FAQs

Can I use this for all stages of plant growth?+

Yes, the Sun White spectrum and dual switches make it ideal for both vegetative and flowering stages, providing the necessary wavelengths for every phase of development.

How many units can I daisy chain together?+

You can connect up to 4 units on a standard 120V circuit or up to 8 units on 208V-277V circuits, allowing for easy expansion in larger grow rooms.

Does this light require a separate ballast?+

No, this fixture features a ballast-free design. It uses ballast-bypass LED lamps, which eliminates the common failures, buzzing, and flickering associated with traditional T5 ballasts.

What is the recommended hanging height?+

We recommend a hanging height of 12-24 inches above the plant canopy. For high-light plants like cannabis, 12 inches is optimal, while 24 inches is suitable for leafy greens or seedlings.

Is the Sun White spectrum better than standard LEDs?+

The Sun White spectrum is superior because it features a high 95 CRI and includes far-red wavelengths. This triggers the Emerson Effect for faster growth and makes it much easier to see the true health of your plants.

Build w/ a Friend, and BYOL (Bring Your Own Level)
Size: 4-tier, Style: wall mount&floor mount
Definitely a two-person job. Not because it's heavy, but a little awkward at first. I installed the first bracket, and my 12 yo assisted. Then, she hung the second bracket, and I assisted. Have a level handy. I didn't want to roll the dice and allow her to hang from the bracket, but it seems super-strong. We hung the brackets 32" apart, and 6" overhang, i.e. 48" x 12" laminate shelves. Gorgeous.

Nice, sturdy kit...would buy again!
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
Purchasing this kit instead of each piece of pipe and fittings required was a no-brainer. It was especially easy because all pieces are prepainted. It went together with ease. Mounting was simple with planning, measurements, and a level. *Note* I purchase the pine stair treads from Home Depot that are 1" thick and then chemically aged them before adding polycrylic. It is cheaper than plywood and shelving boards, and a full 1" thick rather than 1x12 shelving.

Looks amazing!
Size: 4-tier, Style: wall mount&floor mount, Size: 4-tier, Style: wall mount&floor mount
Very straight forward to build. Mine was not hard but to a bit more effort because my ceiling is at an angle so I had to get a little creative. I cut a piece of wood and placed it between the ceiling and one of the arms for it to be even. It’s also not completely even cause I didn’t have a long level but still looks amazing.

A Spa-tacular Addition to My Bathroom Oasis!
Size: 24in-Shelve
Perfect Statement Piece for My Spa-Like Bathroom! I know this review is super delayed~I’ve been living out of the country, and only just got around to installing this beautiful shelving unit. But wow, it was worth the wait! I hung it in my bathroom above the jacuzzi tub where I have vaulted ceilings and a skylight, and it fits perfectly. It adds the perfect industrial-chic touch I was looking for. I use it to store all my bath oils, salts, and candles, and it’s transformed the space into a relaxing, elevated sanctuary. The quality is fantastic and it was easy to install. Honestly, it looks like something out of a spa catalog. Highly recommend for anyone looking to upgrade their bathroom with both function and style!

Great deal for the money, look sharp, and very sturdy
Size: 32in-Shelves, Size: 32in-Shelves
I was looking to create pipe shelves in our living room. After spending some time researching prices for pipe and wood, I determined that I would save money by buying a couple sets of these shelves. When the shelves came in, I was happy to learn that they were indeed good quality and easy to assemble. They come with mounting hardware, but I’d recommend better mounts for the walls than the ones supplied. Overall, I love the look of these shelves. The wood is described as reclaimed, but it’s pretty much cheap, light wood with a stain. They still look good and are sturdy. The pipes has some silver paint brushed on them to give them a distressed look. I thought it was actually a little cheesy looking, but I happened to have iron-colored spray paint, so I just respirated them.
