Best Side Lighting for Grow Tent: Boost Your Yields

1. Barrina T5 Grow Lights

We’ve been experimenting with Barrina’s 1ft T5 lights for supplemental side lighting in a modest grow tent, and they offer a surprisingly effective, budget-friendly solution. The slim profile makes them easy to position just about anywhere, and the simple plug-and-play setup means you’re up and running in minutes. I found the light output to be adequate for filling in shadows on lower canopy branches, especially for seedlings and vegetative growth stages.

The construction feels reasonably sturdy for the price point, though the plastic housing doesn’t inspire the kind of confidence you’d get from a more premium fixture. The included mounting clips are functional but can be a bit fiddly to get just right, requiring some patience. If you’re looking for a no-frills way to boost light penetration in smaller spaces, these are definitely worth considering.

This is ideal for growers working with limited space or those on a tighter budget who need to supplement their main light source. Skip these if you expect a high-end build quality or need intense light for flowering heavy, light-hungry plants.

2. Spider Farmer Glow30 LED Grow Lights

The Spider Farmer Glow30 presents a compelling option for those seeking a compact, full-spectrum LED for supplemental lighting. We appreciated the sunlike spectrum, which mimics natural sunlight and appears to promote healthy, even growth. The unit itself feels well-built, with a solid metal housing that dissipates heat effectively, meaning no annoying fan noise to contend with.

During our testing, the light distribution was fairly uniform, and it did a decent job of reaching the lower parts of our plants. However, the included dimmer knob, while a nice feature, has a slightly loose feel to it, making precise adjustments a bit less satisfying than I’d prefer. For a small tent or as a dedicated light for a few plants, this is a strong contender.

This light is a great fit for growers who want a quiet, efficient, and spectrum-accurate light for a small grow space or for supplementing a larger fixture. If you require a very wide coverage area from a single unit or are on a shoestring budget, you might want to look elsewhere.

3. Barrina T5 Grow Lights

Barrina’s 5000K T5 full-spectrum lights are another budget-friendly choice that we’ve integrated into our grow tent setup, specifically for achieving the best side lighting for grow tent applications. Their cooler 5000K temperature is excellent for vegetative stages, promoting bushy growth without stretching. The ease of daisy-chaining multiple units is a significant advantage, allowing for flexible coverage across larger tents.

I found the light intensity to be sufficient for filling those often-neglected lower canopy areas, preventing light deprivation. The aluminum casing feels adequate, though not premium, and the power cords could be a touch longer for more versatile placement options. Overall, these offer great value for growers looking to improve light penetration without breaking the bank.

This is an excellent choice for anyone looking to optimize their grow tent with supplemental side lighting, especially during the vegetative phase. Avoid these if you need a high-intensity light for flowering or demand a robust, heavy-duty construction.

4. Ac Infinity Ionbeam S16 LED Grow Light Bars

The AC Infinity IONBEAM S16 offers a sleek and powerful solution for growers serious about optimizing their light coverage. We were impressed with the build quality; the aluminum bar feels robust and well-finished, and the integrated heatsink design ensures silent operation. The full-spectrum output is well-balanced, and I noticed a distinct improvement in the density of growth on lower branches when using these as side lights.

The modular design is a definite plus, allowing for easy expansion if needed, and the included mounting hardware is thoughtfully designed for secure attachment. My only minor quibble is with the placement of the power input; it feels a little exposed, and I would have preferred a more recessed connection. Despite this small point, these bars deliver impressive performance for their size.

These IONBEAM bars are perfect for growers who want a premium, quiet, and highly effective supplemental lighting solution for larger tents or for those who want to precisely control light distribution. Skip this if you are on a very tight budget or only need basic light for a small seedling setup.

5. Vivosun Lumaray LED Grow Light Bars 16″(4

VIVOSUN’s Lumaray LED bars provide a solid, no-nonsense option for enhancing light penetration in your grow tent. We found the 16-inch length to be convenient for fitting into various tent configurations, and the full-spectrum output appears to support healthy plant development. The setup process was straightforward, and the light bars themselves feel reasonably well-constructed for their price point.

The light diffusion is decent, helping to spread the illumination across the lower canopy. I did notice that the power cord, while functional, feels a bit thin, and I would have preferred something with a slightly more substantial gauge for peace of mind. Nonetheless, these bars offer a practical way to address light deficiencies in shadowed areas of your plants.

These VIVOSUN bars are a good choice for growers looking for an affordable and easy-to-install supplemental light for their grow tents. If you are seeking advanced features, extremely high light intensity, or premium build materials, you might find these a bit basic.

6. Vivosun Lumaray LED Grow Light Bars 16″(8

We put the VIVOSUN Lumaray LED Grow Light Bars to the test, specifically focusing on their application as side lighting in a grow tent. The 16-inch length with 8-inch spacing between the LED strips is a thoughtful design for covering a decent area. I found the light output to be quite uniform across the intended coverage zone, which is crucial for preventing light deprivation on lower branches.

The build quality feels solid, with a sturdy aluminum housing that dissipates heat effectively. We noticed a slight warmth during prolonged use, but it never became concerning. The included mounting hardware was straightforward to use, allowing for quick installation either horizontally or vertically along the tent poles.

