The effect of the permanent markers is incredibly strong. After vaporizing, I'm done for the day. The plant with the recycled soil and our refresh fertilizer did well. The other one in the t.a. peat-free soil had some initial problems but then developed properly. Neither yielded huge harvests, but the flavor is solid and, as I said, the effect is very strong. However, my total average lamp consumption was only 120 watts in total.
