This week I switched up the lights. I had been using 6500k T5 bulbs that a friend gave me for free. I planned on changing two of the bulbs to 3500k when she went into flower but I could not find the right length in the 3500k. I decided to purchase a Parfactworks led. I installed the light on day 32 and transitioned her to the new spectrum. She is LOVING it! :D
