Aquaponics A small, portable aquaponics system. The term aquaponics is a blend of the terms aquaculture and hydroponic agriculture. Aquaponics (/ˈækwəˈpɒnɪks/) refers to any system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised can accumulate in the water, increasing toxicity. In an aquaponic system, water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrifying bacteria initially into nitrites and subsequently into nitrates that are utilized by the plants as nutrients. Then, the water is recirculated back to the aquaculture system. History Woodcut from the 13th century Chinese agricultural manual Wang Zhen's Book on Farming (王禎農書) showing rice grown in a floating raft planter system (架田, lit "framed paddy") in a pond Live components
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.

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.

DWC (Deep Water Culture) Questions and Answers - Just For Growers Hydroponics, in its purest form, is also referred to as Deep Water Culture or DWC for short. No substrate growing media is required. The plants' roots literally dangle straight into water. Now, for those of you who have been continually warned about over-watering plants, this may seem a little odd. Surely permanently submerging roots in water is a bad thing for all but aquatic plants, right? What is DWC / Water Culture? DWC is the practice of growing plants in aerated water. Single vs. Single stand-alone systems are fairly cheap to buy and even more popular for DIY enthusiasts. However, get it right and the growth rates and yields possible are astounding. Roots exploding out of a net pot, lifted out of this DWC hydroponics system just a few weeks after installation. Q: What types of nutrients and additives work in DWC? A: Mineral based nutrients. Q: Can I use beneficial biology in DWC systems? A: This question divides DWC growers. Keep EC / TDS on the low side. A: 62-68°F (17-20°C).
NO ALLA DISCARICA DI AMIANTO! NO AL POLO LOGISTICO! hydroponic lettuce garden from plastic bottles (Grow bottles) I have no land to grow a garden, But I do have windows that get plenty of sunlight. I wanted a compact, low maintenance way of quickly growing lettuce and other small, fast growing plants. My goals were: cheap: I'm not looking to spend much money on this project, so cheap is good, and free is better. It's easy: No expensive tools or equipment, no expertise, just scissors, and an "exacto knife" or other sharp pointed blade. low maintenance. no electricity: There are no air or water pumps. The materials are easy to find: anybody, anywhere can find the materials for this project. It works: So far it's been working great. the plants are healthy and are growing quickly. It's compact. the smaller bottles take up about 3 inches of a windowsill, and the larger (2 liter) bottles take up only 5 inches, so you can fit several in a window.
GENERAL HYDROPONICS: pH Dynamics And Adjustment Answer: pH is the measure of acidity/alkalinity of a solution. Answer: Specifically, pH is a measure of the hydronium ion H3O+. It is based on a logarithmic scale from 0 to 14. "Pure" water has a pH of 7.0. If the pH is less than 7, the solution is acid. Answer: The ideal pH range for most hydroponic crops is between 5.5 and 6.5. Answer: pH is important because it affects availability and absorption of several of the 16 atomic elements needed for plant growth. Answer: pH is adjusted by using an acid to lower it or an alkali to raise it. Answer: Short-term solutions include citric acid (which degrades in solution) or sulfuric acid made for car batteries. Answer: When first starting out it is a good idea to measure the pH of your water every day, until you get a feel for your system. Answer: Start out with one milliliter per gallon. Answer: The easiest way is to continue adding pH Up.
