High Pressure Sodium lamp with clear tubular outer bulb, high output and long reliable lifetime. High Pressure Sodium lights produce an orange/red spectrum and is best for flowering plants. The orange-red light stimulates plant hormones and encourages it to flower. The best way to light your grow room is with a combination of blue and red/orange light, to keep plants compact and flowering happily. This is best done by using a Halide then changing to a Son T style HPS or by using a multi-spectrum lamp. Plant growth (photosynthesis) is not then determined by lux or energy, but by the photons from the blue to red (400–700 nm) part of the spectrum. This is called growth light! Extremely high quality sodium bulbs that produce slightly more lumens than standard models and last much better than the competition.

  • It contains photons that can be measured in terms of energy.
  • This 400W bulb is generally placed on top of the greenhouse, and used to help the climate and humidity control.
  • These lamps are developed for maximum growth light, and are the most efficient light sources available for horticulture.

Good overall
Color: White, Size: Standard (Pack of 2)
Bought these for our guest bedroom. They are quite overstuffed, so if you like full pillows this will be your thing. As such they are dense and firm. The height is a bit much if you are small framed, but are comfortable overall and stay cool enough to be nice in the summer.

Finally Found Pillows Everyone Loves
Color: White, Size: King (Pack of 4)
I LOVE these pillows. I bought the king-size set and ended up liking them so much that I want them on every bed in the house. They’re soft but still supportive, and they actually work for different sleeping positions, back, side, and stomach sleepers. They don’t go flat, but they’re also not overly stiff, which is such a hard balance to find. I throw them in the washing machine which makes them super easy to wash! The size is true to King! They feel cool and hotel-quality, and the down-alternative fill is great if you don’t want real feathers. I wake up without neck pain, and they keep their shape night after night. If you’re picky about pillows (like I am), these are absolutely worth it. Comfortable, affordable, and a great value for a set of four.
