I just got my hands on a phototron it holds 3 U- shaped floressants, & one blue-specturm bulb at the top, are these good for growing indoor? I got 2 get 2 U-ones cuz 2 of the were busted when I got it, I found a place 2 get them, are Phototrons alright?
They were latest and greatest things in the seventies and plants still need the same things tp grow so it should work well.
