I know I'm replying to an old post, but I got to ask what the hell do you guy do to get your plants to branch out so close to the soil I'm in my second grow and my plants grow and stretch badly! I got to figure out what I'm doing wrong!!! I think personally my seedling lighting is great. This year I'm giving LED lighting a try and right now I'm thinking MH/HPS is best in my area because of the cold winters, I have to add a heater to keep the temp up, I can see where they would be great during the warm months, but what is the trick to stop stretching during the seedling stage???
