Collaborate Disseminate
Science fiction movies often portray horticulture in the future, be it terrestrial or aboard spacecraft, with hydroponic gardens overflowing with leafy greens and brightly colored fruit. There is no soil, just clear water that hints at future-people creating a utopia of plant strains untethered from their earthly roots.
This star-faring …read more
Microgreens, also known as vegetable confetti, are all the rage in fancy restaurants around the globe. Raised from a variety of different vegetable seeds, they’re harvested just past the sprout period, but before they would qualify as baby greens – usually 10-14 days after planting. There’s a variety of ways to grow microgreens, and [Mr Ben] has developed a 3D printed rig to help.
The rig consists of two parts – a seed tray and a water tray underneath. The seed tray consists of a grid to house the broccoli seeds to be grown, with small holes in each grid …read more

[Todd Christell] grows tomatoes in hydroponic buckets in his backyard, and recently he suffered a crop loss when a mechanical timer failed to dispense the nutrient flow as directed. He decided the solution was to add a sensor array to his home network.
[Todd]’s home automation setup runs on a Raspberry Pi loaded with Jessie OS and Node-Red, with Mosquitto as his MQTT message broker. With a sensor network in place, [Todd] would get updates on his phone alerting him if there was a problem with the pumps or if the nutrient bath was getting too low.
The proposed hydroponic …read more

Hydroponics is an effective way of growing plants indoors through the use of water medium and artificial lighting. It often involves having a system to raise and lower the water level around the plants to let the roots breathe, however this can require some non-trivial plumbing. [Peter] wanted to instead explore the realm of wheel hydroponics to grow some ingredients for salad.
The idea is to have pods mounted on a rotating assembly, similar to the carriages on a Ferris Wheel. By rotating the wheel slowly, each pod spends a certain amount of time submerged, and a certain amount of …read more

When operating any kind of hydroponic farming, there are a number of lighting solutions — few of them inexpensive. Originally looking for an alternative to the lighting of IKEA’s expensive hydroponics system, [Professor Fartsparkle] and their colleague prototyped a rail system that allows clip-on LED boards for variable lighting options.
Taking inspiration from wire and track lighting systems, the key was the 5mm fuse holders mounted on the bottom of the LED boards. Snipping off their stopping clip makes them easy to install and remove from the mounting rails. The rails themselves double as power conduits for the LED boards, …read more

With winter on the way, our thoughts turn to indoor hacks. And what could be better in the cold winter than fresh veggies? This can be done by replacing the sun with an LED light, and [Margaret Johnson], aka [Bitknitting] has been working on building her own LED plant light.
She’s using a combination of red and blue LEDs that produce the ratio of light frequencies that plants thrive on, and has been experimenting with how bright to make them and how long to run them. This combination of factors determines how much light the plants get every day, called …read more

This team project for the Hackaday Prize is a solution to a rather important problem. Imagine growing plants for use as biomarkers for pollution. It’s a great idea, but how do you grow the plants in the first place? This team is building a space-saving hydroponic system that packs the most green into the least amount of space. It’s simple, and can be built almost entirely with parts from the local home supply store.
The design of this hydroponic system is based on a few PVC pipes, arranged vertically, joined together with a few 90 degree bends. In each course …read more

[Dan Bowen] describes the construction of a backyard hydroponics set-up in an angry third person tirade. While his friends assume more nefarious, breaking, and bad purposes behind [Dan]’s interest in hydroponics; he’d just like some herbs to mix into the occasional pasta sauce.
Feel particularly inspired one day after work, he stopped by the local hardware store and hydroponics supply. He purchases some PVC piping, hoses, fittings, pumps, accessories, and most importantly, a deck box to hide all the ugly stuff from his wife.
The design is pretty neat. He has an open vertical spot that gets a lot of …read more
