looks good bro, I'll watch them babies grow. How old are they now?
yeah thats what you wanna go for, lots of light over a decent amount of plants. you are on the path to success. those will grow proper with fairly tight node spacing. only concern i can see now is maybe heat, they are probably fine though. i dunno if you have a thermo/hygrometer but it would be a worthy investment.
in regardes to the heating issue. i would like to know if this fan will be good enough for keeping the grow area cool enough with the room being b/t 80 - 85 degres. at lest cool enough till i get a thermometer
