Our Canadian team has decades of experience manufacturing high-quality, low- cost products overseas. With our boots-on-the ground and proactive QA&QC approach we are able to take advantage of China’s low-cost, highly skilled workforce while ensuring our products are ethically and responsibly made. This allows us to spend more money on quality control and pass the rest of the savings on to you- the customer.

Our manufacturing partners incredible speed of implementation combined with their extensive research and development team allows us to source and test quality Japanese parts quickly, ensuring our units are always meeting or exceeding the exact specs we require for our customer.

Our first-in-class removable access panels allow for 360° service with our simple plug-and-play replacement parts, which is then guided by our onboard diagnostic screen and helpful technical staff that are available by email and/or phone. Phone Support is limited to Pacific Standard Time 8:00 am-5 pm during business days Monday-Friday.

With decades of experience in this industry specking thousands of rooms, our general recommendation is 50-75 Pints/Day per 1000W of light but that varies based on several conditions.  Unlike other rating systems, we want to see your ideal relative humidity return to set points as quickly as possible after every irrigation event rather than using a vague 24 hour measurement. Nothing makes us happier than helping cultivators dial in to their environment and reap the benefits immediately! We are always happy to jump on a call and help you determine which unit is best for you.

In grow room environments it is best to change the filter every crop, or 3 months.

VPD measures the difference, in terms of pressure, between the water vapor in the air, and the air’s saturation point, which is the maximum amount the air can carry at its current temperature.

Advantages of being able to control your humidity is imperative for VPD.
VPD = Vapor Pressure (saturation) – Vapor Pressure (air)
This pressure difference is what drives transpiration from the plants’ stomata.
Many growers use RH (relative humidity) to measure the humidity level in a greenhouse. This measures the percentage of the air’s water content saturation at a certain temperature. While RH is great for managing humidity, it doesn’t tell us much about the forces driving evaporation from the plants.
VPD, as opposed to RH, correlates with plant transpiration rates, making it a proactive tool for plant empowerment, rather than simply a climate parameter.
If VPD is high, meaning the air is relatively dry, transpiration rates will increase. As the vapor pressure deficit lowers, transpiration will decrease or even stop completely.
More transpiration equals more growth

There are two ways to determine this: 1) by measuring water used per day- knowing that 97% of this moisture will have to be removed from the room with an added buffer of 30%.

2) The other rule of thumb that has been used by many successful growers is to do 50 pints per fixture.

What are the common mistakes you see growers make in the configuration and design of their grow rooms?

1. Thinking bigger is better.
In other words, installing HVAC equipment that is oversized for the heat load. For example, using a 5 tonne AC unit with 8 x 1000 Watt lights; or using LED’s which emit very little heat. In this scenario the AC will cycle on an off frequently causing large temperature swings, which can then cause humidity issues. The blower motor will evaporate all moisture back in the air stream during the off cycle time. The latent load (humidity) will not be removed from the room. Only the sensible heat (measurable temperature) will be removed.

2. Under-sizing Dehumidification
Not contrary to the first rule, what’s important to note here is to properly size your latent load (humidity load). The common calculators are based off of Water in = Water out. This is correct, as your plants transpire 97% of the water. However, we are calculating this over a 12 or 24 hour period. It’s important to know and plan for the late bloom period that requires the plants to transpire at different rates. It is critical to remove the latent load at during and throughout this period. For this reason we always add a 30% increase to the latent load from the water in/water out calculation. It’s also best to use smaller dehumidifiers than one large unit. This will give the room more redundancy, but also keep a better flatline of the humidity levels.
