Make sure of what that MH bulb is putting out. A lot of MH bulbs put out 4000-5500k light. If yours is like that then you will find the Ipower MH lights, which are made to put out 6500k will give better results. but then when you switch to HPS and cut back to 12/12 they will stretch anyway.
they are 72,000 lumens. htg said good match for my setup/ ballasts. they do cause S T R E T C H.. i did try digilux 95,000 lumens. was not impressed for xtra cost. pup, was asking, do u know or think that keeping mh s about 18 inches above plants during last 2 weeks of veg. could cause that(stretch). would lowering lights down to 8 or 10 inches above plants slow stretch at all. thanks bud.. :confused2:
