Understanding Hydroponics This instructable will explain household hydroponics, with the intention of growing edible flora. In layman's terms, hydroponics is the science of growing plants without soil-- although the plants may or may not be suspended in a solid medium such as gravel, or expanded clay balls. Soil retains minerals and nutrients, which "feed" flora, as we all know. Why eliminate the soil? Growing your own food can be a rewarding experience. That being said, there may be more efficient systems out there for the home grower. Make A Cheap &Easy Solar USB Charger With An Altoids Tin : TreeHugger - StumbleUpon Photos by Joshua Zimmerman The craftster behind the very popular $3 solar-powered emergency radio is back with a new awesome project: a cheap solar battery charger with a USB plug. Zimmerman wrote, saying that he saw a lot of small solar powered chargers being talked about over Earth Day, but there was a big problem: "They're all quite nice, but also quite expensive. I don't think I've seen any for less than $60, and I've not seen one that really suits my style." So, he came up with his own, using one of our favorite reusable items -- the ever wonderful Altoids tin. In looking for the cheapest way to accomplish the task, Zimmerman found that he could build a USB solar charger for under $30 (or $10 if be buys parts in bulk, though it's not likely you'll be buying bulk solar cells and DC-to-USB converter circuits). Zimmerman states, "The central brain of our project is a DC to USB converter circuit.
Growing With Hydroponics & Aquaponics Scoprire lAcquaponica Domestica. Come Realizzare in Casa un Impianto per la Coltivazione Acquaponica. Soluzioni Possibili ma Soprattutto Low Cost! Se qui sei nuovo ISCRIVITI alle News RSS feed. Thanks for visiting! di Gaetano Benanti Da sempre mi sono interessato ai metodi di produzione di cibo non convenzionali, da buon appassionato di fantascienza il termine “coltura idroponica“ mi è sempre stato familiare, l’idea di una piccola serra a casa in cui coltivare le mie verdure tutto l’anno, senza utilizzare la madre terra come strato su cui far crescere le mie piantine, mi ha sempre intrigato e così ho fatto pure qualche piccolo esperimento e modestamente devo dire con discreti risultati. Trovando interessante l’argomento delle coltivazioni idroponiche o indoor, ho sempre frequentato siti e blog inerenti all’argomento, con il passare del tempo mi sono reso conto che questo metodo di coltivazione è tutt’altro che un giocattolo fantascientifico ma anzi un valido strumento di sviluppo economico e tecnologico.

Solar Powered Vertical Aquaponics System SOLAR POWERED VERTICAL AQUAPONICS SYSTEM: This is an original design I made to maximize the yield of a 12′x12′ foot space and use gravity to minimize the energy used for irrigation and nutrient delivery. The system is a vertical spiral aquaponics growing system powered by a single 250 watt solar panel and a small DC water pump/filter system. A single DC pump makes the whole thing work. The tower is 15′ tall at the top of the solar panel and approximately 13′ at the top spiral. The water from the tank is pumped up through a small PVC pipe to flow slowly down through the plant crops growing in the spiral growing tray. Upon harvest, water flow is increased, the harvest gate at the bottom end of the spiral is removed and the crops flow down the spiral making harvesting easy. The growing bed tray is approximately 360′ feet long by 3 feet wide, creating a grow area of approx. 1080 square feet. Cost to build this system is about $5k including tank, materials, pipe, pump, and solar power system.
NO ALLA DISCARICA DI AMIANTO! NO AL POLO LOGISTICO! Hydroponics Reader Brandon Koots is a 15-year-old student from Curacao who's been growing his own food for over 4 years. He runs a site where he talks about hydroponics and gardening, and he shared some great tips on starting a simple hydroponics system, called a "raft system." Build a simple raft system in just a few minutes Hydroponics is an easy way to grow your own food. A raft system is a hydroponics system where the plants grow in a medium and their roots hang in the water. In a hydroponic system you can plant more food than in the same area of soil. Materials: a knife or drilla plastic bin (size doesn’t matter)some plastic cupsa markera ruleran oxygen pump - choose one that comes with an airstone Here are the steps: 1. 2. 3. 4. 5. 6. You can also use your raft system as an aquaponic system The only extra supplies you'll need are fish and fish food. reduces work that has to be done in a gardenhelps you to save more waterrequires less space.

Attrezzi di lavoro: la ciclofficina in casa In casa, con poco spazio, si può allestire una ciclofficina essenziale per poter intervenire sulla maggior parte dei componenti della bicicletta. Bastano un po' di attrezzi e una manciata di accessori. Cavalletto Un piccolo cavalletto per la casa può essere sufficiente, altrimenti bisognerà, per molte operazioni, ribaltare la bicicletta sottosopra poggiandola per terra. Chiavi a brugola Dimensioni utili: 2 mm 2,5 mm 3 mm 4 mm 5 mm 6 mm Pompa In casa si può tenere una pompa più grande per un gonfiaggio più rapido della camera d'aria, ma l'ideale sarebbe disporre di una pompa con manometro. Chiavi composte Dimensioni utili da 8 mm a 17 mm. Cacciaviti Almeno uno spaccato e uno a croce, meglio se di più dimensioni. Tiraraggi Per regolare i raggi o sostituirli. Smagliacatena Serve per interventi sulla catena e deve essere del tipo adatto alla catena usata. Leve per copertoni A casa è bene averne di tipo resistente, magari anche in metallo, per aiutarsi nell'estrazione dei copertoni. Kit per forature
