Here's a pic of my grow room. Its 8'x12'x4' high. Its fully conditioned with a return air to finance, a small ceramic heater/fan and keeps the space around 74 degrees. Soil is just under ph of 7. I started with 2 4' grow lights, (totally insufficient). On 10/10/18, I started 2 bubblicious autos. They started tall and thin. From your website, it told me to add additional, closer lighting, the 2 reflective domes you see, with 2 each LED daylight bulbs each, 800 lumens, 5000Kelvin. (Forget wattage, these are LED) The plants responded well and I believe are entering flowering stage. I have replaced 2 of the bulbs with 1270 lumen, 2800Kelvin. In total I have left the 2 4' grow lights, have 2 LED blue spectrum, and 2 LED yellow spectrum lights. I have been using LST. The far plant has 15 cola. Will I be okay at harvest. 1st time grower.
