The MarsHydro Reflector fits much better in a small square 4’ by 4’ grow tent than many of the rectangular panels we’ve reviewed. We noticed some slight singing when we used the “flower” setting, but there were no such problems with the “veg” setting – one of the perks of an adjustable spectrum. Those with other lights in consideration will probably prefer to use this one as a back-up light, but it definitely excels when compared to less expensive options.
LED Grow lights
For small- to mid-size growers, you’ll need to get the most for your money. Since you don’t have the budget of the big-time growers, you don’t want to drop all your cash on a single light. This is where the G8LED 450 Watt LED Grow Light comes in. It’s still a bit on the expensive side, but it’s a great choice for one of your first upgrades.
This light covers all 8 bands of the visible light spectrum plus infrared, making it an effective panel to cover all your needs. Its big brother, the G8LED 600-Watt was named “Best LED Grow Light” by High Times.
For those who love the P600 but don’t have quite that large of a budget or size of a grow tent, the Advanced Platinum Series P300 is a great runner-up. This is definitely a more affordable LED grow light that offers many of the same benefits as the P600, but at around half the price.
Its coverage is about 4.5 feet by 3.8 feet at an 18-inch height, perfect for compact grow areas, or when used in combination with additional lamps for larger areas. This light panel effectively replaces a 400W HPS light, while only actually using 180 watts of power – making it an energy efficient alternative to a traditional light. It’s just perfect for the small home grower. Just as the P600 represents the higher end of the market, this is still a serious piece of equipment–practically a steal for the amazing coverage you get.
This is a system that has a great high PAR per Lumen output of any other LED grow light panel I’ve seen. What does that mean? Well it means the panel gives off about 2 to 3 times the intensity of other grow lights.
More importantly, it has an 11 band spectrum that gives your marijuana plants the most nutritional value including those needed from UV and IR. The light chips are all 3W LEDs, and as I’ve mentioned before, the best 3-watt panels have an additional lens to focus the light a bit more. This panel comes with a 60-degree lens and secondary 90-degree focusing lens to give more intensity for plant growth.
The chips in this lamp are also replaceable and another reason for the slightly higher price tag. This means you can always keep that 400-watt output, even when a chip blows. Just order the one chip and replace it when it arrives from the manufacturer. With a 5-year guarantee, PlatinumLED offers security to their customers.
All of the Advanced Platinum Series from PlatinumLED grow lights use revolutionary full-spectrum technology to keep your grow room and plants cool while meeting all their light needs. The P900 offers their trademark “3x intensity” lights that offer three times the brightness that competing LED grow lights have.
The P900 has 12 bands of light wavelengths including infrared and ultraviolet, the parts you can’t see with the naked eye. This panel, and others like it in the Advanced Platinum lineup, is about as close to sunlight as you can get indoors. But this isn’t a one-trick pony. This panel is good for every stage of growing cannabis.
You can keep it low-key for sprouting by hitting the “Veg” switch, or kick up the intensity by flipping the switch for “Bloom.” The 90-degree angle of the LED focusing lenses sends the light down into the canopy of your plants. This encourages massive growth.
It can replace a 1000-watt HPS light at full intensity and still only use 515 watts of electricity. The average price of electricity in the US is around 12 cents per kilowatt-hour. Running a 1000-watt HPS costs you 12 cents every hour, plus what you’ll pay to cool it. But running the P900 gives the same or better light quality and intensity at half that price.
When the P900 is suspended at 18-inches above the plants, its core coverage reaches up to 3 by 5 feet. Its maximum coverage is 4 by 6 feet. You may be asking what those numbers really mean for you. At different stages of growth, you’ll be raising or lowering the light according to what your plants need. For sprouting, you can cover up to 4 by 6 feet. But at more intensive stages like flowering, you’ll cover less area because you need more intense light. An adult cannabis takes up at least 1 square foot of space in a 3-gallon pot, so the P900 can flower between 12 to a maximum of 24 at a time.
This definitely isn’t a budget light system. But we like that the P1200 LED drivers work anywhere in the world. They accept 110V or 220V input (or specifically, 85V to 260V.
