This light was easy to use, great light but very, very narrow light focus in the center even tho it's a long, thin shape. I upgraded to Mars Hydro TSL2000W after this but I am still going to use this for 1 plant. If you want to grow photoperiods, only grow one but could probably do fine on 2 autos that don't have to grow very big or develop a big footprint.