One minor annoyance we encountered was the slightly stiff power cable connection; it required a bit more force than anticipated to secure it properly. This is a small point, but for frequent setup and takedown, it could become a minor hassle. It’s important to note that these bars are best suited for tents with a moderate footprint where precise, focused side lighting is needed.

This setup is ideal for growers looking to supplement their main canopy light and ensure even development throughout the plant’s structure. If you’re aiming for dense buds all the way down, these bars can certainly help achieve that goal. However, if you’re working with a very large grow space, you might need multiple units or consider a different form factor.

7. Vivosun Lumaray Under Canopy Grow Light

When considering the best side lighting for grow tent applications, the VIVOSUN LumaRay Under Canopy Grow Light presents an interesting option. Its full-spectrum, dimmable LED output is a significant advantage, allowing for fine-tuning light intensity to suit different growth stages. We appreciated the ability to dial back the brightness during seedling phases and ramp it up as flowering approached.

The slim profile of this light makes it incredibly versatile for tucking into tight spaces within a tent, especially under the main canopy or along the sides. I found the dimming knob to be responsive, offering a good range of adjustment without noticeable jumps in intensity. The build feels reasonably robust, though the plastic housing for the dimmer knob feels a little less premium than the rest of the unit.

A minor point of contention for us was the length of the power cord; it felt a tad short for some tent configurations, requiring an extension if your power source isn’t immediately adjacent. This light is not for those who need a very broad, overhead-style illumination; its strength lies in its targeted, supplemental coverage.

This light is particularly beneficial for growers who experience light shadowing on their lower buds or want to encourage more even development across the entire plant structure. Its dimmability makes it a forgiving choice for beginners who might be unsure about optimal light levels. Those seeking a primary light source for a large canopy should look elsewhere.

8. Vivosun T5 Grow Lights

The VIVOSUN T5 Grow Lights, with their 5000K full-spectrum output, offer a clean and effective light for plant growth. We tested these primarily for supplemental side lighting in a grow tent, and their consistent illumination was quite impressive. The color temperature provides a natural look, making it easier to assess plant health by eye.

The unit feels well-constructed, with a sturdy casing that houses the T5 bulbs securely. During operation, we noticed a very faint, high-pitched hum from the ballast, which while not overly intrusive, might be noticeable in a very quiet environment. Installation was straightforward, and the included hanging brackets are functional.

One aspect that could be improved is the reflectivity of the internal housing; we felt a slightly more polished surface could have enhanced light distribution further. This light is an excellent choice for those needing reliable, broad-spectrum illumination for smaller spaces or as a secondary light source. However, if you require an intensely focused beam for specific plant zones, this might not be the most efficient option.

We found these lights to be particularly good for vegetative growth and for providing essential light to plants that might otherwise be overshadowed. They are a solid, no-frills option for maintaining healthy plant development. Skip these if you’re looking for advanced features like spectrum tuning or extremely high light intensity for flowering.

9. Spider Farmer T5 LED Grow Lights

We evaluated the Spider Farmer T5 LED Grow Lights, specifically the 1-foot full-spectrum model, for their efficacy as side lighting in grow tents. The light output is bright and evenly distributed, providing substantial coverage for its size. I appreciated the clean, crisp light quality, which made plant inspection quite straightforward.

The build quality of these units is commendable; they feel solid and well-assembled with a durable metal casing. During our testing, we noted that the power switch, while functional, has a slightly mushy tactile feel, which is a minor ergonomic quibble. The included mounting hardware is adequate for most tent setups.

A small annoyance we encountered was the somewhat limited adjustability of the included hanging wires; they could have been longer to offer more flexibility in height placement. These lights are highly recommended for growers seeking reliable, high-quality supplemental lighting for smaller grow spaces or specific plant areas. Avoid these if you’re expecting a very wide spread of light from a single unit.

These 1-foot bars are perfect for adding targeted light to the lower sections of plants or for illuminating shelves in a multi-tiered grow system. They offer a good balance of intensity and spectrum for promoting healthy growth. If your primary goal is to light a large, single canopy from the side, you’ll likely need multiple units.

10. Farmlite Grow Light Bars

The FARMLITE Grow Light Bars are designed with under-canopy and side lighting in mind, and we found them to be quite effective in these roles. The full-spectrum output provides a well-rounded light that plants seem to respond positively to. We observed good penetration into the lower canopy, which is essential for maximizing yield.

The construction of these bars feels robust, with a decent weight that suggests quality components. While operating, we noticed a very low, almost imperceptible hum from the driver, which is a positive for maintaining a quiet growing environment. The mounting options provided were sufficient for our testing purposes.

A minor point of critique is that the end caps on the bars feel a little less substantial than the main body; they could perhaps be more securely attached. These bars are an excellent choice for growers who want to ensure that their entire plant structure receives adequate light, especially those with dense foliage. They are not the best fit if you’re looking for a primary overhead light source for a very large tent.

For those seeking to eliminate light pockets and promote even bud development from top to bottom, these FARMLITE bars are a worthy consideration. They fill a crucial gap in supplemental lighting. If you’re a beginner who wants to improve overall plant health without complex controls, these are a good starting point.
