I started mine 2 to 3 feet under a 400W hps, not directly underneath, but a little off to the side. All 8 of 8 seeds sprouted. Later I switched to a MH conversion bulb with better veg results.
notanotherteensmoker Reviewed by notanotherteensmoker on . Can I start my seeds under a 400 MH? The temp in my closet is running from about 78-81 and I have enough room to move them up to 5 feet away if I need to diminish their exposure to it. Thanks in advance for any input. ;) Rating: 5
