Adjust-a-Wings Cooltube Conversion Kit – Maximize Reflection & Lower Heat

The Adjust-a-Wings Cooltube Conversion Kit is the essential hardware bridge designed to fuse the two most popular lighting technologies in the cannabis world: the superior light spread of the Adjust-a-Wings reflector and the thermal control of the Cooltube. This accessory allows you to mechanically join both components, creating a hybrid lighting system that maximizes light intensity on your canopy while actively extracting the heat generated by the bulb.

Why you need to upgrade your lighting setup

Problem: You love your Adjust-a-Wings because it covers every corner of your grow tent, but when summer hits or your plants stretch too much, heat becomes a nightmare. High-pressure sodium (HPS) bulbs emit massive amounts of infrared heat, forcing you to raise the lamp to avoid burning the tips. This creates a dilemma: either you burn the plants, or you move the light away and lose precious lumens, resulting in fluffy, airy buds.

Agitation: There is nothing more frustrating than watching your crop suffer from heat stress—curled leaves, stalled growth, and evaporated terpenes—simply because you can't control the bulb's temperature. You are wasting electricity on light that isn't reaching your plants effectively because distance follows the inverse square law: double the distance, quarter the intensity. Your harvest potential is literally evaporating into hot air.

Solution: This conversion kit solves the equation perfectly. By mounting a Cooltube inside your Adjust-a-Wings, you can connect it to your Air Extraction System to suck the heat directly out of the bulb before it enters the room. This allows you to lower the reflector significantly closer to the plants without burning them, drastically increasing the PAR light they receive and improving density and resin production.

Before installing the kit

Before you start hacking your setup, you need to ensure you have the right components. This kit is the connector, so you need the "wings" and the "tube." It is crucial to choose the correct diameter for your ducting and bulb wattage.

• Check the diameter: Ensure you select the kit matching your Cooltube size (125mm for 400W/600W or 150mm for 600W/1000W).
• Prepare the tools: You usually only need a screwdriver and perhaps a small wrench; the assembly is intuitive.
• Plan the airflow: You will need flexible aluminum ducting to connect the Cooltube to your extractor.
• Clean everything: Before assembly, clean the Cooltube glass and the reflector aluminum to ensure maximum Reflective material for grow room efficiency.

During use: The hybrid advantage

Once installed, the difference in your grow room's Climate Control is immediate. You will notice that the thermometer reading at the canopy level drops significantly, often by 3°C to 5°C, even if the ambient room temperature remains the same. This is because the radiant heat from the bulb is being trapped behind glass and whisked away.

This drop in temperature allows you to be aggressive with light placement. You can lower the Adjust-a-Wings much closer to the colas than you ever dared before. The "Super Spreader" might still be useful, but the Cooltube does the heavy lifting. Watch your plants closely; they will drink more water and nutrients because their metabolism speeds up with the increased light intensity.

After: Results and maintenance

After a full cycle with this hybrid setup, the results speak for themselves: harder, denser flowers and a more resinous product due to lower heat stress preserving the terpenes. You effectively get the yield of a large reflector with the safety of a cooled system.

Maintenance is simple but vital. The glass of the Cooltube will accumulate dust and mineral deposits over time, which blocks light. Wipe the glass inside and out with a soft cloth and glass cleaner between cycles. Also, check that the flanges holding the tube to the wings remain tight, as vibrations from the extractor fan can loosen screws over months of operation.

Advantages and Benefits (FAB)

• Temperature Reduction (Benefit): Allows you to grow in warmer months or confined spaces without overheating your crop.
• Increased Yield (Advantage): By bringing the light closer without burning, you increase the lumens reaching the buds, leading to heavier harvests.
• Versatility (Feature): Available for 125mm and 150mm tubes, and compatible with existing Adjust-a-Wings Enforcer or Avenger models.
• Cost-Effective (Benefit): You don't need to buy a whole new expensive air-cooled reflector; you just upgrade the one you already have.
• Safety (Advantage): Reduces the risk of accidental burns if plants stretch unexpectedly during the flowering stretch.

Frequently Asked Questions

Does this kit include the reflector and the tube?

It depends on the option you choose. You can buy just the conversion pieces (brackets/hardware) if you already own the reflector and tube. Alternatively, we offer full packs that include the conversion parts plus the Cooltube (125mm or 150mm). The Adjust-a-Wings reflector wings are usually sold separately or used from your existing setup.

How much closer can I put the light?

With a Cooltube installed and proper ventilation, you can often reduce the distance by 30-50% compared to an open bulb. For a 600W HPS, you might go from 60cm down to 30-40cm, but always test with the back of your hand at canopy level first.

Does the glass block UV light?

Standard glass does filter a small amount of UV, but the gain in light intensity from moving the lamp closer far outweighs the minor loss in spectrum filtration.

Personal Experience of Pevgrow’s CEO (Alan)

I remember the first time I tried to rig a Cooltube onto my Adjust-a-Wings years ago using wire and duct tape—it was a disaster waiting to happen. When these official conversion kits came out, it was a no-brainer. In my experience, this is the single best upgrade for HPS growers struggling with heat.

I use the 150mm version with a 600W bulb. My routine is simple: I keep the glass impeccably clean. Every week, I wipe the outside of the tube because dust settles fast. The difference in bud density on the lower branches is massive because the light penetration is so much better when you can drop that lamp 20 centimeters lower. If you are fighting high temps in July or August, don't swap your lights; just add this kit.
