I started grow in 1980. I have grown indoors, outdoors, grown in soil and Hydroponic. I started with hps lights then added metal haagen. 10 years ago I went Led, from Advance Lighting. I started with a 350 watt and added another 650watt. My room is 8’ by 4’, which I grow 4 plants. From seed to harvest in 12 weeks.Just harvested my first crop after adding new 650 watt. Led light. White Widow Seeds from Ilgm. 9.82 oz off best plant,other three 7 to 8 oz. Per plant. I use only General hydroponics nutrient. It’s a great time in Missouri. By holding a Medical marijuana card, I can grow LEGALLY.
