Ventilation of the growroom

The proper ventilation is essential to avoid accumulation of heat and humidity common in indoor cultivation.
But as it made a good ventilation system?
Above all from an extractor adequate to the volume of your growroom, bearing in mind that the scope will have to allow the extraction of all the air in 5 minutes.
You do the math yourself or contact a specialist store for selection.
Make sure you have all the information necessary to help those responsible to advise the best product for you: room volume, length and diameter of the ventilation tubes, presence or absence of filters, supported by the wattage of your system.

Remember also that in calculating the space to prevent condensation and subsequent damage the extractor should be mounted vertically, parallel to the wall.

The ' puller , as the name suggests, will allow the exhaust air outlet. So we must equip ourselves with a tool to enter fresh air, or a fan .
The extractor fan will have the same capacity and ensure a proper recirculation.
To exploit the full potential of our system should be paid particular attention to the diameter of the pipe , which is perfectly compatible with the extractor fan and no losses. Do not go also positioned objects in the immediate vicinity of the latter, to avoid that the flow of air is interrupted.

The tubes that carry air to the diameter should be chosen to suit your equipment, shall be as short as possible and use if they are required, fittings and never Y T.
There are on the market of soundproofing to limit the noise of turbulence.

To move the air within the growroom outside the guaranteed flow from extractor and fan you can resort to a fan oscillating, that creates a gentle breeze.
This will ensure the elimination of so-called hot spots, the stagnation points of the heat and humidity, and a good distribution of carbon dioxide (CO2).

As a general rule, the extractor will be positioned at the top at one end of the room, while the fan will be from the opposite side, at the bottom. The fan will blow in the same direction as the incoming air. To ensure the efficiency of your system will be necessary to measure temperature and humidity at various times (lights on / off) at different points in the room.

The monitoring occurs through the thermometer and the hygrometer , which will positioned at the point of higher moisture and with the highest temperature (between the leaves and close to the lights, for example).
Tools with a point of minimum and maximum memory provide the best control.
Sensors and instruments should not be placed in direct contact with sources of heat or wet surfaces.

Maintain the optimal values will be more simple with a number of plants moderate.

To automate the ventilation must provide themselves with a humidistat and thermostat , also be placed in the most warm / humid in the growroom.
During the hours of light they will trigger the ventilation when the temperature will reach 27 degrees or the humidity will rise up to 70%.
If the weather is consistently hot and humid it may be necessary to leave the fan is always engaged with the sole control of a timer.

Nevertheless, if the temperature was still high, you can try moving the hours of artificial light at night, do not add up to the high temperatures of the day with those lamps.
If you can replace the bulbs with models fluorescent , and if the weather is still bearable to reduce the hours of light.
As last dotatevi an air conditioner.
And if it was too cold? Try turning the fan input less often, especially at night, or taken from another room the air rather than directly from the outside. Also here is the last chance to pre-heat the air.

The ventilation system can be complex both from designing that to assemble, and the components may have high prices. The expert advice in these cases is strongly recommended.
