Has anyone used this light Kind LED K3 Series L600 LED Grow Light
If so is it any good for a 1200 x 1200 cm tent.
Also is it controllable ?.
Thanks in advance for your answers.
Welcome. I'd go with a few more watts and adjustable. You don't have to use max power, but it's nice to have, if you can use it. You could also go with 2 Mars SP250 or the like, and use 1 for veg, and both for bloom. I'm new to LEDs, though, so others will chip in. The concept of passive cooling on quantum boards is cool.
