? for experienced growers. 2 lights running. Plant...

Hello, Yes your Girls are stretchy, a bit to much . Stretching means always they dont get enoughLight.or the Qualitiy of light is not enough. Normally i would say 600 w Hid would be enoughfor them to grow nice and dense . If i look at the pictures everything seems to be good. BUt your plants show lack of light.check your parmeters ( really 600 w=?), maybe change the Bulbs .Happy growing

That's relative. But they do look stretchy; the problem here it's the distance to the bulb, 20 inches is too far making the plant get only a small amount of light, thus the stretch trying to reach more light. You can either place the bulb closer, hoping not to cook the seedlings or veg with other light that does not give that much heat. Check my diary #2 High Level, I vegged with Screw in LED bulbs, they give almost no heat, and before flower the plants had 9 nodes in 6 inches.
