This cannabis grow journal uses our TLM400 – 400 Watt LED Grow Light. The grow tent is 4′ 8″ x 4′ 8″ square by 7′ high. Plants were started in 4″x4″ Grodan rockwool cubes from seed of unknown strain. After sprouting at the beginning of December 2013, they were placed in a simple ebb and flow hydroponic system.

3 Weeks From Seed – 12/29/13
Plants were topped at 2 weeks and are bushing out nicely. They stand about 10-12 inches tall and are about 16 inches in diameter. Important to note in these images is the spacing between nodes. Our lights help produce many more bud sites than our competitors as noted by the tight spacing between nodes. You will notice that spacing between nodes is no more than 2-3″ and that every node represents a future bud site. In this setup, power distribution is about 25w per square foot in a 4×4′ space.
