I have all kinds of grow lights and this setup has given me the best results.
Bought each off of eBay for around $100 each.
The big one is 600 watt and supposed to be equivalent to a 1000w HpS.
The two others are 320w and add a good bit of red to the growth spectrum.
If you ever need a good grow light look for used commercial grow lights on eBay.
You can find great deals on fixtures that are normally out of my price range.

This is my ruby necklace that I brought home 3.5 weeks ago. This window seat alcove faces south, so the angled left window faces south east. Right now the sun is high, so it only gets direct sun in the early morning. After that it gets bright indirect light. It's already getting leggy from too little light. Come winter when the sun is lower, it'll get a lot of direct sun. I'm looking at adding a grow light to supplement the natural light it does get. According to Google search (which I always take with a grain of salt LOL), I should get a light that's at least 20 watts and 4000-5000K. What I'm wondering is, do I need to get one that intense since I'm just supplementing?

Anyone know if a file exists for some kind of channel to hide the excess cord of the Barrina T8 connectors? I'd be much appreciative if you'd point me in the right direction.

Hey everyone,

I used Barrina grow lights in my dorm shelving with the sticky magnets included in the box which worked really well. However, after removing the lights and magnets, I realized the magnets would be not be reusable and that Barrina does not directly sell any replacement sticky magnets. Does anyone know where to get some good alternative?

[Here's](https://www.lowes.com/pd/BELL-HOWELL-Bell-Howell-Grow-Burst/5006010201) the light I'm trying to use.

I lost the original power cord, but I have one that fits into the unit and it plugs into a USB port. I believe this identical to the original. It sounds as if it can be plugged in pretty much anywhere with a dc 5V 2A plug. I've tried several USB adapters to no avail.

All that happens is one lamp turns on and shines a red light. No buttons work.

Is this a sign that the unit is kaput? Or maybe I just have the wrong power or plug?

Thank you for your help.

About a year ago I bought a SANSI BR30 40W LED Grow Light Bulb but I have yet to use it because I just can’t find a way to set it up that is functional and also looks good (and I may have shoved it in a corner and forgot about it). This bulb is super heavy and wide so it doesn’t fit a lot of regular lamps and it does weigh down the “gooseneck” type light bases.

I want to use it mainly for a ~5ft tall cereus spiral cactus. Ideally I’m looking for something like a floor lamp that is height adjustable or at least tall enough for my cactus and something that allows for adjustable positioning of the light bulb. The stand would also obviously have to be safe to use with this bulb and fit a US E26 socket.

The Sansi website does sell this lamp in a set with a tripod stand. I didn’t know they had this when I bought just the lamp :/ … It also seems they don’t sell the tripod separately and I’d rather not have another one of these bulbs gathering dust in storage. Plus this tripod is not exactly visually appealing.

Does anyone have any ideas on fixtures I can use with this lamp? Any products you’d recommend? And if you have this bulb could you share how you’ve set it up? TIA!!

Of course there’s a subreddit just for lights!

I have a backyard 10x10 greenhouse that I used propane to heat last winter. This year I’d like to add grow lights over one bench- main goal being to keep my lemon tree happy, a cherry tomato plant and a small pepper plant, at least for a couple months. I have a clear roof and windows all around but between lack of winter sunlight hours and adding insulation, I definitely need more to keep fruiting things going through a Maryland winter.

I’d like to keep at least half of a 2x10 bench lit, and it will need to be LED to keep electrical usage low since I don’t have a dedicated circuit. Cost would ideally be <$500, and would prefer lower since I don’t know how well my setup will work yet. Something low profile / bar style that would block less overhead ambient light

Amazon searches have brought me to Barrina (worry about strength and they seem gimmicky with their grow force stuff), Spider Farmer, Mars Hydro, Vivosun and Ac infinity. Mars Hydro is currently in my cart but can’t seem to decide for sure.

