So, someone gave me 2 old light systems.... a 4' and a 2'. There were unmarked bulbs in them. No brand name. They did have stickers that said "Full spectrum lights" on them. To me they just look like any old florescent light... like shop lights. They have the 2 pins at the end.
So, can I just pick any brand? And what about the "T" number? ( I have no understanding of that )
I plan to start ( should say "hope" ) to start my seeds and then use this system until May.... but I am planting my superhot peppers in December this year.
