Better Light Spectrums = Better Plant Growth

Research engineered light recipes for your plant type & growth stage
Sun White Spectrum

This all-natural light spectrum boosts healthy growth rates for house plants, microgreens, flowers, fruits and more. By mimicking sunlight conditions with a high CRI of 95, the Sun White Spectrum will make your garden look more vivid and it will be easier to detect pests and deficiencies before they spread. This truly full-spectrum light extends beyond the traditional PAR range (400-700 nm) to include far-red wavelengths that increase photosynthesis rates via the Emerson Effect.

Easy Lamp Installation

Insert each lamp with the end cap marked L N into the lamp holders located on the same side as the fixture's switches and power cable. Once the lamp is inserted, rotate a quarter turn until the lamp is locked in place.

Sturdy Hanging Hooks

Removable metal hanging hooks allow for a quick installation using standard hydroponic hangers, zip ties, S-hooks and more (hanging equipment sold separately).

Dual On-Off Switches

Water-resistant dual on-off switches allow growers to run all 4 lamps, 2 inner lamps or 2 outer lamps to meet target lighting requirements for different plant types and growth stages.

Daisy Chain Cable Installation

Easily connect multiple fixtures by plugging the 6' power cord into the socket side of the next fixture for a versatile and clean installation.

Active Grow lights have been a great all around light. They produce beautiful reds in your lettuce, strawberries and beets. Don't waste your time on long drawn out searches for grow lights on YouTube these 'absolutely' will work for you.

Knowledgeable customer focused horticultural products dealers

I have purchased grow lights directly from Active Grow and have found this organization to be an excellent source for product recommendations with a concern for customer satisfaction from order to final delivery.

Excellent LED grow lights and outstanding service

The grow lights are all they are advertised to be. Installation was easy and we starting seeing sprouting very quickly. A much better result than we ever had before.
We were initially confused as to how many LEDs we had received and emailed a query about this; I was expecting a computer based response. Instead, we got a phone call back within 15 minutes and a friendly and knowledgable person carefully explained what we had gotten wrong. This was the best service experience I have ever had.
Highly recommended company

LOVE Active Grow!

I LOVE my Active Grow T5 2.O HO 4Ft 4 lamp fixtures Sun WhiteSpectrum. They are so easy to setup, high quality, yet light weight and sleek! My seedlings 🌱 are growing beautifully, no stretching and impressive root development. I highly recommend this product and this company. GREAT customer service!

Good for starting vegetables. We're eating lettuce that we grew indoors with this light. Our other veggies are off to a good start. We have three daisy-chained together set on one timer. The ability to turn on all or half of the lights gives a little extra control.

After buying Amazon grow lights that did absolutely nothing past the germination stage, I found this company. The light I got far exceeded my expectations. My Amazon led grow lights (that were not cheap) promised huge harvests but only delivered leggy veggie sprouts with absolutely no root development. Two weeks under this light and look what I got now! Spending money on stuff that doesn't work is really frustrating. I will be buying more from active grow for sure. This light is amazing!
