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.

Basic mouse that works - - for now.
Size: 1 Pack, Style: USB Receiver, Color: Blue
I ordered this mouse (in blue) to replace the recently deceased exact same model that I've used for the past 2 or 3 years. I like the simplicity of the M185 mouse and mostly the best bang for your buck! I caught this one on sale for less than a ten-spot, so I thought, "why not." I'm hoping that this one will last a bit longer than my two previous M185 models, that averaged about 3 years each. This model seems plagued by a short life span and is predisposed to mysteriously and suddenly dying, without any obvious symptoms or warning of any kind - - you're working and clicking along, going about your day, when suddenly the cursor on the computer screen freezes and that's it. Nothing, zero, nada. Funny thing, I'm very careful not to abuse or drop the mouse, and keep a fresh battery installed and watch for leakage and all that stuff - - they just stop working, and I assume it is caused by some sort of inherent electronic fault in the circuitry of the previous M185's. Due to my loyalty to the brand and model (and since it was on sale) I decided to give it one more shot. They say that "third time's a charm". I like the fact that the M185 is simple and uncluttered with extra buttons that I would never use for my purpose, which is simple web-browsing and the occasional text document production. The feel is solid, not heavy, but not cheap feeling, either. I'm used to the shape of this mouse, which to me is quite comfortable for long sessions, another reason why I kind of wanted to stay with this model. The buttons have an audible "click", which doesn't bother me at all, and the wheel moves smoothly and also has a clicking operation (which I rarely ever use). The overall surface of the mouse has a matte finish, but like my previous models I'm sure it will eventually wear shiny spots where my fingers reside and will attain a more "well-used" look in time. Connecting it was a breeze, too. I just plugged the dongle into a spare rear usb port of my desktop, and the mouse connected instantly, no problem. The dongle can be stored safely inside the battery compartment, so you can take the whole thing out of the house if needed for use elsewhere. The speed of 1000 dpi seems just right for my purposes. The one I ordered even came with its own AA Duracell battery, which I wasn't really expecting. This mouse also enters "sleep mode" when you don't use it for a while, and I can't say how many times I've got up and left it on all night. And that's not hard to do, as I'll explain next. The only real negative to this mouse is the absence of any easily visible status indicator of it's on / off switch. The rear housing of this mouse is matte black, including the tiny switch where you turn it on and off with your fingernail, with only a very faint "on" lettering (also black), and very hard to see with my aging eyes. The laser is not lighted or visible when on, also adding to the confusion, especially in a darkened room. So, as a workaround, I took a tiny drop of green paint and placed it down inside the switch slider to visibly help indicate the "on" position, and likewise a dot of bright orange for the "off" position. Many of Logitech's more expensive models (and a few other manufacturers) include this color-coded switch indication. I guess for the $$, they had to cut corners somewhere - - a minor complaint. In summary, this is a good basic mouse that works - - let's hope that this one will last longer than its two predecessors.

Dependable, Reliable
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey, Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
As advertised. Logitech, best mouse for your hard-earned cheddar! It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse. So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it! 😉

Hey, it works well. Just plug it in and you are ready to go. Only issue, minor, no light or color coding on back to indicate on or off.
