HB-660 LED Grow Light Product Description:

Be confident that you will increase your yields and crop quality with this super bright LED grow light, HB-660! HB-660 is a full spectrum LED grow light meant to provide enough uniform light for a 4’ x 4’ grow space. It features quality components and has some features that make it stand out in the market.

The HB-660 draws true 660 watts from the plug. It is supposed to have an equivalent light output of a 1000-watt HID bulb. The PPF is rated at 1716 μmol/s with almost every photon absorbed by the plant and efficacy at 2.7 umol/J.

HB-700 uses the quality white diodes designed by Cultiuana which cover a wide spectrum of PAR and produce more intense light with fewer watts. It also incorporates the most efficient Osram 660nm diodes that create an ideal spectrum for vegetative and flowering stages.

However, strong and efficient light isn't the only thing Cultiuana is going for. We know uniform coverage is what every grower cares about most when shopping for an LED grow light. To achieve this, our engineers used 8 bars with a foldable design to spread the light evenly over your canopy, including the lowest parts, and algorithmically placed diodes to create a great uniformity of coverage. So with a single light, it's easy to cover all angles of your grow area evenly.

When you check the PPFD chart, you'll see that in a 4×4 growing surface area, the average PPFD reading is 1138 μmol/m2 from a height of 12 inches. It stays consistent in literally every part of the surface area, even when hanging at a low height, it ensures the contribution to the edges and corners.

The onboard dimming knob is accurate in the PAR ranges. It has preset options for 40%, 60%, 80%, 100%, and external control. So by dimming up or down the light, you can fully control the efficiency at any given time.

Have a larger growth? No problem, as 50 lights can be connected through the daisy chain ports and controlled by a single dimmer or controller.

The HB-660 truly doesn't get hotter than the stated maximum operating temperature of 113°F/45°C. The passive cooling mechanism is designed very effectively with heatsinks, so you probably won't need any active fan to cool down the light.

We offer a 7/24 online service, a 5-year limited warranty, which is about the industry average, and a free return for an exchange/replacement.

Large capacity and great price! This is a steal!
Size: 6.0 Qt, Color: Linen Gray, Size: 6.0 Qt, Color: Linen Gray
I bake a LOT of sourdough bread, and this dutch oven is a super heavy-duty cast iron with an enameled finish. It's flawless and spreads the heat evenly when baking. The clean up is easy--I just spray a touch of dish soap and use a damp washcloth to rub it clean. Rinse thoroughly and allow to air dry. I put a touch of oil around the exposed rim to keep in seasoned and rust-free. The lid knob as well as the side handles make this easy to handle and helps distribute the weight when removing it from the oven. The included rubber rim protectors are a nice touch, and I use that on all of my cast iron when storing them away. The price on this is amazing for such a large 6-quart capacity. I find this to be a super value and would highly recommend this Dutch oven.

Fantastic Dutch oven. VERY thick and heavy and cooks really evenly because of that.
Size: 6.0 Qt, Color: Olive
This thing is fantastic!! SUPER heavy-duty Dutch oven...it weighs almost 2x as much as my other Dutch oven which shows how thick the cast iron is beneath the enamel. It is absolutely solid and heats up nice and evenly on the stove top. The ceramic surface inside of it is really nice and fairly non-stick. I've cooked Curry and meatballs in it so far and cleanup was easy for both even though the meatballs burned a little on the bottom (I forgot to check on them and walked away). I haven't tried it with bread yet, but I can only assume it will work great for that as well because of how evenly it cooked my other foods. This has become my favorite Dutch oven even though I have one that cost almost 2x as much. (this one is thicker, heavier, and cooks more evenly than that one). I cannot recommend it enough.

Even heating and great for sourdough.
Color: Dark Blue, Size: 6.4-Quart - Deep, Color: Dark Blue, Size: 6.4-Quart - Deep
This enameled cast iron Dutch oven is a fantastic addition to the kitchen. It is a very nice, well-constructed piece of cookware that performs exactly as it should. The heat distribution is impressively even, which eliminates hot spots and makes it great to cook in for everything from slow-simmered stews to searing meats. One of the areas where it truly shines is baking bread. It handles the high temperatures required for a professional-style crust perfectly. The lid seals in steam effectively, which is excellent for getting that ideal rise and airy interior. It has become my go-to for making artisan loaves at home. The enamel finish is durable and makes cleanup a breeze since food doesn't tend to stick to the surface. If you are looking for a versatile pot that transitions seamlessly from the stovetop to the oven, this is an excellent choice. **Pros:** * **Even heat distribution:** No hot spots while cooking or simmering. * **Excellent for bread:** Retains heat and steam for a perfect crust. * **Beautiful and durable:** The enamel finish is high-quality and easy to clean.
