Not Applicable for this grow. But this has proven to be an excellent product. Handles a 4 x 4 area perfectly. (I have 5 x 5 ) just a little drop off. You can still grow some great weed and fill a 5 x 5 with this light. Great light to step your game up or to enter the fun world of growing. I will give this product a 5 star rating if it lasts another year. That will be 3 years of constant use.
