Optimal Light Distance for a 400w CMH bulb?
High all, I'm on my first grow ever using a 400w CMH bulb, thanks mainly to this great thread which I've been reading since the beginning. I've seen the question asked a few times but never really stumbled upon a definitive answer....
What is the optimal distance for a 400w CMH bulb from the plant canopy?
I'm currently running mine about 6-8" from the tops and it seems to be doing fine.. however, to add a complication,
I am about to go away for 5 days so I was wondering how high should I raise the light before I leave? Is there a distance that would be too far? I just flipped the switch to 12/12.
Here's a pic of my setup... I'm growing HGS Black Pearl and Monster Bud in the Moonshine Mix:
Thanks in advance and a big thanks to all the great posters of this thread who inspired me to start off growing right - with a CMH bulb!!
