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.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.

Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.    HRV, readiness & total sleep score metrics increased drastically this week.  See screenshot :) Support: Molds and cushions every crevice under my neck and above shoulders. So comfy  Size: Adjustable loft but king length is perfect to hug and rest your head.  Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated..  my Oura ring showed both nights I was awake every hour.  Not good.  Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep.  Huge. Weight: Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders Softness: Like the baby bear.. just right.   Comfort: Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.  If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size
