Why Do You Need the Glow30 Side Lighting?

Most grow lights are mounted on top of grow tents, but light struggles to penetrate deep into the lower canopy. This means lower buds and branches receive less light, resulting in slower growth, smaller yields, and lower potency compared to the top. Without proper lighting,you’re not maximizing your plant’s full potential.

Spider Farmer Glow30 solves this problem(Side lighting, under lighting, supplemental lighting)! It provides targeted side lighting, ensuring that lower buds receive the extra light they need to grow bigger, denser, and healthier. The flexible installation lets you mount it on grow tent sidewalls or place it anywhere for optimized light distribution.

Plus, it’s super energy-efficient—just 32W! Even if you run it 4 hours per day for 21 days, your electricity cost will only be a few dollars. With better light coverage and bigger yields,Glow30 is the upgrade your grow setup needs.

Length of wires at both ends of a single light bar:
70cm/25.56”

Fast Shipping

Same day delivery, 3-8 business days for the product to reach you.

What could cause my Glow30 to become detached from the grow tent, and how can I securely reinstall it?

1. Velcro was not mounted vertically :
Always attach Velcro strips vertically for maximum grip. The light can be rotated, but the Velcro direction should stay upright.
2. Insufficient Velcro coverage :
Use the extra-long Velcro strips provided. Cover as much area as possible, especially ensuring it extends beyond and fully covers the fixing clips.
3. Unclean grow tent wall surface:
Dust, oil, or moisture can weaken adhesion. Clean the tent wall with alcohol or water before applying the Velcro.
4. Velcro not pressed firmly:
After positioning, press the Velcro down along its full length to secure it properly.
5. Misalignment :
Ensure the Velcro is straight, with no twisting or gaps.

    I am very happy with the overall build quality of the lights, they feel sturdy and should be able to handle grow room conditions. At 32w they aren’t the most power hungry lights but they pack a lot of light into the under canopy, generally top lights will penetrate about 2 feet into the canopy, so these will help add light to any lower budsites that might need it. I’m going to be using these as undercanopy lights in my 2×2 along with my Spider Farmer G3000. These lights are a great value and high quality product that should be perfect for anyone that needs supplemental light in their garden!

    I purchased some shelves for plants in my bedroom and these are THE BEST bar grow lights i have found. These also come with easy install pieces making it easy to attach to a wall. I had these in my shower for some time and it brightened up the space very well.

    I’m a home gardener,they work perfectly for what I need them for, growing plants under artificial lighting conditions, in an enclosed space. I have multiple glass curio cabinets that I keep my rare plant collection in, and my first cabinet was much smaller than I anticipated, so my 2 foot grow lights wouldn’t conveniently fit. I was looking for something roughly 18 inches, and these guys were close enough.

    They fit comfortably in my 22 inch interior width cabinet, and provide enough light for the plants on each of the 4 shelves. I also appreciate how they have the ability to be set up in a frame for one large area like a grow tent, if that’s more your thing. Overall, I’d say my plants are happy, so I’m happy. I’d definitely purchase again if they were on sale again, since the regular price point is a bit too steep for me. (But honestly with how much I’ve spent on plants, it’s worth it to have superior light for them🤷🏼‍♀️) I’m definitely interested to try more from spider farmer in the future!

Why Choose Our Supply Series Supplemental Light Bars?

In some main light sources, a few 365 UV diodes and 730nm IR diodes may just be a marketing gimmick, and in reality, their intensity may be insufficient. Among all the supplemental light bars in our lineup, the supplementary light bars in the Supply series feature the most densely arranged diodes, specifically designed to enhance plant growth. Our 23.6-inch(60cm) UV & IR light bar set consists of 4 bars, each UV light bar equipped with a durable and sturdy metal casing and 60 diodes, while each IR light bar equipped with a durable and sturdy metal casing and 44 diodes.

Why use 730nm IR supplemental light bar? Stem Boost, Flower Induction, Light-induced Sleep

Why use 365nm UV supplemental light bar? Enhance yield, improve nutrients, elevate taste/aroma, sterilize grow area (eliminating mold), aid pest control.
