Mars Hydro produces a wide range of LED grow lights in different wattages and formats. While this Mars Hyro review focuses specifically on the 300w LED grow light, many of the features carry throughout the product line. At the end of this review, I’ll also provide information about several other Mars Hydro grow light options.

Features of the Mars Hydro 300W

Easy to assemble

You only need to plug in the cord to turn on the grow light or unplug to turn off. The unit can also be fitted with an auto timer to control the level of light each plant receives per day. For most seedlings, it’s recommended to keep the grow light at heights of between 12 to 30 inches above the plants, according to their needs.

Cutting-edge design

The Mars Hydro 300W fitted with a robust internal cooling system that helps bring down temperatures when they are too high. The frame consists of silent, forced-air intake & exhaust fans as well as sizeable pin-cushion heat sinks that help regulate heat levels, thus ensuring the longevity of the product.

Epistar 5W LED chips

Mars Hydro uses Epistar 5W LED chips to help distribute light evenly for all plants so they can grow at the same rate without some germinating and others withering due to excessive light. These chips have an increased Par value which means adequate light will be absorbed by the plants for proper growth, development and yield.

Full Light Spectrum

MarsHydro emits useful wavelengths of luminosity that can quickly be absorbed by plants to foster the photosynthesis process. The full spectrum range ensures uniform lighting for the plants, which is useful for all stages of germination.

This product was developed following eight years of thorough research and testing, emerging as the most proficient spectrum for plant growth, even outperforming CMH, HPS, fluorescent and induction in similar wattage tests. It’s suitable for growing both vegetables and flowers.
