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.

Husky chew proof....so far
My husky has a habit of gutting and destroying any squeaky chew toy I have gotten for her. This one so far has lasted a over a month now I must say it does make her work for a treat when hidden in the center of it. So far all the stitching and parts are attached and like new. The plastic center where you hid the treats is intact, the firmness of it does make it difficult to get the treats you put in hard to remove-so choose wisely and not put in large pieces as there is one of the first pieces still inside the center as even I can't get it out. So my girl she enjoys carrying it around and playing with it so this chew toy is a win for this husky owner

DANGER
DO NOT BUY!!! DANGER! We have had the turtle ones before and then got these. Be we bought two. there is a plug peice in the end that popped out. My dog ate it the first time and had to have emergency surgery because it was stuck in his intestines. We had it removed which cost THOUSANDS of dollars. Also was on vacation when it happened and had to come early when the sitter informed us he was ill. We felt guilty for month! had he got something in our house or yard was it our faults. We saved what they removed which looked like a cork but we dont drink wine. we have a frenchie that doesnt enjoys long walks on the beach if you know what i mean so would not have had access to eat something other places he doesnt relaly go anywhere. This was his favorite toy for a long time so when it got dirty outside, we threw away the first one and took out the second one to replace it . One day i was sitting playing fetch with him when i saw the plug peice come out. I caught it and took it out of his mouth. I IMMEDIATELY RECOGNIZED IT. I ran to grab the zip lock bag the vet gave us with the cork looking item covered in gunk and slime from inside his intestines, ran to the sink to rinse it off and what do you know. mystery was solved. This toy could have killed my dog !

Strong hold
Color: Multi-colored, Color: Multi-colored
Very good product. I’m definitely impressed. I have two German shepherds and this toy is definitely durable and does what it’s made to do. The suction is great. The company even gives you a clear plastic strip that you can actually put on the floor and then put the suction cup on it For better grip. I’ve had suction toys before which was absolutely horrible. This one definitely supersedes all others. The suction comes off once in a while but usually that’s because if my dogs are literally biting on the suction cup part lol. But with confidence. Great product
