T8 are a little over half as bright and consume around just over half the amount of watts as T5’s when driven normally.
But T8 are just your standard florescent bulb, the T# denotes the size of the bulb and specifically the diameter mainly, but each one runs after different wattage’s, but typically the smaller the bulb the more efficient it is.
the sizing is as such though T12 = twelve / eights of an inch aka 1.5", T8 = 1", T5 = 5/8" and so on
use to run floro tubes a ways back, they worked well for me, also had over driven T8 in my shop at the time, couldn’t even tell it was night time till you stepped outside.
@Kalgrae you’ll have more than enough light now lol probably pulling about 480-500w from the wall, could even flower under it if running new bulbs, that fixture will be pretty warm though, saying that the bulbs wont last as long, but free is free
Thanks @Mr.Sparkle for chiming in. Appreciate it. Your diy lights and setups are really impressive! I had thought about them getting really hot since the bulbs are so close together and this morning am thinking to remove a couple and give them each about 1/2 inch space between them. Heat. Now I can use the heat, but this summer I won’t.
I’m also thinking to raise the ballasts slightly off the cover so a little air moves beneath them but still keep them grounded. Maybe it won’t matter and dry run them first to see what temps stay like.
She’s kind of ugly and scraggly looking but has a beautiful mysteriousness about her. I think @ganjajuana has one of the same phenos? Not a typical looking plant at all. Proper pics when she comes out for harvest.
Good stuff @Kalgrae bro, that spindly fkr will probably be potent as fk… lol.
What strain is it. . Have been able to put some outdoors or…?? I will pm you soon mate…
Happy growing/smoking ,
