Under Canopy 120W Solux (2pcs) – LED Bars for Lower Buds

The Under Canopy 120W Solux (2pcs) is the ultimate lighting solution designed to penetrate where your main lamp simply cannot reach, transforming those airy lower flowers into rock-hard, high-quality buds. This system consists of two high-efficiency LED bars (120W each) specifically engineered to illuminate the lower and middle sections of your plant canopy, ensuring that every centimeter of your grow space contributes to the final weight of the harvest.

Are you tired of harvesting loose, airy “popcorn buds” from the bottom of your plants?

Without this specific lighting, your indoor grow routine likely involves a frustrating trade-off. You focus all your energy on the main canopy, accepting that the lower branches will produce second-rate flowers. You spend hours pruning and lollipopping, sacrificing plant mass just to avoid those underdeveloped buds, or you end up with a significant portion of your harvest that lacks density and bag appeal compared to the top colas.

This situation is not just annoying; it is a waste of time, electricity, and nutrients. Seeing your plants lush and green on top but weak at the bottom creates a feeling of inefficiency. You know the genetic potential is there, but the lack of photons in the shadows prevents those sites from swelling. It’s painful to trim away potential yield or toss fluffy buds into the “leftovers” pile after months of hard work.

The Under Canopy 120W Solux is the missing piece that organizes your routine and maximizes your efficiency. By introducing light directly into the canopy structure, you ensure uniform photosynthesis throughout the plant. This means you stop sacrificing lower branches and start harvesting premium quality buds from top to bottom, making your entire cycle smoother and significantly more productive.

Before using this lighting system

Before installing these bars, you need to rethink your spatial organization. Unlike a standard top-light setup, you are now working with a 3D lighting environment. You don't need to be as aggressive with your pruning or lollipopping, as the lower sites will now receive sufficient energy to thrive. Ensure your Indoor Grow tent has enough floor space or mounting points on the poles to accommodate the bars horizontally or vertically, depending on your strategy.

• Check your power load: Ensure your timer or controller can handle the extra 240W (120W per bar).
• Plan the placement: Decide if you want them sitting on the pot level facing up or mounted on the side poles facing in.
• Clean the area: Remove dead leaves and debris from the bottom to allow the light to travel freely.
• Adjust your nutrients: With more light comes higher metabolic activity; you might need to slightly increase your feed strength.

During the cultivation cycle

Once the Under Canopy bars are running, the game changes. You will notice that the plants drink more water and demand more nutrients because their photosynthetic rate has skyrocketed. It is crucial to monitor the distance between the LEDs and the leaves; although they run cool, you should maintain about 45 cm to prevent light stress on older leaves. This is the time to watch your lower buds explode in size, something you rarely see with top-lighting alone.

Since these bars are IP65 rated, you don't need to panic if you accidentally splash them while watering. However, keep an eye on the temperature. While LEDs are efficient, adding 240W of power adds heat. Ensure your Ventilation tubes and extractors are adjusted to handle the slight increase in temperature to keep the environment in the perfect VPD range.

After: results and maintenance

When harvest day arrives, the difference will be undeniable. Instead of separating “A-grade” tops from “B-grade” bottoms, you will find a much more homogeneous crop. The trimming process becomes faster because you aren't fighting with leafy, structureless buds. You will likely see a significant increase in Grams per Watt (GPW), making the investment worth it in just one or two cycles.

Maintenance is minimal but necessary. Once the cycle is over, simply wipe the bars down with a damp cloth to remove dust or resin splashes. Thanks to the IP65 protection and lack of moving parts (passive cooling), these units are built to last over 50,000 hours, ready for your next run immediately.

Short- and long-term advantages and benefits

• Elimination of Popcorn Buds: Transforms fluffy lower flowers into dense, sellable product immediately.
• Higher Total Yield: Increases the overall weight of your harvest by activating dormant bud sites.
• Full Spectrum Efficiency: The optimized spectrum targets growth and resin production specifically for mature plants.
• Water Resistance (IP65): Allows you to work comfortably with irrigation systems without fear of damaging the equipment.
• Scalability: You can daisy-chain multiple units (up to 7 at 120V), making it perfect for expanding operations.
• Energy Optimization: You get more product for the electricity used, improving your ROI over time.
• Versatility: Fits in tight spaces where traditional Full spectrum led grow lights cannot reach.

Frequently Asked Questions

How close can I place the bars to the plants?

It is recommended to keep a distance of approximately 45 cm from the canopy to ensure optimal spread and avoid light saturation, although this can vary depending on the plant's stage.

Can I use these bars for the vegetative stage?

Yes, but they are incredibly powerful. For small plants, they might be overkill. They shine best during the flowering stretch and bloom phase to harden up the buds.

Do I need a separate timer for these?

Ideally, yes, or connect them to your main controller. You want them to turn on and off in sync with your main lights to maintain the photoperiod.

Are they compatible with other brands of main lights?

Absolutely. The Under Canopy 120W Solux works as a supplement to any main lighting system, whether it's HPS, CMH, or another LED brand.

Personal Experience of Pevgrow’s CEO (Alan)

I used to be skeptical about adding more watts to the bottom of the tent. I thought, “Is it really worth the electricity?” But after testing the Solux Under Canopy bars, my routine changed. Before, I would spend hours lollipopping, stripping the bottom third of the plant entirely. Now, I leave more branches because I know they will actually produce.

During the grow, I place them angled slightly upwards from the corners. The way the lower buds frost up is incredible—sometimes they look even frostier than the tops because they are closer to the light source! Afterward, the trimming is a breeze. I don't have a “trash pile” of airy buds anymore. If you want to hit that 2 grams per watt mark, this is the secret weapon you’ve been missing.
