ok every body tumbstones are the light bulb connecters

and yes you can use a T 8 ballast if u know whats going on i put the tumb stone on it with tape and only used one side of the connecter because i got the skinny bulbs 1000 lumens each only two of them on a two bulb ballast working fine!!!!

and where i live if home depot and there are also lowes and k mart and walmart all sell the fixtures with T5 bulbs for around 20 spend a hundred and ull have a nice veg area

i bought these skinny bulbs for 5 each! just to try it!! and it worked i also found warm white full speatrum T5 and t8 also!

has any one ever herd of a fluro tube color chaud or something like that its pritty cool cause i didnt know they made warm bulbs in tubes!
