What is the best LED grow light for small grow tents 2021 Update?
Most of us live in cities nowadays. Stuck in the concrete jungle, we believe that gardening is not available to us. Even growing small plants in pots isn’t possible if you have a small balcony. And having a backyard garden for most sounds like a dream.
small grow tents are great for growing seedlings, succulents, fruits and vegetables in a small controlled indoor environment. These small sized grow tents are typically three to four feet high instead of the five to seven foot height of a full sized grow tent.Lights, smell, and watering all stay within the tent. In other words, the shelter makes you the god of your own garden, in the comfort of your own home.
There is a limited range of quality small LED grow lights in the 50 watt to 150 watt range for small grow spaces of 2ft x 2ft or 60cm x 60cm.
LED grow light efficiency
Dividing the usable PAR output of the LED grow light by its consumed power (watts drawn from the wall) we can calculate the efficiency of the fixture in PAR output per watt. To achieve a high system efficiency the grow light must use the best power supplies (LED drivers) and a high quantity of LEDs (LEDs run more efficiently when each one is run at lower current, more LEDs per watt = higher efficiency). So higher LED grow light efficiency is a very strong indicator of a high quality fixture.
Higher LED grow light efficiency also means lower heat from the fixture. Heat is a result of low efficiency where the LED drivers and lights will run hotter and increase the temperature in the grow area. This is a particular problem when growing in a small grow tent as more heat means running fans and AC at higher speeds to remove the heat resulting in more fan noise and odour leakage. Higher efficiency = more stealthy growing.
Let's introduce the actual wattage LED grow light suitable for small grow tents on the market!
