Multi-tunnel greenhouses, a good treatment in ecological
Life in ecology is more complicated due to treatment limitations and the multitunnel becomes a key alternative, capable of extending the life of a California pepper for four more weeks. Organic crops have fewer tools to control their diseases and the pest population and the greenhouse becomes a basic active…

What is an intelligent greenhouse?
An intelligent greenhouse has the ability to control the environmental variables that affect the crop. We list the main systems controlled in an intelligent greenhouse: Climate control There are installed two weather stations, one inside to control the climatic parameters of the cultivation, and another one on the outside to…

What are fertilizers and how to use for irrigation
Fertilizers are the minerals elements that we incorporate to the irrigation water, once dissolved, what we get is the nutrient solution. To make this nutrient solution water chemistry must be taken into account for subtracting the nutrients already present in composition, since once dissolved salts, (dissociated) there is no way…

Recommendations for correct Trellising Plants: Handset Hangers
Reasons to use Handest Hangers As the plant grows it is rolling in the opposite direction to clockwise, until it reaches the wire grid. Once the plant has reached the grid, there is no growing chance of the plant to ensure correct formation of this and its fruits, so the…

How to Manage Heat in Greenhouses
Direct combustion One of the dispensing systems using CO2 combustion gases are hot air generators with direct combustion (combustion gases remain inside the greenhouse). The generators are low power (50-100 kW thermal) and they are distributed along the greenhouse surface according to CO2 production or as heat required. For this…

Carbonic enrichment systems in Greenhouses
Two sources of CO2 are used in greenhouses to conduct carbon fertilization: The first comes from the use of flue gas (LPG and natural gas) generated in the same holding. The second uses pure liquefied gas obtained from industrial processes (fermentation, production of fertilizers, etc.). Gases from industrial processes The…

Carbonic Fertilization Levels in Greenhouses
The CO2 concentration in the atmosphere is quite constant and it is around 300-400 ppm, plants perform the process of photosynthesis under appropriate lighting (energy for reaction) and environmental (reaction reagents: CO2 and water level) conditions and by fixing this carbon dioxide and generating sugars or similar processes employed in…
