The Mars Hydro SP 3000 300W LED Grow Light can accommodate up to a 2.5' x 5' area for flowers and 4' x 5' area for vegetative growth. Mars Hydro has made a name for itself in the grower's community. Mars Hydro is renowned for providing LED grow lights that are both affordable and of high quality, as well as offering fast shipping and excellent customer service. They have a strong presence in both the EU and the US.
The Mars Hydro SP 3000 is the successor to the popular former SP3000-250 and comes equipped with a range of advanced features that make it an ideal tool for indoor growers seeking reliability, effectiveness, and durability. Notable features of the fanless grow light include a full spectrum of LEDs, a waterproof body, and the potential to increase yields by up to 50%.
Mars Hydro SP 3000 Features
The SP series of LED grow lights by Mars Hydro was designed by their expert designers with a focus on delivering high efficiency and top-notch performance. The device comes packed with various features that make it a superior choice for growers. The full-spectrum grow light provides coverage for all essential wavelengths of natural light and sun, which emulates the natural light made from the sun. Additionally, the grow light features removable drivers that help reduce the heat output.

Hanging Height
According to Mars Hydro, the recommended light intensity settings for brightness when the red light and hanging the light 12-18 inches (30-45cm) above the canopy are as follows:
-
Clone stage: 30%
-
Germination stage: 30%
-
Seedling stage: 50–75%
-
Vegetative stage: 75–100%
-
Flowering stage: 100%
This feature offers a high degree of versatility, making it a popular choice for many growers. One of its main advantages is that it allows growers to adjust light intensity of the lighting to suit the various stages of growth without having to switch lights or worry about the potential stress or bleaching that can be caused by certain types of LEDs.
Removable Drivers
Although LED lights offer the significant benefits of lower operating costs and less heat generation, even high-powered models like the SP3000 still produce some heat. However, Mars Hydro has addressed this concern by incorporating a power supply with a detachable driver in the SP3000. This self-contained power supply efficiently manages the energy required to power the LEDs, generating most of the device's power supply without heat.
With the driver easily unscrewed and placed outside of the growing tent, growers can keep the driver connected using the long extension cord, which helps reduce the heat output within the growing space. This low heat output is a significant advantage, particularly for those who have smaller grow tents and struggle with low heat output and management. It's a standout feature that sets the SP3000 apart from other grow lights.
Daisy Chain Function
The SP3000 is a suitable choice for both large-scale home grows and commercial operations due to its daisy chain function. Up to 20 lights can be connected together to form a daisy chain that is controlled by a single dimmer switch, providing a high level of consistency when managing multiple plants. While each light still requires its own power source, the ability to control them all from a single switch can save a considerable amount of time for growers.
Light Coverage
During the seedling and vegetative phases, the Mars Hydro SP3000 emits light at an appropriate intensity for a growing space of 2 x 4ft (60 x 120cm). The PAR output of light measures light emission within the photosynthetic range. The full spectrum of light-boosted red SP3000 produces a PAR of 741–999µmol, with the dead center of extending light out being 999 and some of the corners of full spectrum dipping down to the lowest point.
