hey spoof,

i dont know why you would have penetration issues...see the buds on the lower left of this pic? they were 2 1/2' feet from the arrays for about a month. and while we did prune away some, they werent in direct light the whole time. I'd think with the cfls added you should do wonderful. just do some light(no pun intended lol) rotation to your plants, move a leaf here or there. we had an uneven canopy across three level lights and it worked out ok(of course it could be better but it was an f1 so we worked with it).

keep up the good work:thumbsup:
