Active Grow T5 HO 2.0 4FT 4 Lamp LED Grow Light - Red Bloom Pro Spectrum

Struggling to achieve the flower density and fruit yields your plants are capable of? Standard lighting often lacks the specific red wavelengths required to trigger robust reproductive growth. The Active Grow T5 HO 2.0 4FT 4 Lamp LED Grow Light with Red Bloom Pro Spectrum is the professional solution, engineered specifically for flowering and fruiting stages to promote maximum bloom development and enhanced harvest quality.

This high-performance 100-watt LED system is a direct, energy-efficient replacement for traditional 216W fluorescent fixtures, slashing energy consumption by 54% while providing superior light quality. Unlike conventional T5 setups, this fixture features a ballast-free design, eliminating the common issues of buzzing, flickering, and expensive ballast failures. Growers looking for full-cycle performance might also consider the Active Grow T5 HO 2.0 Sun White Spectrum for the vegetative phase, or the 8-lamp version for larger canopy coverage.

The specialized Red Bloom Pro Spectrum is formulated with targeted red wavelengths that stimulate phytochrome responses, essential for transitioning plants into their reproductive phases. This results in stronger budding sites, increased essential oil production, and denser flowers. Built with a lightweight 5.6-pound polycarbonate body and dual on-off switches, this system allows for precise lighting management in any commercial or home grow environment. For smaller supplemental needs, the Active Grow Red Bloom 2FT strips offer similar specialized spectrum technology in a more compact form factor.

FAQs

What is the Red Bloom Pro Spectrum best for?+

The Red Bloom Pro Spectrum is specifically designed for the flowering and fruiting stages of plant growth. Its enhanced red wavelengths stimulate phytochrome responses that promote denser budding, increased essential oil production, and higher overall yields.

Does this fixture require a ballast?+

No, this is a ballast-free system. It uses direct bypass LED lamps, which means you won't have to deal with the buzzing, flickering, or energy loss associated with traditional fluorescent ballasts.

How many units can I daisy chain together?+

You can connect up to 3 units on a standard 120V circuit. If you are using higher voltage commercial circuits, you can daisy chain up to 6 units on a 277V circuit.

What is the recommended hanging height?+

For flowering plants with high light requirements, we recommend positioning the light 12 inches above the canopy for a 2'x4' coverage area. For low-light plants, it can be hung at 24 inches for a 3'x4' area.

Can I use this light for the entire grow cycle?+

While this light is optimized for flowering, the dual switch control allows you to manage light levels for different stages. However, for the best vegetative results, many growers supplement with a Sun White spectrum light during the early stages.

Decent watch for the price and very easy to read
Color: Black/Blue, Color: Black/Blue
I would consider this equal to the Timex Easy Reader except without Indiglo and less expensive. It is a nice size with quoted average water resistance. It has a press-down back and mine has a gunmetal color sort of sand blasted finish case. I don't know if it's coated or the actual metal color. The strap which came with it is of the NATO type and of decent quality. In the pic it is wearing the rubber strap from my Vaer watch which is a quick release rubber one. NATO straps are fine if you don't mind the double thickness of strap between the watch back and your skin. The spring pins aren't the typical ones which have the raised parts which allow you to use a removal tool. They are quite difficult to remove but I did it using a box cutter and by applying pressure I was able to eventually work them out and put normal ones on. The strap width is 20mm. I have a bunch of other straps which I can use with this watch. The full face lume is quite bright but I don't know how long it lasts just yet. If in a couple of years it needs a new battery, don't use a kitchen knife to snap off the back, use the proper tool which you can find on Amazon and follow the online tutorials on how to get it back on. All in all it was a good purchase.

Good watch
Color: Silver/Green
This actually a good watch for the price. It glows in the dark due to solar exposure during the day. The wrist band was a little long for my first.

No complaints, attractive, good work horse of a timepiece.
Color: Black/Green
Works great. I gave the luminous face a couple hours under a table lamp. When I went for my nightly half hour walk it glowed green the entire trip. Did not dim out like other watches with luminous hands/digits. So I know it glows for more than half an hour. My 2nd watch from this manufacturer. The other is an infantry watch OD green. Had it for 4 years daily use and still runs great. Changed the batt once. Could not see it in the dark at all. So, this new purchase for nights. I recommend it.

Love This Watch...!
Color: Black/Green
Waiting for a delivery of an expensive diving watch and in need of a watch for my sporting needs, I opted for this as an interim fix. However, it more than filled my need! Nice to look at! (Several compliments received.) Best part is the watch has not lost even 1 second after 3 weeks on my wrist. Never expected that level of accuracy!! While the current band suits the watch's appearance, an upgraded band would fool many into thinking it was far more expensive. Great watch to gift to a buddy...! I would categorize this as a "Best Buy"!

Great timepiece!
Color: Silver/Blue
This is a cool watch! I collect many different styles & price points of watches. There is nothing not to like about this watch. The dial, strap & completely luminous dial make it a great time piece. It's a smart looking field watch that lays nicely on the wrist. $20 is an amazing bargain for this watch. Highly recommend!
