What is VPD?

VPD, the abbreviation of Vapor Pressure Deficit, is the difference between moisture present in the air and the potential for your indoor environment to hold more moisture. VPD is important because it directly relates to our plant’s transpiration rates. It can be used to fine-tune water flow through the plant. This gives growers an additional ‘control knob’ to balance the environment for optimal plant growth and proliferation.

What temperature and relative humidity should I target?

The key to success in any growing plant is understanding the lifecycle of the plant. This is also true with growing cannabis. There are seven periods of cannabis, all requiring different temperature and relative humidity levels. The following is a list of proper temperature and humidity in every stage.

Vegetative room - Temperature: 80℉, Relative humidity: 70%

Flowering room - Temperature: 70-80℉, Relative humidity: 40-60%

Mother room - Temperature: 75℉, Relative humidity: 60%

Clone room - Temperature: 80℉, Relative humidity: 90%

How do I know my plant got Bud Rot?

Bud rot or gray mold is a botanical fungal disease. It comes from a fungus known as Botrytis Cinerea, a necrotrophic fungus affecting many plant species. When the environmental conditions become conducive, the mold rapidly rots the buds, leaves, and stems. So prevention is much more important than treatment. Here is a list of 7 tips to help you prevent bud rot.

1. Inspect and assess your plants daily

2. Isolating infected areas of plants

3. Wearing protective gear before moving to grow room

4. Sanitize all gardening equipment

5. Inspect humidity and ensure adequate air circulate

6. Choose to grow mold-resistant cannabis plants

7. Spray fungicides at the flowering stage (Not recommend)

Altaqua hvac systems VS air conditioners

For our product, the most obvious difference with air conditioners is that our products can achieve year-round free cooling, heating and dehumidification.

What is Relative Humidity?

Relative humidity, or RH, is a ratio of the amount of water vapor present in the air to the amount of water vapor the air could potentially contain at a given temperature. In other words, RH changes with the temperature changes as cold air cannot hold as much water vapor as warm air can. Properly managing the RH in your grow room is key to optimizing your yield and hence maximizing your profit.

Altaqua hvac systems VS chillers?

Our products (GA-series) combines dehumidifying and air conditioning into one integral unit.

What is Dew Point?

The dew point is the temperature at which air needs to be cooled to constant pressure to attain a relative humidity (RH) of 100% when air cannot hold more water in the gas form. If the air is cooled even more, water vapor will come out of the atmosphere in liquid form. That means if the dew point rises, there will be more moisture in the air.

What if using with grow light, CO₂ producuer and other equipment?

We use PLC, if needed, we can tailore programs of optional function in our machine. Achieve above functions by controling valves with PLC

How to solve the maintenance problem of the equipment?

During the warranty, if there is a problem with any parts, they can be replaced free of charge.
