I use jacks in a 36 light room. Just cropped out 65-70 lbs.
my recipe :
Hydropro-270g
Cal nitrate-360g
Epsom salt-50g
(100gallon) ppm will be 1400-1500
Do bloom feed first three days of weeks 1,3,5.
stick in a cup of water by the window. it will get roots eventually. trim half the bud sights off and let it sit there. it will die sitting in just soil
