thanks rebel .. the photo seedling is looking great .. this will be my first photo grow so i expect slower growth..i will look around the site and see if i find evidence of a nlxbb doing good under 18\6 to help make my decision ..yes since its summer my power bill has shot up 150$
i run 1 400w hps on 20\4
1 small ac unit
2 extraction fans
1 circulating fan
1 aerator pump mid size
1 seedling sead mat
thats why i need to get more seeds two plants dont justify that That cost BUT i enjoy this hobby .
