Water purity in Hydroponics

Town water is generally suitable for Hydroponics, but if you are using bore water, spring water, dam water or rain water, you may have to check to see if this is suitable.
What problems could occur, is the salt content of the water, may be too high, the zinc content from metal (zincalume) tanks, could make it toxic for plants (even though it may be still safe for us to drink), as well as any number of chemicals, poisons or fertilizers, could be contaminating the water supply. Please speak to a Hydroponic Company about the water supply if you are unsure. More >

Temperature and Fresh air in Hydroponics

Temperature and Fresh air in Hydroponics

Optimum temperature depends on the plants. Generally, Phosphorus up-take is severely impeded below 15 degrees Celsius, so that’s our bottom temperature. It is recommended to heat the nutrient if it is below 15 degrees Celsius for more than 4 hours per day. Maximum temperatures are, (as a guide) around 30 degrees Celsius but as long as it is well below the temperature where humans start to sweat the plants should be all right. Use common sense. If the plants are in 20-25 degree temperatures and 40-60% humidity, then it is likely that you would feel comfortable where the plants are.

Nutrient Ph in Hydroponics

pH is the level of acidity or alkalinity of the nutrient solution. Think of it as sweet and sour. Most nutrients in town water will be within the range of 6 to 6.5 pH. ALL PLANTS GROW IN THIS RANGE IN HYDROPONICS. Anyone who tells you otherwise, is either horticulturally trained in soil only or is reading materials drawn from soil based research and is therefore untrained for plant nutrition in Hydroponics.

Nutrient Strenght in Hydroponics

Nutrient Strenght in Hydroponics

Assuming you have a commercial brand of nutrient made by a good Australian company such as Accent Hydroponics, Growth Technology or the like, you will get excellent consistency in the nutrient. Always use a 2 part A&B style nutrient where possible. Nutrients must be solely designed for Hydroponics. Soil fertilizers require bacteria to break down more complex elements into useful ones. They are likely to be less soluble, not pH adjusted, and are usually too slow to release the necessary elements to be suitable for Hydroponic systems. Plants may grow for a little while in Hydroponics using soil fertilizers but they generally exhibit minor mineral deficiencies, then develop major deficiencies, until even changing to a Hydroponic nutrient can not correct the disorders. Soil fertilizers normally kill hydroponically grown plants, but not overnight. Certainly they will never produce as nature intended them to if you do not supply the right amount of minerals in a soluble form.

Oxygen to Nutrient Ratio in Hydroponics

Oxygen to Nutrient Ratio in Hydroponics
Oxygen keeps a plant’s roots healthy and allows the plant to take up nutrient. Oxygen is the key to growth rate. Without oxygen around the roots, the roots will rot and die. You cannot grow in water, unless you dissolve oxygen in it. The recommendation is that you do not grow in water, just feed enough nutrients to keep the roots moist, with access to oxygen. The 5 systems I have described in this book will have varying degrees of oxygen according to their design. The oxygen level or the oxygen to nutrient ratio is the key to success.
RULE: PLANTS CANNOT TAKE UP THEIR NUTRIENTS UNLESS OXYGEN IS PRESENT. THE MORE OXYGEN, THE FASTER THE UPTAKE OF NUTRIENT.

Light in Hyroponics

Light in Hyroponics
Light is the energy that creates life. Life cannot exist without it, and cannot thrive without enough of it. Plants process up to 5,000 foot-candles of light intensity to get the energy to grow. The sun is around 1,000,000 foot-candles. Shade can be lower than 1,000 foot-candles.
Plants will enjoy much light, but some do not like all the heat put out by sunlight. Shade cloth is ideal for hot conditions, also to keep plants from, insects, wind, rain and other damage, but rarely is the requirement for low light levels.

Hydroponics The Basics

Hydroponics The Basics

The most important thing for you is to realize is that Hydroponics should be easy. It is easier for the home grower to grow hydroponically than in soil and that’s a fact! This is the reason for this booklet. In this booklet I hope to show you how easy, how inexpensive, and how satisfying Hydroponics is. Simply there is no easier way to grow, house plants, ornamental plants, vegetables such as tomatoes, lettuce, beans, fruit, root crops such as potatoes, carrots, onions, flowers such as roses and carnations, bulbs, vines, trees, orchids, herbs, anything in Hydroponics. To my knowledge, there is nothing that is grown that cannot be grown using hydroponic techniques.

Aplicatii ale sistemelor Hidroponice

Hidroponia are si alte aplicatii, in particular in domeniul gradinaritului outdoor si indoor (in casa si afara din casa). In Statele Unite, in ultimii 25 de ani in special, diversi producatori au dezvoltat si oferit publicului unitati mici pentru gradinaritul hobby, care folosesc tehnologii identice cu cele folosite cultivatorii comerciali. Aceste sisteme mici sunt concepute pentru publicul larg, si pot fi instalate in balcon, in hol, in bucatarie sau in camera de zi. Exista micro-sisteme pentru o singura planta, care incap chiar si in cele mai mici locuri.

Sunt produsele Hidroponice ECO ?

Sunt produsele hidroponice produse organice (ECO)? Raspunsul scurt ar fi nu, nu sunt. Simplul fapt ca nu foloseste solul ca substrat de crestere interzice din start apelativul “organic”. Cat despre fertilizatori, pana la ora actuala nu exista un fertilizator complet organic pentru hidroponie. Dar in mod sigur exista pe piata fertilizatori atat de bine formulati incat nu depoziteaza nici un reziduu toxic sau vreun metal greu in plante, si nu afecteaza in nici un mod negativ fiziologia plantei daca sunt folosite corect.

Dejavantajele sistemelor Hidroponice

Dejavantajele sistemelor Hidroponice
• Se poate folosi metoda hidroponica pentru cultura de masa a unor produse de slaba calitate – cum ar fi rosii care nu au gust, sau trandafiri care nu au miros. Aceste rezultate sunt cauzate nu de metoda in sine, ci de incercarea unora de a economisi acolo unde nu este cazul, pentru a scoate profituri mai mari. Hidroponia folosita corect duce la obtinerea de alimente cu cel mai inalt continut nutritiv, pline de gust si de aroma
