I have 3 things going on in my room. Some autos in soil...some in coco...and my mothers and veg photo period plants are in there also. I have them under spider farmer SF 4000. Im about 45 inches over the canopy at 20% im seeing stretching for sure and im worried my underneath nodes are not getting light yet ive been fighting light bleaching for awhile. Its more the autos in soil then anyone else for some odd reason. So i moved out as many as i could but i cant turn up my lights. 12 spfs in a 10x16 size room. Any suggestions??
