Im sorry man I have no experience with MH or building light boxes.
I was just asking cuz they look alittle lanky but they are only 5 days old you could probably add alittle soil to the top to give them some support. this should only help with the initial growth since she wont have to worry to much about holding herself up.
What kinda soil are you using?
lefthanded Reviewed by lefthanded on . WWM/PP/BB/SSH Hello All, WWM = White Widow Max PP = Purple Power BB = Big Bud SSH = Super Silver Haze This my second attempt. It is the 5th day after germination. I am using better soil and I think the seeds are really viable, I mean the WWM because they germinate in less than 24 HRS and by the third day the stem is almost 20mm long "3 seeds all of them germinted". But not really for the PP, BB, and SSH. Rating: 5
