First and very budget grow -Super Lemon

As the plants got bigger, i got afraid of letting them out in the open and took them inside the bathroom of the empty part of the house. Since i'm not able to count with the sunlight anymore i've got to spent some money on a 360w UFO light, that packed a real nice sprout into the plants, that were getting preeetty tall. There was a day that i swer they grow like15cm, hit the led and burned a couple leaves.
