Latitude: the geographic position North or South of the equator

Leaf burn: when a plant receives too much light or spends too long in direct light, this can occur causing the plant to turn yellow and not perform photosynthesis

Leaves: where plants perform photosynthesis and release oxygen

LED grow light: (light emitting diode) use energy through a semi-conductor to produce light, need more wattage to function than normal LED lights

Vita™ LED Grow Light

LED normal light: same as above; will not provide sufficient light spectrum to plants for successful growing

Longitude: the geographic position East or West of the Prime meridian

Lumen: a unit of measurement for the brightness of light

Metal Halide (MH): similar to HPS except these use metals and halides for the reaction in the arc, these produce blue and white light

Mounting bracket: bracket on which to mount something to a wall or ceiling

Node: an area right below where a leaf or branch comes out of the stem

Nutrients: usually found in the soil and absorbed by the roots, plants use this to survive and grow

Orchid: perennial flowers that usually bloom in vibrant colors such as white or pink

Outlet plug: how a light will obtain power, is mobile to anywhere near an electrical outlet

Outlet timer: a timer that will turn itself on and off saving you time and money on your energy bill

Photosynthesis: the process by which plants take carbon dioxide, water and light and convert it to oxygen and glucose

Photosynthetically active radiation (PAR): visible light radiation that allows the plant to perform photosynthesis

Power supply: supplies power to the light fixture

Photosynthetic photon flux density (PPFD): the amount of photosynthetically active photons that fall on a surface of a plant in a certain amount of time

Photosynthetic photon flux (PPF): the total number of light photons released by a light source

Roots: a structural feature of a plant, it anchors the plant in the soil and collects water and nutrients for the plant to use

Seedlings: the first part of a plant that protrudes out of the soil

Stem: a structural feature of a plant, it allows the plant to stand up and keeps the leaves as close to the sun as possible

Soil: a mixture of organic matter, minerals, nutrients and gasses where plants are located and anchored to by their roots

Light is perfect, timer is not

The light is so beautiful! Extremely sleek and feels very solid, like a quality fixture should. I ordered the large white version, and the wood arm so I could attach that to the wall rather than fuss with the hardware and hook it to the ceiling. (I'll avoid drywall anchors at all costs, but it's great they were included). My plants are happy, and I'm thrilled with how it looks in my home! Only issue I've had is with the outlet timer - it just doesn't work. The instructions aren't complicated, of course there's always a potential for user error but there's only so many switches that can be flipped and I've tried all directions with no success. Admittedly its rather frustrating, since I'll have to figure something else out if I'm not home to turn the light off and on..

Working very well

We’ve been using our lights for 8 months now and really like their appearance and function. Great product.

I recommend this product

So far so good.

I’m writing this review for the 10% off. I’ve just received these lights, but after a week of use they seem to be working well. They are certainly more attractive than the average grow light and give a very nice ambiance. I’m not quite sure they are worth the cost, but I would probably still recommend these to someone who wants a visually pleasing grow light.

Awesome Light

This light is beautiful and effective. My monstera is already growing faster!!
