Light & Plants in the Hydroponic Greenhouses
PAR and Plant Response Curve Just as humans need a balanced diet, plants need balanced, full-spectrum light for good health and optimum growth. The quality of light a plant receives is just as important as the quantity. Plants are sensitive to a similar portion of the spectrum as is the human eye. This portion of […]
Las plantas y la luz en los Invernaderos hidropónicos
RFA y curva de respuesta de las plantas Al igual que los seres humanos necesitamos una alimentación balanceada, las plantas necesitan luz balanceada de espectro total para tener buena salud y un crecimiento óptimo. La calidad de luz que recibe una planta es tan importante como la cantidad. Las plantas son sensibles a una porción […]
אנטי-פוג, אנטי-דריפ, אנטי-מיסט ומה שביניהם
כמה עובדות על מים התעבות: תהליך שבו אדי מים באוויר משנים את מצב צבירתם מגז לנוזל. ההתעבות מתרחשת כאשר אוויר רווי באדים בא במגע עם משטח קר, לדוגמא יריעת חממה. נקודת טַל: הטמפרטורה שבה אדי המים באוויר מגיעים לנקודת רוויה. כשהטמפרטורה ממשיכה לרדת, אדי המים נהפכים לטיפות (טַל). משטח קר הבא במגע עם אוויר רווי […]
Anti-Fog, Anti-Drip, Anti-Condensation and Anti-Mist
SOME FACTS ABOUT WATER Condensation: a process by which H2O vapors in the air are transformed from gas into liquid. Condensation occurs when warmer moist air comes in contact with cold surfaces – greenhouse film in our case. Dew-Point: the temperature to which air must be cooled to become water vapors saturated. When further cooled, […]
You are my sunshine, my only sunshine
Light The main source of light on Earth is the Sun. Sunlight provides the energy that green plants use to create sugars mostly in the form of starches, which release energy into the living things that digest them. This process of photosynthesis provides virtually all the energy used by living things. Light goes through […]

אור
השמש – מקור האור העיקרי על פני כדור הארץ – מספקת את האנרגיה הדרושה לצמחים לתהליך הפוטוסינתזה. קרינת השמש לפי אורכי גל קרינת השמש נחלקת בדרך כלל לשלושה טווחים עיקריים על-פי אורכי גל הנמדדים בננו מטרים (ננומטר שווה לחלק אחד למיליארד של מטר): אולטרה סגול (UV) – בין 100 ננומטר ל-400 ננומטר. קרינה פוטוסינתטית אקטיבית […]
