Suggest Lighting Area: 3'3. Keep tent in good cooling system. Q: What color temperature should I choose?
A: Most customers choose the 3500K color temperature for full cycle usage (both vegetative as well as bloom/flowering). The 3500K color spectrum has a good amount of both blue spectral output (400-450 nM for vegetative growth) as well as red spectral output (600-660 nM for flowering). For flowering/bloom only, most growers opt for 3000K as it has a more pronounced red spectral peak with slightly less blue spectral output, mimicking more closely the autumnal sun spectrum. 4000K and 5000K are good for vegging and also has many applications well suited for young plants.
Q: Do I need a separate light for veg and a separate light for flowering/bloom? A: No, most of our lights (unless denoted) are for full cycle usage, meaning you need only one light for seed/clone/seedling to harvest. We use LEDs which output a very bright white and offer color temperatures designed to mimic those of natural sunlight. Q: Why LED vs HPS?A: LEDs compete with traditional HPS and Metal Halide HID lighting sources in a number of ways, including greater energy efficiency, longer lifetime, and smaller size. They, however, are more expensive.
LEDs operate at a much lower temperature so there are less cooling requirements (energy, noisy a/c and fans) - also, because they put out less radiant heat they can be positioned closer to the plant canopy. The ability to configure LEDs also helps to increase their usability over HPS, which traditionally must be positioned higher - and directly above - the canopy.LEDs can be placed in different configurations above the canopy to suit many different sized growing areas. Q: How is cooling perform without heatsink? This tempreture is Much lower 20? Than Led working should be under 70? Notice: DON'T TOUCH THE BOARD WHEN 288V2 ON LIGHTING.
