Don't worry about it David...You got some misleading advice...Grow with what you got, and if you have a problem...Shout out to me or Bobbong, and we will set you straight on your lighting. peace

p.s. I use general dollar store soil and add shultz peat moss and perlite from Wally's to the mix...50%/25%/25% good luck. Stop Worrying; And in the future you should be wary of taking all the advice offered to you. you have to wade through info, and decide from researching similar answers; Which answers are helpful to you and which to be wary of. you haven't really done anything wrong yet. Good Luck lw
