distance wise? for seedling and vegi? I have them now at 4.2 feet from the soil with full force from the COB since yesterday and they seam to like it.Start them off under half the lights then turn up after they've settled in.
Have a look into special queen #1 take's around 9 to 10 weeks... It's not a lemon thoughStill have all lights on half till a few weeks before I flip then they'll blow up...I've already got my cutting spots pics for taking more exo cuts. Any old heads have any lemon cuts with short flowering n decent yield., or recommend a bean fitting to that description 8-10 weeks preferred
