    Do you know if your leafy greens are receiving enough light? It is important that plants receive their specific desired amount of light everyday for optimal growth. Daily light integral (DLI) is a measurement used to understand the quantity of light plants receive throughout the day. If you are curious how many photosynthetically…

  “We’re aiming to gain efficiency of production in the greenhouse, and we’re looking to have better yields and quality of production, all while lowering the consumption of energy,” says Louis Golaz with RED Horticulture. “That makes us much more than just a lighting manufacturer.” Together with new sales manager Jose Carretero, he explains why…

28 – The Bible of Lighting – by Hort Americas.pdf

  High-pressure sodium (HPS) lighting was long considered the industry standard when it came to lighting indoor and greenhouse controlled environment agriculture (CEA) applications. So ubiquitous was the usage of HPS that many greenhouse and indoor setups were designed specifically to accommodate the lighting system, accounting for the radiant heat generated by HPS bulbs and…

“There seems to be some debate,” Colin Clark, CropKing “There seems to be some debate about whether plants will grow better under 24hrs of light, and today we’re breaking down our thoughts,” says Colin Clark, Technical Horticulturist at CropKing. “To better understand this topic we need to know some basics about photosynthesis. As many know…
