Hello Coldpressed I always start mine under a 400 watt MH.

You're growing in a closet so heat may be a bit of a concern for you, I tend to have the opposite problem ...... cold .

You can move the light up to "five feet", if you have to keep it far away then streching can occur so be ready to offer a little support to the seedlings

mand Reviewed by mand 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
