How the Opticlimate Pro Works

The Opticlimate provides air conditioning for grow rooms, maintaining temperature and humidity levels within optimal ranges during both day and night cycles, regardless of outside temperatures. Inside the unit are 1500w ceramic heaters and a water cooling system. Air is drawn through the Opticlimate's carbon filter panel (at the back of the unit and easily replaceable) via a squirrel cage fan. The air is then treated to match user-defined specifications and expelled through the outlet point (at the front of the unit), where it can then be ducted towards the top of the plant canopy. This process maintains a climate that's tailored to your exact needs. You'll then have complete peace-of-mind that your grow room is always operating optimally, with happier, healthier plants and huge potential increases in yields.

The air conditioning system relies on a supply of cold water from a water inlet point. This means that the Opticlimate has to be plumbed in before use. Installation is relatively straight forward, but the job should be performed by somebody with the appropriate skills, we'll talk you through exactly what needs to be done.

The Opticlimate will also need to be plumbed into a drain, so that hot water can flow from the system after it has been used in the cooling process (the temperature is usually 35-50°C). Users report that this flow of hot water can be utilized very effectively in other areas for purposes like under-floor heating. There is another outlet on the Opticlimate for water produced by the through dehumidification process, but in this case, we recommend using it to fill your reservoir tank. A float-valve activated lifting pump is available separately which will redistribute this water to other areas if required.

The Opticlimate comes with a tethered controller unit which is used to program ideal daytime and night-time temperature and humidity levels. 'Preheat' and 'slow cool-down' functions can be set up to gradually ease plants into day and night cycles. This is particularly useful when moving from night (18°C) to day (25°C). As lights switch on, it takes a little while for the temperature of plant matter to reach an equilibrium with the room. During this period, the cool outer edges of fruits and leaves make contact with warm air. When warm air hits cold surfaces, condensation forms, and this causes big problems! Moisture sets into delicate areas, triggering botrytis (rot), which can devastate entire crops. The Opticlimate massively reduces the risk of this ever happening.

Three sensors take readings from the grow area – a temperature probe, a humidistat and a light sensor (which is built into the humidistat). The information is gathered by the Opticlimate's on-board computer and used to make changes, so that the air that's expelled from the system always matches the specifications programmed into the controller. The controller itself has a clear display and is very easy to use - comprehensive instructions are included in the manual. You can input ideal temperature and humidity levels for both day and night cycles and the light sensor will make sure that the Opticlimate switches to the correct settings automatically, though you can program the timings manually if required. Either way, the Opti has it covered!

There is a rectangular carbon filter on the air intake at the back of the unit, but this shouldn't be used as your only form of odour control. The Opticlimate is a complete climate control solution, but it was not designed to be the primary method of dealing with unwanted smells, even though its filter will reduce the problem considerably. Instead, we recommend using a small (standard cylinder shaped) carbon filter and duct fan to move air out of the room or tent. This will maintain negative pressure and ensure that odours stay within the grow area. Because the extraction system required for a relatively large set-up (of up to 6 x 600w HID lights) is much smaller when using the Opticlimate, this helps to reduce the sound generated by fans. The unit itself runs at very low noise levels, ensuring that the grow area is as quiet as possible. We do, however, recommend using four separately available insulating feet to reduce the transfer of vibration to the surrounding structure.

When using an Opticlimate and running a low level of extraction or working in a closed loop system, we also recommend supplementing with CO2 to ensure that levels sit within optimal ranges (around 1200ppm). Any CO2 injected into the room will be much more effective, because it has far less chance of being drawn away before plants get to make use of it. You'll be able to maintain perfect PPM levels without having to use as much CO2, saving you money on replacement cylinders. Another advantage of having less air entering the grow area from outside is that unwanted bugs, spores and bacteria will be far less likely to ever get near your plants. It should be noted that different methods of injecting CO2 require different levels of extraction. 'Cold CO2 injection' uses gas cylinders to deliver CO2 to the grow area, whereas 'hot CO2 injection' is done by using systems that burn gasses, such as LPG. Both have advantages and disadvantages, but if you do decide to use 'hot CO2 injection', you will need to use a slightly greater level of extraction to remove some of the gaseous by-products that can potentially be toxic to plants.

