Lights

Start the led up high around 30 inches and slowly inch it closer each day till you get about 20inches away then hold the hieght their. I find this is the sweet spot for good leds such as quantum boards with samsung diodes. I find feed, feed water works best in most soil or soiless mediums along with alternating the ph one week top of the ph spectrum then the following week ph to the lower end of the spectrum. I find the ph will balance itself to a happy medium the plant loves.
