Complete with a combination of high pressure sodium and metal halide bulbs, the Yield Lab 400W HPS+MH Air Cool Hood Reflector Grow Light Kit is a fantastic setup for growers looking to grow plants indoors and all year round. Offering a greater level of control over growing conditions, the Yield Lab air cool hood reflector kit includes:

  • Yield Lab 400W High Pressure Sodium (HPS) Bulb – 1 year warranty: With 30% more blue color wavelengths, the HPS bulb assists with the process of photosynthesis and stops plants from shooting up too fast (which results in spindly stems). The Yield Lab 400W HPS bulb is suitable for all Heliophile plants which prefer longer periods of sunlight, including camellias and roses.
  • Yield Lab 400W Metal Halide Bulb – 1 year warranty: With a color temperature of 5,500K, this metal halide bulb is best suited to the vegetative stage of the plant growth cycle. The Yield Lab metal halide bulb is an optimal choice for plants in the propagation stages and is particularly suited to lettuce, herbs and other green, leafy plants.
  • Yield Lab 400W Digital Dimmable Ballast – 3 year warranty: The stand out feature of this digital ballast is the dimmer control which allows the heat output to be significantly reduced on warmer days. The dimmable feature also allows for greater control of lumen intensity, with the ability to increase output in the latter stages of the growth cycle. The inbuilt safety features protect growers from overheating, ignition failure and both open and short circuit issues.
  • 6” Yield Lab Air Cooled Reflector Hood – 1 year warranty: The air cooled reflector hood is constructed from galvanized steel with a protective powder coating to guard against corrosion in humid environments. Manufactured with sponge seals surrounding the lens cover, the 6” Yield Lab reflector hood is 99.99% airtight and has been especially designed to increase airflow for improved cooling function.

  • Complete Digital Installation & 12 Week Grow Guide: Each Yield Lab Grow Light Kit comes with an easy-to-follow installation guide that walks you through setting up and using your brand new grow light. Our 12 Week Indoor Grow Guide will show you how to maintain a healthy indoor grow room including lighting and feeding schedules, pH and PPM levels, and optimal environmental conditions like temperature and humidity.

The Yield Lab HPS+MH air cool hood reflector grow light kit includes 1 x HPS bulb, 1 x MH bulb, 1 x digital electronic ballast, the air cooled reflector hood , ceramic socket, a hanging ratchet kit and a free timer .

Will buy again !
I recently got this bamboo cutting board set and I’m really happy with it. The set comes with multiple sizes, which makes it super convenient for different tasks—smaller boards for quick prep and larger ones for bigger meals. The built-in grooves are a great touch, helping catch juices and keep the counter clean. The boards feel sturdy and well-made, but still lightweight enough to handle easily. I also like the natural bamboo look—it adds a nice, clean aesthetic to the kitchen. The included stand is a bonus, keeping everything organized and easy to access. Overall, this is a practical and stylish set that works great for everyday use. Definitely a solid value and something I’d recommend to anyone looking to upgrade their kitchen essentials.

Beautiful Acacia Boards That Actually Feel Premium and Thoughtfully Made
I’ve gone through a lot of wooden cutting boards over the years, and these immediately stood out as feeling much higher quality than most sets in this price range. The acacia wood has a really rich, attractive grain pattern and the boards arrived smooth, solid, and well finished with no rough spots, cracks, or cheap “composite wood” feel. What initially caught my attention was the fact that these are marketed as non-toxic and free from mineral oil. Most people don’t think much about what wooden kitchen products are treated with, but I appreciated that these use a natural blend instead of petroleum-based mineral oil. The boards had a very clean, natural wood smell out of the box instead of that chemical/oily smell some cheaper boards have. The three-size setup is honestly perfect for daily kitchen use. I find myself constantly rotating between them: the large board for meal prep and meats the medium board for vegetables the small one for fruit, cheese, garlic, herbs, etc. The engraved food icons are also a surprisingly nice touch because they help keep things organized and reduce cross contamination without looking tacky. A few other things I really liked: They’re lightweight enough to move around easily but still feel sturdy - The wood is gentle on knives - The groove catches juices well - They look nice enough to double as serving boards - Packaging was clean and plastic-free/minimal Like any real wood cutting board, you absolutely need to: - hand wash only - dry them after use - occasionally recondition the wood If you expect dishwasher-safe convenience, these probably aren’t for you. But if you want attractive, natural wood boards that feel healthier and more intentional than cheap plastic boards, these are excellent. Overall, these feel like a genuinely thoughtful kitchen product rather than generic mass-produced boards with a trendy “eco” label slapped on them. Very happy with them so far.