The Opticlimate is equipped with a feature that automatically shuts off the water supply if a leakage is detected. A magnetic valve is installed in the water inlet pipe and a leakage sensor is placed under the unit. If water is detected, the magnetic valve immediately shuts off the water supply. The unit can even be set up to send an SMS text message in the unlikely event there is an issue.

It may be that you wish to use the Opticlimate outside of the grow area or tent itself. You can do this easily by fitting some additional parts. A plenum box and flange will enable you to connect 10 inch ducting to the air intake. That way you'll be able to draw air from wherever you position the other end of the ducting (preferably at the top of the room), allowing you to keep the Opticlimate itself wherever you like. Just be aware that long ducting runs can reduce efficiency levels. Keep them as short as possible or look towards increasing the air flow to the Opticlimate's intake by using a separate duct fan.

The treated air that's pushed out through the front of the unit will need to be distributed evenly around the grow area. We recommend using a length (or lengths) of ducting above the canopy. Seal the end of the ducting up and make even rows of holes in the lower area so that the air is forced through any perforations and downwards towards your plants. Please note that the blue flange used to connect ducting to the Opticlimate's air outlet point (as seen on the main image) is not supplied and will need to be purchased separately.

Please note: The Pro 3  is designed to handle up to a recommended amount of lights, but users should take into consideration any additional heat sources before selecting a particular Opticlimate model. If ballasts and other heat-producing items are kept inside the room, they will naturally lower the number of lights that the Opticlimate is able to cool effectively. To get the most from your Opticlimate, mount ballasts and other heat sources in a separate area.

When you choose your Opticlimate, you should consider the size of the room as well as lighting output. The Opticlimate is designed for room areas equivalent to 1.2m x 1.2m x 2.0m for every 600 watts of HID lighting. If the grow space is larger than this, the Opticlimate may have to work harder to maintain perfect temperature and humidity levels.

It is always better to run a larger system than is required and have some spare cooling/ heating power than it is to run an Opticlimate right on the edge of its capacity.

It's advisable to run a separate dehumidifier to take care of excess moisture when the cooling is not in use. We recommend taking a look at the Quest range, which features units that are perfect for the job.

Though installation for this unit is relatively straightforward, we recommend having a quick chat with one of our resident Opticlimate experts before ordering - they've guided dozens of happy customers through the process and they're on-hand to make sure that everything goes as smoothly as possible.

If you just can't wait and want to order straight away, that's fine, but please note that for technical items like these, we generally follow the order up with a quick complementary call to fill you in on a few details and ensure that you are confident about the installation.

Because the Opticlimate requires quite a lot of preparation to ship, it is not subject to the 2.00pm deadline for same day dispatch. However, we guarantee that we will endeavour to get it sent out as quickly as possible. On most occasions this is the next working day.

Using the Opticlimate Pro 3

Installing the Opticlimate is not too difficult and can be done in an afternoon, but it will require a level of proficiency in both electrical wiring and plumbing. Do not attempt to install the Opticlimate unless you are fully competent in these areas. If you are in any doubt whatsoever, please consult a skilled professional. Refer closely to the manual for full instructions. A copy can be found in PDF format in the 'attachments' below this description.

Before setting up the Opticlimate, you will need to consider where you wish to position it, in order to work out whether you will need to purchase any additional parts. The unit can be mounted at the top of the room that you wish to use it in, well away from any lighting systems. It will then draw in hot air, treat the air accordingly, and expel it at the perfect temperature and humidity. However, it should be noted that the air intake is not designed to be fitted with ducting. This will, of course, throw up problems if you wish to use the Opticlimate outside of the grow room, or if you wish to position the unit nearer the floor (something that may be a more convenient for many users). In these cases, you will need to fit a (separately available) plenum box and flange to the air intake.

Remove one of the round sections from the plenum box to create a hole and fit the flange in place around it. You can then attach ducting to the flange. The other end of the ducting should positioned where you wish to draw air from (at the top of your grow room), allowing you to use the Opticlimate without having to mount it directly in the place that you wish to draw air from.

Be mindful of the fact that drawing air into the Opticlimate via a length of ducting can reduce its efficiency, so keep ducting runs as short as possible or look towards increasing the airflow to the unit with a separate duct fan.

Refer to the manual closely when installing the Opticlimate. You will need to:

  • Install a magnetic water valve in the pipework of your cold water supply, install a filter and connect the pipework to the Opticlimate's water inlet. Note that the Opticlimate fittings require 15mm (external diameter) pipework.
  • Connect the Opticlimate's water outlet to a drain with 15mm (external diameter) pipe.
  • Decide how you wish to use water from the dehumidifier outlet (we recommend using it to fill your reservoir tank. The outlet will connect directly to IWS Pro Flexi Pipe (25mm internal diameter). A float-valve activated lifting pump is available separately if you need to move the water to another area.
  • Open up the panel on the front of the unit to get into the electrical compartment and wire a suitable power cable (following the wiring diagrams in the manual) to the terminal strip and create two wiring loops.
  • Wire the magnetic water valve that you installed previously to the Opticlimate.
  • Connect the white plug at the end of the water leakage sensor to the unit (as shown in the manual). Then secure the other end on the ground underneath the Opticlimate.
  • Hang the humistat / light sensor and the temperature probe in the grow area.
  • Connect the controller unit to its tether and use it to program the Opticlimate. The socket on the back of the unit will make it difficult to mount the controller on the wall. For this purpose, we recommend using a suitable patrice box.

How the Dimlux Expert Series 600 Watt Works:

Used by the grow industry, professional 400 Volt HPS lamps have a number of key benefits which make them superior to standard HPS lamps – even ones being run from top-quality digital ballasts.

A 400 Volt HPS lamp is much more efficient than a standard lamp. Both systems consume 600 watts and therefore cost exactly the same to run but the Pro HPS lamps run at a higher voltage and a lower current. Dimlux 400 Volt Pro HPS lamps produce more light for the same power consumption and will deliver at least 10% higher yields compared to even the best standard systems. In fact, when they are seen side-by-side, the HPS Pro lamps are noticeably brighter, run cooler and the light they produce is slightly whiter. So in addition to them giving a higher yield, plants grown under a Dimlux 400 Volt Pro HPS are healthier, happier and are at less risk of heat damage too.

The way that the Dimlux system works is that UK mains power (230 Volts) is fed directly to the combined ballast and reflector via a standard mains power lead. The special ballast then converts the mains electricity to drive the special 400 Volt / 600 Watt Philips Greenpower lamp. The distance from the ballast to the lamp is very short, meaning that virtually no power is lost through the connecting cable and removing the possibility of electromagnetic interference.

400 Volt / 600 Watt HPS Philips Greenpower lamps maintain their efficiency and light output for much longer than standard lamps. In fact they will normally last at least a year before they need to be changed out. It should be noted that normal HPS lamps and 400 Volt Pro HPS lamps are NOT interchangeable with different ballasts. Standard HPS lamps should only be used with standard or digital 230 Volt ballasts. 400 Volt Pro HPS lamps should only be used in lighting systems with a 400 Volt Pro HPS ballast. They can be identified by the HPS EL marking on them.

To get the most from these units, we recommend using them in conjunction with the Dimlux Maxi Controller. You can then do away with your contactor /timer setup and control up to 160 fixtures from a single point, scheduling on and off times and regulating output levels according to room temperature or VPD (vapour pressure deficit). You can also take advantage of numerous features like 'sunrise / sunset' mode, which eases plants between day and night cycles, mimicking the sun.

How to Use the Dimlux Expert Series - 600 Watt:

Hang the combined ballast & reflector over the centre of the grow-space at an appropriate height using easy rolls or jack chain. Run the 4.0m kettle lead from the reflector to a standard UK mains outlet or your contactor and switch on.

Dimlux lighting is best used in conjunction with the Dimlux Maxi Controller. Two of these units can be connected to the Maxi Controller directly using speaker wire, and additional ballasts / fixtures can then be daisy chained from the original ballasts up to a total of 160 units. Multiple units can be powered using the following items:

Green Power Powerbox

Warning 1: When it is time to change out the lamp, make sure that it is replaced with another 400 Volt / 600 Watt Pro HPS lamp such as the Philips Greenpower 400 Volt / 600 Watt HPS EL. Using a standard HPS lamp in a 400 Volt lighting system will possibly cause damage, explosions or fire.

Warning 2: When HID lamps are switched on they run extremely hot. As with all high pressure sodium and metal halide bulbs it is necessary to avoid touching the lamp with anything such as fingers or plants as this may cause severe burns or fires. In particular avoid sprays or liquids coming into contact with the lamp as this may cause premature failure or even an explosion.
