm (11 3/4") inner diameter, 32 cm (12 1/2") height and link not working: https://www.ikea.com/us/en/p/oestlig-plant-pot-indoor-outdoor-red-brown-00384866/ OESTLIG_Plant_Pot_14_12x14_12_Adapter.STL 37 cm x 37 cm (14 1/2" x 14 1/2") rectangular plant pot - **2021.04.06** Due to confusion and request the M3 screw points are removed from 1-2-3-4-5-Way Hollow Planting Modules. Both version remain uploaded. The hollow planting modules are recommended over the strainer bottom version. - **2021.05.03** Added a new adapter for the following planting pot: https://www.ikea.com/nl/nl/p/ostlig-sierpot-binnen-buiten-roodbruin-20384865/ OESTLIG_Plant_Pot_13_12_Adapter.STL 34 cm (13 1/2") outer diameter, 32 cm (12 1/2") inner diameter, 50 cm (19 3/4") height - **2021.05.14** Added a new adapter for 4 inch PVC pipe: Module_Adapter_4_inch_PVC_Pipe.STL - **2021.05.31** Added a new adapter for the following planting pot: https://www.ikea.com/us/en/p/persillade-plant-pot-dark-gray-10346765/ PERSILLADE_Plant_Pot_9_12_Adapter.STL 28 cm (11") outer diameter, 24 cm (9 1/2") inner diameter, 27 cm (10 3/4") height - **2021.06.21** Added new adapter for the following rolling planting pot: https://www.ikea.com/us/en/p/ikea-ps-fejoe-self-watering-plant-pot-white-20039394/ IKEA_PS_FEJO_Plant_Pot_15_14_Adapter.STL 39 cm (15 1/4") outer diameter, 35 cm (13 3/4") inner diameter, 35 cm (13 3/4") height - **2021.06.27** Previous adapter modified due to slightly larger pot than advertised: IKEA_PS_FEJO_Plant_Pot_15_34_Adapter.STL 40 cm (15 3/4") outer diameter, 35 cm (13 3/4") inner diameter, 35 cm (13 3/4") height - **2021.09.13** Added a new kind of module adapter with tabs to screw down to lid: Module_Adapter_With_Tabs.STL - **2021.11.05** Enlarged wall thickness of Dispenser_Module_Internal.STL from 1.7 mm to 2.0 mm.
