How to choose the right size MH/HPS grow light for your grow room
250W MH/HPS grow light
Coverage Area: 2′ x 2′ (0.6m x 0.6m) up to 2.5′ x 2.5′ (0.8m x 0.8m)
How Far From Plants? Keep 10+ inches (25cm) away from tops of plants
Average Yields: 125 – 250 g (4 – 8 ounces) – less for beginners, more for the pros – get the biggest yields by filling the entire grow area with a wide even canopy and remember that the strain (genetics) you grow with also makes a huge difference in your final yields
Notes: Some (but not all) 250W MH/HPS have a “Built-In Ballast,” which means everything is actually attached together and you just plug the light directly into the wall. Some 250W HPS lights have a traditional ballast, which means that the ballast is a separate piece from the hood/reflector. In general, it’s better to get a light where the reflector is separate from the ballast – they are more efficient, cooler, and spread their light over a bigger area.
400W MH/HPS grow light
Coverage Area: 3′ x 3′ (0.9m x 0.9m) up to 3.5′ x 3.5′ (1m x 1m)
How Far From Plants? Keep 12+ inches (30cm) away from tops of plants
Average Yields: 200 – 400 g (7 – 14 ounces) – less for beginners, more for the pros – get the biggest yields by filling the entire grow area with a wide even canopy and remember that the strain (genetics) you grow with also makes a huge difference in your final yields
Notes: 400W is one of the two most popular sizes for small-scale growers (along with 600W). A 400W grow light runs relatively cool compared to most other HID lights, but packs quite a punch when it comes to yields. Generally it’s a good idea to set up an exhaust for a 400W grow light to manage temperatures.
600W MH/HPS grow light
Coverage Area: 3.5′ x 3.5′ (1m x 1m) up to 4′ x 4′ (1.2m x 1.2m)
How Far From Plants? Keep 16+ inches (40cm) away from tops of plants
Average Yields: 300 – 600 g (10 – 21 ounces) – less for beginners, more for the pros – get the biggest yields by filling the entire grow area with a wide even canopy and remember that the strain (genetics) you grow with also makes a huge difference in your final yields
Notes: 600W is one of the most popular sizes for small-scale growers (along with 400W). A 600W grow light is the most efficient of all HID lights, which means it produces the most amount of light per watt of electricity. To prevent heat problems, I would not recommend getting a 600W light for a regular grow room without installing an exhaust setup or some other way to control temperature.
1000W MH/HPS grow light
Coverage Area: 4′ x 4′ (1.2m x 1.2m) up to 5′ x 5′ (1.5m x 1.5m).
How Far From Plants? Keep 21+ inches (53cm) away from tops of plants
Average Yields: 500 – 1000 g (17 – 35 ounces) – less for beginners, more for the pros – get the biggest yields by filling the entire grow area with a wide even canopy and remember that the strain (genetics) you grow with also makes a huge difference in your final yields
Note: 1000W is the biggest standard HID grow light size. A 1000W grow light is extremely powerful but can also get very hot. To prevent heat problems (which can adversely affect your plants), it is important to set up an exhaust setup or some other way to control temperature.
Gavita 906088 Pro 1000e
The Gavita 906088 Pro is considered the best HPS light in the market at the moment. It comes with a classic designed hood, and a dimmable ballast, which capable of adjusting between 600W to 1000W.
PROS
Uses universal voltage, 110v to 240v current.
With the use of the dimmable ballast, output can be controlled from 50% to 115%.
The unit can be daisy chained with other Gavita 906088 and connected to the controller. Up to 80 fixtures can be controlled by the Gavita Master controller. This saves the user the cost of timers and cables/contactors.
With the use of the Gavita Master controller, up to 80 fixtures can be connected via daisy chain and controlled by one controller.
The eSeries fixtures are plug and play and come with their own control cords.
CONS
Requires ventilation, as it generates heat during operation.
There are instances of bulb arriving broken due to mishandling during delivery.
ECO FARM 400W HPS/MH COOL TUBE REFLECTOR GROW LIGHT SYSTEM KITS
If you are in search for a complete HPS grow light system, look no further than the ECO Farm 400 Watt HPS Grow Light.
The entire system comes well-packaged and in working order. The two bulbs are functioning properly, but the timer is a little bit confusing.
The digital dimmable ballast is quiet and does not buzz. The only noise that comes from the ballast is the quiet small fan.
The digital dimmable ballast can be adjusted at 50, 75, and 100 percent for maximum efficiency. You get more lumens than you would with a magnetic ballast.
The bulb is rated at 400W with a color temperature of 2100K. The generated light spectrum is not only optimized but also delivers high photosynthetic active radiation for healthy plant growth.
This ECO Farm HPS grow bulb comes with a wing reflector, which produces no refraction and has the best coverage for a grow room.
Moreover, you can customize your own setup. First, you can set up the HPS bulb, digital ballast, and reflector. Second, you can set up the HPS and MH bulb, digital ballast, and reflector.
PROS
Bulb is UL listed and CE certified
Digital ballast is quiet and dimmable
Zero acoustic resonance and less power loss
Flicker free lighting that will last longer
Microchip programming allows for easy conversion between HPS and MH bulbs
Design has no exposed wires
CONS
Wing reflector makes temperature control difficult
MH bulb may fail to ignite
