Hi folks, We are renovating our sunroom room which is 2m x 5m (6' x
16') with full afternoon sun on the long side. Australian climate, similar
to Florida. My question is, would it be beneficial to include (say) 2 x
1.2m (4') fluoro fixtures in the ceiling with Grolux-type tubes, or would it
be pointless? Thanks for any replies.

Pretty pointless as plants need to be within inches of the tube to benefit.
Might be good so you can see at night !
