Avoid heat build-up with LED grow

Modern LEDs generate less heat - but not none. Without air exchange, heat can build up directly under the LED panel. Solution: Check the distance, optimise air circulation, install additional exhaust air if necessary. LED drivers also generate waste heat - never install them in the box. Measure the temperature at the height of the tips, not on the tent floor. Correct air routing prevents heat build-up, even with modern LEDs.
