It is a value calculated according to the specifications / characteristics of the heating system. This is a max value which means that for example the boiler can not provide more that this. For example for a greenhouse of 10000m2 (1ha) if this value is 120W/m2, and the combinded efficiency of the boiler + distribution system is 85%, the max heating power can be provided by the boiler is 120*10000/85% = 1.41MW. This is a simple example without any heat storage. If we have a heat storage, which is very common, then the max heating power from the boiler can be different than 1.41MW.
Heating capacity depends strongly from the area. There are areas where there are small heating needs and then this value can be even less than 50W/m2 and areas with high needs, this value can be even higher than 200W/m2.""" ;

For the first related to CO2 source, we have mainly two sources, either pure CO2 stored in special tanks or CO2 which is obtained from exhaust gas (we use also the term flue gas) which is emitted as a result of the combustion of fuels such as natural gas.   

In general, CO2 enrichment decreases the oxygen inhibition of photosynthesis and increases the net photosynthesis in plants. This is the basis for increased growth rates caused by CO2 at low as well as at high light levels. Elevated CO2 concentrations also increase the optimal temperature for growth. Pot plants, cut flowers, vegetables and forest plants show very positive effects from CO2 enrichment by increased dry weight, plant height, number of leaves and lateral branching. Plant quality expressed by growth habit and number of flowers is often enhanced by CO2 enrichment. The rooting of cuttings is often stimulated by high CO2 levels.""" ;

The greenhouse construction is therefore handled under strict supervision by a professional supervisor. Supervisors are experienced Dutch greenhouse builders who accompany local subcontractors on each step of the assembling process.

Belangrijk voordeel van deze keuze is dat het een algemeen bruikbare definitie is zonder dat er aannames worden gemaakt over de constructie van de kas. Voor de meeste gevallen zal een block een gewone rechthoek vormen, waardoor het referentiepunt in het midden van het block terecht komt. Voor een block dat geen rechthoek vormt kan het zijn dat het referentiepunt buiten het block terecht komt, omdat de X en Y-coordinaat bepaald wordt door de langste lengte en langste breedte van het block. Dat vormt echter geen probleem, omdat het referentiepunt een virtueel punt is, waarmee gerekend kan worden ongeacht de specifieke, absolute locatie."""@nl ;

Warm air has a higher moisture-holding capacity than cooler air; therefore as the temperature of air increases, the relative humidity decreases even though the amount of water remains constant. Air at 70° F will hold twice as much moisture as air at 50°F. In the range of temperatures encountered in a greenhouse, for every 20° F rise in dry bulb temperature, the water-holding capacity of the air doubles, and the relative humidity is reduced by one-half.

CO defines a trait as a character of an individual plant or of a group of plants that can be
observed and that results from the expression of its genes and their interaction with the
environment. This trait definition can be summarized by “what is observed”. Examples of traits
are “plant height’, “pod color”, “grain yield”, “seed germination rate”, “plant flowering time”,
“panicle shape”, “plant resistance to blight”, etc.
Traits can be formalized by a meaningful combination of entities and attributes. The entity
is the observed plant part. The entity can be defined at the level of the cell, the tissue, the
organ, the whole organism or the sub-product of the crop. The attribute is the feature of an
entity. Attributes can be states or processes. Examples of states are weight, length, area,
color, chemical content, while examples of processes are vegetative period duration,
photosynthesis rate, senescence rate.
A direct consequence of the trait decomposition into entity and attribute is that two traits that
share the same combination of attributes are identical even though they are named differently.
Thus, decomposing a trait into entity/attribute is a good practice to prevent trait duplication.
Table 3 shows examples of trait breakdown into entity/attribute.
A trait can be described by a general entity or as a specimen, something that obviously belongs
to an entity but is noticed by reason of an individual distinguishing characteristic. Examples of
specimen are primary branch, first flower, first grade commercial fruit, flag leaf, third leaf, main
stem, fertile stem, mature fruit, immature fruit.""" ;

Once air becomes saturated, water will condense out to form clouds, dew or films of water over leaves. It is this last instance that makes VPD important for greenhouse regulation. If a film of water forms on a plant leaf, it becomes far more susceptible to rot. On the other hand, as the VPD increases, the plant needs to draw more water from its roots. In the case of cuttings, the plant may dry out and die. For this reason the ideal range for VPD in a greenhouse is from 0.45 kPa to 1.25 kPa, ideally sitting at around 0.85 kPa. As a general rule, most plants grow well at VPDs of between 0.8 and 0.95 kPa." ;