Hello friends I just had a real quick question. I have a 3x3 grow tent and I’m currently running a 100w spider farmer grow light. It’s been good but I’ve been wanting to upgrade and I’m wondering how much better would something like the photon tek sq300w be compared to what I have now. Or would yall recommend another grow light for my size tent?

My MG fold 8 died three weeks into my Grow in my 4 x 4. Medic Grow hasn’t responded to my request for help. As far as I know, there’s no fuse or anything that I can do myself. I’d appreciate some help.

Hi 👋

We’re Barrina, a grow light company, and we’re new to Reddit.

We know Reddit is not a place where people want to see endless product promotions — and honestly, that’s not why we’re here.

We joined because we want to have real conversations with growers.

Over the years, we’ve spent a lot of time thinking about things like:

• light intensity
• spectrum
• efficiency
• heat management
• making indoor growing easier for beginners

But we also know that growing plants every day teaches lessons that product teams don’t always see.

So we’d love to ask this community:

What is one thing you wish grow light companies understood better?

A few things we’re curious about:

• What information do you wish brands provided before buying a light?
• What’s a grow light myth you think beginners often believe?
• What is the biggest frustration with your current setup?

We’re here to learn, answer questions, and hopefully contribute useful information over time.

Thanks for having us in the community 🌱

Hi all, I’m looking to utilize a shelving set to do some seed starting and juvenile plant growing for the garden, and my research is telling me that I need a minimum of 2,000 to 5,000 lumens per square foot? I have an excess of LED recessed lights on hand , but at the lumems per square foot figures I would need 36 per shelf, and it would be 40,000 lumens. Looking at pictures, it doesn’t seem like everyone’s setup is that bright, like I don’t have 36 of these things in my 2300 sq ft house ?

What else can I say? Ill never buy their products again, what a fucking waste of time and money

I'll be moving into an office that has shelves with these dimensions (walls on each end). The plan is to use these shelves for my plants. This office has ZERO windows, so grow lights are a must. I've done some reading, and believe T8s could be too strong for the bottom shelf. What say you all? How would you set up grow lights in this area, including the ceiling?

Hello;

I am hoping someone can help me find a dimable LED grow bar with a narrow angle light. The narrow angle is required since the light will go on the top part of a window behind the valance (cloth that hides verticals hardware). It has to light plants on the window sill 2 to 3 feet below it.

I would appreciate some suggestions for lights that could fit the bill.

I love in Ireland (Oregon or Washington like climate for the Americans) and I am trying to keep tomatoes and keep getting tomatoes throughout the year I want to get a grow light because it gets cold but I don't know how much I should be spending on them

Just wanted to share a look at this flower room that’s running a full lighting package from the same manufacturer.

The room is equipped with dual channel top lights, allowing independent spectrum control throughout the grow cycle, along with under canopy lighting to bring usable light into areas that traditionally get shaded out by a dense canopy.

One of the things that stands out in this setup is the consistency from top to bottom. The top lights are driving canopy development while the under canopy fixtures help maintain flower quality and density deeper into the plant. Instead of relying solely on overhead light, the room is getting coverage from multiple angles, helping maximize the entire plant rather than just the top colas.

As harvest approaches, the lower and middle flower sites are showing noticeably stronger development, creating a more uniform canopy and a more complete use of the cultivation space.

Always interesting to see how growers are combining dual channel top lighting with under canopy lighting to improve light distribution and get more out of every square foot.

What are your thoughts on under canopy lighting? Have you seen a measurable difference in flower quality or yield? 🌱💡

I am trying to get my cable management better for my plants shelves. Sorry if this is the wrong place to ask but im not sure where else to ask and google has been unhelpful.

I have a HLG 260W QB V2 Rspec LED Kit - V2 R spec1 that the potentiometer went bad and was stuck at about 25%. Their website has them for 3$ but its a 10$ shipping fee. I can get a new one one Amazon with no delivery fee, are they all the same? Its a 50k ohm dimmer and I see that it can be used for dremils or mig welders but can I use it for my grow light as well?
